By Paul PreussThe little town of Parkfield, population 34, sits halfway between San Francisco and Los Angeles in dry ranching country, about as far from a population center as you can get on the San Andreas Fault. Which is lucky, because modern scientific measurements and the historical record both indicate that Parkfield has the highest likelihood anywhere in the country of experiencing an earthquake of magnitude 6 or higher.
Now Robert Nadeau and Thomas McEvilly of the Earth Sciences Division report that clusters of identically repeating tiny earthquakes near Parkfield can be timed to reveal the rate at which the great North American and Pacific tectonic plates are grinding past each other deep within the earth. The timing of these "tickers" may provide a new way to monitor the buildup of deep fault strain that is associated with large earthquakes.
The two geophysicists reported their findings, based on new analyses of high-resolution data, in the July 30 issue of Science magazine. Because magnitude 6 shocks have occurred near Parkfield at regular intervals in the past, the area has been a center of seismic study by the U.S. Geological Survey and other institutions since 1987.
"Between 1857 and 1966, quakes of magnitude 6 occurred at Parkfield an average of every 22 years. Despite expectations, there hasn't been another one since 1966," Nadeau says. "However, a build-up of activity started in October of 1992 and persisted through 1994, including four events ranging in magnitude from 4.2 to 5."
"We have since found a highly organized relationship between the intervals of individual microearthquakes in clusters, the occurrence of the larger events, and changes in fault slip on the surface," Nadeau says.
The 1992-94 events and the magnitude 6 earthquakes of the previous century all started within the same eight-kilometer strip of the fault. They resulted from sudden releases of strain built up between the rocks of the Pacific Plate to the west, which is gradually but intermittently sliding northward, and the North American plate to the east.
Historically, the larger the earthquake, the more widespread the slippage. Slippage doesn't start at the surface epicenter, however, but at the quake's hypocenter, which in the Parkfield region is typically 8 to 10 kilometers beneath the surface. Hypocenters can be pinpointed in three dimensions to within a few meters by comparing the arrival times of seismic waves as they come in at a different seismometers.
At Parkfield some seismometers are placed at the bottom of boreholes 200 to 300 meters deep. "There's a lot less noise in the data than with surface seismometers, so we can detect many more quakes and smaller quakes," Nadeau says. "We can also measure earthquake vibration across a wide range of frequencies, which allows us to see much more detail in the behavior of the quakes."
Over time, some two-thirds of all the seismic activity in the Parkfield region has been organized into about 300 localized clusters of microearthquakes. "We identified 160 sequences within these clusters, each with three or more repeating quakes." In the model developed by Nadeau and McEvilly, these clusters represent small, strongly locked regions where strain repeatedly builds up and is released.
"Then we looked at how the recurrence of intervals between quakes in each sequence changed over time," Nadeau says. He and McEvilly hypothesized that shorter and shorter recurrence intervals indicated accelerating fault slippage and that when intervals got longer, slippage was slowing down.
They also found good agreement between the seismic data and direct measurements of slippage on the surface, made by creepmeters looking across the fault. Where large parts of the fault are locked, as in the region where the magnitude 6 quakes were centered, an increase in the repetition rate in specific clusters means that the strain load is building faster. When it reaches a critical level, a swarm of medium-sized quakes may dissipate the load, or a single larger event may do so.
By looking at an 11-year collection of data, Nadeau and McEvilly were able to track a zone of accelerated slippage as it moved along the fault from northwest to southeast. When this traveling zone of strain reached the hypocenters of the past magnitude 6 quakes in 1992, it apparently triggered the subsequent magnitude 4-plus events.
Nadeau and McEvilly suggest that these events may have occurred in response to the "pulse" of increased slip rate deep in the fault; the beginning of the pulse was detected prior to the events, but once it passed through the region, the larger quakes stopped.
The persistent, distinctive signatures of individual clusters of microearthquakes and the changes in intervals between them provide a new means of correlating measurements taken near the surface of the San Andreas Fault with slip rates from two to 10 kilometers below the surface. Brown University geophysicist Terry Tullis, in an article in the July 30 issue of Science, compares Nadeau and McEvilly's method to "a creepmeter installed across the fault at a depth of 10 km," showing "that if we look at the fault zone carefully enough we can learn things that we never expected to find."
While Nadeau found a way to use data on the recurrence of micro-earthquake clusters to determine slip rates at depth in the Parkfield region, it remains to be seen whether this kind of intriguing correlation exists in other fault zones, and whether it can be used over longer periods of time and space to warn us of damaging earthquakes. But preliminary results using small repeating earthquakes on the Hayward Fault, which cuts across the base of the hill on which Berkeley Lab stands, "are already showing promise."
