All regions of Indonesia experienced a major earthquake in 2023, except Kalimantan.

According to data from the Meteorology, Climatology, and Geophysics Agency (BMKG), 176 major earthquakes with a magnitude >5 struck Indonesia throughout 2023.

These major earthquakes most frequently occurred in Maluku (54 times), followed by Sulawesi (42 times), and Sumatra (23 times).

Earthquakes with a magnitude >5 also shook Java and Bali, with 20 occurrences each throughout 2023.

Nusa Tenggara experienced 12 such earthquakes, and Bali 5 during the same period.

Meanwhile, Kalimantan was the only island that did not experience any major earthquakes last year. This region also tends to be safer from moderate (Magnitude 4-5) and small-scale (Magnitude <4) earthquakes.

Throughout 2023, Kalimantan only experienced 6 moderate earthquakes and 12 small earthquakes.

Unlike other islands, which experience hundreds or thousands of moderate and small earthquakes annually, Kalimantan's frequency is significantly lower.

However, Kalimantan is not entirely free from natural disaster threats.

Based on data from the Indonesian Disaster Information Database (DIBI) of the National Disaster Management Agency (BNPB), at least 110 natural disasters occurred in Kalimantan throughout 2023, ranging from droughts, tornadoes, floods, landslides, to forest and land fires.

From January 1 to February 28, 2024, Kalimantan experienced 30 flood events. This resulted in hundreds of thousands of residents being displaced and damage to several public facilities.
