Use the form below to
search and select a custom
earthquake catalog from the
master catalog of the Pacific Northwest Seismograph Network. Only ten years of
data can be searched and extracted at a time.
If you want more than ten
years' data you must make multiple requests.
There is a help page available to explain
details of the catalog and format issues.
This form is based on the NCSNDC catalog search at UC Berkeley.
Thanks to Doug Neuhauser.
