Los primeros eventos de deslizamiento lento observados en el sur de Costa Rica

Rachel Fritts, Science Writer by Rachel Fritts 20 November 202320 November 2023

Cinco eventos observados en la Península de Osa revelan nueva información sobre el papel que estos pequeños y lentos terremotos pueden desempeñar en la acumulación de tensión y riesgos de tsunami a lo largo de las zonas de subducción.

A Strong Quake (or Two) Rattled Puget Sound 1,100 Years Ago

by Carolyn Wilke 27 October 202327 October 2023

Tree rings hint that two neighboring faults ruptured within 6 months of each other and suggest that the maximum magnitude of quakes around Puget Sound could exceed previous estimates.

Low-Frequency Quakes Have Modest Effect on Slow Earthquake Cycle

by Marcos Moreno 5 September 202331 August 2023

Slow slip phenomena on subdaily scales, captured by seismic and GNSS data, show that low-frequency earthquakes are incidental to larger magnitude slow earthquakes, in which aseismic slip dominates.

Talc May Make Mexico’s Subduction Zone More Slippery

Aaron Sidder, freelance science writer by Aaron Sidder 23 August 202323 August 2023

Production of the weak, water-bearing mineral at the interface between the Cocos and North American Plates could contribute to the occurrence of poorly understood episodic tremor and slow slip.
