Don-could be that NE Nevada is far from a seismometer network and small aftershocks are not recorded. Also, your rates for uplift and subsidence are probably way too high-1"/yr=25 mm/yr, or 25 km in 1 million years. The White mountains may have been going up for 1 million years or several, but even after accounting for erosion I would bet that they have not come up 25 km. Same for the subsidence. Maybe it was 1 mm, not 1".
On the other hand, the resurgent dome at Long Valley may have gone up and down even faster than 1"/yr during the 1980s.....so maybe there could be some other short-lived motions around the caldera that are faster than can be sustained......Chris
