- Mauna Kea has 6 known eruptions during Holocene times. The most recent was approximately 2460 BCE and the earliest known eruption of Holocene time was approximately 5150 BCE. … The length of time between eruptions has drasticly increased due to the waning activity from this volcano. Mauna Kea with its most recent eruption roughly 4,500 years ago is in the post-shield stage of development, which is characterized by more explosive and infrequent eruptions from the volcano. Although the eruptions are explosive in nature they are often times very small and short lived. 1 person found this useful.

10 Surprising Facts About the 1984 Mauna Loa Eruption Double Rainbow Eruption: Nearly a week into Mauna Loa’s eruption, another Hawai’i volcano decided to follow suit. On Friday, March 30, 1984, the smaller Kilauea volcano started erupting within the confines of Hawai’i Volcanoes National Park, marking the first double-eruption in almost 116 years! 7. Did You Call?: Once the news had spread that Mauna Loa was erupting, HVO “was besieged” with phone calls, according to then-Mauna Loa geologist Jack Lockwood.

Mauna Kea Mauna Kea, is a dormant volcano on the island of Hawaii. Standing 4,207 m above sea level, its peak is the highest point in the state of Hawaii. Most of the mountain is underwater; when measured from its oceanic base, Mauna Kea is over 10,000 m tall and is the tallest mountain on Earth. Mauna Kea is about a million years old, and has thus passed the most active shield stage of life hundreds of thousands of years ago. In its current post-shield state, its lava is more viscous, resulting in a stee

General Info Mauna Loa has erupted 33 times since 1843 (with other less well-dated eruptions going back to 1832 and before). These historical flows cover 806 km of the volcano's surface. Typically, these eruptions began in the summit caldera, Moku'aweoweo, with a curtain of fire (which is a 1 to 2 km line of lava fountains).Eruptions may consist solely of summit activity or they progress down-flank via rift zone dike propagation (in the subsurface) to feed flank vents.ypically, these eruptions began in the summit caldera, Moku'aweoweo, with a curtain of fire (which is a 1 to 2 km line of lava fountains).

Earth's Largest Active Volcano Since 1200 CE, roughly the past 700 years, eruptions occurred primarily from vents located on Mauna Loa's rift zones. Before about 700 years ago back to 200 BCE, lava was erupted primarily from the summit area onto the west, north, and east flanks of the volcano with flows reaching the sea.

What are the active volcanoes in Hawaii and what is their status? For example, the current eruption started in January of 1983 and has been continuous ever since! Likewise, there was an active lava lake in the summit caldera from at least 1823 until 1924, while at the same time eruptions would take place elsewhere on the flanks of the volcano. Mauna Loa is an active volcano and is due for an eruption. Mauna Loa has erupted 15 times since 1900. These eruptions have lasted from a few hours to 145 days. Since 1950 Mauna Loa has erupted only twice, in 1975 and 1984. The 1975 eruption lasted 1 day. The 1984 eruption lasted 3 weeks.

The most recent eruption in 1984 lasted 22 days and produced lava flows which reached to within about 7.2 km (4.5 miles) of Hilo, the largest population center on the Island of Hawai‘i. Lava flows less than 4,000 years old cover about 90 percent of the volcano. Hualālai, the third most active volcano on the Island of Hawai‘i, has erupted three times in the past 1,000 years and eight times in the past 1,500 years.
