Coastal desert, from Tumbes to Tacna
10% of Peru's hotspots
Few hotspots spread across the year: stubble burning in the valleys.

See how Peru's fire looks today.
Each glowing dot is a hotspot picked up by satellites this week. Everything is measured with the same yardstick since 2003, so you can compare and understand.
Explore Peru's fire02Three fire seasons
It burns, but not everywhere at once
The Coast, the Highlands and the Rainforest each have their own fire season. That is why we look at them one by one.
Highlands
Highlands, from Cajamarca to Puno
40% of Peru's hotspots
It rises in the dry season, from July to October, when pastures and fields are burned before the rains.
Rainforest
Rainforest: Loreto, Ucayali, San Martín and Madre de Dios
50% of Peru's hotspots
It peaks in August and September, when fields and felled forest are burned.
03The problem
Two satellites, two different pictures
NASA has watched Peru's fire with two cameras. They do not see or count the same way.
1
They see differently
MODIS sees the ground in 1 km squares. VIIRS, in 375 m squares. A small fire fits better in the second.

2
They count differently
Over the same land and years, VIIRS reports about 4.8 times more hotspots than MODIS.

We put them on one scale
We convert MODIS into VIIRS-equivalent hotspots, so twenty years can finally be compared.
