Brazil Earthquakes Today: Live Tracker

About Earthquake Activity in Brazil

Brazil has low seismicity, but occasional intraplate earthquakes occur, especially in the northeast. The 1955 M6.2 earthquake in the Serra do Tombador was the largest ever recorded in Brazil. Major faults include Transbrasiliano Lineament, Samambaia Fault. Notable quakes include 1955 Serra do Tombador (M6.2), 2020 Acre (M6.5, deep). The seismic risk is low. Tectonically, Brazil lies on intraplate – stable craton. This page provides real‑time USGS data and historical context for Brazil.

The region is defined by Transbrasiliano Lineament, Samambaia Fault, and the risk level is classified as Low. With a population of 214 million, understanding local seismic hazards is crucial.

Why does Brazil experience earthquakes?

Brazil lies on Intraplate – stable craton. The movement of these plates builds up stress, which is released as earthquakes. In subduction zones, one plate dives beneath another, generating some of the largest quakes on Earth. In some regions, strike‑slip faults produce frequent moderate earthquakes.

❓ Is Brazil on a fault line?

Yes. Brazil is crossed by Transbrasiliano Lineament, Samambaia Fault, making it prone to seismic activity. The seismic risk level is classified as Low.

❓ What should I do during an earthquake in Brazil?

Drop, cover, and hold on. Stay away from windows, and if outdoors, move to an open area. After the shaking stops, check for injuries and be ready for aftershocks. Prepare an emergency kit with water, food, first aid, and a flashlight.
