This is a classic dipping slab earthquake, depth at 40 km.
You can see the strong subduction zone. That dips under Costa Rica, and makes for nice volcanoes.
This is a solution for fault motion. The earthquake rupture zone is quite small for this type of earthquake, and is in a good location to be a foreshock of an M8 or 9. 10% chance in the next 2 days. The earthquake is reporting some damage zones of Intensity 8 (VIII), so there are certainly some deaths and injuries.
Update: Looks like a very low PGV, not much damage.
