Ascent of magma through Earth's crust is normally associated with, among other effects,
ground deformation and gravity changes. Geodesy is thus a valuable tool for monitoring and …

Global Positioning System (GPS) instruments are routinely used today to measure crustal
deformation signals from tectonic plate motions, faulting, and glacial isostatic adjustment. In …

A key challenge for volcanological science and hazard management is that few of the
world's volcanoes are effectively monitored. Satellite imagery covers volcanoes globally …

In this chapter we discuss our InSAR observations of Aleutian volcanoes that have been
active during historical time, starting with Kiska Volcano in the west and ending with Mount …

Worst-case or high-end subduction-related earthquakes and tsunamis of 2004 and 2011 are
painfully fresh in our memories. High-end subduction-related volcanic eruptions have not …

A primary goal of volcanology is forecasting hazardous eruptive activity. Despite much
progress over the last century, however, volcanoes still erupt with no detected precursors …

Abstract We use 2007–2011 Advanced Land Observing Satellite (ALOS) data to perform an
arc‐wide interferometric synthetic aperture radar (InSAR) time series survey of the Trans …

Observations of volcanoes from space are a critical component of volcano monitoring, but
we lack quantitative integrated models to interpret them. The atmospheric sulfur yields of …

Satellite monitoring of volcanic activity typically includes four primary observations:(1)
deformation and surface change,(2) gas emissions,(3) thermal anomalies, and (4) ash …

Abstract The 2009 eruption of Redoubt Volcano, Alaska was particularly well monitored for
volcanic gas emissions. We report 35 airborne measurements of CO 2, SO 2, and H 2 S …
