Hawaii hotspot
Hawaiian volcanoes are characterized by frequent rift eruptions, their large size (thousands of cubic kilometers in volume), and their rough, decentralized shape. Rift zones are a prominent feature on these volcanoes, and account for their seemingly random volcanic structure. The tallest mountain in the Hawaii chain, Mauna Kea, rises above mean sea level. Measured from its base on the seafloor, it is the world's tallest mountain, at ; Mount Everest rises above sea level. Hawaii is surrounded by a myriad of seamounts; however, they were found to be unconnected to the hotspot and its volcanism. Kīlauea has erupted continuously since 1983 through Puʻu ʻŌʻō, a minor volcanic cone, which has become an attraction for volcanologists and tourists alike.
Mount Kerinci
At 3,805 meters above sea level, Kerinci is the highest volcano in Indonesia. Also, Kerinci making Sumatra fifth highest island and rank first in Asia both the highest volcano in an island and highest island highpoint made of volcano; but in second rank in world in both terms after Mauna Kea of Hawaii island. Kerinci is located in the border of the titular Kerinci Regency of Jambi province and South Solok Regency of West Sumatra province, in the west central part of the island near the west coast, and is about south of Padang. It is part of the Barisan Mountains, a chain of volcanoes that span from the extreme northwest of the island (in Aceh province) all the way to the extreme southeast (in Lampung province). It is the most prominent feature of the terrain of Kerinci Seblat National Park, with pine-forested slopes rising 2,400-3,300 metres above the surrounding basin, and a cone wide and long at the base, elongated in the north-south direction. At the summit there is a deep wide crater, often partially filled by a small crater lake on the northeast side of the crater floor.
