More than 80,000 fires have erupted since the start of 2019 — an 83 percent increase on last year and the highest since records began in 2013.
The latest fires have now been ravaging the Amazon for three weeks, triggering anti-government protests and international anger.
The dramatic NASA photos show the increase in smoke and fire activity as flames break out in Rondonia, Mato Grosso and Amazonas.
More than half of the fires are in the massive Amazon Basin, home to 20 million people.
An estimated 1,663 new fires were started between Thursday and Friday, according to Brazil’s National Institute for Space Research.
Environmental organisations and researchers believe most of the Amazon fires were likely started by humans who want to clear the land for commercial gain.
