ALASKA. YELLOWSTONE. CASCADES. HAWAII. USGS. The Big Picture. Many indigenous groups, including the Huni Kui, Ashaninka, and Madija, live in villages in the Brazilian rainforest near the border with Peru.

The Big Picture

Over the past three years, the Ashaninka and Madija say that they have seen more and more incursions on their territory from uncontacted tribes, defined by Survival International as groups who have no peaceful contact with mainstream society. The "Bravos," or "Braves," as uncontacted Indians are called in the region, carry out raids on other villages, putting the communities along the Envira River on permanent alert. Leaders of the Ashaninka tribe have asked the government and NGOs for help in controlling what they consider an encroachment on their area by these uncontacted indigenous groups, stating that the movement of these other tribes is the result of pressure caused by illegal logging across the border in Peru.

Michigan Tech's Volcanoes Page aims to provide information about volcanoes to the public and to complement other informational sites on the web. We started this site more than 20 years ago, when there were almost no other volcano sites--now there are lots, and many of them have far more resources. So we now aim to fill in spots that aren't covered elsewhere. Send your suggestions!
