A minor natural disaster that struck outside Seattle has reportedly been felt as far north as the Vancouver area.
Several smaller earthquakes have shaken the Monroe area since then. The second - measured at magnitude 3.5, occurred near Monroe a few minutes later.
The quake hit at about 2:52 a.m.
There were no immediate reports of damage or injuries.
The Northwest is especially prone to earthquakes.
The natural disaster initially registered as a 4.7 magnitude and was then downgraded to 4.4 before eventually going back up to a 4.6. The quake was followed by a 3.5 aftershock.
There isn't a connection between this natural disaster and the ones that rocked California earlier this month, Steele said.
