Indonesia — Natural Disaster Report
Asia · Live status: High (243 active events)
Current situation: 243 natural disaster events are currently monitored in Indonesia, with a worst severity of Severe. Details, sources and timestamps are listed below.
Indonesia lies along the most active section of the Pacific Ring of Fire, where the Indo-Australian plate subducts beneath the Eurasian plate. It has more active volcanoes than any other country, and its subduction zones generate the largest earthquakes on Earth. The 2004 Sumatra-Andaman earthquake produced the deadliest tsunami in recorded history, killing over 220,000 people across fourteen countries with Aceh worst affected. The 2018 Palu earthquake showed a further hazard: soil liquefaction, which swallowed entire neighbourhoods. Volcanic history here shaped the global climate — the 1815 Tambora eruption caused the "Year Without a Summer" worldwide, and Krakatoa in 1883 generated tsunamis over 30 metres high. Seasonal monsoon rain causes severe flooding and landslides across Java, while dry-season fires on peatland in Sumatra and Kalimantan create regional haze crises.

Risk profile
Earthquakes and tsunamis year-round along the Sunda Trench. Volcanic activity continuous, with dozens of volcanoes under regular monitoring. Monsoon flooding and landslides October-April, heaviest on Java. Peatland fires and haze during the dry season, roughly June-October.

Dry season fires
— June to October
Peatland and forest fires in Sumatra and Kalimantan, and the haze that follows them.
Seasons describe when a hazard is historically most likely, averaged over many years. They are not a forecast and say nothing about this week.
Hazard seasons
| Season | Months | Notes |
|---|---|---|
| Wet season | November to March | Flooding and landslides, heaviest on Java. This season crosses the new year. |
| Dry season fires · now | June to October | Peatland and forest fires in Sumatra and Kalimantan, and the haze that follows them. |
Disaster displacement in Indonesia
1.5 million internal displacements
Largest single event: 1.1 million from storm, beginning 25 November 2025.
A displacement is a movement, not a person: somebody forced from home more than once in a year is counted more than once. These are movements caused by disasters only — displacement caused by conflict is counted separately and is not included here.
| Hazard | Displacements in 2025 |
|---|---|
| Storm | 1,130,312 |
| Flood | 283,847 |
| Volcanic activity | 16,190 |
| Mass Movement | 12,193 |
| Earthquake | 7,558 |
| Year | Displacements |
|---|---|
| 2025 | 1,450,100 |
| 2024 | 516,237 |

River flood forecast — Indonesia
No chance of exceeding even its 2-year flood flow in this forecast.
GloFAS alert level: Inactive · Peak expected: in 11-14 days (on 2026-11-01) · forecast of 19 Oct 2026
GloFAS forecasts are computer model output, published for information only. They are not a flood warning: only national and regional authorities issue flood warnings for their own area. A reporting point is a place on the model's river network, which may sit a few kilometres from the town it is named after. All 259 rivers →
Emergency numbers — Indonesia

112 — Emergency call centre
A national programme, but NOT available everywhere. Komdigi reported more than 70 cities and regencies had implemented it as of 2024, out of roughly 514. If it does not connect where you are, use the local police, fire or ambulance number.
Last checked 4 September 2026. Numbers change and some are provincial rather than national. If one does not connect, use the authorities listed above.
What this site sees in Indonesia
BMKG issues weather, earthquake and tsunami warnings for Indonesia, and PVMBG sets volcanic alert levels. This site ingests neither. Much of what appears here for wildfires is NASA FIRMS, which reports satellite thermal anomalies rather than confirmed fires - on peatland especially, a hot pixel is an observation and nothing more.
| Source | Events here, last 12 months | What it will not tell you |
|---|---|---|
| WMO Alert Hub (national weather services) | 2,504 | Each warning comes from one country own alerting authority, so the scale is that agency scale and is not comparable between countries. Many agencies publish no coordinates, and those warnings are placed at the centre of the country rather than where the weather is - the area name is the real answer. |
| NASA FIRMS | 1,657 | Global, but it sees only what the satellite saw on its pass, and thick cloud hides fire. A quiet day here is not evidence that nothing burned. |
| European-Mediterranean Seismological Centre | 603 | Global for earthquakes, with the best coverage in Europe and the Mediterranean. It publishes nothing about any other hazard. |
| US Geological Survey | 69 | Global for earthquakes above roughly M4.5, and denser where there are more seismometers. It publishes nothing about any other hazard. |
| GDACS (European Commission / United Nations) | 8 | Global, but deliberately selective: it alerts on disasters likely to need INTERNATIONAL response. Serious local flooding that a national agency handles alone will not appear here. |
| ReliefWeb (UN OCHA) | 1 | Global, but it reports on humanitarian RESPONSE. It arrives days after an event rather than during it, and never functions as a warning. |
| NASA EONET | none | Global and curated rather than automatic, so it is slower than the raw feeds and carries far fewer events. |
| MeteoAlarm (EUMETNET) | none | Europe only. It publishes no coordinates at all, so every warning here is placed at the centre of its country and the area name is the only reliable indication of where it applies. |
| NOAA Tsunami Warning Centers | none | These two centres warn for the US and Canadian coasts and for the Pacific and Caribbean basins. The Indian Ocean and Mediterranean have their own warning centres, which are not read here. Their routine information statements - the ones that say there is NO tsunami danger - are deliberately not imported, so an empty tsunami list means no threat was issued, not that nothing was checked. |
| NOAA National Hurricane Center | none | The Atlantic and the eastern and central Pacific only. No typhoon in the western Pacific and no cyclone in the Indian Ocean or the southern hemisphere appears here; those come from GDACS and from national services. |
Not applicable here: US National Weather Service — Covers the United States only. It publishes nothing about any other country, so its absence from a country page is not an outage. ; USGS Volcano Hazards Program — United States volcanoes only - Alaska, Hawaii, the Cascades, Yellowstone, California and the Northern Mariana Islands. It says nothing about Indonesia, Iceland, Italy or anywhere else, so its silence about a foreign eruption is not a judgement about that eruption.
