Volcano on Io
This false color picture taken by the Voyager spacecraft shows a volcano erupting on the surface of Io right along the moon's limb. This picture was the first to show an active volcano in the solar system other than those on Earth.

Volcanoes:
A volcanoe is any vent in the crust of the Earth or other planet or satellite (e.g., Jupiter's Io), from which molten rock, pyroclastic debris, and steam issue.
Volcano
In order for vulcanism to occur, (1) there must be a fluid (low viscosity) phase, (2) it must be buoyant (have a lower density than the crust), (3) must be a heat source to keep in molten (tidal, radioactive, remnant, solar), ...

Volcanoes can be caused by "mantle plumes". These so-called "hotspots" , for example at Hawaii, can occur far from plate boundaries. Hotspot volcanoes are also found elsewhere in the solar system, especially on rocky planets and moons.

Volcano craters are above the surrounding area on mountaintops while the craters from impacts are below the surrounding area with raised rims. The craters on all of the moons except Io, Mercury, and most of the ones on Mars are from impacts.

A break or vent in the crust of a planet or moon that can spew extremely hot ash, scorching gases, and molten rock. The term volcano also refers to the mountain formed by volcanic material.

She says volcanoes are an important area of research as more and more people live and work in the path of volcanoes.
The main volcano, and also the highest mountain in the solar system, is Olympus Mons. This critter is about 600 km across, reaching an overall height of about 25 km.
The largest volcano in the solar system also happens to be the largest mountain on Mars. Olympus Mons is three times taller than Mt. Everest at a towering 27 kilometers.

Third, the largest volcano in our solar system, Olympus Mons, lies on Mars. It is 24 km (15 miles) high, and the top of it is 70 km (40 miles) wide; the base is about 600 km (375 miles) wide.

As the dust began to clear from the Martian sky during the Great Dust Storm of 2001 the high volcanoes of the Tharsis region on Mars began to pop put from the tops of the dusty haze.
Some bright spots are visible by the earth-light when the moon is a thin crescent, which were supposed by Herschel to be volcanoes in eruption.
Volcanoes form along zones of subduction, because the oceanic crust tends to be remelted as it moves into the hot mantle and then rises to the surface as molten lava.
Some of the solar system's largest volcanoes occur in Tharsis. Olympic Mons, a structure showing all the characteristics of a basaltic volcano, reaches an elevation of more than 25 km (15.5 mi) and measures more than 600 km (370 mi) across its base.
The highest known surface point on Mars is a huge volcano known as 'Olympus Mons'. It stretches 24km high above the lava plains around it and it has a base measuring 600km. Mars has an average surface temperature of about -23°C.
Before the arrival of Voyager at Jupiter, a few brave theorists (Stanton Peale, Patrick Cassen and Ray Reynolds) had the idea that Io may have volcanoes, and their concepts were correct.
Mars also has numerous enormous volcanoes—including Olympus Mons (c.370 mi/600 km in diameter and 16 mi/26 km tall), the largest in the solar system—and lava plains.
4 billion years ago, the surface had cooled enough to form a crust, still heavily populated with volcanoes which released steam, carbon dioxide, and ammonia.
It formed originally from molten lava which possibly issued from an ancient Martian volcano, about 4.5 billion years ago.
Powerful Earth-based telescopes can observe volcanoes resurfacing Io continuously. Europa is covered with an extremely smooth shell of water ice.
First, there are the volcanos, which are usually higher than those on Earth. The Olympus Mounts, the largest volcano in the solar system, rises 25km above the surface (three times the height of Mt. Everest) and is 600km in diameter.

But the Minoan civilization was wiped out around 1700 BC by the explosive eruption of a volcano on the island of Thera about 120 km north of Crete.
Volcanic craters usually crown conical volcanoes and form the opening of the volcanic vent, where lava pools when magma is rising to the surface.
The first infrasound waves to be observed were from the eruption of the Indonesian volcano Krakatoa in 1883, which shattered windows hundreds of kilometers away and circled the world seven times.
It no longer has volcanic activity because it has cooled down and there isn't enough radioactive materials in the Moon to produce enough heat to create new volcanoes. Bombardment still occurs but not like in the good ol' days. [Fortunately.
If you somehow survived the radiation you would still be in trouble, because Io is covered with giant volcanoes which erupt with extreme frequency.
Mars has wind and volcanoes. Its atmosphere is colder and much thinner than ours, but has wind and has clouds made of water vapor (and dry ice) around its polar caps. Mars does not have an Ozone (O3) layer similar to the Earth's.
Scientists realized that they were looking at several huge volcanoes.
The largest of these volcanoes is Olympus Mons (see below). At 15 miles high it is nearly three times the height of Everest and comparable in area to the size of Poland.
What is it like on Mars?
The surface is a cold desert. There are volcanoes, mountains, valleys, and vast plains. The largest volcano in the solar system is on Mars. It is called Olymp. Spacecraft from Earth have landed on Mars.
New material constantly finds its way to the surface through volcanoes and cracks in the ocean floors (see seafloor spreading). Much of the Earth's surface is less than 100,000,000 years old; the very oldest parts of the crust are as much as 4.
