“…Pranantyo et al [2] pointed out that, in the Flores region, there had been a tsunami phenomenon in the preinstrumental period (in 1815, 1818, 1820, and 1836) and the period after the 1992 pre-instrumental with Mw 7.8. This phenomenon relates to Flore's back arc thrust tectonic activity [2], [13].…”

“…People in the eastern half of Flores Island and the surrounding islands can feel the earthquake. In addition to an earthquake with a large magnitude, this earthquake caused a tsunami with inundation reaching a distance of 30 m to the west, a depth of 20.4 km, and a run-up measured at Ilepadung -East Flores of 11 m, Babi Island, Sikka District 5.5 m, and Wuring -Sikka 2.4 m [13]. The next earthquake occurred on December 14, 2021, in Flores with a strike-slip mechanism causing a new fault [19].…”

“…Okal [10] explains that the 1992 Flores earthquake and tsunami were caused by an underwater landslide and resulted in an extreme run-up as high as 26 m. Pranantyo and Cummins [11] added that this phenomenon causes a change in ground level with a lift of 1.1 m and a drop of -1.6 m. The results of field observations explained that after the tsunami occurred, there were no traces of buildings found on Babi Island, Flores [12], and the destruction of most of the north coast of Flores. This phenomenon also caused 500 people to go missing [13]. Other findings revealed that the damage caused by tsunami waves came from two directions with different magnitudes and deposited sand on the North and South coast [14].…”

This study aimed to analyze seismic data, which is then made into an infographic to map the level of tsunami hazard in the Sikka District. The research was carried out in Sikka District, East Nusa Tenggara, located between 121°55'40''-122°41'30'' east longitude and 08°22'-08°50' south latitude. The data source comes from the IRIS Earthquake Browser, and the analysis stage was carried out in two phases. The first analysis used seismic data analysis, and EQ Energy used IRIS (Incorporated Research Institutions for Seismology) data. Meanwhile, the second analysis maps the tsunami risk by determining the tsunami hazard in areas with the potential for a tsunami. Based on the analysis of seismicity data showed that Sikka District has the potential for an earthquake accompanied by a tsunami. In contrast, the results of the EQ Energy analysis caused by the December 14, 2021 earthquake were known as the value of Ehf = 6.46 × 1014 J and EBB = 5.48 × 1015 J. The analysis of the level of tsunami susceptibility based on the tsunami run-up height in Sikka District showed that the northern coastal area of Flores had various potentials, where the highest vulnerability level was in the Alok subdistrict and parts of Talibura. Meanwhile, the area with the lowest potential was the Kewapante subdistrict.

The Flores Sea has experienced devastating earthquakes with magnitudes >7 over the past 30 decades. It can trigger a tsunami and provide important theoretical, experimental, and field information. The seismicity study stated that the island of Flores had experienced tsunamis during the pre-instrumental period (1815, 1818, 1820, and 1836) and the pre-instrumental period in 1992. This study discusses the development of tsunami research in Flores using a literature review approach. The data source comes from the Scopus database, with data analysis using VOSviewer. The search results obtained a total of 22 documents, with the result that the 1992 Flores earthquake became the main research topic and the beginning of the era of modern tsunami science.

“…Due to the Flores back-arc thrust fault presence, the Flores Island in East Nusa Tenggara exhibits strong tectonic activity (Handayani, 2020;Maneno et al, 2019). Due to this activity, Flores was struck by an earthquake and tsunami in 1992, which found in 1952 fatalities and 500 unaccounted-for deaths (Julius & Daryono, 2021).…”

Flores Island is vulnerable towards natural disasters. Therefore, it requires an effective disaster warning ma-nagement. In this context, schools play an important role in disaster warning system. However, not all schools implement Disaster Risk Reduction (DRR) procedures effectively. Therefore, efforts are needed to improve disaster warning system among schools by integrating the three pillar principles, which include safe facilities, effective disaster management, and resilience education. This study aims to understand the state of school readiness in the Flores region and assess the extent to which these schools apply the three pillar criteria for school disaster warning system. The research method used is a qualitative descriptive ap-proach, with data collection through an open questionnaire distributed using Google Forms. The result showed that the locations of the respondent's schools are spread across the most disaster-prone areas of Flo-res, especially along the coastal areas. In addition, there are still many schools in the region that have diffe-rent levels of understanding and awareness regarding to disaster warning system. Based on that issue, the program for activating the disaster warning system in school area is very important to apply and can increase public awareness of disaster warning system. To achieve that idea, a collaboration between school commit-tees, external parties, and the Flores community is essential to strengthen the school infrastructure and to build an effective response towards potential disaster risks and threats.