More information about earthquake monitoring in the Parkfield region can be found on the web at http://quake. wr.usgs.gov/QUAKES/Parkfield/. Nadeaus's and McEvilly's strategy for using the timing of clusters of microearthquakes to gauge fault slippage at depth is discussed at http://www.seismo.berkeley.edu/seismo/annual_report/ar97_98/node15.html.
A voyage of exploration that began in mid-July inside living cells and moved in subsequent weeks to the genes of the fruit fly, the annihilation and recreation of matter and antimatter, and exploding supernovae at the edge of an expanding cosmos, ended on Aug. 4 with a journey toward the center of the Earth. The last of the Public Information Department's Summer Lecture Series for 1999 was presented by Don DePaolo of the Earth Sciences Division, who described a project to drill through the basement of a Hawaiian volcano in order to learn more about the Earth's interior. (See Page 5 for more.)
It was Carolyn Larabell of the Life Sciences Division who launched the series on July 7 with a talk on "Imaging the Cellular Universe: Comets, Particles, and Transfer Phenomena." (See Currents, July 16, 1999.) Not only do advances in electron microscopy yield still pictures of startling magnification and resolution, she explained, but the advent of synchrotron x-ray microscopy allows photography of hydrated cells, permitting live-action movies of biochemical cascades and such strange mechanisms as "comets" that propel essential chemicals as well as unwanted bacteria through the cell interior.
On July 14, Gerald Rubin, also of Life Sciences, showed pictures that were startling in a different way. In his talk on "The Fruit Fly and the Human Genome: a Rosetta Stone," Rubin -- the codirector of the Drosophila Genome Center and a professor of genetics at UC Berkeley -- exhibited closeups of a fly's eye with huge cancerous tentacles growing where normal lens components should be. This and other deformities he discussed were caused by genetic defects correctable with gene therapy.
In the case of flies born wingless, the therapy consists of replacing defective fly genes with human genes, which restored the ability of subsequent fly generations to sprout wings.
The sequences of many human genes are remarkably similar to those of the fruit-fly, leading to similarities in protein structure. Thus the genomes of fruit flies and humans are truly a Rosetta Stone, in which the hieroglyphics of the human genome can be translated into the demotic script of a fruit fly's 10-day life cycle. Decryption promises discoveries of genes that control cell growth and other functions in these and many other species.
There was a note of parental pride in Pier Oddone's July 21 talk on the "Asymmetric B Factory: Reflecting the World in the CP Mirror." The new collider, up and running this spring at the Stanford Linear Accelerator Center (SLAC), is based on a principle that Oddone, now the Lab's deputy director, proposed in 1987.
When beams of equal energy collide, the dense, centralized collisions hide many details. But by colliding a beam of electrons with a beam of positrons only a third as energetic, Oddone suggested, the products of these matter-antimatter annihilations could be swept "downstream," spread apart so that differences in their lifetimes and other features are easier to see.
The B Factory's energetic asymmetrical beams create B mesons -- massive bottom quarks paired with their antiquarks -- in copious amounts; by observing the effects of the weak force on their myriad decay products in the BaBar detector, researchers hope to eke out the secrets of phenomena which presumably allowed ordinary matter to persist in the early universe instead of immediately vanishing in annihilations with antimatter. (For more on the B Factory, see the Nov. 6, 1998 and June 4, 1999 issues of Currents.)
In his July 28 talk on "Supernovae and the Expanding Universe," Gerson Goldhaber of the Physics Division and the Supernova Cosmology Project discussed the dramatic discovery that was selected by Science magazine as its "Breakthrough of the Year" for 1998 (see Currents, Dec. 18, 1998.)
Goldhaber explained that Type 1a supernovae are so bright and so much alike in light characteristics because they are formed when a white dwarf star sucks enough mass from a companion star to collapse into a black hole -- thus their masses and compositions are all similar. This makes them excellent "standard candles," he said, whose distance can be calibrated no matter where they occur in the universe. Goldhaber demonstrated the methods by which the Supernova Cosmology Project can quickly produce "supernovae on demand" with a few days of telescope time, and showed how redshifts of distant objects can be used to measure the expansion of the universe directly.
Finally, Goldhaber discussed plots of supernova distance and redshifts that indicate that the universe is not only expanding, but that the expansion rate is accelerating, compelling evidence for some form of cosmic "dark energy" that opposes gravity.
