SRL: 2017 Model Predicts Significant Chance of Earthquake Damage in the Central and Eastern U.S.


1 March 2017-- A one-year seismic hazard model for 2017, from the U.S. Geological Survey, forecasts lower damaging ground shaking levels in the central and eastern U.S. compared to the previous forecast. Despite the recent drop in earthquake rates, Oklahoma and southern Kansas still face a significant risk of induced earthquake damage in 2017, according to the USGS report published March 1 in the journal Seismological Research Letters

BSSA: Las Vegas Site Classifications Could Lower Costs

28 February 2017-- Results of a massive new project to map and classify the earthquake shaking potential across most of the Las Vegas metropolitan area will help developers there build in safer and less expensive ways. The "Parcel Map" described 28 February in the Bulletin of the Seismological Society of America is the most extensive effort to date in the United States to map and classify soils based on their effects on earthquake shaking across an entire urban area with systematic, direct measurements at high density.

SRL: Non-Reporting DYFI Areas Can Improve Intensity Maps

1 February 2017–The remarkable reach of the U.S. Geological Survey's "Did You Feel It?" website can be used to improve maps of earthquake intensity-if non-reporting areas are including in the mapping analysis, according to a new study published online February 1 in the journal Seismological Research Letters.

BSSA: North Korean Seismic Event of May 2010 Likely Was Earthquake

North Korea seismicity

20 December 2016 - A tiny seismic event that occurred in North Korea on 12 May 2010 appears to have been an earthquake rather than a small underground nuclear explosion, according to a new analysis published 20 December in BSSA.

The new study led by seismologists from Columbia University's Lamont-Doherty Earth Observatory contradicts the findings of a 2015 report which concluded that the magnitude 1.5 seismic 12 May event was a small nuclear explosion.

William R. Lettis Selected as 2017 Joyner Lecturer


12 December 2016 - William R. Lettis has been selected as the William B. Joyner Memorial Lecturer for 2017. Lettis founded William Lettis & Associates, Inc. in 1990 and Lettis Consultants International, Inc. in 2011 to provide consultancy at the interface of earthquake science and earthquake engineering. He will deliver his lecture in April 2017 at the Seismological Society of America (SSA) Annual Meeting in Denver, Colorado and in March 2017 at the Earthquake Engineering Research Institute (EERI) Annual Meeting in Portland, Oregon.

Graduate Students Visit Congress as SSA Geo-CVD Grant Winners


4 November 2016 - Graduate students Rob Anthony, Kendra Johnson and Marshall Roger-Martinez were sponsored by SSA to attend Geosciences Congressional Visits Days (Geo-CVD) in September. The program brings science and engineering students to Washington, D.C. for two days to participate in a training session on the basics of how Congress works and how to impact science. Participants then visit Capitol Hill to discuss geoscience policy with Congressional staff and elected Members of Congress.
