Brazil — Natural Disaster Report
South America · Live status: High (23 active events)
Current situation: 23 natural disaster events are currently monitored in Brazil, with a worst severity of Severe. Details, sources and timestamps are listed below.
Brazil's vast territory faces flooding, landslides and drought rather than earthquakes. The mountains behind Rio de Janeiro and São Paulo produce catastrophic landslides when intense rain saturates steep slopes covered in informal housing: the 2011 Serrana disaster killed over 900 people and the 2022 Petrópolis floods killed more than 230. The 2024 Rio Grande do Sul floods submerged Porto Alegre and displaced hundreds of thousands, the worst in the state's history. The Northeast suffers prolonged drought in the semi-arid sertão, while Amazon drought in recent years has cut rivers to record lows, stranding communities that depend on boats.

Disaster displacement in Brazil
398,728 internal displacements
Largest single event: 40,255 from storm, beginning 23 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 | 283,103 |
| Flood | 92,599 |
| Drought | 16,799 |
| Wildfire | 3,496 |
| Erosion | 1,764 |

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 →
What this site sees in Brazil
| Source | Events here, last 12 months | What it will not tell you |
|---|---|---|
| NASA FIRMS | 962 | 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. |
| WMO Alert Hub (national weather services) | 380 | 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. |
| GDACS (European Commission / United Nations) | 2 | 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. |
| US Geological Survey | none | Global for earthquakes above roughly M4.5, and denser where there are more seismometers. It publishes nothing about any other hazard. |
| European-Mediterranean Seismological Centre | none | Global for earthquakes, with the best coverage in Europe and the Mediterranean. It publishes nothing about any other hazard. |
| 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.
