Five small earthquakes struck Western Washington Friday morning including one registered as a negative magnitude.
The first was at 2:37 a.m. about 25 miles east of Eatonville. It had a magnitude of negative 0.3.
The second, a magnitude 2.6, was at 6:56 a.m. about five miles northwest of Kirkland. That was followed by a magnitude 1.5 quake at 7:25 a.m. about 10 miles north of Sedro-Woolley.
About 9 minutes later, a magnitude 2.3 earthquake struck south of Duvall and then there was a magnitude 1.2 quake at 7:43 a.m. about 20 miles north of Friday Harbor. That last quake was technically in Canadian waters near Vancouver Island.
There were no reports of damage or injuries.
