Tearing an arc apart—insights from the northern Taupo Volcanic Zone

Researchers used seismic waves in the Bay of Plenty to create detailed images of the crust and mantle spanning the underwater northern section of the Taupo Volcanic Zone. By peering into the subsurface, they found evidence of a positive feedback relationship between magmatic intrusion and crustal extension.

Distant quakes trigger undersea landslides in Gulf of Mexico

Massive submarine landslides are often shaken loose if a large earthquake strikes nearby. However, triggers for smaller landslides are poorly understood. In a recent paper Dr. Wenyuan Fan and his colleagues, discovered 85 previously unknown submarine landslides in the Gulf of Mexico by analyzing 8 years of seismic data and extracting characteristic seismic signals of continental slope careening downhill.

Researchers Develop New Explanation for Destructive Earthquake Vibrations

Brown University researchers propose that rocks colliding inside a fault zone as an earthquake happens are the main generators of high-frequency vibrations.
