Analysis of High Rate GPS Data From the 2007 Mw 7.7 Tocopilla Earthquake in Northern Chile
Abstract
The CANTO (Central ANdean Tectonic Observatory) geodetic network captured the November 15 Tocopilla earthquake. Using GAMIT/TRACK software we compute 3-component 5Hz time series of station displacement to investigate coseismic and postseismic kinematics. We present spectral characteristics of the recorded coseismic waveforms and compare them to those of other earthquakes (southern Sumatra events). We determine arrival times and estimate simple source parameters from the high resolution records.
