REV gives a seismograph of a ground motion at each station in the world,
and several types of ground motion can be seen.
Unusual ground motion is recorded frequently at several stations recently, indicating that the plate movement would be active more and more, and a situation of 7 of 10 progresses steadily towards the time when the scenario is completed.
A station COCO, West Island, Cocos (Keeling) Islands, in the Indian Ocean
is one of the stations showing such active ground motion.
It is thought that the ground motion of this place is related to the movement of Indo-Australian Plate
and bending of Sunda Plate including Indonesia sinking during 7 of 10 scenario.
I show a history of ground motion of COCO in REV here.
It showed a wave of the normal ground motion until May 21, 2013.
However, the wave became the clearly different patterns from June 9, 2013,
though the seismograph during the periods from May 20 to June 9 was unavailable. Therefore, it is thought that something which greatly changes the ground motion must have occurred within this period.The ground motion has fluctuated lively since June 9, 2013. [As of 2014/06/19]
