Detailed explanation-1: -The largest of the volcanoes in the Tharsis Montes region, as well as all known volcanoes in the solar system, is Olympus Mons. Olympus Mons is a shield volcano 624 km (374 mi) in diameter (approximately the same size as the state of Arizona), 25 km (16 mi) high, and is rimmed by a 6 km (4 mi) high scarp.

Detailed explanation-2: -Rising gradually to more than 4 km (2.5 mi) above sea level, Hawaii’s Mauna Loa is the largest active volcano on our planet.

Detailed explanation-3: -That’s right-Mars has a volcano, and it’s really, really big. Olympus Mons is a shield volcano located in Mars’ western hemisphere. It is the largest volcano in the solar system at 72, 000 ft tall (two and a half times the height of Mount Everest) and 374 miles wide (nearly the size of the state of Arizona).

Detailed explanation-4: -Only two craters are visible here, indicating that Olympus Mons is young, probably the youngest volcanic feature on Mars. By some estimates, the most recent large volcanic eruption at Olympus Mons occurred only 25 million years ago.

Detailed explanation-5: -The highest mountain on Mars is also the highest mountain and volcano in the entire solar system. It is called Olympus Mons and is 16 miles (24 kilometers) high which makes it about three times higher than Mt. Everest.
