Large deep-focus shocks and significant volcanic eruptions in convergent plate boundaries during 1900–1980DIRECT SEEDINGSEED PRIMINGOCALA SAND PINEPINUS-CLAUSAData of large (M 7.0), subcrustal earthquakes (h 75 km), which occurred from 1900 to 1980, show that in at least seven subduction zones...

Deep-focus earthquakes that occur at 350–660 km are assumed to be caused by olivine → spinel phase transformation (PT). However, there are many existing puzzles: (a) What are the mechanisms for jump from geological 10−17 − 10−15 s−1to seismic 10 − 103...
the timing of Central Himalayan earthquakes. Introduction High relief of the Himalayan Mountains blocks the northward monsoonal winds from the Indian Ocean during June to September, resulting in intense precipitation on the southern slopes of the ranges1. This orography-controlled precipitation pattern, ...
Earthquake faulting at ~600 km depth remains puzzling. Here we present a new kinematic interpretation of two Mw7.6 earthquakes of November 24, 2015. In contrast to teleseismic analysis of this doublet, we use regional seismic data providing robust two
It has been proposed that intermediate- and deep-focus earthquakes occur on preexisting planes of weakness that were created at shallow depth. The purpose of this study is to test this hypothesis. We examined fault plane solutions for 360 events that occurred in the Tonga subduction zone from ...

During the triggering stage, earthquakes, volcanic explosions, undersea landslides, and meteorite impacts can trigger displacement of a large quantity of water either up or down, causing tsunami waves. During the tsunami stage, tsunami waves carry energy traveling through the water, but these waves ...
