Caconemobius fori is a small cricket, approximately 9 mm (0.35 in) in length. [2] It lacks wings but is capable of jumping significant distances when disturbed. This species is darkly colored with an overall shiny quality, causing them to blend in extremely well with the freshly solidified lava that makes up their habitat.
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 ...
Pele's tears (closest Hawaiian translation: "nā waimaka o Pele") are small pieces of solidified lava drops formed when airborne particles of molten material fuse into tearlike drops of volcanic glass. Pele's tears are jet black in color and are often found on one end of a strand of Pele's hair.
A lava spine (or lava spire) is a vertical growth of solid lava that is forced from a volcanic vent. A lava spine can either be formed by viscous lava slowly being pushed out of the vent, or by magma that has solidified within the vent before being pushed out.
The deposited lava along the North Shore of Lake Superior is 7,620 m (5 mi) thick. [9] This was a fast-spreading rift; the resulting basalts show little interaction with the then-existing rock. These immense volumes of mafic lava were generated in two major pulses, mostly via a hot mantle plume. [21]
A notable geological feature is the solidified lava bubbles, which the locals have named "basalt yurts". [4] < [2] Around 8,000 years ago during the Holocene, the Khorgo cinder cone erupted, with lava flooding the valley below, forming a lava dam which created the Terkhiin Tsagaan lake. [3]
[5] [6] This lava formed a hard cap over the Payne Cliffs Formation. [5] At Lost Creek Lake, the lava attained its maximum thickness of 730 feet (220 m) and thinned to about 100 to 200 feet (30 to 61 m) to the north of Medford. Andesite lava cap. Since the Olson eruption, the Rogue River has eroded 90 percent of the solidified lava.
As the lava flowed across the wet sod, the water of the marsh started to boil, the vapour rising through the lava forming lava pillars from drainpipe size up to several meters in diameter. [4] As the lava continued flowing towards lower ground in the Mývatn area, the top crust collapsed, but the hollow pillars of solidified lava remained. The ...
