A M6.0 quake 20 minutes ago 180 km NE of Guadalupe Island (Caribbean).

No focal mechanism yet. In position where is should at least be associated with the subduction zone there. Normally I don't post on M6 subduction quakes outside of the USA, but there have not been a lot of these the last few years on that plate boundary, and we have been commenting on subduction foreshocks. Experts for other recent subduction quakes have said the chances of a quake being followed by a larger one are something like 5% to 10%.

It was an oblique normal faulting earthquake:

So logically less directly related to the subduction motion and so, also logically (I don't have any data) less likely to be a foreshock for a subduction earthquake.
