Volcanic Eruption: Major Types
Encyclopædia Britannica, Inc.
Hawaiian- Quiet runny lava that flow easily downhill.
Strombolian- Violent and nosier than Hawaiian eruptions. Half-molten lumps of lava are thrown in short distances.
Vulcanian- Thick magma; large pieces of lava thrown greater distances than Strombolian eruptions. This type of eruption can destroy parts of the volcano.
Vesuvian- More explosive eruptions. Can destroy huge parts of volcano’s cone. Ashes and rock blown out for many hours.
Plinian- Very violent eruptions. Large portions of volcano collapse or blown apart.
Peléean- Eruptions expel large quantities of nuées ardentes or glowing, hot clouds of solid fragments that sweep down volcanoes on a rush of heated gases.

Ol Doinyo Lengai, Tanzania. Marco Fulle.
Ma’adim Vallis is located between the volcanic region of Tharsis, which harbours four volcanoes, including the largest in the Solar System, and the Hellas Planitia impact basin. The canyon, 20 km wide and 2 km deep, originates in the southern highlands close to the ‘dichotomy boundary’ and ends in Gusev crater. The dichotomy boundary is a narrow region separating the cratered highlands, located mostly in the southern hemisphere of Mars, from the northern hemisphere’s lowland plains. A sharp boundary is visible in the center, dividing dark material to the west and light material to the east. Scientists suspect that this feature is most likely the edge of a basaltic lava flow. Wrinkle ridges are clearly visible on the surface of the lava flow. They were most likely formed by compressive forces.

The Most Elevated Volcano in The Solar System’s History: Olympus Mons
This view shows the Olympus Mons on Mars, the highest volcano in our Solar System. Olympus Mons has an average elevation of 22 km and the caldera has a depth of about 3 km. The image was taken from a height of 273 km in orbit 37 by the High Resolution Stereo Camera (HRSC) on ESA’s Mars Express.

An Alaskan Volcano Erupts

What is happening to that volcano? It’s erupting! The first person to note that the Aleutian Cleveland Volcano was spewing ash was astronaut Jeffrey N. Williams aboard the International Space Station. Looking down on the Alaskan Aleutian Islands two weeks ago, Williams noted, photographed, and reported a spectacular ash plume emanating from the Cleveland Volcano.
Jupiter and Io
While hunting for volcanic plumes on Io, NASA’s Hubble Space Telescope captured these images of the volatile moon sweeping across the giant face of Jupiter. Only a few weeks before these dramatic images were taken, the orbiting telescope snapped a portrait of one of Io’s volcanoes spewing sulfur dioxide “snow.”

The view from the volcano’s rim, 11,380 feet above the ground. At 1,300 feet deep, the lava lake has created one of the wonders of the African continent.
