Meeting of the Central and Eastern U.S. (CEUS) Earthquake Hazards Program October 28–29, 2009

On October 28th and 29th, 2009, the U.S. Geological Survey Earthquake Hazards Program held a meeting of Central and Eastern United States investigators and interested parties in Memphis, Tennessee. The purpose of the meeting was to bring together the Central and Eastern United States earthquake-hazards community to present and discuss recent research results, to promote communication and collaboration, to garner input regarding future research priorities, to inform the community about research opportunities afforded by the 2010–2012 arrival of EarthScope/USArray in the central United States, and to discuss plans for the upcoming bicentennial of the 1811–1812 New Madrid earthquakes. The two-day meeting included several keynote speakers, oral and poster presentations by attendees, and breakout sessions. The meeting is summarized in this report and can be subdivided into four primary sections: (1) summaries of breakout discussion groups; (2) list of meeting participants; (3) submitted abstracts; and (4) slide presentations. The abstracts and slides are included “as submitted” by the meeting participants and have not been subject to any formal peer review process; information contained in these sections reflects the opinions of the presenter at the time of the meeting and does not constitute endorsement by the U.S. Geological Survey.

Liquefaction and foundation failure of Chevron oil and gasoline tanks at Moss Landing, California

Liquefaction of gray, coarse‐ to medium‐grained, esturine sand during the October 17, 1989 Loma Prieta (Ms=7.1) earthquake led to foundation failures of oil and tanks at the Chevron Marine Station at Moss Landing located about 25 km south‐southeast of the epicenter. Differential settlement of the foundations resulted in 1° to 6° of the tanks towards one another and an associated 2° to 7° inclination of tank piping. In addition, sand was vented around the bases of the tanks that contained the most oil and adjacent cracks. Liquefaction and related ground failure was not restricted to the vicinity of the Chevron tanks but was a widespread phenomenon at Moss Landing. Analysis of geological and geotechnical data at sites such as the Chevron Marine Station will serve to check and to advance current methods of assessing liquefaction potential at a site and of mapping liquefaction hazard on a regional scale.
