The first image, taken on August 1 by the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA's Terra satellite, shows the Apple Fire as a large red blob in the Santa Cruz Mountains. The fire is surrounded by green vegetation, which indicates that the area has been recently burned.
The second image, taken on August 2 by the Visible Infrared Imaging Radiometer Suite (VIIRS) on NASA's Suomi NPP satellite, shows the Apple Fire as a brighter red blob. This indicates that the fire has been growing and intensifying. The VIIRS image also shows the smoke from the fire blowing eastward towards the Pacific Ocean.
The Apple Fire is one of several large wildfires that have burned in California this summer. These wildfires have caused extensive damage to homes and businesses, and have forced thousands of people to evacuate. The Apple Fire is currently 5% contained, and firefighters are working to extinguish it.
