Basaltic magma allows dissolved gases to bubble upward and escape
Hawaii has lots of volcano eruptions, volcanoes can also erupt on tropical islands.
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.
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.
The island of Hawaii was formed by volcanic activity over a period of thousands of years.

Basaltic
Yes!
Yes, you can actually.

Basalt volcanoes are referred to as shield volcanoes. Volcanoes of this type include Mauna Loa and Kilauea, both in Hawaii.

they create new land. For example Hawaii. The eruptions can cause tsunamis
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
A volcano is a landform, not an event. There have been many volcanic eruptions of several volcanoes in Hawaii in recorded history.
