The primary hazards involve lava, gases, and pressure.
A quiet volcanic eruption can release poisonous gases (such as sulfur compounds) which can poison the air or water supplies. Also, lava flows can create dangerous wildfires, and destabilize slopes leading to landslides. Additionally, they can add stress to underground rock formations and potentially trigger earthquakes.
Mount Pinatubo in the Philippines has a vent known as a caldera, which is a large volcanic crater formed by the collapse of land following a volcanic eruption. So technically, it has one main vent - the caldera formed after the 1991 eruption.
Height of the main vent of the volcano
The silica content effects the force of a volcanic eruption because magma with a lot of silica is thicker and magma with less silica is thinner. The amount of dissolved gases in magma effects the force of a volcanic eruption because the less gas in the magma, the less pressure will be inside the volcano. The temperature of the magma effects the force of a volcanic eruption because the hotter the magma, the more runny it is.
The main hazards from an explosive volcanic eruption include pyroclastic flows, which are fast-moving currents of hot gas and volcanic material that can devastate everything in their path; ash fall, which can cause respiratory problems, collapse buildings, and disrupt air travel; and volcanic blasts that can produce shock waves and ballistic projectiles. Additionally, lahars, or volcanic mudflows, can occur when volcanic materials mix with water, posing significant risks to communities downstream. These hazards can lead to loss of life, destruction of infrastructure, and long-term environmental impacts.
Yes, Santorini is a volcanic island known for its geological formations created by past volcanic activity. The island's main feature is the caldera, a large submerged volcanic crater, which was formed by a massive volcanic eruption in the Bronze Age.
it could be gas or just few rocks.
quiet ,and explosive eruptions

The main theory was that it was the workings of the gods.

why do you have to use answers you stupid person who ever you are get a life get a job don't quit school you should know this already
earthquakes pressurize the main magma chamber in a volcano by the earth crust. as a result the magma comes out of the volcano
