Abstract

We explore the application of terrestrial radar interferometry (TRI) as a tool for imaging changes in topography associated with the December 1, 2015 – ongoing eruption of Momotombo, Nicaragua. The eruption sequence included a 2 km long channelized lava flow from a summit crater in its early stages that transitionined to intermittent strombolian-vulcanian explosions. Two TRI campaigns were undertaken in December 2015 and April 2016. Changes in flow channel morphology and the destruction of a dome within the summit crater between December and April were apparent in the data. Potential small-scale deformation along a geothermal zone on the southern flank of the volcano may also be present. TRI is particularly well suited to monitor this edifice due to the long range of the instrument, up to 16km.
