(Seattle, WA) -- Seismologists say a cluster of small earthquakes off the southern Oregon coast and on Mount Rainier over the weekend were not big enough to trigger a seismic warning system that's set to debut this spring. Pacific Northwest Seismic Network manager Paul Bodin tells the Seattle Times that none of the quakes were "of particular concern." Bodin says the earthquakes were not significant enough to trigger the new ShakeAlert system, which is set to launch to the public in Oregon this March and in Washington this May. The largest quake over the weekend was a magnitude 5.1 about 175 miles off the coast of Bandon, Oregon.
