Earthworm Program:
seisan_report Overview

(last revised April 23, 2015)

The seisan_report program watches an Earthworm ring for TYPE_HYP2000ARC type messages indicating that the mega-module ("sausage") has located an event, and generates seisan s-files using parameters extracted from the messages. The program waits long enough to allow trig2disk to have written a wavefile, which allows the wavefile name to be included in the s-file when it is written out.

The program also watches for TYPE_MAGNITUDE messages from localmag. Parameters from these messages will be added to the appropriate s-file (which should not yet have been written at that point).

The program can be configured to write a TYPE_EVENT_ALARM message to the ring for alarm modules to pick up. This only happens upon receipt of a TYPE_MAGNITUDE message, so if locmag isn't running then no alarms will be sent.

The original program was contributed by David Scott and Richard Luckette of the BGS (based on menlo_report). It has been modified to handle S arrivals from Earthwom and to have better WAV file matching.
