A critical review of ground based observations of earthquake precursors

L Conti, P Picozza, A Sotgiu - Frontiers in Earth Science, 2021 - frontiersin.org
We aim at giving a short review of the seismo-associated phenomena detected on ground
that in recent years have been investigated as possible earthquake precursors. The paper …

Slow earthquakes, preseismic velocity changes, and the origin of slow frictional stick-slip

BM Kaproth, C Marone - Science, 2013 - science.org
Earthquakes normally occur as frictional stick-slip instabilities, resulting in catastrophic
failure and seismic rupture. Tectonic faults also fail in slow earthquakes with rupture …
