  abstract = {{T}he {T}ungurahua volcano, in {E}cuador, has been experiencing a substantial activity period since 1999, with several eruptions, including those of 2006 and 2008. {W}e use a persistent scatterers approach to analyze a time series of {E}nvisat synthetic aperture radar ({SAR}) data over the period 2003-2009, to investigate surface deformation in the region of the volcano. {W}e measure a continuous large-scale uplift with a maximum line of sight displacement rate of about 8 mm/yr, which is the first evidence of a sustained inflation in the {A}ndes for an active volcano encompassing several eruptions. {W}e model this signal as magma emplacement in a permanent storage zone at 11.5 km below sea level, with a net inflow rate of 7 million m(3)/yr. {T}he paroxysmal eruptions in 2006 and 2008 did not seem to disrupt this long-term signal. {H}owever, we observe significant deformation during the 2006 eruption consistent with an additional intrusion of 4.5 million m(3) of magma.},
