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.

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.
Pahoehoe lava, which has a smooth, rope-like texture and forms by flowing rapidly and cooling quickly, is more likely to form lava tube caves due to its ability to retain heat and flow for long distances before solidifying. Aa lava, with its jagged and blocky texture, tends to move more sluggishly and is less likely to create extensive tube structures.
"Basic", or low-silica, basalt lava, as its viscosity is relatively low.
butter........juicy buttery butter........yummy bacon and eggs and opps forgot the best part baby sausage weinie things! HAHA no its formed at your mamas house lol! stupid i no but just laugh.....
Yes. Ape Cave - two mile long lava tube, Gardner Cave - 1000' long limestone cave Ice Cave - 400' long lava tube Source: http://www.goodearthgraphics.com/showcave/wa.html
They both depend on eruptions for their formation but lava tubes form only in large flows of low-viscosity, basaltic,lava. I don't know if this applies to Mt. Pinatubo.
Most caves are in limestone or dolomite rocks. Some (e.g. Carlsbad Caverns) are in gypsum rocks. But caves can also exist in lava deposits (e.g. lava tube caves), marble rocks (i.e. metamorphosed limestone), and many other types of rocks at lower rates, depending on various variables.
Most are in limestone uplands (as karst features). Some volcanic areas erupting basaltic lava have lava-tube caves. There are also minor caves in various rocks dotted around the world, such as fissure-caves created by mass-movement.
Lava Beds National Monument is located in northeastern California near the town of Tulelake. It is situated in the southern part of the Cascade Range and is known for its rugged lava landscape, lava tube caves, and Native American rock art sites.
Not a pattern in a mathematical sense, no, but the vast majority of the world's caves are in limestone uplands of appropriate structural and hydrological characteristics for cave development. They are very rare in Chalk, for instance, even though Chalk is a type of Limestone. Limestone is a very common and widespread range of sedimentary calcium-carbonate rocks, so caves are found in very many countries. Another important but much rarer type of cave is the Lava Tube, but this can only form in flows of low-viscosity lava, retricting them to a few locations.
