Three recent earthquakes -- on Thursday and Saturday morning in Japan and Saturday night in Ecuador -- have gotten lots of attention because of the great destruction.
"Usually we don't think earthquakes are connected across the ocean," said Paul Caruso, a geophysicist with the U.S. Geological Survey, but there's ongoing research in "remote triggering," the idea that a big quake can cause another quake a long distance away.
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.
