Abstract
Indonesia is a country that crosses the Ring of Fire or active mountain paths. The region is 40,000 km in size and shaped like a horseshoe. Moreover, the plate-meeting path contributes to Indonesia's high earthquake risk. According to the Meteorological Climatology and Geophysics Agency (BMKG), Indonesia is a meeting point for three tectonic plates: the Indo-Australian plate, the Eurasian plate, and the Pacific plate. This causes many earthquakes, tsunamis, and volcanic eruptions that often occur in Indonesia. A natural catastrophe is an extreme occurrence that causes casualties, environmental damage, property loss, and psychological effects. With the availability of a Geographical Information System (GIS), information such as tsunami or earthquake evacuation routes and disaster education may be transmitted visually. The government has created several android applications. The application contains information about earthquakes, climate maps, flash floods, volcanic eruptions, landslides, and tsunami waves. Info BMKG, inaRISK Personal, My Earthquake Alert, Newest Earthquake Info, BMKG Real-time Earthquakes, WRS-BMKG, and MAGMA Indonesia are some of the applications available. Because the public may be alerted of the probability of a disaster in advance, this application can assist in reducing casualties in the case of a disaster. Once this application is operational, it is intended to assist relevant organizations in disseminating community-required information more promptly, precisely, and properly.
