Radar Altimetry as a Robust Tool for Monitoring the Active Lava Lake at Erebus Volcano, Antarctica

The First Second of Volcanic Eruptions from the Erebus Volcano Lava Lake, Antarctica—Energies, Pressures, Seismology, and Infrasound

Sulfur Degassing from Mt. Erebus Volcano, Antarctica

SO2 emission rates from Erebus volcano show periodicity, which directly relates to lava lake convection and magma and conduit processes. Mt. Erebus is a 3794 m stratovolcano with a persistently degassing convecting, phonolite lava lake. Lava lake SO2 emission rates were collected from 1992 to 2003 using the correlation spectrometer (COSPEC) and in 2003 and 2005 using a miniature ultra-violet di...

Spacecraft and In-situ Observations of the Mt. Erebus, Antarctica, Lava Lake: a Terrestrial Analogue for Pele on Io

Introduction: We have obtained multiple contemporaneous ground and space-based visible and hyperspectral infrared observations of a persistent active lava lake, one of the rarest volcanonological phenomenon. This unique dataset advances our understanding of remote sensing of lava lake activity on Earth and Io. The Mt. Erebus lava lake: Active lava lakes are the top of an open magma system and p...

Analysis of Active Lava Flows on Kilauea Volcano, Hawaii, Using SIR-C Radar Correlation Measurements

Precise eruption rates of active pahoehoe lava flows on Kilauea volcano, Hawaii, have been determined using spaceborne radar data acquired by the Space Shuttle Imaging Radar-C (SIR-C) . A coastal site downslope from the Pu'u O'o vent was imaged once per day, on each of the four days from October 7-10, 1994. Day-to-day decorrelation due to resurfacing was determined by interferometric combinatio...

Pulsatory andesite lava flow at Bagana Volcano

[1] Using a time series of TerraSAR-X spaceborne radar images we have measured the pulsatory motion of an andesite lava flow over a 14-month period at Bagana Volcano, Papua New Guinea. Between October 2010 and December 2011, lava flowed continuously down the western flank of the volcano forming a 3 km-long blocky lava flow with a channel, levees, overflows and branches. We captured four success...
