Lower edge of locked Main Himalayan Thrust unzipped by the 2015 Gorkha earthquake

JP Avouac, L Meng, S Wei, T Wang, JP Ampuero - Nature Geoscience, 2015 - nature.com
Large earthquakes are thought to release strain on previously locked faults. However, the
details of how earthquakes are initiated, grow and terminate in relation to pre-seismically …

The precursory phase of large earthquakes

Q Bletery, JM Nocquet - Science, 2023 - science.org
The existence of an observable precursory phase of slip on the fault before large
earthquakes has been debated for decades. Although observations preceding several large …

Precursory slow slip and foreshocks on rough faults

C Cattania, P Segall - Journal of Geophysical Research: Solid …, 2021 - Wiley Online Library
Foreshocks are not uncommon prior to large earthquakes, but their physical mechanism
remains controversial. Two interpretations have been advanced:(1) foreshocks are driven by …

Months-long seismicity transients preceding the 2023 MW 7.8 Kahramanmaraş earthquake, Türkiye

G Kwiatek, P Martínez-Garzón, D Becker… - Nature …, 2023 - nature.com
Short term prediction of earthquake magnitude, time, and location is currently not possible.
In some cases, however, documented observations have been retrospectively considered …

Interseismic coupling, megathrust earthquakes and seismic swarms along the Chilean subduction zone (38–18 S)

M Metois, C Vigny, A Socquet - Pure and Applied Geophysics, 2016 - Springer
The recent expansion of dense GPS networks over plate boundaries allows for remarkably

Seismic and aseismic preparatory processes before large stick–slip failure

G Dresen, G Kwiatek, T Goebel, Y Ben-Zion - Pure and Applied …, 2020 - Springer
Natural earthquakes often have very few observable foreshocks which significantly
complicates tracking potential preparatory processes. To better characterize expected …
