Uplift slowing

1 Jun, 2009

The Yellowstone Volcano Observatory reports that uplift of the caldera floor is slowing.  Since mid-2004, the northeastern part of the caldera has risen some 9 inches (23 cm).  Scientists suspect that snow melt and groundwater recharge may be slowing down the rate of uplift, but they also say that, as in earlier episodes, the uplift might continue later in the year.
