ARIA

Overview

ARIA is a collaboration between JPL and Caltech to exploit radar and optical remote sensing, GPS, and seismic observations for hazard science and response.  

ARIA investigates the processes and impacts of earthquakes, volcanoes, landslides, fires, subsurface fluid movement and other natural hazards by applying modern geodesy, merged with ground-based observations, to improve society's resilience.  ARIA develops state-of-the-art ground deformation measurements, change detection methods and physical models using GPS and synthetic aperture radar observations, automating the required large scale processing, and producing basic data products for the science community.

ARIA Damage Proxy Map of Southern Florida from Hurricane Irma
The Advanced Rapid Imaging and Analysis (ARIA) team at NASA's Jet Propulsion Laboratory in Pasadena, California, created this Damage Proxy Map (DPM) depicting areas of Southwestern Florida, including Key West and Naples, that are likely damaged as a result of Hurricane Irma (Category 4 at landfall in Florida), shown by red and yellow pixels. The map is derived from synthetic aperture radar (SAR) images from the European Space Agency's (ESA)...

Flood extent map created by the ARIA team at NASA-JPL/Caltech, derived from the ALOS-2 ScanSAR data acquired 8/27/17 (~1:30PM Central Time) over Texas including Houston.
The above image is a screenshot of the flood extent map created by the ARIA team at NASA-JPL/Caltech, derived from the ALOS-2 ScanSAR data acquired on 8/27/17 (~1:30PM Central Time) over Texas including Houston. This Flood Proxy Map (FPM) covers an area of 350-by-350 km and is derived from Japan Aerospace Exploration Agency's (JAXA's) ALOS-2 PALSAR-2 pre- (2017-07-30) and post-event (2017-08-27) Synthetic Aperture Radar (SAR) amplitude images. The pixels in light...

Radar image of Amatrice Italy Earthquake
NASA and its partners are contributing observations and expertise to the ongoing response to the Aug. 23, 2016, magnitude 6.2 Amatrice earthquake in central Italy caused widespread building damage to several towns throughout the region. This earthquake was the strongest in that area since the 2009 earthquake that destroyed the city of L'Aquila. Scientists with the Advanced Rapid Imaging and Analysis project (ARIA), a collaboration between NASA's Jet Propulsion Laboratory, Pasadena,...

NASA Aids Response to Nepal Quake
NASA and its partners are gathering the best available science and information on the April 25, 2015, magnitude 7.8 earthquake in Nepal, referred to as the Gorkha earthquake, to assist in relief and humanitarian operations. Organizations using these NASA data products and analyses include the U.S. Geological Survey, United States Agency for International Development (USAID)/Office of U.S. Foreign Disaster Assistance, World Bank, American Red Cross, and the United Nations Children's Fund. NASA and its collaborators are pulling optical and radar satellite data from international and domestic...

The perspective image (Figure 1) shows the DPM overlaid on the terrain with the locations of landslides identified by the National Geospatial-Intelligence Agency (NGA) preliminary damage assessment, using before and after optical imagery (May 4 damage ass
Figure 1 Figure 2 NASA data and expertise are providing valuable information for the ongoing response to the April 25, 2015, magnitude 7.8 Gorkha earthquake in Nepal. The quake has caused a significant humanitarian crisis and has killed more than 8,000 due to widespread building damage and triggered landslides...

NASA/Caltech Team Images Nepal Quake Fault Rupture, Surface Movements
ARIA kinematic rupture model, April 25th, 2015. Using a combination of GPS-measured ground motion data, satellite radar data, and seismic observations from instruments distributed around the world, scientists have constructed preliminary estimates of how much the fault responsible for the April 25, 2015, magnitude 7.8 Gorkha earthquake in Nepal moved below Earth's surface (Figure 1). This information is useful for understanding not only what happened in the...

NASA's ARIA Project Provides New Look at Earth Surface Deformation from Nepal Quake
NASA and its partners are contributing important observations and expertise to the ongoing response to the April 25, 2015, magnitude 7.8 Gorkha earthquake in Nepal. The quake was the strongest to occur in that area since the 1934 Nepal-Bihar magnitude 8.0 event and caused significant regional damage and a humanitarian crisis. Scientists with the Advanced Rapid Imaging and Analysis project (ARIA), a collaboration between NASA's Jet Propulsion Laboratory,...
