At 2:51 this morning we had an earthquake that that measured magnitude 4.6 and woke me up. I heard it before I felt it. My first thought was that something was rolling down the slope up the ridge and that it had hit the house. Midway through the 5-10 seconds or so, I figured it was an earthquake.
It’s been awhile since I felt one so it was pretty cool. A second quake hit at 2:53, a magnitude 3.5 quake. An exciting way to start the day!
I quickly checked the shake maps to see where it was. It was in the Three Lakes area, which of this is a fair distance north of here..
I filled out an “I felt it” report. I was hoping to be first, but I ended up being 7th.
Later, I heard on the radeio that a series of aftershocks have happened since the initial quake, and they were following the general fault zone that is connected to Seattle, so I checked it out on the map… the grouping is interesting, but the aftershoks have been relatively small.
Stuff like this is fascinating, though…
The local news was pointing out that a dam is situated near the quake area… There apparently was no damage.
The quake was felt as far north as Vancouver, BC, over to Wenatchee, and south of Olympia, a pretty sizable region.
” There was a cluster of about eight aftershocks following the two shake ups. There have been no major injuries or damages reported. “

The “Shake maps”, generated by the “I felt it” reports, showed a wide distribution:
At about 8:30, I rechecked the Seismogram… it was pretty interesting.
In all, it was a fairly exciting morning. =] The kids slept through it. they’re bummed.
