Pu’u O’o vent, Kilauea volcano. Pahoehoe lava. Pahoehoe is a smooth and continuous lava crust. Pahoehoe forms when the effusion rate is low and consequently the velocity of lava flow is slow 2. Pahoehoe lava flow is usually at least 10 times slower than typical aa lava flow 5. Higher effusion rate results in lava flow being shattered which is how the rubbly and clinkery aa lava surface.
The levees can grow very high, lifting the lava flow well above the surrounding slopes. In the 1880’s the local population said it has been erupting for 15 to 20 years already. This pattern of long-lasting eruptions has continued since. The eruptions are accompanied by explosive activity with ash and pyroclastic flows, especially at the beginning of a new episode, but these explosions are.
A section of sea cliff above the massive 'firehose' lava flow on Hawaii's Kilauea Volcano collapsed and splashed into the ocean as tourists and geologists watched.More likely in Yellowstone than a large explosive caldera-forming eruption is eruption of a lava flow, which would be far less devastating. Since Yellowstone’s last caldera-forming eruption 640,000 years ago, about 30 eruptions of rhyolitic lava flows have nearly filled the Yellowstone Caldera. Other flows of rhyolite and basalt (a more fluid variety of lava) also have been extruded outside.Lava oozing out of cracks for two weeks in rural Hawaii neighborhoods took on new characteristics as fresher magma mixed with decades-old magma, sending a flow toward the ocean today.
A shield volcano is a type of volcano usually composed almost entirely of fluid lava flows. It is named for its low profile, resembling a warrior's shield lying on the ground. This is caused by the highly fluid (low viscosity) lava erupted, which travels farther than lava erupted from a stratovolcano, and results in the steady accumulation of broad sheets of lava, building up the shield.
The Hualalai volcano is probably best known for the black gold that comes from its slopes: Kona Coffee. Hualalai is an active volcano but has not erupted for a while. The last eruption of lava dates back to 1801, and the last damaging seismic swarm of earthquakes (probably caused by a shallow intrusion of magma) happened in 1929.
The area is still extremely dangerous, says the US Geological Survey.
A volcano is a rupture in the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface. Earth's volcanoes occur because its crust is broken into 17 major, rigid tectonic plates that float on a hotter, softer layer in its mantle. Therefore, on Earth, volcanoes are generally found where tectonic plates are.

At many locations, glacier ice slowed or halted the movement of lava flows. Elsewhere, glacier ice channeled lava flows and allowed them to travel several miles from the base of the volcano. At Mount Rainier, the 40,000 year-old Ricksecker Point lava flow pooled at the juncture of the ancestral Nisqually and Paradise Glaciers.

Old Volcano Resource Map (MHFU) The Old Volcano location first appeared in Monster Hunter. It consists of an active volcano and the surrounding area, it is also called the Volcanic Belt.Hunters start out at the base of the mountain, and may journey through the molten center.
Lava viewing is a must-do activity if you are lucky enough to be on the Big Island while one of the volcanoes is actively erupting. Hawaii wouldn’t exist if it were not for the continuous volcanic activity that created all the islands, and seeing this happening in “real-time” is, for many people, a once in a lifetime experience.
