Excellent question, and perhaps someday we'll learn that. We do know that large volcanoes do form on Earth, but on Earth the forces of wind and water can erode the mountains and wear them down. On Mars, there is very little atmosphere, and very little water, so there's not much weathering.
Scientists think this is probably due to larger eruption rates and to lower gravity on Mars than on Earth.
