Experience during historical time throughout the Cascade arc and the lack of deep-seated deformation prior to the two most recent eruptions of Mount St. Helens might lead one to infer that Cascade volcanoes are generally quiescent and, specifically, show no signs of geodetic change until they are about to erupt. Several decades of geodetic data, however, tell a different story. Ground- and space-based deformation studies have identified surface displacements at five of the 13 major Cascade arc… 
Volcano Geodesy: Recent developments and future challenges
Abstract 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 hazards
Postglacial faulting near Crater Lake, Oregon, and its possible association with the Mazama caldera-forming eruption
Volcanoes of subduction-related magmatic arcs occur in a variety of crustal tectonic regimes, including where active faults indicate arc-normal extension. The Cascades arc volcano Mount Mazama
Space-Based Imaging Radar Studies of U.S. Volcanoes
The arrival of space-based imaging radar as a revolutionary land-surface mapping and monitoring tool little more than a quarter century ago enabled a spate of innovative volcano research worldwide.
Magma storage and diking revealed by GPS and InSAR geodesy at Pacaya volcano, Guatemala
GPS measurements from a campaign network at Pacaya volcano, Guatemala, occupied from 2009 to 2015 were combined with InSAR data from 2013 to 2014 to model deformation sources for two eruptive time
Time-Scales of Inter-Eruptive Volcano Uplift Signals: Three Sisters Volcanic Center, Oregon (United States)
A classical inflation-eruption-deflation cycle of a volcano is useful to conceptualize the time-evolving deformation of volcanic systems. Such a model predicts accelerated uplift during pre-eruptive
Quantifying Eruptive and Background Seismicity, Deformation, Degassing, and Thermal Emissions at Volcanoes in the United States During 1978–2020
Unlike most geohazards, volcanic eruptions are often preceded by warning signs, including increased seismicity, ground deformation, degassing, or thermal emissions from hours to months (or even
Synthesis of global satellite observations of magmatic and volcanic deformation: implications for volcano monitoring & the lateral extent of magmatic domains
Global Synthetic Aperture Radar (SAR) measurements made over the past decades provide insights into the lateral extent of magmatic domains, and capture volcanic process on scales useful for volcano
Volcanoes Along Convergent Plate Boundaries
This chapter focuses on the tectono-magmatic relationships along convergent plate boundaries characterized by subduction: these boundaries are the sites of the largest earthquakes and eruptions and
Regional Global Navigation Satellite System Networks for Crustal Deformation Monitoring
Regional networks of Global Navigation Satellite System (GNSS) stations cover seismically and volcanically active areas throughout the United States. Data from these networks have been used to

Intrusions of magma beneath volcanoes deform the surrounding rock and, if the intrusion is large enough, the overlying ground surface. Numerical models generally agree that, for most eruptions,

Abstract Tumescence at the Three Sisters volcanic center began sometime between summer 1996 and summer 1998 and was discovered in April 2001 using interferometric synthetic aperture radar (InSAR).
A satellite geodetic survey of large-scale deformation of volcanic centres in the central Andes
TLDR
A satellite-based interferometric synthetic aperture radar survey of the remote central Andes volcanic arc reveals the background level of activity of about 900 volcanoes, 50 of which have been classified as potentially active, and finds four centres of broad, roughly axisymmetric surface deformation.
