Evolution of Hawaiian volcanoes. 3-D perspective view of the southeastern Hawaiian Islands, with the white summits of Mauna Loa (4,170 m or 13,680 ft high) and Mauna Kea (4,206 m or 13,799 ft high) The evolution of Hawaiian volcanoes occurs in several stages of growth and decline. The fifteen volcanoes that make up the eight principal islands ...
Hawaiʻi Volcanoes National Park is a national park of the United States located in Hawaii on the island of Hawaii. The park encompasses two active volcanoes: Kīlauea, one of the world's most active volcanoes, and Mauna Loa, the world's largest shield volcano. The park provides scientists with insight into the development of the Hawaiian ...
Last eruption. September 15, 2024 – present. Kīlauea (US: / ˌkɪləˈweɪə / KIL-ə-WAY-ə, Hawaiian: [kiːlɐwˈwɛjə]) is an active shield volcano in the Hawaiian Islands. It is located along the southeastern shore of Hawaii Island. The volcano is between 210,000 and 280,000 years old and grew above sea level about 100,000 years ago.
The Hawaiian–Emperor seamount chain is a series of volcanoes and seamounts extending about 6,200 km (3,900 mi) across the Pacific Ocean. [ n 1 ] The chain was produced by the movement of the ocean crust over the Hawaiʻi hotspot , an upwelling of hot rock from the Earth's mantle .
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]
Honolulu Volcanics. The Honolulu Volcanics are a group of volcanoes which form a volcanic field on the island of Oʻahu, Hawaiʻi, more specifically in that island's southeastern sector and in the city of Honolulu from Pearl Harbor to the Mokapu Peninsula. It is part of the rejuvenated stage of Hawaiian volcanic activity, which occurred after ...
1968. Diamond Head is a volcanic tuff cone on the Hawaiian island of Oʻahu. It is known to Hawaiians as Lēʻahi (pronounced [leːˈʔɐhi]), which is most likely derived from lae (browridge, promontory) plus ʻahi (tuna) because the shape of the ridgeline resembles the shape of a tuna 's dorsal fin. [3]
Māhukona is a submerged shield volcano on the northwestern flank of the Island of Hawaiʻi. A drowned coral reef at about 3,770 feet (-1,150 m) below sea level and a major break in slope at about 4,400 feet (-1,340 m) below sea level represent old shorelines. A roughly circular caldera marks its summit. A prominent rift zone extends to the west.
