Within eight hours, three violent earthquakes struck geographically distant areas: northern California, where a 5.6 magnitude Richter scale tremor occurred on Wednesday, Japan, hit off the northern coast by a 7.2 magnitude quake, and Venezuela, with two subsequent tremors of 7.1

Strong earthquakes struck Japan and Venezuela, with the 7.1-magnitude Venezuela quake triggering a Caribbean tsunami warning, officials said.
