The Amazon Basin sits on the ancient, stable Amazonian Craton, far from active plate boundaries.
Large earthquakes are rare. Minor, low-magnitude tremors occasionally occur, especially near the Andean foothills in the west.
There are no active volcanoes within the Amazon rainforest itself. Volcanism is concentrated along the Pacific Ring of Fire, far to the west.
The Amazonian Craton has remained largely intact for billions of years, providing a stable platform for the rainforest. Seismic hazards are minimal compared to plate-boundary regions.
Ongoing monitoring continues, but the current assessment indicates very low geological risk.
