Shield volcanoes include Active, Dormant and Extinct volcanoes.

Mount Takahe is a large, snow covered shield volcano standing 64 km SE ofToney Mountain in Marie Byrd Land, Antarctica. It is roughly circular, about 29 km across, and has a caldera up to 8 km wide. At 780 cubic km, it is a massive volcano. The volcano may have last erupted during the Holocene, and thus it is probably a potentially active volcano.

Mauna Loa is one of five volcanoes that form the Island of Hawaii. Mauna Loa is the largest subaerial volcano in both mass and volume, and has historically been considered the largest volcano on Earth. It is an active shield volcano, with a volume estimated at approximately 18,000 cubic miles (75,000 km3), although its peak is about 120 feet (37 m) lower than that of its neighbor, Mauna Kea. The Hawaiian name "Mauna Loa" means "Long Mountain". Mauna Loa's eruptions tend to be non-explosive and the volcano has relatively shallow slopes. Mauna Loa has probably been erupting for at least 700,000 years, and may have emerged above sea level about 400,000 years ago. The oldest-known dated rocks are not older than 200,000 years. The volcano's magma comes from the Hawaii hotspot, which has been responsible for the creation of the Hawaiian island chain over tens of millions of years. The slow drift of the Pacific Plate will eventually carry Mauna Loa away from the hotspot within 500,000 to one million years from now, at which point it will become extinct.
Volcanoes don't only occur on earth but there are also a number of volcanoes on Mars and Venus!

Arsia Mons is the southernmost of three volcanos (collectively known as Tharsis Montes) on the Tharsis bulge near the equator of the planetMars. To its north is Pavonis Mons, and north of that is Ascraeus Mons. The tallest mountain in the solar system, Olympus Mons, is to its northwest. Its name comes from a corresponding albedo feature on a map by Giovanni Schiaparelli, which he named in turn after the legendary Roman forest of Arsia Silva. Arsia Mons is a shield volcano with a relatively low slope and a massive caldera at its summit. The southernmost of the three Tharsis Montes volcanoes, it is the only major Tharsis volcano south of the equator. The volcano is 435 kilometres (270 mi) in diameter, almost 20 kilometres (12 miles) high (more than 9 kilometers (5.6 mi) higher than the surrounding plains), and the summit caldera is 72 miles (approximately 110 km) wide. it experiences atmospheric pressure lower than 107 pascals at the summit. Except for Olympus Mons, it is the biggest volcano in volume. Arsia Mons has 30 times the volume of Mauna Loa in Hawaii, the largest volcano on the Earth.
