(NASA) – In the Amazon rainforest, fire season has arrived.

The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Aqua satellite captured these images of several fires burning in the states of Rondônia, Amazonas, Pará, and Mato Grosso on August 11 and August 13, 2019.

In the Amazon region, fires are rare for much of the year because wet weather prevents them from starting and spreading. However, in July and August, activity typically increases due to the arrival of the dry season. Many people use fire to maintain farmland and pastures or to clear land for other purposes. Typically, activity peaks in early September and mostly stops by November.

As of 16 August 2019, satellite observations indicated that total fire activity in the Amazon basin was slightly below average in comparison to the past 15 years. Though activity has been above average in Amazonas and to a lesser extent in Rondônia, it has been below average in Mato Grosso and Pará, according to the Global Fire Emissions Database.
