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.

Letter to SSA Members on Executive Order

31 January 2017 -- In response to the 27 January 2017 White House Executive Order to ban travel to the U.S. from selected countries, SSA President Jim Mori sent this letter today to the SSA membership.

Dear Colleagues:

The 27 January Executive Order signed by President Trump, curtailing immigration and entry to the U.S. from seven countries, has impacted the scientific community as a whole, including the Seismological Society of America (SSA).  We are aware of the hardship this travel ban places on our foreign-born colleagues and students. In some instances the order may prevent attending a conference or returning to work or study in the U.S. from a visit to one's home country. The need for free and unfettered exchange of knowledge and ideas is in the best interests of every nation. Scientific advancement is best achieved when there is cooperation and collaboration among scientists. Restrictions on admitting properly screened and vetted scientists are contrary to this objective.

SSA is committed to working in conjunction with other scientific organizations to address this issue. It will seek to advise the Administration on the need for a balance between ensuring the continued ability of the U.S. to attract and work with global scientific talent and protecting national security. We are following the issue closely and will continue to provide you updates, especially as they relate to SSA activities such as our Annual Meeting.

We encourage SSA members in the U.S. to contact their senators and representatives to share how this Executive Order will impact or is already impacting their work, and to urge them to support measures that allow and enhance global scientific openness and inquiry.


James Mori, President

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.

On the Cover…
The Mw 7.8 Ecuador earthquake of 16 April 2016 was the sixth earthquake larger than Mw 7 to rupture the subduction megathrust between the Nazca and South American plates since 1906. He et al., (this issue) used InSAR images to determine coseismic surface displacements associated with this earthquake. The 2016 earthquake is coincident with the location of the 1942 Mw 7.8 earthquake, and both likely ruptured an asperity that also failed in the 1906 Mw 8.8 earthquake. Shown here is the location and local detail of the megathrust. For this same 2016 event, Beauval et al. (this issue) compared observed ground-motion attenuation data with four different ground-motion prediction equations, evaluating the interface models used for seismic-hazard studies.
