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.
More Than a Million New Earthquakes Spotted in Archival Data
By reanalyzing seismic records, researchers found a plethora of tiny earthquakes in Southern California that trace new fault structures and reveal how earthquakes are triggered.
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.
Secrets from the New Madrid Seismic Zone’s Quaking Past
High-resolution lidar topography reveals a long history of ancient earthquakes.
Precariously Balanced Rocks Reveal Earthquake History in Israel
Using the prevalence of unstable rock formations in Israel’s Negev Desert, researchers determined that historical earthquakes in the region were weaker than previously thought.
Imaging an Earthquake Rupture in High Definition
New field measurements using terrestrial laser scanning provide a detailed, centimeter-scale image of surface deformation patterns caused by the Magnitude 6.6 earthquake in Norcia, Italy.
How Do Main Shocks Affect Subsequent Earthquakes?
The results of a novel analysis of aftershock size distribution have important implications for more realistically assessing the seismic hazard of earthquake sequences.
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.
