Recently, a research team composed of scientists from Chile, the United Kingdom and other countries announced the discovery of marine sediment evidence of the largest earthquake in human history. Studies have shown that the earthquake occurred in the northern region of Chile about 3800 years ago, with a magnitude of 9.5, and caused a tsunami that spread to new Zealand more than 8,000 kilometers away, severely destroying the coastline and making the coastal area uninhabitable for 1,000 years.

Recently, researchers at the InSight Mars Seismic Service Center reported in the Earthquake Record that the seismometers on NASA's InSight Mars lander recorded the two largest Martian earthquakes to date, with magnitude 4.2 and magnitude 4.1, respectively. They are the first Martian seismic event recorded by the lander over a distance, and they are 5 times more intense than the largest earthquake previously recorded. Seismic wave data from both events could help researchers learn more about the interior of Mars. (Source: China Science Daily)

Recently, the State Key Laboratory of Tropical Marine Environment at the South China Sea Institute of Oceanography, Chinese Academy of Sciences, has made new progress in the study of the mechanism of global warming supermass ocean circulation change. The study found that in the context of global warming, changes in upper ocean circulation are mainly driven by sea surface warming, while changes in wind stress play only a secondary role. The results have been published in Advances in Scientific Research. (Source: South China Sea Institute of Oceanology, Chinese Academy of Sciences)
