Hawaiian Erupt
Hawaiian eruptions are less viscus, therefore the lava travels further and affects more people

Strombolian Eruptions
Strombolian eruptions normally have often small lakes of lava. Strombolian eruptions are one of the least violent eruptions to happen, but still very dangerous next to bombs or lakes of lava. Strombolian was named after an Italian island called Stromboli which has several erupting summit vents. The Strombolian eruptions are beautiful at night.
This kind of eruption can create types of eruptive products like spatter or hardened chunks of blobs of glassy lava, which are hardened chunks of lava, the tape of eruption causes small lava flows.
Strombolian eruptions are distinct bursts of fluid lava it comes from the mouth of a magma-filled summit conduit. The explosions usually happens every few minutes at regular or irregular intervals. These explosions of lava can reach heights of hundreds of meters. This happens because of the bursting of large bubbles of gas. They go upward into the magma-filled conduit until they reach the open air.

Vulcanian Eruption
The volcanium eruption is a small explosion of magma it can last days, months or even years. The lava can travel 350 meters per second and rise far into the air. It was named after a italian island called "Vulcano" where a small volcano experienced this type of eruption. this eruption is formed by lava that piles up on the vent. It is a Dome volcano.

Plinian eruptions are the largest and most violent of all the types of volcanic eruptions. they are caused by fragmentation of gases and magma. The ash can rise up to 50 km at high speeds. It creates a mushroom cloud similar to a nuclear bomb. These eruptions are so powerful that they can even come to destroy the top of the mountain.
Lava Domes
First of all imagine when you squeeze a toothpaste package, when it you squeeze it, the toothpaste comes out. Now imagine the some thing in a dome volcano. This type of volcano erupts when the lava is squeezed inside it's vent. but instead of toothpaste it works with lava lobes. Also instead of the volcano erupting with explosion, the lava is squeezed comes out. Lava lobes are formed ''when very viscous, rubbly lava (usually andesite, dacite or rhyolite)'' and it's squeezed out of the vent without exploding.

The dome volcano is not to be confused as
a pile of rocks the dome volcano has some large eruption.the eruption can destroy its selve
Surtseyan Eruption
Surtseyan eruptions are when magma or lava explosively react to water it usually occur when a underwater volcano erupts.water expands into steam,
when water comes with contact with hot lava it creates plumes
Of ash,steam and scoria.
-
The onshore and offshore explosions created plumes of ash and steam that rose to more than 8 km (5 miles) altitude, and threw plumes of tephra hundreds of meters from the vents.
-
surtseyan eruption are a kind of Hydromagmatic eruption. hydromagmatic activity built up several square kilometers of tephra over the first several months of the eruption.
The classic example of a Surtseyan eruption was the volcanic island of Surtsey, which erupted off the south coast of Iceland between 1963 and 1965.
