Multiple plates subducting beneath Colombia, as illuminated by seismicity and velocity from the joint inversion of seismic and gravity data
Subduction beneath the northernmost Andes in Colombia is complex. Based on seismicity
distributions, multiple segments of slab appear to be subducting, and arc volcanism ceases …

Subduction history of the Caribbean from upper-mantle seismic imaging and plate reconstruction
B Braszus, S Goes, R Allen, A Rietbrock… - Nature …, 2021 - nature.com
The margins of the Caribbean and associated hazards and resources have been shaped by
a poorly understood history of subduction. Using new data, we improve teleseismic P-wave …

Deep-focus earthquake analogs recorded at high pressure and temperature in the laboratory
Phase transformations of metastable olivine might trigger deep-focus earthquakes (400 to
700 kilometers) in cold subducting lithosphere. To explore the feasibility of this mechanism …

Seismic evidence for thermal runaway during intermediate‐depth earthquake rupture
Intermediate‐depth earthquakes occur at depths where temperatures and pressures exceed
those at which brittle failure is expected. There are two leading candidates for the physical …
