6.4 magnitude near Tokyo, Japan is latest as of this watch. Concerning due to location, just along the arch of the sealine. Numerous earthquake swarms within last 24 hours along eastern Japan. 2 significant ones within the last hour, one in western Japan. Could be a prelude to another superquake, lets hope not though! California/Nevada border seeing increased seismic activity within last 24 hours as well, more so than usual. Alaska remains active as well. New Madrid area seeing slight activity. LISS shows activity across the board. Again a major event may be looming, worldwide activity is nearing frequency levels around the time of the 9.0 superquake in March. I have noticed that this year, on the 11th of each month, there has been heightened seismic activity, we all know about the number 11.
