Evacuation route during a disaster with health protocol in the new normal era

Abstract

The southern coast of Java Island, one of which is Sumbermanjing Wetan District, Malang Regency, is considered prone to the geological disaster tsunami. Sumbermanjing Wetan District is directly adjacent to the Indian Ocean, a seismic gap zone that produces geological processes and high-intensity seismic activity that can trigger tsunami waves. On June 13, 2021, the COVID-19 outbreak in Sumbermanjing Wetan District recorded 90 suspected cases (two were hospitalized and the other 88 were self-isolating at home), and 38 were confirmed positive for COVID-19 (34 recovered and 4 died). This research focuses on evacuation plans for coastal areas from the threat of a tsunami during the pandemic and the new normal era. The sub-variables for determining the shelters include building area, type of building, ease of access, building construction, and capacity. The sub-variables for determining the evacuation route include road class, pavement type, and road width. Meanwhile, the sub-variables for implementing health protocols in the new normal era are maintaining distance, wearing masks, washing hands, special treatment for symptomatic refugees, and implementing other health protocols. The implementation of health protocols in evacuation activities will bring an impact on the reduction of the available shelter's capacity. The study results indicate the need for additional new shelters to implement health protocols in the new normal era. With this addition, it will impact the travel time from the residential areas at risk of tsunami impacts to the shelters. One of the reasons is that the closest shelter to the residential area is already full of refugees, so the refugees have to move and evacuate to the other shelters that can still accommodate them.
