They form in relatively low-viscosity "basic" (low-silica, basalt) lava flows by the surface solidifying over still-flowing molten rock. If the molten lava drains away it leaves a cavity within the mass of the flow. Main lava caves of the word are on Iceland and Hawaii.
Fingal's Cave, on the Isle of Staffa, is in columnar flood-basalt but is a marine-erosion feature.

What is a lava tube cave?
A lava tube cave is a natural tunnel formed by the flow of lava, creating a channel for molten lava to move through during a volcanic eruption. When the lava flow stops, the tube can cool, leaving behind a cave-like structure with unique geological features.
Where do lava tube caves form?
Lava tube caves form when low viscosity lava flows beneath the hardened surface of lava flow while the volcano is active. Then when the volcano is dormant or extinct, it leaves cave like channels.
Can intense heat form a cave?
no +_++ With one exception, the Lava Tube! This results from still-molten lava flowing out from beneath the solidified crust on a mahjor lava flow.
What cave forms when molten rock flows out from beneath a hardened surface of lava and leaves behind an underground chamber?
This is called a lava tube.
If a lava tube cave is just below the surface then how can one be considered a deep cave?
Cave depths are measured from the altitude of the upper most portion of the cave with the altitude of the lowest portion of the cave passage. In the case of a lava tube cave, the passage is related to the lava flowing down the slope of the landscape. Since a lava cave can be over 8 km long, it is possilble that the upper portion of the cave is over 300 meters higher than the lower portion of the cave. It can be very strenous to travel from the top of such a cave to the bottom and possibly back out the entrance from which you came. Ref: http://www.caverbob.com/lava.htm

Yes: look up its own web-site, mauicave.com.
What is the difference between lava flow lava fountains and lava tubes?
A lava flow is basically a stream of lava on the surface. A lava tube is an underground cave through which lava flows downhill. A lava fountain is lava shooting into the air out of a volcano in much the same manner as a water fountain.
Where are the largest lava tube caves found?
The most famous spot for lava tubes on Earth is Hawai'i. Because of the geography, the Lava Tubes on Big Island are the biggest in the World. Kazumura Cave is 61.407 m long and has a height difference of 1102 m from end to end.
Where is the Thurston lava tube located?
The Thurston Lava Tube is located in Hawai'i Volcanoes National Park on the Big Island of Hawai'i. It is a popular tourist attraction that offers a unique opportunity to explore a cave-like tunnel formed by flowing lava.
