Spooky seismic action at a distance: moderate earthquakes in western US cause submarine landslides in the Gulf of Mexico

This is such a cool study, and such an interesting result! Earthquakes triggering landslides is not a surprise, but surface waves from a magnitude 5.5 earthquake in the Gulf of California triggering a landslide in the Gulf of Mexico (1500 … Continue reading

Two reflections on the largest earthquake yet recorded, 60 years later.

It has been 60 years since a magnitude 9.5 earthquake struck the Chilean coast near Valdivia. The stats for this earthquake remain pretty mind-blowing even today. It is still the largest earthquake ever recorded – over 20% of the Earth’s seismic energy … Continue reading

At subduction zones, feeding a complicated plate means you get complicated earthquake behaviour out

What drives the occurrence of slow-slip events on subduction zones: “earthquakes”: that involve strain release over days and weeks rather than seconds? A new paper…doesn’t really answer that question, but it shows why it’s so complicated to answer.  The study uses … Continue reading

Earthquakes of 2018

Just as I did in 2016 and 2017, I thought I’d begin the new year with a look back at the earthquake activity in the last. According to the catalogue maintained by the USGS, the Earth’s ever-grinding tectonic plates produced … Continue reading

Earthquake prediction is a fool’s errand

If you want to make earthquake scientists jumpy, all you need to do is ask, "can you predict the next earthquake?" In fact, any variation on the theme of ‘earthquake’ and ‘prediction’ will do – unless it is one which … Continue reading
