Subject: Earthworm Version 4.0

Earthworm Version 4.0 has been released.

You can download the release from our new ftp site:

ghtftp.cr.usgs.gov:pub/OUTGOING/earthworm/release_v4.0

v4.0 is the official Y2K compliant release of Earthworm. It was verified that all critical modules correctly function during the following time intervals:

 o Dec 31, 1999 - Jan 1, 2000
 o Feb 28, 2000 - Feb 29, 2000
 o Feb 29, 2000 - Mar 1, 2000
 o Dec 31, 2000 - Jan 1, 2001

Critical modules are all those modules which enable Earthworm to trigger on and locate an earthquake and save associated waveforms to disk.

Testing was performed under both Solaris and NT operating systems using trace data for two Northern California earthquakes (provided in run_test/data directory). The date stamps of this trace data was shifted to correspond to each testing period. In addition, the system clock on the computer was also set to the time in the future being tested.

IMPORTANT CHANGE- AFFECTS ALL MODULES

All installation ids and global message types are now defined in a file called earthworm_global.d (earthworm_inst.d has been expanded and renamed). The values defined in earthworm_global.d are critical to proper communication and data attribution among Earthworm systems around the globe.

A copy of earthworm_global.d must be placed in the EW_PARAMS directory (the official copy lives in the vX.X/environment directory).

DO NOT make any changes to this file. !!!! The contents of this file are under the control of Earthworm Central. Please direct any requested additions or changes to: Barbara Bogaert bogaert@…

NEW MODULES

waveman2disk

Not really a module, but a manual, interactive version of trig2disk. Its purpose is to manually request trace data from WaveServers? and save it to disk in various supported formats. It has two modes: triglist and interactive. In triglist mode, it reads a file containing one or more TYPE_TRIGLIST2K messages, then requests and writes out corresponding snippets of trace data. In the interactive mode, it prompts the user for the start time and duration of snippets, then gets that data from the WaveServers? and writes it out to disk. See the README in src/waveman2disk directory.

for more details.

EARTHWORM DOCUMENTATION

The Earthworm web site has been upgraded to be consistent with Version 4.0.

CONTRIBUTED SOFTWARE

Many Earthworm modules have been developed at regional networks to meet their specific needs. Since some of these may be useful to other networks, we make these available at the Earthworm ftp site in the Contributed_software directory. Currently, you will find modules developed at USGS Menlo Park, University of Memphis, University of Washington and University of Alaska, Fairbanks.
