SWOT Satellite Mission is being jointly operated by NASA (USA) and CNES (France). Under this mission, International Surface Water and Ocean Topography are studied. Recently, this mission has captured the most unique and terrible tsunami to date. By looking at this, one can imagine how catastrophes might have occurred on Earth in the past and a situation of concern has arisen as to whether, in the future, there will be a catastrophe on Earth and a part of the Earth will be submerged in water.

Capturing Tsunami Patterns with SWOT satellite:
The SWOT satellite gathered water elevation data in Dickson Fjord on 17 September 2023, just a day after the rockslide unleashed the tsunami. This data was later compared with baseline measurements from early August, giving researchers a unique insight into water level changes. According to the visual data, the water levels along the fjord’s northern wall were as much as 4 feet (1.2 meters) higher than on the opposite side.
“SWOT happened to fly over just when the water had piled up high against the fjord’s northern wall,” explained Josh Willis, a sea-level researcher at NASA’s Jet Propulsion Laboratory. “Capturing the wave’s shape this way was something previously impossible before SWOT.”
This groundbreaking observation enabled scientists to measure a wave that would otherwise have gone unnoticed in such a confined setting.
200 Meter High Tsunami and Earthquake Tremors for 9 Days:
The satellite captured this tsunami when it was passing through the walls of a fort in Greenland. This study has been published in the Science Journal. The incident was in September 2023. An international research team including seismologists, geophysicists, and oceanologists analyzed the answers received from the satellite for a full year and has now submitted the report. The report states that a major landslide occurred in Greenland in September 2023. Which has given rise to some incidents that have worried scientists around the world. This caused a 200-meter-high tsunami and earthquake tremors were felt in many parts of the world for 9 days.
