Advancing earthquake science worldwide
3 May 2017–Changes to the rate of wastewater injection in disposal wells may have contributed to conditions that led to last year’s Pawnee earthquake in Oklahoma, according to a new report published May 3 as part of a focus section in Seismological Research Letters.
1 May 2017– SRL has issued a call for papers for a Focus Section on Geophysical Networks and Related Developments in Latin America. In recent years, there have been many efforts throughout the region to improve and expand national seismic/geodetic networks; along with this, as part of larger projects, instruments to observe a variety of seismic/aseismic phenomena have been deployed.
20 April 2017–DENVER — Data collected from two tall buildings, one in Osaka and one in Los Angeles, demonstrate that long-lasting motions from distant earthquakes — up to hundreds of kilometers away — can shake those buildings severely and can cause structural and non-structural damage.
Mehmet Celebi of the U.S. Geological Survey discussed these two buildings at the 2017 SSA Annual Meeting. He suggested that design codes for these types of buildings should take into account these long-distance effects.
20 April 2017–DENVER — In May 2018, NASA Discovery’s InSight mission will be the first lander to place an ultrasensitive broadband seismometer on the surface of Mars — the first planetary seismometer deployed since the 1970s.
20 April 2017–DENVER — There is a 43% probability that the Wasatch Front region in Utah will experience at least one magnitude 6.75 or greater earthquake, and a 57% probability of at least one magnitude 6.0 earthquake, in the next 50 years, said researchers speaking at the 2017 SSA Annual Meeting. … Continue Reading »
20 April 2017–DENVER — As tensions rise again over the development of North Korea’s nuclear weapon and missile program, seismologists at the 2017 SSA Annual Meeting offered a unique glimpse at what the world knows about the location, depth and size of the country’s past nuclear tests.
