How to Download Accelerogram for given Earthquake Event?

Following are steps for downloading acceleration time history for any earthquake record:

  1. Open http://service.iris.edu/irisws/timeseries/docs/1/builder/
  2. Check station info from http://ds.iris.edu/wilber3/find_event
  3. You can find more about parameters of timeseries inputs from find event page of wilber3
  4. Network = II, Station = AAK, Location = 00, Channel = BH1, Start time = 2015-10-26 09:11:18, End time = 2015-10-26 09:21:18, Correction = Perform Instrument Correction, Frequency Limits = 0.001-0.02-0.02-9. Check differentiate, taper = 0.1, taper window = cosine, output = plot
  5. The url link is generated below, press to open in new tab. A time history plot will be opened in new window, which, you can save as image.
  6. Change the output type to ASCII: 2 column format, and click the below link to download the data.
  7. You can also change to audio to hear calculated sound of earthquake.
  8. Change channel to BH2 and then BHZ to download other components.
  9. Open the text file in spread sheet to process data.
