First I am not indicating a Pending eruption, I am not a seizemologist by any means.
The Posted graphs indicate where the quake origionated and its length, Only a Profesional can determine rather or not this is Volcanic in Origion.. Again I am not a profesional, I am jsut posting this to aid you in where they origionated at. Not every squiggle is ground shake and not every ground shake is a quake. Seizomerters can register, glaciers moving, rock slides , and and the Obviouse Earth quake.
Again these are For refrence in where the quake occured. IT Does Not Mean an Eruption Will Happen..Only trained Geologist can forcast that. I am not trained in this area.
