Monitoring system for Krakatau
Monitoring system for Krakatau
BANDUNG (JP): To develop a physical or mathematical model of a
volcanic system, scientists rely on monitoring systems to
continuously provide them integrated information.
Waluyo, a seismologist and volcanologist at the Physics
Department of the School of Mathematics and Physics of the Gadjah
Mada University, led geodynamic research in the Sunda Strait
under the Integrated Special Research program. He speaks about
some aspects of his research:
Q : How is your research conducted in the Sunda Strait?
A : We carry out this research in stages. The first stage is
telemetry hardware consisting of a multi-canal data-recording
system (data logger). This is important because the mountain is
far away and difficult to reach. Long distance measuring that can
be commanded from our base station in Carita is needed. We have
installed a permanent calibrated sensor at Anak Rakata as well as
in other locations which we deem right.
Q : What does the telemetry system measure?
A : The parameter measured is mainly seismic. Also, the
temperature parameters that can be used to study the heat flow
pattern. Our system can basically be divided into two main
systems: the measuring system that is installed at the location
of the sensor and the recording system at our base station in
Carita. Both systems are connected with each other through radio
communication. At present this equipment is able to measure and
record 16 data in 10 seconds. The intervals of measurement can be
set automatically through the base station.
Q : What is expected from the results of the research?
A : The earth research cannot promise something directly
applicable. However, from the data obtained, the knowledge of a
pattern or mechanism taking place in the center of the Earth can
be used as a reference to predict the danger of geological
threats. Thus, mitigation activities of disasters can be done. An
important thing is that with the existence of natural
laboratories like in Krakatau, Merapi or other locations in the
country, we hope that Indonesia will take a prominent place in
earth science. Applied earth science, such s looking for natural
resources, is not the objective of our research at Krakatau.
However, no less important is the opportunity for us to try out
our discoveries on hard terrain like a volcano. If it passes the
test on heavy terrain, such telemetry equipment can be used for
other purposes. I think Indonesia is lucky to have many natural
laboratories. In many western countries, they do not have similar
natural laboratories, so they actively conduct earth research in
Indonesia.
