Mauna Loa is also another example of a shield volcano. It is one of the five volcanoes on Hawaii. It covers and area of around 5,271 cubic kilometers. The last known eruption was in 1984, it has remained quiet for 19 years the longest amount of time that Mauna Loa has ever stayed quiet for.
Mount Terror is a large extinct shield volcano located in Antarctica. It has a height of 3,230 meters high. The rock that makes up this volcano ages from 820,000-1.75 million years old.
