Like all Hawaiian volcanoes, Mauna Loa was created as the Pacific tectonic plate moved over the Hawaii hotspot in the Earth's underlying mantle. [10] The Hawaii island volcanoes are the most recent evidence of this process that, over 70 million years, has created the 3,700 mi (6,000 km)-long Hawaiian–Emperor seamount chain. [11]
The 1868 Hawaiʻi earthquake was the largest recorded in the history of Hawaiʻi island, [3] with an estimated magnitude of 7.9 Mfa[1] and a maximum Mercalli intensity of X (Extreme). The earthquake occurred at 4 p.m. local time on April 2, 1868, and caused a landslide and tsunami that led to 77 deaths. The aftershock sequence for this event ...
Kohala (mountain) Kohala is the oldest of five volcanoes that make up the island of Hawaii. Kohala is an estimated one million years old—so old that it experienced, and recorded, the reversal of Earth's magnetic field 780,000 years ago. It is believed to have breached sea level more than 500,000 years ago [1] and to have last erupted 120,000 ...
Why the Mauna Loa Eruption Is a Scientific Bounty Andrew Richard Hara - Getty Images. The world’s largest volcano has erupted for the first time since 1984, and it could prove a scientific bounty.
Geology. Age of rock. Pleistocene epoch. Mountain type. Shield volcano. Volcanic arc / belt. Hawaiian-Emperor seamount chain. West Molokai Volcano, sometimes called Mauna Loa for the census-designated place, is an extinct shield volcano comprising the western half of Molokai island in the U.S. state of Hawaii.
Hawaiian eruption. A Hawaiian eruption is a type of volcanic eruption where lava flows from the vent in a relatively gentle, low level eruption; it is so named because it is characteristic of Hawaiian volcanoes. Typically they are effusive eruptions, with basaltic magmas of low viscosity, low content of gases, and high temperature at the vent.
Chain of Craters Road is a 19-mile (31 km) long winding paved road through the East Rift and coastal area of the Hawaii Volcanoes National Park on the island of Hawaii, in the state of Hawaii, United States. The original road, built in 1928, connected Crater Rim Drive to Makaopuhi Crater. The road was lengthened to reach the tiny town of ...
