SPOKANE — Another earthquake struck Spokane on Tuesday, although the magnitude 3.0 temblor didn’t prompt any damage reports.
The earthquake struck shortly after noon.
"My dogs went nuts. It was hard and strong," said resident Stacy Hollister.
Spokane was jolted awake Sunday morning by a magnitude 4.0 earthquake. No damage was reported in that 8 a.m. tremor.
Sunday’s shaker was the first to rattle the city since a series of small tremors on Sept. 28. More than 40 measurable earthquakes have been recorded since.
Scientists believe the earthquakes are occurring in ancient cracks in basalt rock beneath the city’s north side. They classify them as crustal earthquakes, probably triggered by compression of rock caused by larger global plate movements along the Pacific coast.
The quakes are thought to have no connection to the recent series of tremors near Mount St. Helens.
This fall, a group of seismologists held a public meeting in Spokane and said the city appears to be at risk of an earthquake as large as magnitude 5.0, which would be 10 times more powerful than Sunday’s quake.
