No. The two quakes occurred about 9000 miles apart. That's far too distant for there to be any connection between them. Large earthquakes can and usually do lead to more quakes but only in the same region along or near the same fault. These are called aftershocks. Sometimes a large quake can be linked to a smaller quake that occurred earlier called a foreshock. In the case of the Japanese quake seismologists believe that several magnitude-6 quakes in the same region on the previous day were foreshocks to the Saturday event. But the two earthquakes are similar in some ways aren't they? Not really. The magnitude-7.8 quake in Ecuador was what would be considered a classic megathrust event a type that was first identified through the work of George Plafker a United States Geological Survey geologist on the great Alaskan earthquake of 1964. A megathrust quake occurs in the boundary zone where one of the planet's tectonic plates is sliding under another a process called subduction. Read More
