On September 19, 2021 volcanic activity permanently altered the coastline of the small island of La Palma, located off the coast of northwestern Africa. As of November 24, 2021, the eruption has been active for over two months, with over 7,000 residents having been evacuated.

This image taken by the ECOSTRESS module aboard the International Space Station captured the lava flow on September 29, 2021, after the eruption. Dark spots along the coastline represent locations where lava flowed into the ocean, increasing the surface temperature.

ECOSTRESS's primary mission is to detect small changes in the temperature of plants to measure evapotranspiration rates. It can use the same instrumentation to detect changes in surface temperature associated with events such as volcanic eruptions. ECOSTRESS observations have a spatial resolution of about 70x70 meters, which enables researchers to study surface-temperature conditions down to the size of a football field. The mission can acquire images of the same region at different times of the day. This is advantageous when monitoring plant stress in the same area throughout the day, for example.

The ECOSTRESS mission launched to the space station on June 29, 2018. NASA's Jet Propulsion Laboratory, a division of Caltech in Pasadena, California, built and manages the mission for the Earth Science Division in the Science Mission Directorate at NASA Headquarters in Washington. ECOSTRESS is an Earth Venture Instrument mission; the program is managed by NASA's Earth System Science Pathfinder program at NASA's Langley Research Center in Hampton, Virginia.
