This is not one you'll see in the news, but I still like it. First off, it is shallow, but with no fault mechanism, so we won't know if it is compressive. If it was compressive, it could be a super-quake like the Philippines. Second, it is in Taiwan, with excellent instrumentation, and these guys know the importance of PGV, unlike the thickies here in our neck of the woods.
As you can see, Taiwan is at a glorious plate intersection. They have the advantage that they'll never get a nearby M9, but that only matters for tsunamis. They can get super-quakes right under their cities, so that'll be the maximum PGV quake. I don't know if the place is being ripped apart or compressed. I think from the last big quake, it is probably being sheared.
Anyway, an M6.3 right in the mountains probably caused a few rockfalls. I do hope they had strong motion detectors right over the epicentre. Might be a new record for PGV.
