NCEDC archives continuous BDSN data for the 2002/11/03 Denali earthquake

March 25, 2004

The NCEDC has archived 2 days of continuous high frequency data from the BDSN network for the days surrounding the magnitude 7.8 Denali earthquake of November 3, 2002.

Instead of the normally triggered data at sample rates of 80 or 100 Hz, the NCEDC has archived continuous data from the HH and HL channels beginning on Nov 2 and continuing through Nov 3. This provides approximately 22 hours of data prior to the event and approximately 26 hours after the event. Two stations of the BDSN are not available in this special event archive - SAO and CMB.

The NCEDC is a joint project of the University of California, Berkeley and the USGS. Please send us email at ncedcinfo@ncedc.org or fill out our comments form if you have questions or comments about these changes.
