<\/p>\nWhat did SWOT manage to capture
<\/h2>\n<\/p>\n
As reported, approximately 70 minutes after the earthquake, SWOT passed near the affected area and recorded the sea surface in two dimensions. Its radar system measures height differences down to centimetres.The satellite detected not only the major tsunami wave, but also a sequence of shorter-wavelength waves. These are often described as dispersive waves. Researchers from institutions such as San Diego State University and Scripps Institution of Oceanography worked with teams from DTU Space and the Pontificia Universidad Cat\u00f3lica de Valpara\u00edso to analyze the data. Their combined effort helped to reconstruct the wave field in detail.<\/p>\nUnderstanding near-trench slip in subduction earthquakes.
<\/h3>\n<\/p>\n
Earthquakes that occur near subduction trenches behave differently from earthquakes inland. In these areas, one tectonic plate slides beneath another. A slip near the trench could suddenly displace the sea floor.This near-trench slip was detected indirectly through satellite observations. According to a study published in Science, the spreading waves point to the rift occurring at a shallow depth, reportedly less than 10 kilometers below sea level. It is difficult to monitor such areas using ground-based seismic networks. The equipment is simply too far away or spread too far across the ocean.<\/p>\nLimitations of traditional tsunami sensors
<\/h3>\n<\/p>\n
Systems such as DART buoys still play an important role. They measure pressure changes in deep water and can track tsunami wave height.In the Kamchatka event, many of these sensors recorded the major tsunami wave. According to Phys.org, a nearby buoy measured the height of the trough from peak to about 1.32 meters. Yet they struggled to capture better wave structure. Shorter wavelength signals become weaker at depth. Additionally, the distance between sensors leaves large gaps in coverage. SWOT’s wide-swath scanning allowed scientists to see patterns that would otherwise remain hidden.<\/p>\nWhat do wave patterns reveal?
<\/h4>\n<\/p>\n
The trailing wave train observed by SWOT provides important clues. Experts say these scattered waves may reflect how the fault moved along the trench.In this case, signals suggested rupture in a specific section of the subduction zone, roughly between 49.5\u00b0N and 52.5\u00b0N along strike. Names such as Ignacio Sep\u00falveda and Alice Gabriel have been linked to interpreting these results. Their observations indicate that these waves help refine models of tsunami generation.<\/p>\nWhy does this matter for risk planning?
<\/h4>\n<\/p>\n
Understanding how tsunamis form near their source is important for improving risk models. The new satellite-based observations add a layer of detail that was previously missing.With clearer data, simulations can better reproduce real-world wave behavior. This could lead to improved forecasting tools and more reliable warning systems. Bjarke Nilsson, who contributed to the data processing efforts, points out that integrating satellite inputs into the modeling framework could help in future threat assessments.<\/div>\n","protected":false},"excerpt":{"rendered":"A recent study involving a powerful earthquake near Russia’s Kamchatka Peninsula has offered a closer look at how tsunamis are triggered beneath the ocean surface.
