An international study with Catalan participation from the Universitat Autònoma de Barcelona (UAB) has revealed that the coasts on Mars were destroyed by tsunamis. The study has been published in “Scientific Reports-Nature” and explains that two tsunamis that were produced millions of years apart reduced the level of the ocean and made the climate significantly colder. The tsunamis appear to have been created by the impacts of 30-km-wide meteors. The discovery gives an answer to the question of why scientists couldn’t recognise its shorelines if there really had been an ocean on Mars about 3.4 billion years ago.
