Early Monday morning, the Oregon coast experienced a series of earthquakes. The largest was a magnitude 5.8 earthquake at 12:52 a.m. Earthquakes measuring 4.3 and 5.5 following over the next three hours, with a last 4.4 quake hitting at 7:46 a.m.
The tremblors were not strong enough to trigger tsunamis. Geologists say these earthquakes happen with some regularity, sometimes multiple times a year. They are not a sign that a Cascadia faultline earthquake is any more probable.
