The Charles F. Richter Early Career Award Recipients
2012: Katsuichiro Goda
The Seismological Society of America (SSA) will honor Katsuichiro Goda for his prolific work to reduce earthquake risk around the world, awarding him the Charles Richter Early Career Award on April 17 at its annual meeting in Salt Lake City.
His multi-disciplinary background has allowed Goda, a lecturer in civil engineering at the University of Bristol and an adjunct professor of earth sciences at The University of Western Ontario, to contribute broadly in the fields of seismic risk assessment, management and mitigation.
“A particularly exciting aspect of Katsu Goda’s work is the way it cuts across boundaries between seismology and engineering,” said Gail M. Atkinson, professor of earth sciences at The University of Western Ontario. "He is well-positioned to make outstanding contributions to the global understanding of seismic hazards and risk, its management and mitigation strategies."
Though still early in his career, Goda has authored 50 papers on a wide range of topics, and many of his publications start by making a new contribution in ground-motion seismology, such as developing new ground-motion equations or formulations, then progress to explore the implications of those findings in engineering practice, such as for the nonlinear response of structures.
His published work includes the development of spatial correlations models for California and Japanese earthquake data, opening new avenues through which quantitative seismic loss estimation studies for urban areas can be carried out. He has also turned attention to lifecycle cost-benefit analysis of buildings with different strengths and energy dissipation devices (for example, tuned mass dampers and base isolation). His works on cost effective and socially acceptable seismic design methodologies, along with earthquake insurance portfolio analysis, point the way to practical solutions in risk mitigation.
Goda has demonstrated, for example, that financial incentives, such as tax cuts and subsidies, can cause a considerable reduction in risk to human and economic loss through a combination of installing seismic isolation devices and purchasing of earthquake insurance. His work allows risk analysts to capture the catastrophic physical nature of earthquake disasters, where significant damage happens to numerous stakeholders simultaneously, and facilitates the study of safe and cost-effective solutions by prioritizing mitigation efforts in more vulnerable areas.
Goda earned his master’s degree in agriculture from Kyoto University and his doctoral degree in civil engineering from The University of Western Ontario.
2011: David Shelly
David Shelly has quickly established himself as world leader in observational seismology, having already made a dramatic impact on the field of seismology through his pioneering work to detect and locate deep tectonic tremor. For his work, the Seismological Society of America will honor Shelly with its Charles. F. Richter Early Career Award, which honors outstanding contributions to the goals of the Society by a member early in her or his career.
While a graduate student at Stanford University, Shelly spent one summer in Japan at the University of Tokyo, where he studied a new class of low frequency earthquakes (LFE), which are tiny earthquakes observed almost exclusively during periods of deep tremor. In a groundbreaking paper published by the journal Nature, he described that the LFEs represented shear slip on the plate interface. In a subsequent paper, also published by Nature, he demonstrated that deep tremor consists of a swarm of LFEs, challenging the prevailing theory that suggested tremor was the signature of fluid movement.
As a Mendenhall Postdoctoral Fellow at the U.S. Geological Survey, Shelly focused his research on tremor under the San Andreas Fault, identifying a streak of low frequency earthquakes on the deep extension of the fault and demonstrating that the recurrence of LFEs changes with time.
His more recent papers have concentrated on the locations, physical mechanism, and temporal patterns of the tremor, which may reveal new information about the behavior of faults.
At the 2012 SSA annual meeting, Shelly discussed a new study that looks at recent earthquake swarms deep below Mammoth Mountain in California that offer a unique chance to see how volcanic processes operate in the Earth’s lower crust. He and his colleague David Hill of the U.S. Geological Survey collected and analyzed swarms of brittle-failure earthquake events underneath Mammoth Mountain—which sits on the edge
2010: Zhigang Peng
Zhigang Peng has made seismological discovery a regular occurrence early in his career. Peng has written 35 peer-reviewed papers that have contributed much to the understanding physics of earthquakes and faults.
An Assistant Professor in the School of Earth and Atmospheric Sciences at the Georgia Institute of Technology since 2006, Peng’s contributions to earthquake seismology have showcased the traits that have made him an impressive researcher. Peng identified many important physical problems that could be addressed by careful analysis of seismic data, and showed patience and diligence to comb through mountains of records to conduct the research, while also contributing to the understanding of earthquake triggering, non-volcanic tremor, and fault zone structure.
One of his recent papers, “Migration of early aftershocks following the 2004 Parkfield earthquake,” was published in Nature Geoscience in 2009. In that paper, Peng and his graduate research assistant Peng Zhao used a matched-filter technique to examine the aftershocks of the 2004 magnitude 6.0 earthquake along the Parkfield section of the San Andreas Fault. They found almost 11 times as many aftershocks than previously reported in a well-instrumented area. The findings lent credence to the idea that the aftershocks were the result of fault creeping. Currently Peng’s research group is applying this technique to several recent earthquake sequences in California, China, and Japan to detect more aftershocks, and use them to better understand the physical mechanisms of aftershock generation.
Another recent focus of his research is dynamic triggering of microearthquakes and tremor by large distant earthquakes. Working with many international groups, Peng found that dynamic triggering not only occur in plate-boundary regions in California and Taiwan, but also in many intraplate regions in China and elsewhere. In each region he documented conditions required for triggering – important benchmarks in the current struggle to understand tremor and triggering in general. These studies have broad implications, including a better understanding of earthquake nucleation and interaction over long distances.
