Diverse observations from the 2011 Mw 9.0 Tohoku-oki earthquake pointed to large coseismic fault slip proximal to the Japan Trench. This seismic failure prompted a reevaluation of the conventional view that the outer forearc is generally aseismic. However, the nature of near-trench fault slip during this event remains debated, without consensus on whether slip peaked at the trench or at greater...

The Colombia–Ecuador subduction zone is an exceptional natural laboratory to study the seismic cycle associated with large and great earthquakes. Since 1906 Mw = 8.6 earthquake, four > 7.5 megathrust earthquakes occurred within rupture area, releasing altogether a cumulative moment of ∼35% moment. We take advantage newly released catalogs global positioning system (GPS) data at scale bal...

The offshore Castor Underground Gas Storage (UGS) project had to be halted after gas injection triggered three M4 earthquakes, each larger than any ever induced by UGS. mechanisms that seismicity in the crystalline basement at 5–10 km depth 1.7 remain unknown. Here, we propose a combination of explain observed seismicity. First, critically stressed Amposta fault, bounding storage formation, cre...
