Halaie essays

Halaie essays Halalai is the third youngest and third most historically active volcano on the island of Hawaii. Six different vents erupted lava. Two of the vents generated lava flow into the West Coast of the island. Halalai is shield volcano. The summit of Halalai rises to an elevation of 2523m (8271ft) above sea level. The volcano is the westernmost of the five major Hawaii volcanoes. It has a well-developed northwestern rift zone, a moderately well developed South-Southeastern rift zone, and a poorly developed North rift zone. The most recent eruption of 1800-1801occurred along the Northwest rift zone. The volcano is has completed its main Tholeiitic Shield Stage. Its oldest rock dates back to about 128,000 years before present. The estimated age of Halalai apparently grew above sea level before 300,000 years ago. Although it has been 200 years since the last eruption of Halalai, it will most certainly erupt again. The last historical eruption on Halalai ended in 1801. This eruption produced very fluid, high velocity flows that entered the ocean off western Hawaii. Halalai rarely erupts, but is still an active volcano. It is also considered dangerous. Rubin, Ken.