In the final lecture of the series on Aug. 4, Don DePaolo of the Earth Sciences Division, head of the Center for Isotope Geochemistry and a professor of geophysics at UC Berkeley, described the Hawaii Scientific Drilling Project. Investigations of the deep Earth are being conducted by drilling a hole deeper than the ocean through the lava underlying the island of Hawaii. Analysis of rock cores brought up from the hole will shed clues on their age and origin in the depths of the mantle and the history of the island they formed. (See sidebar.)
Berkeley Lab's annual Summer Lecture Series is geared for audiences who love knowledge but may not necessarily be specialists, and features Lab researchers whose work at the frontiers of science often makes the front pages of national and international newspapers. Its continued success, confirmed by the capacity crowds that usually filled the Bldg. 50 auditorium, makes it a good bet that the series will be back for a return engagement next summer.

Recent national news reports about the scientific misconduct investigations of a former scientist at Berkeley Lab have focused the attention of the research community on the importance of scientific integrity and responsibility.
Since Science magazine first reported the investigation and subsequent scientific misconduct findings against Dr. Robert Liburdy in its July 2 issue, the Laboratory has been responding to public and media inquiries about the case. Although Berkeley Lab's own investigation is more than four years old, it was the published conclusions of the federal Office of Research Integrity (ORI), a branch of the Department of Health and Human Services, on June 17 that generated the interest.
In essence, the ORI validated the Laboratory's assessment that Liburdy, who was employed by the Laboratory for 15 years until he resigned last March, "engaged in scientific misconduct ... by intentionally falsifying and fabricating data and claims" on how electromagnetic fields (EMF) affect living cells. These data and claims were reported in two scientific papers published in 1992.
Liburdy's work was among the first to offer a plausible mechanism for a possible link between EMF exposure -- the kind shed by power lines and home appliances -- and calcium signaling, a fundamental cell process governing many important cellular functions. These results were interpreted to mean that there was a proven correlation between EMF and a number of cancers.
An agreement with ORI indicated that Liburdy was to retract certain figures in the two papers and not receive federal funds for three years, but also that he "neither admits nor denies ORI's findings of scientific misconduct."
Last week, the National Cancer Institute (a division of National Institutes of Health) asked the Lab and the University of California to repay $804,000 that it says was misspent as part of Liburdy's research in 1991-94. The Laboratory has said it will appeal the decision, indicating that the Lab's aggressive pursuit of the misconduct charges was responsible institutional behavior that should not be penalized through a financial assessment.
In light of the publicity that surrounded ORI's report, Life Sciences Division Director Mina Bissell issued a memo to her scientific staff, which cautioned, "We all have to be aware not to exercise prejudice in any area of science but rather to interpret and present data correctly."
She continued, "It is important to remind ourselves that scientists in every institution and at all levels need to police themselves. As you know, there have always been a few who have a tendency to exaggerate and misinterpret data, and at times even fake it (knowingly or unconsciously). I cannot stress enough that our high standards must be maintained. We all must be vigilant in our own research, but also in insuring that our colleagues are taken to task if the evidence warrants."
Some media reports misstated certain aspects of the Liburdy case. In one instance, it was suggested that a whistle-blower alerted the ORI to the issue and triggered the investigation. In fact, Berkeley Lab initiated its own probe back in 1994, alerted ORI in 1995, and submitted its conclusions to ORI in 1997. In a letter to the New York Times, Laboratory Director Charles Shank noted the Lab's perseverance in pursuing the matter and that "throughout, the guiding principle has been the integrity of the science, and I take full responsibility for pursuing it vigorously."
Another published error had to do with disposition of the unspent portion of the funding that supported Liburdy's research. As is routine practice, unused funds in such cases are not retained by the Laboratory but are returned to the federal government. This was reflected in a letter from Director Bissell to Liburdy in April of 1998, which stated, "The Laboratory will relinquish interest in any remaining grant or contract funds, and unexpended balances will be returned to your research sponsors."

Richardson to Ask Clinton to Veto New Security Agency
Energy Secretary Bill Rich-ardson would recommend that President Clinton veto a proposal passed by a House-Senate conference to create a National Nuclear Security Administration. Under the proposal crafted by House Republicans, the agency would be semiautono-mous within the DOE. The Secretary supports the establishment of an under-secretary position to oversee nuclear weapons activities, but does not want this official to set policy.
A spokesperson said Richardson will ask for a veto of the proposed legislation in its present form. The Secretary says the reorganization would reduce his authority and give too much authority to the new under-secretary.
