The massive lava flow reached the Pacific Ocean at Kapoho Bay on June 4. [7] [8] Lava entered the Kapoho Crater and evaporated Green Lake, which had been the largest natural freshwater lake in Hawaiʻi. On the night of June 4–5, the northeastern flow of lava speedily moved forward and destroyed the subdivision of Vacationland Hawaii. [9]
The volcanic field consists of two lava flows, the Broken Back flow and the Carrizozo lava flow (Carrizozo Malpais), the second youngest in New Mexico. [5] Both lava flows originated from groups of cinder cones. The Broken Back flow is approximately 16 kilometres (10 mi) long and the Carrizozo, one of the largest in the world, is 68 kilometres ...
Lava flows from the Uinkaret volcanic field that have cascaded down into the Grand Canyon, damming the Colorado River, have been used to date the canyon's carving. [3] One of these cascades is today's Lava Falls. Lava Falls Rapid, below Lava Falls on the Colorado River, is "at all water levels, the most severe rapid in Grand Canyon." [4]
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 ...
The 2022 eruption of Mauna Loa was an episode of eruptive volcanic activity at Mauna Loa, the world's largest active volcano, located on Hawaiʻi island, Hawaiʻi.Mauna Loa began to erupt shortly before midnight HST on November 27, 2022, when lava flows emerged from fissure vents in Moku‘āweoweo (Mauna Loa's summit caldera).
The two main types of lava field structures are defined as sheet flow lava and pillow lava. Sheet flow lava appears like a wrinkled or folded sheet, while pillow lava is bulbous, and often looks like a pile of pillows atop one another. [2] An important aspect of lava flow morphology is a phenomenon known as lava flow inflation. This occurs in ...
The lava that flows in lava channels is commonly basaltic in composition. Pāhoehoe lava flow on the Big Island of Hawaii The picture shows overflows from a main lava channel. The channel is crusting over with a v-shaped opening pointing upstream (top left). The main channel and overflows show the perched nature of this kind of lava channel.
Effusive basalt lava flows cool to either of two forms, ʻaʻā or pāhoehoe. [8] This type of lava flow builds shield volcanoes, which are, for example, numerous in Hawaii, [9] and is how the island was and currently is being formed.
