KOMPAS.com- Spaceship, robot InSight, belonging to the national space agency of the United States (NASA) feel the shock earthquake strong, Marsquakes, which was detected last March.
Earthquake it comes from the area near the equator Mars which is known as Cerberus Fossae.
Quoted from Science Alert, Wednesday (7/4/2021), earthquake on Mars This was recorded at M 3.1 to M3.3 on March 7 and March 18.
Mars earthquake strengthening Cerberus Fossae as a region in red planet with the most active geological activity.
An equally powerful marsquake was also recorded to have rocked the same region in 2019.
Cerberus Fossae is a region in Red Planet which has many large gaps that are almost all connected or parallel. Where this series of gaps was formed when the planet’s crust was pulled open by dramatic volcanic events.

Volcanism is the main driver of earthquakes on Mars. However, planet Mars does not have tectonic plates like the Earth does, which can cause most of the earthquakes we can feel.
On the arid planet Mars, the Cerberus Fossae region is one of the main centers of volcanic activity and is an interesting area to study because of its geological instability, both past and present.
Geologists reveal that the ability to detect marsquakes is very new. Before NASA’s InSight robot detects the Mars earthquake, they had suspected the existence of an earthquake-strong earthquake on Mars for decades.

However, it was only after NASA’s InSight launched its Seismic Experiment for Interior Structures (SEIS) mission in early 2019 that scientists were able to capture its incontrovertible footage.
The lander of Viking 2 observed an event in 1976, namely the planet Mars is rocked by an earthquake small. But at that time, to ascertain the cause, it was impossible to rule out the wind or weather on this planet.
In contrast, InSight has now found solid evidence of more than 500 seismic events in just the last two years.
Most of the Marsquakes or Mars earthquakes that SEIS detected on NASA’s InSight robot were small, but those from Carberus Fossae were among the most obvious and strong enough seismic activity.

Geologists can predict that NASA’s InSight robot may have heard an earthquake from the Cerberus Fossae region six years before the spacecraft landed on Mars.
Returning in 2012, the research team used images captured by the HiRISE Mars Reconnaissance Orbiter camera to examine the area.
The NASA researchers finally found evidence of recent landslides, as well as large boulders that had rolled down steep slopes in several ravines on the Red Planet.
These rock avalanches appear to be consistent with the effects of earthquakes that occur on Earth.

This suggests that an earthquake on Mars may have just occurred and InSight’s new detection validates that theory.
The InSight mission was granted a two-year extension in January, and at that point the team hopes to create detailed records of Mars seismic activity.
To ensure the highest possible quality of data, they have started using a landing robotic arm to bury the SEIS instrument cables.
These efforts are believed to reduce wind noise, vibrations and temperature fluctuations, all of which could disrupt seismometers and disguise the possibility of detection of a marsquake earthquake on Mars.

Another challenge the InSight robots face, namely, the solar panels are covered in dust, which means that some lander instruments, such as the weather station, have to be temporarily turned off.
NASA spacecraft, Insight still has enough energy to keep SEIS running for another month or two, after which it must also go into hibernation mode.
Meanwhile, researchers are excited about the detection coming from Cerberus Fossae, and hope that a stronger earthquake is yet to come.
If NASA’s InSight robot hears or detects an earthquake on the planet Mars that is more powerful, then the vibrations may be deep enough to interact with the planet’s mantle and its core.
