New Animation!  “Japan: Overview of Earthquakes & Tectonics”

Japan has more measurable earthquakes than any other country and has over 100 active volcanoes. The tectonics are complicated, but in this animation we look at the basic mechanics of the region as we focus on two famous earthquakes: the 1995 Kobe earthquake and the 2011 Tohoku-Oki earthquake.

SCIENCE AND PROGRAM HIGHLIGHTS

Increased seismic instrumentation provides insight into the Rio Grande Rift

Increased seismic instrumentation provides insight into the Rio Grande Rift

New seismic stations help answer questions about the extent, deformation pattern and seismic activity of the Rio Grande Rift.
Earthquakes and volcanoes of the Galápagos Islands

Earthquakes and volcanoes of the Galápagos Islands

A temporary network of seismometers gives insight into earthquake activity and volcanic structure beneath the Galápagos Islands volcanoes.
Linking Faults in Napa Valley and Beyond

Linking Faults in Napa Valley and Beyond

Seismic data and gravity data suggest linkages between the West Napa Fault Zone and nearby faults, which has implications for the size of potential earthquakes along this system. Additionally, guided seismic wave amplification can cause concentrated regions of shaking and damage.
