The volcanoes of Hawaii form fron thin basaltic magma that tends to erupt quietly What is one reason for the quiet eruptions?

Volcanoes and their places?
Hawaii has lots of volcano eruptions, volcanoes can also erupt on tropical islands.
Why are volcanoes in Hawaii the least severe?
The volcanoes in Hawaii erupt basaltic lava, which is relatively runny and has a low gas content. As a result the volcanoes usually produce effusive eruptions; fountain or oozing lava but rarely producing explosions. After emerging the lava travels along as fairly slow-moving lava flows. These flows can be destructive, but are easy to escape.
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 forms the islands of Hawaii?
The island of Hawaii was formed by volcanic activity over a period of thousands of years.
Which volcanoes form from extensive fluid lava form that erupts numerous times?
A+ Shield
What is the source of the magma in Hawaii's volcanoes?
Basaltic
Is Lava flowing from volcanoes in Hawaii basaltic magma.?
Yes!
Can you find lots of basaltic volcanoes in Hawaii and Iceland?
Yes, you can actually.

Submerged basaltic volcanoes that are higher than 1 km are called?
Basalt volcanoes are referred to as shield volcanoes. Volcanoes of this type include Mauna Loa and Kilauea, both in Hawaii.

Describe one benefit of volcanoes and one danger volcanoes pose?
they create new land. For example Hawaii. The eruptions can cause tsunamis
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
What year did the Hawaii Volcano take place?
A volcano is a landform, not an event. There have been many volcanic eruptions of several volcanoes in Hawaii in recorded history.
What forms the islands of Hawaii?
The island of Hawaii was formed by volcanic activity over a period of thousands of years.
Which volcanoes form from extensive fluid lava form that erupts numerous times?
A+ Shield
