SRL: Forgotten Archives Reveal Impact of 1918 Puerto Rico Earthquake and Tsunami
Repair petitions filed in the wake of the 1918 Puerto Rico earthquake and tsunami, stored and forgotten in the San Juan archives for nearly 100 years, are giving scientists a house-by-house look at the damage wrought by the magnitude 7.3 event. In Seismological Research Letters, Roland LaForge and William McCann describe how they used the records to trace the impact of the earthquake.
SSA, AGU Reaffirm Position Statement on the Comprehensive Nuclear-Test Ban Treaty
29 June 2017--Scientific research in Earth and space sciences advances our understanding of our world and contributes to strong global economies, security, and public health and safety. The American Geophysical Union (AGU) and Seismological Society of America (SSA) today announced a revision of their position statement, "The Capability to Monitor the Comprehensive Nuclear-Test-Ban Treaty (CTBT) Should be Expanded, Completed, and Sustained ."
BSSA: New Evidence for Past Large Earthquakes in the Eastern Tennessee Seismic Zone
27 June 2017-- The Eastern Tennessee Seismic Zone (ETSZ), a zone of small earthquakes stretching from northeastern Alabama to southwestern Virginia, may have generated earthquakes of magnitude 6 or greater within the last 25,000 years, according to a study published in the Bulletin of the Seismological Society of America.The ETSZ is the second-most active natural seismic zone in the central and eastern United States.
Call for Papers: SRL Focus Section on Non-explosive Active Source Monitoring and Imaging
30 May 2017 – Seismological Research Letters (SRL) announces a Focus Section on “Non-explosive active source monitoring and imaging.” This SRL section will focus on new developments of non-explosive active sources, data processing, subsurface imaging and monitoring with non-explosive active sources, and their contribution to the advancement in earthquake, tectonic/volcanic, and environmental sciences as well as their social impacts.

Fifty Years after the 1967 Koyna Earthquake: Progress in our understanding of Reservoir Triggered Seismicity (RTS)
Call for Papers: Deadline 1 December 2017 
4 May 2017--The Bulletin of the Seismological Society of America (BSSA) is soliciting papers for a Special Issue on Reservoir Triggered Seismicity. December 10, 2017 marks 50 years since the 1967 magnitude 6.3 Koyna earthquake in western India, recognized as the world’s largest Reservoir Triggered Seismic (RTS) event.
SRL: Wastewater Injection Rates May Have Been Key to Oklahoma’s Largest Earthquake
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.

The 3 September 2016 Mw 5.8 Pawnee earthquake, widely felt throughout Oklahoma and neighboring states, may be the largest injection-induced earthquake recorded to date. The cover figure depicts the slip distribution of the earthquake as derived from Grandin et al. (this issue), one of 10 original research papers presented here in an SRL focus section about the earthquake. The focus section provides a complete view of the stress evolution leading to the mainshock inferred from foreshock activities and coupled poro-elastic modeling; coseismic stress changes and deformations from both seismological and geodetic observations; dynamic hydrological responses at far-field; and liquefaction observations from geoelectrical and surface mapping.

The bottle shown here emerged shortly after the 18 October 1989 magnitude 7.1 Loma Prieta earthquake as earthwork was being done to repair liquefaction damage in San Francisco’s Marina District. Research reported by Hinzen et al. (this issue) indicates that it is an 8-ounce soda bottle from the Charles Belding Company, and several signs indicate that the bottle pre-dates the 1906 San Francisco earthquake. The location where the bottle was found suggests that it was among rubble from the 1906 earthquake used as artificial fill in the area before the 1914 Panama-Pacific International Exposition. This bottle probably survived two earthquakes 83 years apart.
