Mars is much less tectonically active than Earth, and marsquakes are unlikely to have provided seismic waves of the required magnitude. [10] Most sizable craters on Mars date to the Late Heavy Bombardment , 4.1 to 3.8 billion years ago (the Noachian period), and are older than the landslide deposits in Valles Marineris.
It was the largest recorded ocean wave ever to strike the United States West Coast, and Harrington's report that that wave crested at the height of the lantern and that it buried the area between the lighthouse and the bluff in water which rose to the lighthouse's balcony suggests a possible wave height of 200 feet (61 m).

Mojave is a rayed crater, another indication of its youth, and is the largest such crater on Mars. Based on crater counts of its ejecta blanket , it is thought to be about 3 million years old. It is believed to be the most recent crater of its size on Mars, and has been identified as the probable source of the shergottite meteorites collected ...

The U.S. Navy historically took the design position that the largest wave likely to be encountered was 21.4 m (70 ft). Smith observed in 2007 that the navy now believes that larger waves can occur and the possibility of extreme waves that are steeper (i.e. do not have longer wavelengths) is now recognized.

Martian dust devil photographed by the Mars Reconnaissance Orbiter. This dust devil is 800 m (2,600 ft) tall and 30 m (98 ft) wide. This dust devil is 800 m (2,600 ft) tall and 30 m (98 ft) wide. The existence of dust devils on Mars was confirmed by analysis of data from the Viking probes in the early 1980s.
Some of the largest volcanoes on Mars lie relatively close to the proposed “Noctis volcano.” Shown here: 1) Olympus Mons, the tallest known volcano in our solar system. 2) The Tharsis plateau ...
