The earthquake was actually off the northern coast of Costa Rica, 87 miles west of their capital, San Jose. It was centered more than 282 miles deep. But you can see the close proximity between Carazo and Costa Rica! No wonder they felt it!
Tsunami warnings (meaning they are imminent) were in effect for the day. Michael was on higher ground - should I be reassured that he was on a side of a volcano? Anyway, the tsunami warnings were eventually dropped with no occurrence striking any of the Central American coastline.
That night, my friend Lisa called to see if I had heard from Michael. She reminded me of the the earthquake that hit Nicaragua in the 1990's - 116 people killed, 68 missing, and 1350 homeless. I had forgotten! Luckily, this one wasn't nearly as devastating.
