It's approximately 374 miles across (roughly the size of Arizona), 16 miles tall, and has a 50-mile-wide crater at its summit. In the paper, the authors argue that about 300,000 years ago, magma from Mars' interior rose to the surface.
This is probably due to larger eruption rates and to lower gravity.
In addition, Mars is home to the largest volcano in the solar system: Olympus Mons, 600 kilometers (370 miles) in diameter, about the size of the entire state of Arizona, and 21 km (13 mi) high, over twice as high as Mt. Numerous small mounds having summit craters are found in various
