Quaking

Note: this was sent originally as an email to family this morning, all of which were already aware of the earthquake. I forget to set my alarm properly, so the earthquake woke me up after seven this morning, as our house shook back and forth and our bed and doors and other things all made noises!

In case you are interested, I looked at the USGS (United States Geological Survey) this morning. (I'm sure some of you already have!)

As you can see from the key, the size of the circle shows the magnitude of the quake, and the colors show how recent. The blue means I clicked on it for more information, so the blue dot on the map is Magna's 5.7 magnitude earthquake:

Here are the USGS's significant events in the last 30 days:

This is all the activity for North America. I don't see any bright yellow, which indicates the activity shown is all within the last day. Alaska's biggest quake is 5.0. All the others are small, although Puerto Rico has had a whole lot of them today:

Earthquakes happen a lot. I don't usually think about them!
