Improving our understanding of hazards posed by future large earthquakes on the Cascadia Subduction Zone requires advancements in the methods and sampling used to date and characterize past events.
Paleoseismology
Tiny Kinks Record Ancient Quakes
As Earth ruptures, micas kink. These kink bands hide in rocks millions of years old, preserving evidence of past quakes.
Was the AD 365 Mediterranean Earthquake Normal?
The great AD 365 earthquake at Crete has implied a locked Hellenic subduction zone that can produce more earthquakes to threaten Mediterranean coastlines. But what if wasn’t a subduction zone event?
Ancient Ruins Reveal 8th Century Earthquake in Sea of Galilee
Research into past seismic activity shows northeast Israel is still vulnerable to large quakes.
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.
Modeling Megathrust Zones
A recent paper in Review of Geophysics built a unifying model to predict the surface characteristics of large earthquakes.
Tsunami Records Show Increased Hazards for Chile’s Central Coast
Simulations of the historical quake raise new concerns: A similar event in the future could cause a devastating tsunami in Chile’s most populated coastal region.
Catching Glimpses of Centuries-Old Earthquakes
Researchers in the western United States survey the earthquakes that have torn up California for the past millennium.
Tracking Down Elusive Origins of Kazakhstan's 1889 Chilik Quake
New fieldwork and satellite data suggest that three faults may have caused a large earthquake near Almaty, Kazakhstan, more than a century ago.
Unknown Tsunami Trigger Hides Along a Creeping Aleutian Fault
A seismically quiet part of the Aleutian Subduction Zone may have caused tsunamis in the past—and may cause future tsunamis that could travel across the Pacific Ocean.
