Did Hawaiian volcano have the most explosive eruption?
No. Volcanic eruptions in Hawaii are not usually explosive.
What type of eruptions do mafic magmas cause?
Basaltic magmas are associated with fissure eruptions creating lava flows spilling out from cracks in the crust. This is because basaltic magmas are more viscous and contain a lower concentration of gases than rhyolitic magma and therefore are unable to build up sufficient pressure to produce explosive eruptions.
What types of volcanos are the result of non-explosive eruptionso like at Hawaii?
The types of volcanoes resulting from non-explosive eruptions, like those in Hawaii, are primarily shield volcanoes. These volcanoes are characterized by their broad, gently sloping profiles formed by the accumulation of low-viscosity basalt lava that can flow over long distances. The eruptions are typically effusive, allowing lava to flow steadily rather than explosively. This results in the creation of large, expansive landforms that are less steep compared to other volcanic types, such as stratovolcanoes.
Characteristics of kilauea volcano?
Kilauea volcano, located in Hawaii, is one of the most active volcanoes in the world. It has been continuously erupting since 1983. Kilauea has a shield-like shape, with gentle slopes formed by fluid lava flows. The volcano is known for both effusive (non-explosive) and explosive eruptions, with lava fountains and lava flows being common.
Why quiet eruptions on the Hawaiian islands?
Hawaii's volcanos are quite compared to Mt St Helens because Mt St Helens blew up from a earthquake of two plates shifting making the volcano vary voilent and loud which blew one half of the volcano
Is a Hawaiian volcano an explosive volcano?
Generally not. Most eruptions in Hawaii are effusive.

What is the most common VEI for volcanoes in Hawaii?
0 to 1, 0 being more common than 1. The reason is that Hawaiian volcanoes aren't very explosive. They produce a lot of lava, but with a continuous flow. VEI index measures explosiveness, with indicators for eruption column height and volume of pyroclastic material produced. Both factors are low for Hawaiian volcanoes.
Does volcanic ash increase Hawaii's land mass?
No. The volcanoes of Hawaii build up the land through lava flows. Explosive, ash-producing eruptions are rare there.
What is a volcano that may erupt explosively or non explosively?
One example of a volcano that can erupt explosively is Mount St. Helens in the United States. On the other hand, Kilauea in Hawaii is known for more frequent non-explosive eruptions characterized by effusive lava flows.
What are the eruptions in Hawaii like?
The eruptions in Hawaii are quiet eruptions coming from a hot spot.
Why does Kilauea have non-explosive eruptions?
Kilauea volcano in Hawaii has non-explosive eruptions because it mainly produces basaltic lava, which is low in silica content and has low viscosity. This allows gases to escape easily, preventing pressure build-up that leads to explosive eruptions. Instead, lava flows steadily from the vent, creating lava fountains or flows.
What is Kilauea's structure?
Kilauea is a shield volcano, characterized by gentle sloping sides formed by successive lava flows. It is one of the most active volcanoes in the world and is located on the southeastern side of the Big Island of Hawaii. Kilauea's structure is influenced by its eruptive behavior, which includes both effusive lava flows and explosive eruptions.
Why does Hawaii experience volcanic eruptions?
as they are sitting on the hot spot (which is a place were the magma sits just under the crust of the earth) causing a trail of volcanic eruptions as the contanetal plate moves over it
