Journal ArticleDOI
Geodetic evidence for en echelon dike emplacement and concurrent slow slip during the June 2007 intrusion and eruption at Kīlauea volcano, Hawaii
E. K. Montgomery-Brown,D. K. Sinnett,Michael P. Poland,Paul Segall,Tim R. Orr,Howard A. Zebker,Asta Miklius +6 more
TL;DR: In this article, a joint nonlinear inversion of GPS, tilt, and InSAR data yields a deflationary source beneath the summit caldera and an ENE-striking uniform-opening dislocation with ∼2 m opening, a dip of ∼80° to the south, and extending from the surface to ∼2 km depth.
Journal ArticleDOI
The May 2005 eruption of Fernandina volcano, Galápagos: The first circumferential dike intrusion observed by GPS and InSAR
William W. Chadwick,Sigurjón Jónsson,Dennis Geist,Michael P. Poland,Daniel J. Johnson,Spencer Batt,Karen S. Harpp,Andrés G. Ruiz +7 more
TL;DR: In this article, the authors modeled the co-eruption deformation of Fernandina volcano, Galapagos, by including various combinations of planar dislocations to simulate the 2005 circumferential dike intrusion.
Journal ArticleDOI
The added value of time-variable microgravimetry to the understanding of how volcanoes work
TL;DR: Time-variable volcano gravimetry has shown great potential for imaging subsurface processes at active volcanoes, especially when combined with other methods (e.g., ground deformation, seismicity, and gas emissions) as discussed by the authors.
Journal ArticleDOI
Interferogram formation in the presence of complex and large deformation
TL;DR: In this article, a two-step algorithm is proposed to form intra-caldera interferograms from SAR image pairs spanning the 2005 Sierra Negra volcano eruption, where the first step involves a "rubber-sheeting" SAR image coregistration.
Journal ArticleDOI
Lava lake level as a gauge of magma reservoir pressure and eruptive hazard
TL;DR: The surface height of the summit lava lake in Halema'uma'u Crater fluctuates with surface deformation over short (hours to days) and long (weeks to months) time scales as mentioned in this paper.
