In May 2015, a severe glacier surge struck the eastern Pamir.
Imagery, like Landsat’s, offers an overhead view to NWS personnel.
A new collaborative platform has been developed to help Vietnam plan for and respond to flooding.
Developing the largest database of spatial extents for historic floods.
You can think of the Charter as a one-stop-shop for impact maps.
The Charter concept is this: a single phone number is made available to authorized parties providing 24/7 contact to a person who can activate the charter.
This month, three Landsat scenes were ingested by the USGS Hazard Data Distribution System to provide data for Charter activations.
This month, one Landsat scene was ingested by the USGS Hazard Data Distribution System to provide data for Charter activations.
These maps, provided to responders for free, often show where the damage is and where crisis victims are, allowing responders to plan and execute relief support.

Analyzing a three-decade record of vegetation cover change from the Landsat to compare previous controls on Sierra Nevada forest growth rates and effects of recent fluctuations in water availability since the mid-1980s.
NASA and the U.S. Geological Survey’s Landsat satellite images over the past three decades showed that the severe drought periods recorded since the 1980s have not slowed rapid tree and shrub growth, especially on steep slopes burned recently by wildfires.
The Charter concept is this: a single phone number is made available to authorized parties providing 24/7 contact to a person who can activate the charter. Once activated, a project manager takes charge.
On April 27, 2011, a severe weather outbreak occurred across the southeastern United States, resulting in 199 tornadoes across the region and over 300 fatalities.
On December 23, 2015, an unusual early winter season tornado outbreak struck much of the Tennessee Valley.
The Charter concept is this: a single phone number is made available to authorized parties providing 24/7 contact to a person who can activate the charter.
This month, 126 Landsat scenes were ingested by the USGS Hazard Data Distribution System to provide data for Charter activations.
The Charter as a one-stop-shop for impact maps—an essential resource, since in many cases satellite data are the only practical method to assess current ground conditions after a disaster.
Naga Manohar Velpuri, works with the USGS Famine Early Warning Systems Network (FEWS NET). The project has recently initiated a large-scale project to monitor surface water bodies in the pastoral regions of Africa using multi-source satellite data and hydrologic modeling techniques. Currently, a total of 293 water points are being monitored in 10 countries. Velpuri shared some of the projects findings he presented at #AGU15.
Justin Roberts-Pierel from the Joint Center for Earth Systems Technology, uses Landsat 8 to detect landslides in the Himalayas. He provided information about his studies at #AGU15. We talked with him about his work.
Alex Riter, a graduate student at the University of Maryland College Park, presented her finding on how Hurricane Sandy affected New Jersey coastal marches at #AGU15. We talked to Riter about her research.
At #AGU15 Yurika Kato, a Geosciences graduate student at the University of Missouri-Kansas City, presented his research about how the 2010 Haitian earthquake and resulting human migration affected landslide occurrences in the Port-au-Prince province. We spoke with Kato about his research.
William Kochtitzky, a student from Dickinson College, presented a poster on glacial changes on Peru’s Nevado Coropuna volcano at #AGU15.
The Charter concept is this: a single phone number is made available to authorized parties providing 24/7 contact to a person who can activate the charter. Once activated, a project manager takes charge. The project manager knows what satellite resources are available, how to task them to collect data, and how to quickly analyze the collected data to create impact maps for first responders. These maps, provided to responders for free, often show where the damage is and where crisis victims are, allowing responders to plan and execute relief support.

This month, 166 Landsat scenes were ingested by the USGS Hazard Data Distribution System to provide data for Charter activations.
For those who live along its shores, Lake Tanganyika in east Africa is the backbone of local transportation and serves as an essential source of household water and protein. Every night, fishers lure nocturnal, sardine-like fish called dagaa with compression lamps that are strung between their boats. From the shore, the lake sparkles with the lights of miniature moons as people gather the treasured catch.
Landsat 8 imagery is being used to identify increased wildfire susceptibility due to the invasion of cheatgrass on rangelands.

As millions of people regroup from earthquakes in Nepal, a team of international volunteers is combing through satellite imagery of the region to identify additional hazards: earthquake-induced landslides. “Landslides are a common secondary hazard triggered by earthquakes or rainfall,” said Dalia Kirschbaum, a remote sensing scientist at NASA’s Goddard Space Flight Center and a leader of a landslide mapping effort. “Because landslides can mobilize and move so quickly, they often cause more damage than people realize.”

The Chongsecun landslide was found by a Canadian government scientist (Ministry of Forests, Lands and Natural Resource Operations Canada) scrutinizing post- and pre-quake Landsat 8 images.
