USGS:  A 6.5 magnitude earthquake hit Antofagasta, Chile on Monday, 6/20/11, at 16:36:01 UTC, at a depth of 127.1 km (79 mi).  There are no reports of injuries at this time.  

My Comments:  Mark 13:8 "Nation will rise against nation, kingdom against kingdom, and there will be earthquakes in various places, there will be famines and troubles; these are the beginnings of sorrows."  Major earthquakes (> 6.99 mag) are occurring at an alarming frequency:  
1863 - 1900 = 12

1901 - 1938 = 53
1939 - 1976 = 71
 1977 - 3/11/11 = 164
