According to scientists, NASA’s InSight rover records the largest earthquake in the history of Mars
NASA’s InSight Mars Lander has recorded its largest earthquake ever on Mars.
According to new research published in the American Geophysical Union (AGU) journal Geophysical Research Letters, the international team said that on the night of Earth on May 4, the lander’s seismometer detected an earthquake that was at least five times larger than the next largest on record. on the red planet
“This was definitely the biggest earthquake we’ve seen,” Taichi Kawamura, lead author and planetary scientist at the Institut de physique du globe in Paris, France, said in a statement.
Co-author and seismologist John Clinton of the Swiss Federal Institute of Technology in Zurich said the energy released by the single marsquake is equivalent to the cumulative energy of all other marsquakes seen so far.

Clinton, who is co-leader with Kawamura on the marsquake service, said the waves recorded by InSight were so large that they almost saturated the seismometer.

Marsquake waves last about 10 hours.
No previous marsquake wave had exceeded an hour in duration.
The previous largest tremor, recorded in August 2021, was around a magnitude of 4.2, while the earthquake in May had a magnitude of 4.7.
The epicenter of the earthquake was outside the most seismically active region of Mars.
This seismic event was also rare because it had characteristics of both high and low frequency earthquakes.

Data from this large earthquake were released in October by the Mars Seismic Experiment for Interior Structure (SEIS) data service, the NASA Planetary Data System (PDS) and the Incorporated Research Institutions for Seismology (IRIS), along with the marsquake service catalog.

Seismology on Mars can help researchers better understand what lies beneath its surface and its evolution.
Most earthquakes are believed to occur due to fault movements.

InSight is believed to be nearing its operational end because dust has progressively covered its solar panels and reduced their power.
“We are impressed that almost at the end of the extended mission, we had this very remarkable event,” Kawamura said.
Based on the data collected from the earthquake“I would say this mission was an extraordinary success,” he continued.

“My power is very low, so this may be the last image I can send. Don’t worry about me – my time here has been productive and serene. If I can keep talking to my mission team, I will , but we’ll be closing here soon,” Insight’s 25-30-person team posted on Twitter on Monday. “Thanks for staying with me.”
Since landing in November 2018, the lander has provided information about Mars’ liquid core and the composition of its other inner layers. It has detected hundreds of earthquakes.
