Earthquakes and Volcanoes Toolkit

Geological forces below the surface of the Earth have created some of our most inspiring landscapes—the Cascade Range, the Himalayas, Yellowstone, the Hawaiian Islands, the Galapagos Islands, and many more—but these same forces often also threaten our way of life and devastate communities.

NASA Earth observations help geologists and decision makers understand the movement of the Earth, monitor risk and vulnerability of populations, and assess impacts when an event does happen. This toolkit is designed to support research into earthquake and volcano-related disasters by providing easy access to relevant data and other resources

Earthdata Search is a data discovery and data access application that enables access to NASA Earth Observing System Data and Information System (EOSDIS) Earth science data distributed by EOSDIS Distributed Active Archive Centers (DAACs).

Socioeconomic Impacts From Hazards

Socioeconomic data help assess the exposure and vulnerability of a community to a disaster. Exposure is the presence of people, ecosystems, and infrastructure in places that could be adversely affected by a disaster. Vulnerability is the propensity to be adversely affected by a disaster.

Volcanic Aerosols

The dispersal of aerosols such as sulfur dioxide preceding and during a volcanic event can have not only an immediate but also a long-term effect on the atmosphere. Sulfur Dioxide (SO2) can create pollutants that aggravate respiratory conditions in humans. Depending on the scale of the event, It can also change global temperatures for a period of time.

Ground Displacement

There are several ways to measure movement of the ground due to an earthquake. The Global Navigation Satellite Systems (GNSS) is a network of satellites providing positioning and timing to ground receivers, which provide a fairly precise measure of any movement. Additionally, Interferometric synthetic aperture radar (InSAR) combines images from two different dates, one before the event and one after the event, to assess the amount of deformation from ground movement, whether from a fault rupture or a volcanic bulge, collapse, or lava flow.

Disaster Response

Many different types of NASA Earth observations can be used to provide disaster management personnel and first responders with relevant up-to-date data, often near real-time, to help in the management of recovery efforts.