In addition to continuing to conduct his own research, Peng has helped grow the Geophysics group at Georgia Tech. His leadership helped rebuild the group and attract quality graduate students. He is very active in providing service to the scientific community by organizing meetings and conference sessions, reviewing numerous papers and proposals, and recently serving as the Associate Editor of the Bulletin of the Seismological Society of America. His online tutorial on Seismic Analysis Code is one of the most widely used teaching materials. Peng has also been a frequent commenter in national and international media, educating the public about major seismological events as he did in 2008 following the Wenchuan earthquake in China, in 2010 following the Haiti earthquake, and recently following the magnitude 9 Japan earthquake.
2009: Karen Felzer
This award was presented to Karen Felzer, USGS Pasadena, at the 2010 annual meeting in Portland, Oregon. In her relatively young career, Felzer has produced transformative and sometimes valuably controversial research by utilizing statistical approaches to tackle tough seismological questions. Her oft-cited work has constructively challenged previously held theories and reshaped the way earthquake physics is understood. While completing her doctoral work at Harvard, Felzer produced three publications that focused on a statistical approach to earthquake clustering and provided a clearer view of how earthquake sequences work. She confirmed earlier work by others that foreshock-mainshock pairs are, statistically, simply cases where an aftershock is larger than the initial event. This led her to conclude that robust and useful calculations can be made of the probability that a given earthquake will be followed by a larger earthquake across a given time and distance using these empirical aftershock statistics. During her post-doc work, Felzer documented that studies of aftershock rates are often confounded by the inclusion of background events, which is a particular problem as one looks for distant aftershocks. Felzer has also been a key contributor to the Working Group on California Earthquake Probabilities. Among other contributions, she created a uniform, long-term seismicity catalog and then used this catalog to estimate expected seismicity rates. The drills developed for the Great Southern California ShakeOut relied on aftershock scenarios that Felzer produced.
2008: Miaki Ishii
This award was presented to Miaki Ishii, Harvard University, at the 2009 annual meeting in Monterey, CA. In her young career, Ishii, an assistant professor of earth and planetary science at Harvard University, has made two groundbreaking discoveries in geophysics that have fostered intense debate and subsequent research that has changed the understanding of deep Earth seismology.
Since she entered Harvard to begin her doctoral work in the late 1990s, Ishii has shown a knack for answering big questions. Shortly after her arrival at Harvard, she researched the driving force behind plate tectonics -- lateral variations in mantle density. The research inferred that the slowest parts of the lowermost mantle are denser than average, rather than lighter as most had assumed. The findings flew in the face of the long-held theory of a homogenized mantle and generated significant subsequent research and debate. Recent research is beginning to confirm Ishii’s observations.
Her second groundbreaking find built on her previous study with Harvard’s Adam Dziewonski. Ishii discovered what is now known as the “innermost inner core,” a region 300 kilometers in radius at the center of the Earth that has anisotropic properties distinct from the rest of the inner core.
In addition to her research, Ishii is known for her diligence and has shown a talent for presenting her research well -- a talent that earned her Student Paper Awards from the American Geophysical Union in 1998 and 1999.
2006: Jeanne Hardebeck
This award was presented to Jeanne Hardebeck, USGS, Menlo Park, at the 2007 annual meeting. The Richter Committee noted that, "Hardebeck's contributions to seismological research have been aimed at the central issues in earthquake studies including especially the state of stress and the strengths of faults, problems that have been persistently clouded by speculation and poor quality data. We are highly impressed by her innovative, insightful and unusually thorough work. Her accomplishments include the development of new investigative methods, such as better ways to determine focal mechanisms and stress orientation, methods that have been adopted by others in the seismic community, including people who are themselves experts in such analysis.
In addition, Jeanne Hardebeck's career is notable for her work on practical problems such as fault structure in the Bay Area and the careful USGS investigation following the San Simeon earthquake. Jeanne works well in collaboration with others and often takes intellectual leadership . She is also an excellent speaker, and has stood her ground on a number of strongly debated issues."
2005: Emily Brodsky
Dr. Emily Brodsky of the University of California, Santa Cruz, has been selected to be the first winner of the Charles F. Richter Early Career Award.
The Richter committee was impressed by the breadth and innovative aspects of Emily Brodsky's research, which is broadly focused on elucidating "how earthquakes, volcanoes and landslides work." She is cited for contributions to (1) earthquake triggering and distant effects of earthquakes, (2) rectified diffusion theory, and (3) fault lubrication theory (fluid pressurization). In her approach to these topics she has been taking full advantage of her strength in physics and fluid mechanics to understand the dynamic processes involved in these systems. For example, she has focused on understanding the nonlinear response of the crust to dynamic stress changes caused by the passage of seismic waves, to account for remotely triggered seismic, volcanic, and hydrologic activity. This is a very exciting and fruitful area, and she is already one of the dominant researchers in this field. She nicely complements theoretical work with data analysis and observational constraints. Only 5 years past her PhD at the time of her selection, she had published 13 papers, 6 as first author.
Emily Brodsky is unusually engaged in science. She takes on challenging projects, presents innovative and sometimes controversial hypotheses, and seeks debate in which she is eager to evaluate and consider any challenges to her initial ideas. Emily Brodsky is a worthy and exceptional young scientist who is a fitting first recipient of the Charles F. Richter Early Career Award.
