Anthony F. Shakal Receives the 2014 Bruce Bolt Medal


Anthony Shakal (M. EERI, 1980), California Geological Survey (CGS) Supervising Geologist/Program Manager, was chosen as the 2014 recipient of the Bruce A. Bolt Medal, which is awarded jointly by the Seismological Society of America, the Consortium of Organizations for Strong-Motion Observation Systems (COSMOS), and EERI.

The Bruce A. Bolt Medal was established 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. Professor Bolt was recognized in his time by earthquake engineers and seismologists worldwide as the expert in engineering seismology.

Dr. Shakal has been associated with the CGS’s Strong Motion Instrumentation Program (SMIP) for the past 32 years, and has successfully grown and led the Program for the past 27 years. Under Dr. Shakal’s direct supervision and innovative management, the SMIP operates the largest and most advanced strong-motion network in the United States. The SMIP is also the largest strong-motion component in the U.S. Geological Survey’s Advanced National Seismic System. In 2006 at the commemoration of the Great 1906 San Francisco Earthquake, the SMIP received the Applied Technology Council/Engineering News Record joint award as the Best Seismic Program of the Twentieth Century.

To date, Dr. Shakal’s SMIP group has installed over 5000 accelerometers at nearly 1200 stations around the State. These seismic monitors have been placed in over 850 free-field ground stations, on more than 80 bridges, and in 200 buildings. Ground motion and structural response data gathered from this network are directly employed in the California Building Code to make structures more earthquake resilient. Two very recent examples of Dr. Shakal’s diverse skills can be seen in the successful completions of the One Rincon Tower and the new east span of the Oakland Bay Bridge.

Dr. Shakal continues to expand and promote the educational and communication links between the structural engineering and seismological communities through financially supporting an annual conference in which SMIP-sponsored research papers are presented. (SMIP13 was in Los Angeles, California.) He participates as an active member of the standards setting committee at COSMOS, and works closely with Caltrans, and the Office of Statewide Health Planning and Development on projects related to earthquake engineering for hospitals. Dr. Shakal also finds time to write technical research papers to help publicize the latest findings from the programs he oversees.

Dr. Shakal received his medal at the 2014 COSMOS Technical Session held on Friday, November 14, at the Crowne Plaza Hotel at the San Francisco Airport.


Debut of the COSMOS Network Forums

In cooperation with the U.S. Geological Survey and the California Geological survery, development of the COSMOS Bulletin Board forum (called the COSMOS Network Forums) and Wiki page has just been completed! It can be found here:

COSMOS Network Forums (

We invite those international strong-motion network providers that attended the COSMOS Strong-Motion Forum at the 15th World Conference on Earthquake Engineering in Lisbon, Portugal, to join!


COSMOS is a non-profit organization whose goal is to expand and significantly modernize the acquisition and application of strong-motion data in order to increase public safety from earthquakes.
