To scientists and others who use the
SuGAr data, please note:
The Sumatran GPS Array is being designed, constructed
and operated by members of the Tectonics Observatory at Caltech
and the Indonesian Institute of Sciences (LIPI). The SuGAr data
are processed and archived at SOPAC (Scripps Orbit and Permanent
Array Center). Funding for the SuGAr comes to the Tectonics Observatory
exclusively from the Gordon and Betty Moore Foundation.
The Observatory is pleased to make the SuGAr data
available to anyone who wishes to use them. However, if you use
these data in your published work, the Tectonics Observatory
requests that you acknowledge the scientists and technicians
of the Observatory, LIPI and SOPAC, who are establishing, maintaining
and operating the array.
This page will eventually also contain ArcGIS data used
to construct our map of the plate boundary and site maps and
basic data associated with our studies of the coral microatolls.
Western Sumatra
Seismic Network
Six short-period seismic stations were installed
in Sumatra in May 2005 in order to better determine the locations
of aftershocks of the Decmeber 26, 2004 and March 28, 2005 great
earthquakes in the Sunda Trench. Each site, co-located with GPS
stations of the SuGAr array, has an L4 1-Hz verticle seismometer
recorded by a Nanometrics Taurus 24-bit logger. The data are
continuously recorded on site and are retrieved every 3 to 5
months.
Preliminary analysis of the data is done using
the software program SEISAN, and initial results indicate a far
greater level of seismicity in the region than reported by the
NEIC and other agencies, especially in the area around Nyang
Nyang. more
