Scientists think they see proof tsunamis on Mars


     Scientists point to satellite knowledge suggesting a major distribution of sediments over an outsized region at the sting of the Red Planet’s northern lowlands.

The US-led team argues that asteroid or comet strikes into AN ocean of water may have triggered the big waves. Such events could solely have occurred a lot of than 3 billion years agone once the earth was wetter and hotter. Today, Mars is dry and very cold, and any impact would merely dig out a dust-covered hole.

     But researchers have long speculated that the low, flat terrain in Mars’ northern hemisphere may have hosted AN ocean if the climate conditions were good. The nagging doubt with this theory has been the absence of AN recognizable bound – one thing the new study may currently facilitate make a case for.

   If tsunamis regularly inundated the “land”, dumping sediments and scouring new flow channels, they could over time have disguised what otherwise would are a lucid “coast”.”Clearly, it’s one of the implications of this work: to possess tsunamis, you must have AN ocean,” said Alexis Palmero Rodriguez from the Planetary Science Institute in Tuscon, Arizona. “So, we suppose this is often about to take away plenty of the uncertainty that surrounds the ocean hypothesis. Features that have in the past been understood as with reference to AN ocean are controversial; they will be explained by many, alternative processes. But the options we tend to ar describing – such as up-slope flows as well as massive boulders – will solely be explained in terms of wave waves,” he told BBC News.

     Dr Rodriguez and colleagues’ tsunami findings appeared on Thursday in the journal Scientific Reports. Their work centres on two connected regions of Mars, known as Chryse Planitia and Arabia Terra. The team claims that the sediments observed by satellite betray the action of 2 ancient mega-tsunamis.
