Scientists have built a "quake room" for testing marsquakes on Earth

NASA's InSight Lander made the history of space exploration in April discovered the shimmy on Mars with a seismometer. A sensitive instrument is designed to study marsquakes, but these earthquakes are not similar to those we know on Earth.

Researchers at ETH Zurich University in Switzerland wanted to know what the feel of the marsquake was, so InSight seismometer data was entered into the earthquake simulator and compares the Earthquake and Moon quake data campaign.

The video shows researchers sitting in a copy of a room in the house, along with glasses of water, wall decorations and plants on the shelf.

The earthquake gave them a sharp and rapid stress. Moonquake was built slower. Marsquake created a lot of movement in the simulation room and caused researchers to grab glasses of water in order not to fall from the table.

So far, marsquets have been discovered to be very weak. "The researchers had to raise marsquake signals with a factor of 10 million to make a silent and remote tremor perceived in comparison with similarly reinforced moons and inseparable earthquakes," said NASA.

Scientists have identified two types of marsquakes: a high-frequency dark force in style and a low-frequency earthquake, which may have occurred at a greater distance from the seismometer. "Compared to the duration of the earthquake, both types of marsquakes last longer," said Simon Stähler, a research seismologist at ETH Zurich.

InSight, which landed at the end of 2018, is on a mission to explore the interior of Mars hoping to learn more about how rocky planets are formed.

We are still at the beginning of the study of marsquakes, but scientists hope that vibrations will tell more about the structure of the Red Planet. The earthquake experience is personally a visceral way to feel the difference between the seismic activity on Earth and the Earth on a distant planet.
