Recent Earthquakes in Hawai`i
Credits...
Data sources
- Hawaiian Volcano Observatory seismographic network
- Automatic processing of seismographic data is a product of the USGS Earthworm
Seismic Software.
- Software used in manual processing of seismographic data and issuing earthquake
notifications at HVO is the Caltech-USGS Seismic Processing (CUSP)/
Information
on Seismic Activity in a Hurry (ISAIAH). CUSP is the product of a number of
seismologists and programmers based at USGS regional earthquake network
centers in Menlo Park and
Pasadena, California.
ISAIAH was added to CUSP in Pasadena to post earthquake information in
near-real time.
Programs and Maps
- The HVO implementation of the Recent Earthquakes in Hawai`i maps is
modeled after the Recent Earthquakes web pages designed and run for integrated
Northern and Southern California earthquake reporting. At HVO, Stuart
Koyanagi and Philip Ong installed and subsequently modified the
software
designed by Bob Simpson and colleagues at the
U.S. Geological Survey, Menlo Park.
Philip Ong further refined the HVO Recent Earthquakes system to incorporate
automated Earthworm data sources and Jim Luetgert's "eqwaves" waveforms, as
well as migrated the system to the current server.
- Maps are updated using the subroutine
library gd
written by Thomas Boutell, and the
gd interpreter tgd
written by Bradley K. Sherman.
- Waveform pages are generated using the Earthworm "eqwaves" module developed
and maintained by Jim Luetgert of the USGS Northern California Seismic Net.
- The earthquake location data, seismologist comments, and additional information (e.g., seismogram images) are distributed among various operators of the recenteqs software using a program called QDDS written by Stephen Jacob and Alan Jones.
