Monitoring system for Krakatau<\/p>\n
BANDUNG (JP): To develop a physical or mathematical model of a
\nvolcanic system, scientists rely on monitoring systems to
\ncontinuously provide them integrated information.<\/p>\n
Waluyo, a seismologist and volcanologist at the Physics
\nDepartment of the School of Mathematics and Physics of the Gadjah
\nMada University, led geodynamic research in the Sunda Strait
\nunder the Integrated Special Research program. He speaks about
\nsome aspects of his research:<\/p>\n
Q : How is your research conducted in the Sunda Strait?<\/p>\n
A : We carry out this research in stages. The first stage is
\ntelemetry hardware consisting of a multi-canal data-recording
\nsystem (data logger). This is important because the mountain is
\nfar away and difficult to reach. Long distance measuring that can
\nbe commanded from our base station in Carita is needed. We have
\ninstalled a permanent calibrated sensor at Anak Rakata as well as
\nin other locations which we deem right.<\/p>\n
Q : What does the telemetry system measure?<\/p>\n
A : The parameter measured is mainly seismic. Also, the
\ntemperature parameters that can be used to study the heat flow
\npattern. Our system can basically be divided into two main
\nsystems: the measuring system that is installed at the location
\nof the sensor and the recording system at our base station in
\nCarita. Both systems are connected with each other through radio
\ncommunication. At present this equipment is able to measure and
\nrecord 16 data in 10 seconds. The intervals of measurement can be
\nset automatically through the base station.<\/p>\n
Q : What is expected from the results of the research?<\/p>\n
A : The earth research cannot promise something directly
\napplicable. However, from the data obtained, the knowledge of a
\npattern or mechanism taking place in the center of the Earth can
\nbe used as a reference to predict the danger of geological
\nthreats. Thus, mitigation activities of disasters can be done. An
\nimportant thing is that with the existence of natural
\nlaboratories like in Krakatau, Merapi or other locations in the
\ncountry, we hope that Indonesia will take a prominent place in
\nearth science. Applied earth science, such s looking for natural
\nresources, is not the objective of our research at Krakatau.
\nHowever, no less important is the opportunity for us to try out
\nour discoveries on hard terrain like a volcano. If it passes the
\ntest on heavy terrain, such telemetry equipment can be used for
\nother purposes. I think Indonesia is lucky to have many natural
\nlaboratories. In many western countries, they do not have similar
\nnatural laboratories, so they actively conduct earth research in
\nIndonesia.<\/p>",
