Another large quake and, perhaps, another volcano awakening?

Link to nearby San Pedro volcano info.

What leads you to believe the volcano will erupt?

How often does the area get quakes above 6? If often then what makes this one different enough to trigger off this volcano?

Please be more clear, the thread title is a bold question which means the thread needs some meat.

i think the title is pretty clear and it does pose a good question!

I'd like to see the idea presented not only in the title but in a lot more detail in the post.. Like I said there needs to be some meat to chew on.

There are not so often it is over 6 there.
Actually..

Here's an historic map.

There we go.
Thanks for the meat to chew on.

I doubt it's going to have any impact on the volcano as the quake was at a depth of 117km.

Thank you for adding those links! I'm not an earthquake expert, just seen this large earthquake had happened in Chile and went to check it if it was related to the Puyehue (sp?) volcano I had been hearing about here (and seen some pretty amazing pics of). But I found it to be near a different volcano...San Pedro (not to be confused with the San Pedro volcano in Guatemala).

Was hoping for some people with some expertise to weigh in.

look for back to back quakes of the same magnitude or similar 4.0-6.0 seems to be the norm before these volcanoes go off.

it is looking like there are swarms. then a larger quake or eruption following nearby.

look out before July 7. 10 days before things might pick up.
