I've seen reports saying anywhere from 8.2 to 8.7. It occured about the same place as the Boxing Day Quake. Although it's not as large as the earlier quake that caused the tsunami, it's still a huge quake itself. It's over 10 times as powerful as the 1989 San Francisco Quake (7.1). There haven't been any tsunami, although now everyone knows to evacuate just in case. It was probably a horizontal slip instead of a vertical one. About 300 dead at this point. I can hardly imagine 300 dead, really. 300,000 is way beyond my comprehension. I'm sending my good thoughts that way.
