There is scientific evidence that two large tsunamis swept across the surface of Mars.

According to the BBC News, this claim is strongly supported by satellite data, which shows a large sediment redistribution over an area located at the northern lowland region of Mars.

A US-based scientific team has explained that continuous asteroid strikes into a body of water could have caused the huge waves. These tsunamis are believed to have occurred approximately three billion years ago.

Alexis Palmero Rodriguez, a member of the Planetary Science Institute in Arizona, said that the main implication of this discovery is that to have tsunamis, then there must be oceans.

The findings of Rodriguez and his colleagues appeared in a nature journal named Scientific on Thursday, May 19. The team focused their research on the two regions of Mars, namely Chryse Planitia and Arabia Terra.

There are two events which explain the presence of tsunamis, and these are divided into old and new events.

The older event explains how energetic waves gather the remaining sediments such as boulders that are displaced from a higher elevation. Water, following the principle of gravity, will run downhill thus forming new channels.

The younger event is estimated to have occurred a few million years later when Mars' climate dropped significantly. The waves of tsunami became frozen in time as they tried to spread across the land surface.

The scale of sediment distribution serves as the basis for working out the impact of the tsunamis.

Due to these findings, the theory about the presence of an ocean in Mars is slowly gaining popularity again.
