SEATTLE -- A moderate earthquake hit off the coast of Vancouver Island early Thursday morning.
The earthquake had a preliminary magnitude of 4.1. The quake epicenter was about 183 miles west of Vancouver, British Columbia, and 143 miles northwest of Neah Bay.
This is close to the location of a 6.4 earthquake last Friday. There were no reports of damage or injuries.
Meanwhile, three big earthquakes shook three countries overnight, all of them happening within a minute of each other.
The biggest was a magnitude 6.2 earthquake off Japan's northeastern coast. The second was a magnitude 6.0 earthquake off New Zealand's north island.
A magnitude 5.1 earthquake also hit off the coast of Cuba at 4:43 a.m. local time, about 25 miles off the coast and 375 miles southeast of Cuba's capital Havana.
USGS geophysicist Randy Baldwin said earthquakes are common in that area of the sea near Cuba; no tsunami warnings have been issued.
