Change of ground motion is accelerating globally in May, 2014

Watching heliplots on LISS (Live Internet Seismic Server) site, 

http://earthquake.usgs.gov/monitoring/operations/heliplots_gsn.php

we can see jolts occurring at some stations, VNDA, LBTB, LPAZ, PLCA, BOSA, CPUP and DBIC, weekly, 

Third a series of Jolt again! Now happening every 1 week.

Change of Jolt Appearance: Plate movement in progress

indicating the earth wobble in a factor in these plate jolts. 

In addition, LISS sometimes shows continuous undulation which means some continuous ground motion. The detail is not shown up on LISS, but can be seen on REV (The Rapid Earthquake Viewer) site.

The interesting ground motion, such as a big undulating motion or a continuous motion of some kind of undulation, is recently observed at some seismograph stations around the world.

It seems change of ground motion accelerating globally!
