2016 Call for Nominations for the Bruce Bolt Medal

The Bruce Bolt Medal is awarded jointly by COSMOS, EERI, and SSA to recognize individuals worldwide whose accomplishments involve the promotion and use of strong-motion earthquake data and whose leadership in the transfer of scientific and engineering knowledge into practice or policy has led to improved seismic safety.

Members of EERI, SSA, and COSMOS are encouraged to submit nomination packages for this distinguished award. Nominations will be reviewed in confidence by a six-person Joint Nomination Panel formed by two representatives from each of the three sponsoring organizations.. The recommended nominee will be considered in confidence by each organizationís Board of Directors for their approval and joint selection of the medalist.

The following criteria are used to evaluate the recipient:

  • Promotion of strong-motion instrumentation or advancing strong-motion data processing or data utilization;
  • Technical contributions in seismic engineering or engineering seismology; and
  • Leadership in the transfer of knowledge into practice or policy that has led to improved seismic safety.

The Joint Nomination Panel is charged with applying these criteria to select a nominee worthy of the high level of professional recognition represented by the sponsorship of the Bruce Bolt Medal by SSA, COSMOS, and EERI. Please note that current members of the Joint Panel are not eligible for nomination; the names of the current panelists are posted on the SSA, COSMOS, and EERI web sites.

The nomination letter, which should be no longer than two pages, must address the ways in which the candidate meets all three of the criteria. Along with the signed letter, the nomination package must include a substantial summary of the professional history of the candidate including employment, significant publications, honors, and activities and accomplishments relevant to the Bolt Medal criteria. The current contact information for the candidate must also be supplied. Up to three signed supporting letters (each no longer than two pages) may be included in the nomination package. Such letters should include a personal perspective on the nominee and his/her sustained impact on the field.

The closing date for submitting nominations is October 31, 2015.

Incomplete nomination packages will not be considered by the Joint Nomination Panel. Nomination packages (preferably as one combined .pdf file) for the Bruce Bolt Medal should be sent to the Bolt Medal Nomination Panel, in care of William (Woody) Savage at Questions regarding the Bolt Medal criteria or the nomination process for candidates may be directed to Woody at the above e-mail address. While electronic submissions are preferred, in .pdf or .doc formats, hard copies may be sent to the following postal address: Bolt Medal Nomination Panel, In Care of Woody Savage, 1930 Village Center Circle #3-292, Las Vegas, NV 89134. If a hard copy is sent, the sender should notify Woody by e-mail.

Organization affiliates are as follows: EERI: Charles R. Real and Robert L. Nigbor; SSA: Robert R. Youngs and Jose A. Martinez-Cruzado; and COSMOS: Maurice S. Power and William U. Savage

John G. Anderson Awarded the 2015 Bruce A. Bolt Medal

John Anderson, Professor of Geophysics at the University of Nevada at Reno (UNR), is the recipient of the 2015 Bruce A. Bolt Medal. Jointly awarded annually by SSA, EERI, and COSMOS, this medal recognizes individuals worldwide whose accomplishments involve the promotion and use of strong-motion earthquake data and whose leadership in the transfer of scientific and engineering knowledge into practice or policy has led to improved seismic safety.

One of John Andersonís first publications in 1979 estimated the earthquake recurrence rate on a fault by incorporating how much a fault slips each year, a novel approach to examining seismicity that foreshadowed the impact of his research on seismic hazard assessment. Anderson, a professor of geophysics at the University of Nevada at Reno (UNR), has contributed to all aspects of engineering seismology, including the physical processes controlling strong ground motion and applications of geological and seismological information to estimate seismicity and seismic hazards. For his work, Anderson will be honored with the Bruce A. Bolt Medal, which recognizes individuals who use strong-motion earthquake data and transfer scientific and engineering knowledge into practice or policy for improved seismic safety. The honor is a joint award given by the Consortium of Organizations for Strong-Motion Observation Systems, the Earthquake Engineering Research Institute and the Seismological Society of America.

Prior to UNR, Anderson earned his doctorate at Columbia University and held research positions at the California Institute of Technology, University of Southern California and University of California at San Diego. With more than 180 publications during his career, Andersonís work reflects all aspects of observational and theoretical ground-motion seismology and seismic hazard estimation. His 1984 paper, co-authored with Susan Hough, introduced kappa as a parameter in the description of high-frequency acceleration spectra. Later papers presented ground-motion prediction equations, probabilistic seismic hazard analysis and the use of precariously balanced rocks and other fragile geological features for testing the predictions of likely ground motion from future earthquakes.

During his 27-year tenure at UNR, Anderson has focused on ground-motion data of major earthquakes, while also serving as director of the Nevada Seismological Lab at UNR for 11 years and as a member of the Nevada Earthquake Safety Council and various national committees. Currently he is chairing the National Steering Committee forNational Seismic Hazard and Risk Assessment in support of the U.S. Geological Survey National Seismic Hazard Maps. Anderson participated in the development of the National Seismic Hazard Maps for the 1996, 2002, 2008, and 2014 revisions. For the 1996 maps Anderson advocated use of early geodetic evidence for a zone of increased activity in the Nevada region that boosted the hazard of Reno above that of the Central Nevada Seismic Zone, even though that zone had ruptured most recently in a sequence of M7-class earthquakes from 1915-1954. Subsequent geodetic and geologic research has confirmed this recommendation. It was not until the 2014 maps that geodetic data was sufficient to be used in a major, systematic way to develop the seismicity models for a large region, specifically all of California, with lesser influence in the rest of the western United States. The impact of Andersonís work spans the world, contributing to the installation of strong motion networks in Mexico, Turkey, Los Angeles and the Eastern U.S., collaborations to interpret data from those networks, and research collaborations with numerous scientists in Japan and other Asian countries, Latin America, and Europe.

The Bolt Medal is presented to the recipient at the annual meeting of the recipientís choice among the three sponsoring organizations. Anderson will receive his award at the SSA Annual Meeting to be held April 21Ė23 in Pasadena, California.
