Did the swarms in Indo happen before the big one, after or both??

Would be interesting to nail down pattern and get a better idea if the 8.2 was the beginning, or the end of something....


From what I remember the swarm started after the big one. There were several earthquakes before the big one, a matter of weeks before it. I dont remember their depths and though I did save at the time the charts showing last 30 days activity, I lost them when I formatted my PC. verysad

But the big one caused the whole thing to go haywire and it lasted for another 2 months or so, during which another big one occured, a magnitude 8. Somewhere in January 2005. Then it gradually slowed down by the half of February.

It would be nice if someone saved those charts, I think it would be shocking to see the number of earthquakes there.

For a little clarity, the Indonesian quake is a quite different fault line and fault type, one is a strike/slip and the Kuril area is a subduction fault, one of the reasons given for the constant depth readings is the subduction fault is in a horizontal plane. (do not rule out other possibilities)

This is the area of the fault from an aerial view

For an in depth (pun intended) synopsis of the preceding events on the same fault line go here.
