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.

BSSA: Early L.A. Earthquakes Possibly Triggered by Oil Production


1 November 2016 - Historical sleuthing has turned up evidence for a possible link between oil production and a handful of damaging earthquakes that took place in the Los Angeles Basin during its oil boom in the early 20th century, according to a new study published in the Bulletin of the Seismological Society of America (BSSA).

In particular, the 1920 Inglewood quake, the 1929 Whittier quake, the 1930 Santa Monica quake and the 1933 Long Beach earthquake may have been induced by oil production activities that took place prior to the time of the seismic events.

Japan, Taiwan, New Zealand Collaborate on Seismic Hazard Models

20 October 2016 - Since 2014, research groups in Japan, Taiwan and New Zealand have been collaborating on research topics and sharing expertise to help develop national seismic hazard models. In a focus section published October 19 in Seismological Research Letters, the scientists describe their work for the Joint Japan-Taiwan-New Zealand National Seismic Hazard Model Collaboration.
