The strongest earthquake recorded by NASA was recorded on the planet Mars and lasted for 10 consecutive hours. However, the epicenter of the earthquake could not be detected.

"The energy released by this single earthquake is equal to the total energy of all the other earthquakes we have recorded so far," said John Clinton, a seismologist at the Swiss Federal Institute of Technology in Switzerland.

NASA's InSight recorded a magnitude of 4.7, while the previous record was from August 2021 with 4.2. The number may not sound huge from Earth's record where the strongest recorded was 9.5 on the Richter scale, but remember we're talking about a planet we thought was seismically inactive until InSight began recording it in 2019.

Mars has no tectonic plates, nor does it have a single global magnetic field, which is taken as a sign that the planet's interior is not particularly active. But the InSight data revealed that earthquakes do exist, indicating volcanic activity.

By analyzing seismic waves, scientists try to understand the structure of the Martian subsurface, identifying sedimentary rocks and possible volcanic activity within its crust. The fact that the epicenter of the new earthquake cannot be found suggests that it may be related to something hidden beneath the crust.

Also, the fact that this particular earthquake combined high and low frequencies has scientists concerned, as earthquakes on Mars usually fall into one category or the other.
