A New Spin Re:Possibly volcanic? (Score 1)

Someone posted that Drum seismometer reading and the spike shows up on a couple of the stations at the same time. You could be right. I recall seeing something about an undersea earthquake in the Sea of Japan, but I don't recall the date. That could be what I'm seeing on the F-Net link. However, the story keeps changing. Yonhap was at first saying the was no seismic activity, but is now saying that there was seismic spikes around 11pm Wednesday and 1am Thursday.
