A powerful magnitude 7.1 earthquake shook the earth only 18 km east of the small town of 10,000, Tirua, located within Arauco Province in Chile.
The earthquake shook 17 km directly beneath a hilly region dotted with farms, although surely impacting Tirua, and other nearby towns Puren, Traiguen, Temuco, and Padre Las Casas. As this was a “shallow” earthquake, it likely produced lots of shaking on the surface compared to deeper quakes.
Of high interest is the location of today’s earthquake, which is only 40 km from the location of the largest earthquake of 2010, a magnitude 8.8 that shook the world during 27-Feb-2010.
Not only that, but just yesterday, a magnitude 7.0 shook Argentina, just 1,600 km to the northeast. Two magnitude 7 earthquakes back-to-back within 24 hours, is not something that happens very often.
The annual 100 year average is just 15 magnitude-7 earthquakes, while we’ve already received 2 during just the second day of the year.
The region is located on the edge of the Nazca tectonic plate, which itself is pressed against the Pacific plate, the ring of fire. Numerous volcanoes dot the boundary up and down the South American coast of Chile and Argentina.
Stay tuned and check back at MSB for updates as more data becomes available.
