Time series showing daily vertical GPS positions from the continuous GPS station HUSB between 2001 and 2022.
Emily Montgomery-Brown
As a research geophysicist focusing on volcano geodesy, I analyze ground- and satellite-based data to explore how magma moves underground, and discover other ways volcanoes deform.
Prior to joining the USGS, I was a visiting researcher at the Earthquake Research Institute at the University of Tokyo studying hydrothermal deformation at Miyake Jima volcano and an NSF post-doctoral fellow at the University of Wisconsin studying the seismic signals associated with flank sector failure at Kilauea volcano.

GPS time series from station HUSB, 2001-2022
Time series showing daily vertical GPS positions from the continuous GPS station HUSB between 2001 and 2022.
Deformation and seismicity near South Sister during 2001-2022
Comparison of vertical GPS motion measured at station HUSB (top) with earthquake depth (bottom). Red line is a 60-day average of the cleaned GPS time series plotted in gray. Earthquakes are plotted with respect to their magnitudes. The swarm in 2004 represents the vast majority of earthquake in the vicinity of the deforming region.
