Uplift of a broad area centered ~6 km west of the summit of South Sister volcano started in September 1997 (onset estimated from model discussed in this paper) and was continuing when surveyed in August 2006. Surface displacements were measured whenever possible since August 1992 with satellite radar interferometry (InSAR), annually since August 2001 with GPS and leveling surveys, and with continuous GPS since May 2001. The average maximum displacement rate from InSAR decreased from 3–5 cm/yr… 
Time‐dependent changes in volcanic inflation rate near Three Sisters, Oregon, revealed by InSAR
[1] An extensive area near the Three Sisters volcanic center, Oregon, has been actively uplifting since 1996. In this study we use Interferometric Synthetic Aperture Radar (InSAR) to assess the Three
Decelerating uplift at Lazufre volcanic center, Central Andes, from A.D. 2010 to 2016, and implications for geodetic models
Interferometric synthetic aperture radar (InSAR) and GPS measurements beyond 2010 are presented for the first time for the Lazufre volcanic center in the Central Andes. Vertical uplift at Lazufre was
Source model for the Copahue volcano magma plumbing system constrained by InSAR surface deformation observations
Copahue volcano straddling the edge of the Agrio-Caviahue caldera along the Chile-Argentina border in the southern Andes has been in unrest since inflation began in late 2011. We constrain Copahue's
Dynamic deformation of Seguam Island, Alaska, 1992--2008, from multi-interferogram InSAR processing
Abstract We generated a time-series of ERS-1/2 and ENVISAT interferometric synthetic aperture radar (InSAR) images to study ground surface deformation at Seguam Island from 1992 to 2008. We used the

Constraining volcanic inflation at Three Sisters Volcanic Field in Oregon, USA, through microgravity and deformation modeling
[1] Microgravity data were collected between 2002 and 2009 at the Three Sisters Volcanic Complex, Oregon, to investigate the causes of an ongoing deformation event west of South Sister volcano. Three
Episodic inflation and complex surface deformation of Akutan volcano, Alaska revealed from GPS time-series
Abstract Akutan is one of the most active volcanoes in the Aleutian island arc. Studies involving seismic, GPS, and InSAR data have observed activity and deformation on the island since 1996. In this
A two-magma chamber model as a source of deformation at Grimsvötn Volcano, Iceland
Grimsvotn Volcano is the most active volcano in Iceland, and its last three eruptions were in 1998, 2004, and 2011. Here we analyze the displacement around Grimsvotn during these last three eruptive
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
The dynamics of large silicic systems from satellite remote sensing observations: the intriguing case of Domuyo volcano, Argentina
TLDR
It is found that deformation and warming are highly correlated, and depending on the sign and lag between the time series, either shallow sealing or magma influx could drive Domuyo’s ongoing inflation.
