Just last week, I was reading reports that some geologists think the massive December 26th Indonesian quake that triggered the catastrophic tsunamis had not relieved the tension in that seismically active area but, counterintuitively, made a subsequent earthquake more likely. Now come reports of a ‘great’ quake, estimated at magnitude 8.5-8.7 on the Richter Scale, along the same fault. (CNN) What amazes me is that authorities are essentially guessing that there will be no appreciable tsunami from this quake because no one has reported one yet. That is the best we can do.
