DESCRIPTION

The iatrigger program watches an orbserver for earthquakes of interest, usually identified by an Antelope automatic real-time processing system. For earthquakes that match the trigger criteria specified in the iatrigger parameter file, requests are made to the ia2orb(1) program to download Internet Accelerometer data from all stations configured for on-demand waveform download (for further details, see the man-page for ia2orb(1)).

EXAMPLE

Run iatrigger in verbose mode with hypocenter packets taken from the default orbserver and ia2orb acquisition commands also sent to the default orbserver:

% iatrigger -v -c : :

BUGS AND CAVEATS

The iatrigger program does not dynamically monitor its parameter file for changes. If the parameter file changes, iatrigger must be restarted for the changes to take effect. If more automation is necessary, the user may consider putting the name of iatrigger's parameter-file in the Pf_restart array of the rtexec.pf file for the real-time system under which iatrigger is running (for more details on that feature see the rtexec(1) man-page).
