All data that we gather must be processed and sent to IRIS’s database in Washington, according to their formatting requirements.
Once we have done that we use IRIS’s Seismiquery tool to generate a WEED file. This tool returns a file of seismic events based on parameters we define such as location, magnitude strength & type, time period, etc. We use this file to generate markers in our data so we can filter out events not associated with the Neal area.
WEED Files from 01/05/2012 – 02/16/2012:
- All global events of mag >= 5
- 51N, 33S, -106E, -128W, events of mag >= 3
- 48N, 42S, -111E, -120W, events of mag >= 1
