High winds propelled a wildfire through parts of Valparaiso, Chile, on April 13, 2014. It quickly became the largest fire in the history of this port city. The fire started in a forested area on April 12 and eventually reached wooden homes built on steep hills around the city. According to news reports, at least 12 people died, 2,000 homes were destroyed, and about 10,000 people evacuated as the fire moved through a section of the historic city.
The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite acquired this image of the fire at 11:10 am local time (14:10 UTC) on April 13. Fire detections are outlined in red in the forest south of the city, which is pale gray. A long plume of smoke stretches northwest over the Pacific Ocean, a clear indication that winds were strong and blowing the flames toward the city.
Valparaiso is the third largest city in Chile, with a population of more than 280,000 people. It was established in 1536 and developed into an important international seaport in the 19th century. The city is a UNESCO World Heritage site.

NASA Celebrates Earth Day with Public Events, Online Activities :
NASA will celebrate the 44th anniversary of Earth Day with a variety of live and online activities April 21-27 to engage the public in the agency’s mission to better understand and protect our home planet.
This year, for the first time in more than a decade, five NASA Earth Science missions will be launched into space in the same year. These new missions will help address some of the critical challenges facing our planet today and in the future: climate change, sea level rise, access to freshwater resources, and extreme weather events. For more information about NASA's Earth science activities in 2014, visit:
Earth Day in the Nation’s Capital
