A series of shallow earthquakes registered several hundred miles off the Oregon Coast on Wednesday morning, but quake experts say there鈥檚 no tsunami threat.
Don Blakeman, a geophysicist at the National Earthquake Information Center, explained the area off shore is a seismically active zone and clusters of quakes there are common.
鈥淚n this zone here, the plates are basically pulling apart or sliding past one another,鈥� he said. 鈥淪o you don鈥檛 get the vertical movement that would cause a tsunami.鈥�
The largest of the quakes was , and it happened just before 5 a.m. There were three smaller earthquakes before it and four after.
Blakeman said that鈥檚 probably not the end of the activity. Several more small quakes will likely register in the area throughout Wednesday.
But there鈥檚 no cause for alarm for communities along the coast.
鈥淭hese quakes are almost 300 miles off the coast, and that鈥檚 why they鈥檙e not really felt by people. It鈥檚 also why they鈥檙e not dangerous,鈥� he said. 鈥淭hey鈥檙e just too far away, basically.鈥�
