Big Under Ground Alteration Around the world

[Kojima]

In my previous blog,

Change of ground motion is accelerating globally in May, 2014

I showed some interesting ground motion found in the Rapid Earthquake Viewer (REV),

http://rev.seis.sc.edu/index.html

http://rev.seis.sc.edu/stations.html

where the seismogram showing a group of some characteristic large ground motion forms,

indicating big under ground alteration, was observed at some stations. So far, I have found out 15 stations showing it by searching in REV.

15) 2014/06/05: IU.PMSA; Palmer Station, Antarctica; 64.77 S, 64.05 W

The ground motion started with a big smooth wave at almost same time in a day, between 16:00 and 20:00, at every 15 station, indicating the earth wobble in a factor in this ground motion, and ended with a big jagged wave for some hours.

I show the seismogram of each station below.
