Scientists have found on Mars traces of two tsunami – Interfax

Moscow. May 19. INTERFAX.RU – Scientists have found on Mars, the next major tsunami that have arisen due to the fall of two asteroids, <-! Noindex -> writes <-! / Noindex -> EurekAlert! The researchers’ work was published by the journal Scientific Reports.

According to the hypothesis, on the northern hemisphere of Mars could be cold salty liquid ocean to a depth of 1.5 km, vaporized, according to scientists, because of the abrupt climate change.

An international team of scientists, geophysicists from the EU, US and China, studying relief, found that about 3.4 billion years ago on Mars fell two asteroids. After they left two impact craters with a diameter of more than 30 km each. Scientists have conducted modeling and suggested that the disaster occurred two tsunami waves of about 100 meters each in height.

After the first tsunami is believed to scientists on land huge masses of water were thrown. As a result of the retreat of water traces of channels and ridges, which extend to a distance of hundreds of kilometers away.

“These projections were frozen on the surface when the water is gone as far as possible and did not return back into the ocean, this suggests that the ocean while already partially frozen, “- said one of the authors of Alberto Faren

the second asteroid fell later, during the existence of the planet frozen ocean.. With the fall of the second celestial body, a new wave, but the water quickly froze within the second line is not returned to the ocean.

According to the observations of scientists, the projections have kept their borders. This may be a sign that the water was saturated with salt. Regarding the controversy about the existence of life on Mars, this information may be of academic interest, because the salt not only helps to retain water in a liquid state at low temperatures, but, in the case of a high dose of salts, is toxic to living organisms.

According to existing hypotheses, 3.2-3.7 billion years ago, Mars had a dense atmosphere and hydrosphere – because of this and humid climate that could support life on the planet
