NASA launches new radar to monitor earthquakes and volcanoes from space

It is thought that a team of small InSAR satellites can work in harmony with NASA's first InSAR satellite NASA-ISRO SAR Mission (NISAR) being developed. It is believed that many small satellites can collect data such as earthquakes, volcanic eruptions and landslides by adding data frequently together with rapidly developing processes and add them to NISAR's system.
Normally, researchers use ground sensors and GPS to detect distortions on the ground. InSAR is said to be complementary to ground measurements and will often guide ground radar placement. Orbital InSAR satellites can observe ground deformation because these areas swell with magma before volcanic eruption occurs. Starting from here, scientists can predict that a volcanic eruption will occur even if they cannot determine how big the eruption will be.
It is emphasized that CIRES type satellites will be 'dreamlike' in terms of rapid disaster response. Although it is not possible to process the information given by small satellites of CIRES type with similar precision compared to larger satellites, data can be obtained faster when a disaster occurs.
