Seismicity of the Archipelago: Preliminary Results

High Frequency Seismograms

Seismograms of local activity


     Examples of local events registered on the three components of station G06, and filtered highpass 1Hz. Left panel shows the mb 5.0 event, middle panel shows a shallow volcano-tectonic event beneath Alcedo Volcano, and the right panel shows a high frequency signal (3-7Hz), that may correspond to volcanic tremor. The appearance of the latter event on four of our seismometers indicates a location on nothern Isabela (Volcano Alcedo?).