Changing Faces on the National Lab Scene
Yoon Chang, associate laboratory director for engineering research at Argonne National Laboratory, has assumed ANL's interim directorship. He replaces Frank Fradin, who has served as the Lab's interim director since August 1998, when Dean Eastman stepped down to return to teaching.
At Oak Ridge National Laboratory, Director Alvin Trivelpiece, head of ORNL since 1989, has announced that he will step down next March.
Texan Is House Science Panel's New Ranking Democrat
Rep. Ralph Hall of Texas has replaced the late Rep. George Brown (D-Calif), who died last month, as the ranking Democrat on the House Science Committee. He will also continue to serve as ranking Democrat on the House Commerce Energy and Power Subcommittee.
DOE Issues Draft EIS on Yucca Mountain
The Department of Energy has released a draft environmental impact statement on the projected consequences of building a high-level nuclear waste repository at Yucca Mountain. The EIS also examines the projected consequences of not building the repository and allowing the waste to accumulate at existing DOE and commercial sites. The DOE will accept public comments on the statement starting today and until Feb. 9, 2000. It will also conduct 16 public hearings during the 180-day comment period, including nine in Nevada. The draft EIS is available on the Internet at http://www.ymp.gov or by calling DOE at (800)967-3477.

A new type of biological probe developed by Berkeley Lab scientists has been commercially licensed by a start-up firm in Palo Alto. Last fall, Lab researchers announced they had found a way to use nanometer-sized crystals of semiconductors, such as cadmium selenide and cadmium sulfide, as highly effective fluorescent probes for labeling and measuring biological molecules. (See Currents, Oct. 10, 1998) Now, through the Lab's Technology Transfer Department, the technology has been exclusively licensed to the Quantum Dot Corporation for use in biological assays.
The firm, which started up expressly to develop and commercialize this technology, also has a non-exclusive license to manufacture semiconducting nanocrystals as molecular-scale LEDs (light-emitting diodes) and transistors.
As part of the licensing transaction, the University of California, through Berkeley Lab, has been issued shares in the Quantum Dot Corporation as part of the licensing fees.
"Taking equity is a win-win situation for the company and the Lab," says Tech Transfer's Viviana Wolinsky, who negotiated the deal. "It allows Quantum Dot to devote more of its initial capital to moving the technology forward, and gives Berkeley Lab the prospect of significant financial returns."
In addition to the licensing agreement with Berkeley Lab, the Quantum Dot Corporation also sought and licensed complimentary nanocrystal technology from MIT and the University of Melbourne.
Semiconductor nanocrystal fluorescent probes (dubbed "Qdotsreg." by the Quantum Dot Corporation) offer a distinct advantage over conventional dye-molecules in that they emit multiple colors of light, which means they can be used to label and measure several biological molecules simultaneously. The unique optical properties of these semiconductor nanocrystals also hint at the possibility of observing changes that take place in labeled biological systems, such as living cells, over a period of time.
Development of the original semiconductor nanocrystal fluorescent probe technology was led by Paul Alivisatos and Shimon Weiss. Alivi-satos is an expert in the production by chemical means of semiconductor nanocrystals, simple inorganic solids consisting of a hundred to a hundred thousand atoms. He holds a joint appointment as a senior staff scientist with Berkeley Lab's Materials Sciences Division (MSD) and as a professor of chemistry at UC Berkeley. Weiss, a staff scientist with MSD, is an authority on single molecule fluorescence and spectroscopy.
"The development of semiconductor nanocrystals for biological labeling gives biologists an entire new class of fluorescent probes for which no small organic molecule equivalent exists," said Weiss at the time the research was first announced."These nanocrystal probes can be complementary, and in some cases may be superior to existing fluorophores."
The Hawaiian Islands are the remnants of volcanoes that have moved over the biggest plume of hot rock on the planet. Unlike the more common volcanic activity produced by mid-ocean ridges or the subduction of continental crust, these islands are being formed by plumes thought to originate at the Earth's core-mantle boundary, some 3000 kilometers beneath the surface. As a volcano moves across the plume, the chemistry and other characteristics of the lava that feeds it change, giving scientists an insight into the region's geological history.
The Big Island itself is an agglomeration of five different volcanoes: those to the northwest, now extinct, those very active to the southeast, as well as a growing seamount, Loihi, still underwater offshore.
The drilling site sits near the Hilo airport, which DePaolo says is an excellent location for both scientific and practical reasons (including ease of getting a drilling permit, in a mere two-and-a-half years). Aside from an overlay from a 1,400-year-old Mauna Loa lava flow, the lava beneath the drill site is from Mauna Kea.
