The Hawaiian volcanoes are giant shield volcanoes. They
have formed over a stationary hot spot in the middle of the Pacific
Plate. The tops of some of the volcanoes are tall enough to form islands that are above the surface of the ocean. The state of Hawaii consists of
eight main islands and an archipelago that stretches 1600 miles in

Tallest volcanic mountains in Pacific Ocean
The Big Island of Hawaii was created by five volcanoes: Mauna Kea, Mauna Loa, Kilauea, Kohala Volcano and Hualalai Volcano.The tallest volcanoes in the Pacific Ocean are Mauna Kea and Mauna Loa.
Total height of Mauna Kea
Mauna Kea is the tallest volcano in the Hawaiian chain. It is 4,207 m (13,796 ft) above sea level. Measuring Mauna Kea from its base on the ocean floor to its summit the volcano is 10,000 m (33,000 ft) tall.
Mount Everest is on land. Its height is measured from its base to the summit. Mount Everest is 8848 m (29,029 ft.) tall. Comparing the total heights of the two mountains Mauna Kea is 1,152 m taller than Mount Everest
Mauna Loa volcano
Mauna Loa is not as tall as Mauna Kea. Mauna Loa measured at sea level is 4169 m (13,679 ft.) tall. Mauna Loa is the largest volcano on Earth in terms of volume and area covered. The volcano's estimated volume is 75,000 cubic meters (18,000 cubic miles). The volcano is still active and there have been 33 eruptions since 1843.
1984 eruption of Mauna Loa
The last eruption in 1984 stopped just a few miles short of Hilo, Hawaii. The volcano does not erupt as often as Kilauea but when it erupts the volume is much greater. During the last eruption in 1843 the volcano spewed out more lava that Kilauea usually produces in three years and came within a short distance to Hilo.
Kilauea is one of the most active volcanoes on our planet. The volcano began the longest rift-zone eruption in historic times on January 3, 1983. Lava fountains formed in the rift zone about ten miles below the summit caldera. Powerful eruptions threw molten rock high in the air building a cinder cone.
New vent forms on volcano
A new vent in 1986 created a lava lake on top of a small shield volcano. The small shield continued to increase in size and was about 180 feet tall and 4800 feet at its base by 1991.
May 3, 2018 - September 4, 2018
Kilauea East rift-zone began an eruption on May 3, 2018 the eruption produced lava flows, lava fountains from an elongated fissure that had from 16- 20 channels that molten lava flowed over the landscape. Thousands had to evacuate the area during the eruption that destroyed houses, roads and utilities. The eruption stopped on September 4, 2018.

You will find a number of websites with information about the volcanoes. The addresses change without notice so you need to go to your favorite search engine to find the latest activity.
Hualalai Volcano is the third most active Hawaiian volcano and is located on the Kona side of the Big Island. The last eruptions of the volcano was over 200 years ago. Two eruptions in 1800 and 1801 produced lava flows from the northwest rift zone. The Kona airport lies on top of one of these flows.
