Earlier today, two major earthquakes struck the Philippines. The first was a magnitude 7.4 earthquake and the second was a magnitude 6.7 earthquake. The earlier quake generated a minor tsunami, and caused severe damage to some structures. Yet, both of these earthquakes were peculiar for a simple reason; they occurred at unusually deep depths away from the tectonic subduction zone. Today’s video will discuss why these earthquakes happened through the opinion and analysis of a geologist.