Islands grow as lava is first deposited faster than its accumulated weight pushes down on the ocean floor; but as lava production falls off, they sink again. The sea level constantly changes and can be tracked by the drilling project, which has encountered black sand beaches hundreds of meters down, and even coral reefs, previously thought not to form on the flanks of active volcanoes.
The lava flow process, DePaolo said, closely resembes that of a liquid heated from below, with every fraction of a second for the liquid corresponding to a few million years of geological upheaval.
As the project drills deeper it goes back in time: first sampling the last lavas deposited as Mauna Kea moved off the plume, then moving down to lavas from the center of the plume (differently composed and deposited faster and in greater volume), and next reaching lavas deposited as the volcano encountered the plume's leading edge. Finally, the borehole may even drill to the ocean crust.
DePaolo expects a wealth of new knowledge to be generated by this unique project over the next four or five year as the drilling moves down from the current depth of 7,289 feet -- at lecture time -- to an eventual target of 20,000 feet.
By Allan ChenEvery spring volunteers throughout the country assemble at the homes of low-income, disabled or elderly people to paint, make repairs, and otherwise renovate homes whose occupants don't have the means to maintain them themselves. Now, thanks to the efforts of a former postdoc from the Lab's Environmental Energy Technologies Division and a group of volunteers from EETD and the local community, the effort will now also be able to incorporate energy efficiency improvements into its activities.
Called Christmas in April, the charity is a nationwide community service program operated by volunteers and supported by donations from corporations, businesses, civic organizations, foundations, neighborhood associations and individuals. In addition to fixing private homes, the organization also rehabilitates public and nonprofit facilities that serve the community.
Last April, a group of 27 volunteers, including a contingent from Berkeley Lab's EETD division, formed a special "energy team" for the Albany-Berkeley-Emeryville chapter's day of renovation. Held on April 24, the team was organized by Lisa Gartland, a former postdoctoral student and the current head of PositivEnergy, an Oakland-based consulting firm specializing in community energy conservation.
Gartland was initially hired to write a guidebook specifically for Christmas in April volunteers on how to make homes more energy-efficient. While working on the guidebook, she met with the director of the Albany-Berkeley-Emeryville chapter and attended "house captain" meetings.
"After interviewing a number of house captains of Christmas in April teams," she says, "I realized that these people are often too busy just organizing their volunteer teams and scoping out the repairs to give much thought to energy efficiency, even though many were enthusiastic about incorporating basic efficiency improvements into their plans."
Moreover, the cost of materials and equipment for implementing energy efficiency measures could be prohibitive for an organization that relies on donated materials. Even with a guidebook, energy efficiency improvements could easily get left at the door.
To show that making energy efficiency improvements could be a part of Christmas in April activities, Gartland volunteered to organize the energy efficiency team herself. She recruited 27 people, including nine of her colleagues at the Lab as well as friends and neighbors. She also raised 3,000 dollars' worth of materials and ran four training sessions for the volunteers. Donors included the City of Berkeley's Weatherization Program, the East Bay Municipal Utilities District, PostivEnergy, and RSA Corporation.
On April 24, efficiency team members visited 30 houses. They installed compact fluorescent lamps and water heater blankets, sealed pipes, weatherstripped doors and windows, replaced thermostats, and insulated heaters. They also caulked gaps around water pipes and behind electrical outlets and made houses more water-efficient by installing low-flow showerheads, water aerators and toilet flow reduction bags.
Said EETD's Rick Diamond after his volunteer stint, "The energy team is a great model for how other Christmas in April communities can include energy retrofits in their renovation activities. We will be working through Rebuild America to champion the energy work at the national level."
Rebuild America is a Department of Energy program that funds energy-efficient retrofits in local communities. EETD receives Rebuild America funding to provide energy-efficient design assistance to local communities performing efficiency retrofits.
Gartland estimated that implementation of these measures saved occupants about $60 per house per year, or a total of $420 per house over the life of the installed technologies.
In addition to finishing the energy efficiency guidebook, Gartland is developing a website for Christmas in April volunteers on how to organize energy efficiency teams in the hope that energy efficiency will become a routine part of future events nationwide. Next she plans to attend the annual Christmas in April conference in September in Saint Louis to discuss the energy efficiency team concept and to try to get energy efficiency team organized elsewhere in the United States.
For information on volunteering for Christmas in April, contact the organization at 644-8980. The energy efficiency guidebook, which includes pictures from the April event, is posted on the web at http://www.california.com/~positivenergy/xina.
