New findings on the leading cause of sea level rise

For a long time, the situation of warming Earth has been identified as the main cause of melting glaciers, thereby increasing the sea level.

However, a study by Australian scientists published on June 3 showed that large earthquakes also caused sea levels to rise in the oceans, even with faster levels of variable status. climate change.

Professor Shin-Chan Han, of the University of Newcastle found that sea levels in American Samoa have risen five times the average of the world due to subsidence on the Earth's surface - the consequences after earthquake in Samoa-Tonga in 2009.

Professor warns the Pacific island nations that this phenomenon is more dangerous than climate change.

Based on images and data collected from satellites, Professor Han pointed out that in the eight years after the earthquake, land in the American island of Samoa dropped about 16mm / year, compared with 8-10mm / year. is recorded throughout the archipelago of the same name.

He called on governments to urgently reevaluate the forecast of rising sea levels due to the impact of large earthquakes with magnitudes above 8 because such magnitude earthquakes are likely to deform Earth's crust.

Professor Han concluded that the geological movement can greatly affect the rising sea level and should be considered side by side but changed due to climate change.
