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.

Spatiotemporal evolution of dike opening and décollement slip at Kīlauea Volcano, Hawai'i Spatiotemporal evolution of dike opening and décollement slip at Kīlauea Volcano, Hawai'i
Rapid changes in ground tilt and GPS positions on Kīlauea Volcano, Hawai'i, are interpreted as resulting from a shallow, two‐segment dike intrusion into the east rift zone that began at 1217 UTC (0217 HST) on 17 June 2007 and lasted almost 3 days. As a result of the intrusion, a very small volume of basalt (about 1500 m3) erupted on 19 June. Northward tilt at a coastal tiltmeter...

Geodetic evidence for en echelon dike emplacement and concurrent slow slip during the June 2007 intrusion and eruption at Kilauea volcano, Hawaii Geodetic evidence for en echelon dike emplacement and concurrent slow slip during the June 2007 intrusion and eruption at Kilauea volcano, Hawaii
A series of complex events at Kīlauea Volcano, Hawaii, 17 June to 19 June 2007, began with an intrusion in the upper east rift zone (ERZ) and culminated with a small eruption (1500 m3). Surface deformation due to the intrusion was recorded in unprecedented detail by Global Positioning System (GPS) and tilt networks as well as interferometric synthetic aperture radar (InSAR) data acquired...

Slow slip event at Kilauea Volcano Slow slip event at Kilauea Volcano
Early in the morning of 1 February 2010 (UTC; early afternoon 31 January 2010 local time), continuous Global Positioning System (GPS) and tilt instruments detected a slow slip event (SSE) on the south flank of Kilauea volcano, Hawaii. The SSE lasted at least 36 hours and resulted in a maximum of about 3 centimeters of seaward displacement. About 10 hours after the start of the slip, a...

Kilauea slow slip events: Identification, source inversions, and relation to seismicity Kilauea slow slip events: Identification, source inversions, and relation to seismicity
Several slow slip events beneath the south flank of Kilauea Volcano, Hawaii, have been inferred from transient displacements in daily GPS positions. To search for smaller events that may be close to the noise level in the GPS time series, we compare displacement fields on Kilauea's south flank with displacement patterns in previously identified slow slip events. Matching displacement...
