Characterizing the Fault Beneath the Marmara Sea
Researchers mine seismic wave data to elucidate the stress relief system of the Main Marmara Fault beneath Turkey's inland sea.
White House Showcases Earthquake Alerts, Federal Quake Readiness
A prototype ShakeAlert early warning system approaches alert-ready status as the administration issues an executive order on federal earthquake standards.
Alaska's Semidi Segment Could Unleash a Devastating Tsunami
Study reveals structures along the Alaskan convergent margin capable of generating a powerful tsunami directed toward the United States's West Coast.
Deep-Sea Microbes Can Leave Records of the Past
Researchers use carbon signatures within sea sediments to identify microbial activity and also to date earthquakes.
Plate Displacement Rate Offers Insight into 2011 Tohoku Quake
For the first time, scientists use GPS to measure the displacement rate of the subducting Pacific Plate near the source of disastrous shaking in 2011.
Subtle Seismic Movements May Help Forecast Large Earthquakes
Where a plate of Earth's crust slides under another and when frequent episodes of plate slippage occur without noticeable earthquakes, large temblors will more likely strike, a new study finds.
P Wave Amplitude Decay Offers a Glimpse of Earth's Structure
Scientists look at deep earthquake signals to map how seismic waves lose energy in the upper mantle across the United States.
Quake or Bomb? Seismic Waves Speak Truth, Even If Nations Don't
When the Earth rumbles and no one knows why, seismologists can analyze the seismic event's waveforms to determine whether a hidden explosion or an earthquake caused the shaking.
Oklahoma's Dormant Faults Hide Huge Seismic Risk Potential
Researchers look at induced seismicity data in Oklahoma to spot an increase of stress in faults that could cause even more damage than recent quakes.
