All Types of Large Earthquakes Produce Prompt Gravity Signals
New observations of recently discovered gravity perturbations that precede seismic waves have the potential to improve earthquake early-warning systems in California and other tectonic settings.
Reassessing California’s Overdue Earthquake Tab
Paleoseismic records show that the current 100-year hiatus since the last major event on the San Andreas, San Jacinto, and Hayward Faults is unprecedented in recent geologic history.
Examining Alaska’s Earthquakes on Land and Sea
The Alaska Amphibious Community Seismic Experiment is taking a close look at seismic activity along the Alaska Peninsula to understand earthquakes in this little-studied region.
Unused Fiber-Optic Cables Repurposed as Seismic Sensors
So-called dark fiber can serve as regional seismic activity monitors and also detect earthquakes thousands of kilometers away, according to new research.
Can Earthquakes Trigger Volcanic Eruptions?
A new study supports the idea that earthquakes may be associated with increased volcanic eruptions, but over longer time spans than prior research indicated.
Watch Tiny Cracks Travel in 3-D
Scientists used a transparent gel and high-speed photography to figure out how cracks form and spread. What they found could help explain earthquakes and fracturing glaciers.
Catching Oklahoma’s Tiny Tremors in the Act
Scientists map thousands of microearthquakes in Oklahoma to take a closer look at the seismic effects of wastewater injection following oil and gas operations.
Understanding Electrical Signals from Below Earth’s Surface
A new version of a free Web application (SIGMELTS 2.0) helps Earth scientists interpret electrical anomalies in Earth’s crust and mantle and track the sources of earthquakes and volcanic eruptions.
Lessons from Mexico’s Earthquake Early Warning System
The devastating 2017 Puebla quake provides an opportunity to assess how citizens perceive and use the Mexico City earthquake early warning system.
