Hawaii is the most noted example of hotspot volcanism.
Kilauea is one of the most active volcanoes in the world....Kilauea is one of the world's most active volcanoes.
The volcano has been in constant eruption since 1983.
A large collapse occurred at Kilauea volcano in November 2005.....Mauna Loa volcano is one of the tallest mountains in the world. When measured from its base
on the sea floor, it rises more than 17,000 m (56,000 feet),....Hualalai is the westermost shield volcano on the island of Hawaii.
Eruptions of Hualalai Volcano in 1800-01 occurred from 5 vents with two lava flows reaching the sea.....Kohala is the oldest volcano in the Big island of Hawaii.
The most recent eruption was about 120,000 years ago.
The summit is broad and covered with trees.
.....Loihi is the youngest of the Hawaiian volcanoes.
It is located 35 km SE of the big island of Hawaii........Stage 1: InitialInitial eruptions of lava onto the ocean floor. Formation of pillow lava. Volcano may have steep slopes up to 45 deg. Example - Loihi volcano (late stage 1).
Stage 2a: Shield Building - submarineRepeated voluminous eruptions of pillow lava. volcano slopes 10-20 deg. No explosive activity due to water pressure.
Stage 2b: Shield Building - sea levelVolcano reaches surface with boiling water, explosive eruptions and fracturing of tephra to form an island.
Stage 2c: Shield Building - subarialPermanent island formation. Central and rift eruptions. Volcano slope of 3-10 deg formed by Pahoehoe and Aa lava flows. Calderas and pit craters form and fill repeatedly. Only a small percentage of tephra forms the volcano. Continued submarine and sea level eruptions expand the volcano outwards. Examples are Kilauea and Mauna Loa volcanoes.
Stage 3: CappingExplosive eruptions become more common due to formation of more viscous lava. Steep cap with a slope up to 20 deg is formed over the shield volcano. Eruptions become separated by longer time intervals and finally end. Example - Hualalai volcano. Mauna Kea volcano (very late stage 3).
Stage 4: ErosionalThe dominant process is erosion by streams and waves. Canyons, valleys and seacliffs form. Corals grow in shallow water around the island.
Stage 5: Renewed VolcanismRenewed volcanism may occur after hundreds of thousands or millions of years. Erosion and reef building continue.
Stage 6: AtollThe volcano eventually erodes to sea level forming a flat island surrounded by coral reef.
Stage 7: Late SeamountErosion overtakes reef building and the island sinks below ocean surface.
