Abstract

Banda Arc is one of the vulnerable areas in Indonesia. It is trapped by the slab coming from AustralianEurasian Plate with the S ̶ N direction and the slab coming from Pacific Plate with the E ̶ W direction. Because of its location, it has a high seismicity, for example there was an earthquake that raised a big tsunami in 1852. On February 2nd, 2022, the newest earthquake with magnitude of 6.2 hit the Banda Arc. In many cases, earthquakes are damaging disasters, because their surface waves are shocking through anything they pass. Nowadays the surface wave is used to get the subsurface description and the variation of its velocity, and ambient noise tomography (ANT) is one way to solve it. By using some analyses like cross correlation and fast fourier transform (FFT) from the earthquake waveform three days before February 2nd, 2022, the depth and velocity group around the Banda Arc can be known. There is an indication that it was influenced by the ocean wave, which became wider and close to the main shock. Besides that, ANT result shows that the low velocity anomaly was distributed around the deepest area of the Banda Arc, because the energy absorbed more there, besides in the near location of hypocenter and resulting low velocity anomaly. It is shown that the low velocity anomaly can show how the geological condition is.

Abstract

Employees of the Center for Education and Training of Agency for Meteorology Climatology and Geophysics have two roles: one of Agency for Meteorology Climatology and Geophysics and the community in general who are expected to have adequate knowledge and skill to anticipate an earthquake. But, whether their knowledge and skill possessed are sufficient or not in dealing with the earthquake disaster. This research aims to identify an individual preparedness level for earthquake disasters in the Center for Education and Training of the Agency for Meteorology Climatology and Geophysics. The research was based on four parameters, namely 1) knowledge and attitude; 2) emergency planning; 3) warning system; and 4) resource mobilization capacity. The research which was started from February until April 2021 used the descriptive research method with the quantitative approach. The questionnaire used was the standardized questionnaire which had been developed dealing with the disaster preparedness concept by the Indonesian Institute of Sciences was collaborated with United Nations Educational and Scientific Cooperation and International Strategy for Disaster Reduction. Collecting data was conducted by distributing the questionnaire to 18 employees of the Center for Education and Training who as respondents in this research. Afterward, data which had collected was analyzed by using the tabulation frequency and cross-tabulation, diagram, as well as indexes. The results of this research were the majority of the individual preparedness level in “Sangat Siap” category (44.40 percent), whereas the majority of the preparedness level was based on four parameters had similar levels were in “Sangat Siap” category.
