The Type 3 Chi-Nu medium tank retained the same hull and suspension of the Type 1 Chi-He, with the addition of an enlarged turret ring for the new large hexagonal gun turret with a commander's cupola. [2] [15] The more powerful main armament, a Type 3 75 mm tank gun, was based on the Japanese Type 90 field gun. [16]
One other form a lava tube can take is the tube-in-tube which can form inside lava tubes if the linings of the walls are weak enough to lean inward, forming a new floor above the old. Tube-in-tubes are generally noted to form during the last lava draining through the main lava tube. [1] [2] [3]

Pillow lava on the ocean floor of Hawaii. Pillow lavas are lavas that contain characteristic pillow-shaped structures that are attributed to the extrusion of the lava underwater, or subaqueous extrusion. Pillow lavas in volcanic rock are characterized by thick sequences of discontinuous pillow-shaped masses, commonly up to one meter in diameter.
Large volumes of basaltic lava covered a large expanse of Siberia in a flood basalt event. Today, the area is covered by about 7 million km 2 (3 million sq mi) of basaltic rock, with a volume of around 4 million km 3 (1 million cu mi).
On 11 November, it was reported that the lava field extended to 70 km 2 (27 sq mi) and more than 1 km 3 (0.24 cu mi) in volume - the largest in Iceland since the Laki eruption of 1783. [3] [18] The eruption ended on 27 February 2015. The Holuhraun lava field measures more than 85 km 2 (33 sq mi) and the volume is around 1.6 km 3 (0.38 cu mi).
The word lava comes from Italian and is probably derived from the Latin word labes, which means a fall or slide. [2] [3] An early use of the word in connection with extrusion of magma from below the surface is found in a short account of the 1737 eruption of Vesuvius, written by Francesco Serao, who described "a flow of fiery lava" as an analogy to the flow of water and mud down the flanks of ...
