Assessment of station metadata in Alaska based on analysis of Love waves from the 2012-04-11 Mw 8.6 offshore Sumatra earthquake

Abstract

This report is part of a detailed investigation of a Mw 3.9 earthquake near Nenana, Alaska, that was triggered by Love waves from a Mw 8.6 offshore Sumatra earthquake. Results from that study appeared in Tape et al. (2013). We analyze all BH and HH channel waveforms that are available at the Alaska Earthquake Center. This report has three objectives: (1) to provide information that may help improve station metadata at Alaska stations; (2) to provide a snapshot of station performance in Alaska at one particular time (11-April-2012); (3) to provide details and figures on part of the waveform processing used in Tape et al. (2013).
