It is amazing to see how the earth works. We were able to "feel" the Haiti earthquake in January. Just like the Haiti quake, we could "feel" or measure this morning's Chile 8.8 magnitude earthquake.
Take a look at some of the helicorders from around the region. Time goes from top of the screen to the bottom.
First I want to show you a helicorder from a calm day two days ago.
Here are the helicorders from this morning across the region. The earthquake happened around 6:34 UTC.
