Great post. Scary..... After the birth of my daughter the first day i brought her home we experienced a 7.6 quake that lasted for about 80 seconds. Ever since then I have been trying to learn a little more about them. 3 hours north of me Nicaragua has had two over 6.0 in the past week and the country is now on red alert for a big one.(according to Costa Rican news)...After living through about 2000 replicas/aftershocks you begin to hear it coming before you feel it.... It is no fun but it is very interesting...
