NASA can also apply its airborne instruments to assess earthquake impact. With ARIA, maps of an earthquake can be made within a day to several days afterwards, depending on the availability of earliest post-earthquake radar observations. NASA Advanced Rapid Imaging and Analysis (ARIA) uses radar and optical remote sensing, GPS and seismic observations to investigate earthquakes. Meanwhile, aftershocks - subsequent earthquakes that occur after the initial event - may continue for weeks, causing additional damage and hampering recovery. Since 2015, more than 10,000 people around the world have died from earthquakes and tsunamis. Earthquakes near coastlines or under oceans can generate tsunamis severe enough to cause extensive damage to coastal regions. Large-magnitude earthquakes near cities and towns can cause catastrophic devastation, destroying buildings and infrastructure. This is feasible by using an immersive 3D environment for earthquake disaster simulation. Training of the mind and body can also be achieved in a virtual environment where the risks associated with a real earthquake shaking can be eliminated. During earthquake response and recovery we can help identify damaged infrastructure, support search and rescue, and determine other impacts with our expertise in sensor networks and remote sensing. People in regions with frequent earthquakes often exhibit better response due to past experience.
