Monitor Mount Krakatau's Child Activities, BMKG Installs 6 Seismographs
Jurnal Utama. The Meteorology, Climatology and Geophysics Agency (BMKG) installed six seismographs around Mount Anak Krakatau. The six seismographs began operating Tuesday, December 25, 2018, namely three in the Banten and Lampung regions.
Head of the BMKG Earthquake and Tsunami Center Rahmat Triyono said that seismographs were installed to monitor the activities of Mount Anak Krakatau which were still significant and could potentially occur in landslides.
"Therefore, with this BMKG seismograph, by surrounding Mount Anak Krakatau, it is expected to be able to record. If one sensor records it after being arranged, he will issue an alarm," Rahmat said at a press conference at the BMKG office, Jakarta, Tuesday night, December 25 2018.
With the installation of these tools, Rahmat hopes, he will get accurate information from the activities of Mount Anak Krakatau. So that the BMKG can draw conclusions and decisions more quickly.
"If two at least three we can find out where the position is, the source of the vibration was. Especially if the six-six notes," he said.
Rahmat said, his party immediately gave a tsunami early warning if the seismograph recorded vibrations reaching 3.4 to 3.5 magnitude. After being felt safe until around one hour the early warning will be revoked.
However, said Rahmat, even though the BMKG will eventually issue a tsunami early warning, it is not certain that high waves will sweep over the land as happened on Saturday night, December 22, 2018.
"We hope that it will not cause new panic. It is better that we give a warning, thankfully there is no tsunami. If there is no sign of a tsunami, we convey that the tsunami warning was declared over," he said.
On the same occasion the Deputy of the Coordinating Ministry for Maritime Infrastructure Coordination, Ridwan Djamaluddin, stressed that earthquakes that ranged from 3.4 magnitude were not those which were the sole trigger of the tsunami in the Sunda Strait. Because there are other factors that need to be observed.
"We have the best hypothesis that is now the trigger for the tsunami, there is an avalanche of the slopes of Mount Anak Krakatau. So if he is 3.4 magnitude, if the landslide material is gone, there is no (tsunami)," said Ridwan.
Ridwan said from the analysis, the events of the Saturday tsunami occurred due to erosion of material eruption of Mount Anak Krakatau. Tsunami events were also triggered by other movements, such as tremors and extreme weather at that time.
"So don't hold it as if if there were 3.4 there would be a tsunami, I want to straighten it out," he said.
