Ecuador and Japan earthquakes: Are they related?

[CNN] It's way too early to tell, said Paul Caruso, a geophysicist with the U.S. Geological Survey.
"It's one day after the Ecuador earthquake and two days after the Japanese earthquake, so no real research has been done on these quakes as far as they're being connected," he said Sunday. 
"Usually we don't think earthquake are connected across the ocean," Caruso said, but there's ongoing research in "remote triggering," the idea that a big quake can cause another quake a long distance away.
The distance between Japan and Ecuador: 15,445 kilometers, or about 9,590 miles.
Both quakes occurred in this horseshoe-shaped area the National Geographic Society defines as "a string of volcanoes and sites of seismic activity, or earthquakes, around the edges of the Pacific Ocean."
It may seem more than coincidental that the quakes occurred a few days apart. But it's also true that the large majority of the world's earthquakes -- about 90% -- occur in the Ring of Fire, per the National Geographic Society. Read More
