Vertical deformation at GPS station WLWY during 2001-2018
Data from continuous GPS stations indicate how the ground is moving over time. Station WLWY, near White Lake on the Sour Creek resurgent dome in Yellowstone caldera, has been operating since 2001. This plot shows vertical ground motion recorded at the site. The area experienced subsidence during 2001-2004, uplift in 2004-2009, subsidence in 2009-2014, uplift during 2014-2015, and subsidence in 2015-2018. Quite the dynamic place!
