Strong Motion Data from the 2012 M7.8 Haida Gwaii Earthquake

During the October 28 2012 moment magnitude (Mw) 7.8 earthquake offshore Haida Gwaii, British Columbia, the Geological Survey of Canada had three Internet Accelerograph (IA) stations that recorded the strong ground motions resulting from this event. These data have been used in a number of publications since 2013. Three-component, instrument calibrated, unfiltered numerical acceleration data for the three stations PRP01 (Prince Rupert), MSS01 (Masset) and QCC01 (Daajing Giids) are now easily accessible in miniseed and ascii formats.

Details of IA are available here: https://www.earthquakescanada.nrcan.gc.ca/stndon/CNSN-RNSC/sm/IA_Details-en.php

Description: Title: Data merge and calibration factor applied -- Description: 3-component, raw accelerograph data is extracted as miniseed files in 5 minute increments. For this event 2 files containing 5-minute increment files each, totalling 10 minutes of data was extracted for each station. Each station has a specific calibration factor associated with it to convert from counts to g. This was calibration factor was also applied.

For the data in ascii format a simple OBSpy routine miniseedtoascii was used to convert the data.
