The robot spacecraft InSight is equipped with a seismometer sent by NASA to explore Mars. Landed and surveyed the surface of Mars during the year 2018–2022 and hundreds of earthquakes have been detected on Mars. Seismologists said that Seismic waves generated by an earthquake or shock can slow down or speed up. It depends on the type of material the waves travel through. This allows measuring the movement of the waves to predict what the interior of the star looks like.
The latest research team is led by planetary scientists from the Swiss Federal Institute of Technology in Zurich. Switzerland Revealing new information after studying the earthquake that resulted from a meteorite hitting Tempe Terra, a high area on Mars, on Sept. 18, 2021, causing a 4.2 magnitude earthquake and leaving a hole approximately 130 meters wide on the opposite side. Crossing with the InSight landing site The seismic waves from the event have provided new clues about the Red Planet’s deep interior.
Researchers revealed that Shocks from the other side of the star create seismic waves that travel deep within the star. Including the core Wave behavior indicates a layer of molten silicate approximately 150 km thick surrounding the core. This molten region is located in the star’s body. which is the structural layer between the star’s crust and the star’s core and also calculated the size of the new core. It was found to have a diameter of approximately 3,350 km and a volume approximately 30% smaller than previously thought.

Seismic activity at Mount Anak Krakatau intensified on October 28, 2023, prompting Indonesian authorities to issue a 5 km (3.1 miles) exclusion zone around the main crater. The heightened activity included a range of earthquakes and internal vibrations indicative of potential eruptions.
