M6.9 earthquake Japan - Deep Slab

So, I'm an earthquake ghoul, always scanning the maps.  Tweetping is not showing this yet, so the earthquake maps win.

This is deep on the slab at 100 km.  It will still produce a high PGV on soft ground and mountainous areas.  Thus, we can expect landslides.

Update:  Looks like this earthquake had almost no PGV at surface, so it did nothing.  For an M6.9 that probably puts it at 400 km, much like the Bolivian big deep earthquakes.
