The lava tube allowed the fluid pahoehoe lava to retain heat and flow long distances. In less than a year, overflow from the lake created a broad and low shield about 55 meters (180 ft) above Kūpaʻianahā. Lava streams were first visible from the town of Kapaʻau in November, 1986. In the course of that month, lava cut a swath through ...
The foreground pahoehoe lava is from the 2003 flow. Lava flows from the Kīlauea volcano eruption closed the road in 1969. In 1979, the road was reopened, but it was cut again in 1986 by a lava flow from another eruption of Kīlauea. [6] [7] As of 2014, Chain of Craters Road is about 19 miles (31 km) long to Holei Sea Arch where it terminates ...
A lava coil is a spiral or scroll-shaped lava formation occurring when relatively low viscosity lava such as Pahoehoe solidifies along a slow-moving shear zone in the flow. The shear produces a Kelvin–Helmholtz instability that forms spiral-shaped patterns. Depending on the side of the flow the spiral is clockwise or anti-clockwise.
Bonito Lava Flow, with O'Leary Peak and Darton Dome in background. There are three lava flow areas in the American state of Arizona: Bonito Lava Flow - . The basalt lava flow extruded from the base of Sunset Crater around 1180. The flow surface consists of pahoehoe. Kana-a Lava Flow - Pinacate Lava Flow -
Around Aberdeen, lava flows from diverse vents form a large field with aa and pahoehoe forms [11] and neatly preserved surface features. [9] Lava flows reach lengths of 9 kilometres (5.6 mi) [3] and have thicknesses of 0.01–30 metres (0.39 in – 98 ft 5.10 in) and sometimes lava flows from separate cones overlap, such as in Papoose Canyon.

Euro News reported Monday a nearly 2-mile river of lava is flowing out of the crater, which is at an altitude of nearly 10,000 feet and that all hiking activities have been banned near the volcano.
Following a major earthquake swarm, multiple lava fountain eruptions began in Holuhraun. [39] The lava flow rate was between 250 and 350 m 3 /s (8,800 and 12,400 cu ft/s) and came from a dyke over 40 km (25 mi) long. [40] [41] An ice-filled subsidence bowl over 100 km 2 (39 sq mi) in area and up to 65 m (213 ft) deep formed as well. [37]
Kilauea, one of the world's most active volcanoes, began erupting around 2:30 a.m. local time, according to the U.S. Geological Survey.
