"Since October 2020, the Meteorology, Climatology, and Geophysics Agency (BMKG) had issued early warnings of potential extreme weather-related conditions due to various phenomena feared to coincide with the rainy season," BMKG Head Dwikorita Karnawati had stated recently.
The major disasters to strike in January 2021 were landslides in Sumedang, West Java, on January 9; a 6.2-magnitude earthquake in West Sulawesi on January 15; and massive flooding in South Kalimantan, starting January 12.
Torrential rains and unstable soil caused a series of landslides in Sumedang, claiming 19 lives, leaving 11 others missing, injuring 18 others, and displacing over one thousand local residents. Rescuers were also among the deceased.
In West Sulawesi, the earthquake that hit the districts of Mamuju and Majene on January 15, 2021, claimed at least 105 lives; displaced thousands of people; and destroyed homes, infrastructure, and public facilities.
