This is an amazing thread. Thank you to all that keep it updated.
I followed one of the links earlier and have just noticed there have been two 4.5 EQ in Chile today just a couple of hours apart.

Google maps has those two places at 1333km apart with Antofagasta being the most northerly point.
From Antofagasta to Valparaiso is 1333km south and from Valparaiso to Calbuco is 1194km south.
Could volcano activity be linked to those two EQ?
