3. This week in seismic news…
24 earthquakes of a magnitude of 4.0 or greater have occurred this week, with three of a 5.0 or greater.
The largest earthquake was a 6.3, occurring on February 10th, 40 km off-shore of Coquimbo, Chile. Shaking was reported to be felt as far as western Argentinia.
The majority occurred between the pinned locations on the right with shallow depths, continuing the trend discussed last week. This is thought to be due to high density rock protrusions located on the overriding plate, acting as speed bumps that amplify the damage in subduction.
