Geophysicists from the Geological Survey of Brazil (SGB) initially assessed the risk of high-intensity earthquakes causing significant damage in Northern Brazil as low. While seismic activity is recorded, experts noted that major events are typically deep or distant, though residents in cities like Belém, Manaus, and Rio Branco might feel tremors from neighboring Colombia or Venezuela.

By late August, the situation in Northern Brazil evolved to include multiple environmental crises. In the state of Acre, the federal government declared a state of emergency in 21 municipalities due to severe drought affecting water supplies and river navigation. Simultaneously, a strong earthquake originating in Ayacucho, Peru—measured at a magnitude of 6.7 by the USGS and 7.2 by the Geophysical Institute of Peru—was felt in Acre, prompting the preventive evacuation of employees from the Legislative Assembly of Acre (Aleac) in Rio Branco.

In addition to seismic and drought concerns, a geological study by the SGB identified 87 areas in Rio Branco at risk of geological or hydrological disasters, potentially affecting 44,000 people. The study indicated that flooding from the Acre River accounts for nearly 60% of these identified risks.

### 2026-08-17: Seismic risk in Northern Brazil remains low, experts say

Geophysicists state that while seismic tremors from neighboring countries can be felt in Northern Brazil, the risk of high-intensity earthquakes causing major damage in the Amazon is low.
