Strong earthquake widely filmed in Chile

A swarm of magnitude ~5-6 earthquakes offshore Chile on April 23 was punctuated two days later by a much larger M6.9 earthquake yesterday evening. While nobody could have specifically predicted the size and timing of this earthquake, it is a terribly unsurprising event, occurring as it did in the midst of this swarm of heightened seismic activity, and in the highly seismically hazardous region of coastal Chile. As has been pointed out …

Chile keeps having earthquakes

…and keeps surviving them barely scathed. Chile has this year been rocked by its 3rd Great earthquake this century–its 14th if you include the last. Though the earthquake’s magnitude and the resulting Pacific-wide tsunami earned it headlines, it was a very mild earthquake in the global scheme of seismic impacts. This has a bit to do with the nature of offshore, subduction zone earthquakes, and a LOT to do with …

Monstrous earthquake in Chile… as it unfolds

The northern coast of Chile has been struck by a Great earthquake this evening, shaking the South America continent for hundreds of miles and thrusting a tsunami onshore and across the Pacific Ocean. Notably, this earthquake occurred in a well known seismic gap, the sole reach of South America’s Pacific coast subduction zone that did not rupture in the 20th (or 21st) century. In that sense, this was one of …
