Array analysis of the seismic wavefield of long-period events and volcanic tremor at Arenal volcano, Costa Rica
(2014-06-06)
We use wavefield decomposition methods (time domain cross correlation and frequency domain multiple-signal classification) to analyze seismic data recorded by a dense, small-aperture array located 2 km West of Arenal ...
Thin-skinned mass-wasting responsible for widespread deformation at Arenal volcano
(Frontiers Media, 2014-12-03)
The shape and stability of a volcano’s edifice depends on the relationship between eruption rate and the loss or redistribution of material due to erosion, mass-wasting or deformation. This work provides measurements of ...
Integrated velocity field from ground and satellite geodetic techniques: application to Arenal volcano
(Universidad de Oxford, Reino Unido, 2015)
Measurements of ground deformation can be used to identify and interpret geophysical processes occurring at volcanoes. Most studies rely on a single geodetic technique, or fit a geophysical model to the results of multiple ...
Combined GPS, EDM and triangulation surveys of the rapid downslope motion of the western flank of Arenal Volcano, Costa Rica
(2011)
Here we present initial conclusions of a one year-long combined geodesy campaign on Arenal Volcano, in Costa Rica (2008-2009). Our data shows evidence for an active local tectonic surrounding, and a 7cm/yr displacement ...
Explosion mechanisms at Arenal volcano, Costa Rica: An interpretation from integration of seismic and Doppler radar data
(2012-01-21)
We execute an integrated analysis of broadband seismic and Doppler radar data to gain insights into the subsurface mechanisms that drive repetitive, mildly explosive activity of Arenal volcano (Costa Rica). We find large ...
Time-Dependent Spatial Amplitude Patterns of Harmonic Tremor at Arenal Volcano, Costa Rica: Seismic-Wave Interferences?
(2012-12-01)
Seismograms recorded at the receivers of a small‐aperture seismic array usually display very similar waveforms and amplitudes, as a consequence of their close proximity. During the analysis of the volcanic tremor wave field ...
