A systematic search for tectonic tremor and low-frequency earthquakes in the Atacama segment of the Chilean subduction zone (24S-31S) turns up empty
Jannes Münchmeyer, William B. Frank, Sophie Giffard-Roisin +2
Subduction megathrusts release stress not only seismically through earthquakes, but also through creep and transient slow deformation, called slow slip events (SSEs). Understanding…

Characterising the Atacama segment of the Chile subduction margin (24°S-31°S) with >165,000 earthquakes
Jannes Münchmeyer, Diego Molina-Ormazabal, David Marsan +8
The Atacama segment in Northern Chile (24°S to 31°S) is a mature seismic gap with no major event (Mw>8) since 1922. In addition to regular seismicity, around the subducting Copia…

Seismic swarms unveil the mechanisms driving shallow slow slip dynamics in the Copiapó ridge, Northern Chile
Jannes Münchmeyer, Diego Molina, Mathilde Radiguet +6
Like earthquakes, slow slip events release elastic energy stored on faults. Yet, the mechanisms behind slow slip instability and its relationship with seismicity are debated. Here,…
