The three main factors that affect the force of a volcanic eruption are the viscosity of the magma (more viscous magma results in more explosive eruptions), the amount of gas dissolved in the magma (higher gas content leads to more explosive eruptions), and the presence of a plug in the volcanic vent which can build up pressure and lead to a more violent eruption.
The three main causes of volcanic eruptions are the accumulation of magma beneath the Earth's crust, the buildup of pressure within the magma chamber, and the release of gases trapped in the magma. These factors can lead to explosive eruptions that result in the expulsion of ash, lava, and volcanic gases.
Major hazards associated with volcanic eruptions include pyroclastic flows, which are fast-moving currents of hot gas and rock that can destroy everything in their path; ash clouds that can disrupt air travel and cause respiratory issues; lahars, which are fast-moving mudflows of volcanic ash and debris; and lava flows which can destroy structures and infrastructure.
Krakatoa had an explosive eruption in 1883. It was one of the most powerful volcanic explosions in recorded history, resulting in devastating tsunamis, ash clouds that circled the Earth, and a significant decrease in global temperatures.
Two types of volcanic eruptions are explosive eruptions, characterized by the violent ejection of lava, ash, and gases, and effusive eruptions, which involve the slow release of lava flows. Explosive eruptions are typically more destructive and can create volcanic ash clouds that pose hazards to aviation and human health. Effusive eruptions, on the other hand, can lead to the formation of lava plateaus and shield volcanoes.
quiet ,and explosive eruptions
The main product of an explosive eruption is ash, which consists of tiny rock fragments and volcanic glass. Ash can be carried long distances by wind and poses a hazard to aircraft engines and respiratory systems. In addition to ash, explosive eruptions can also produce gases, such as sulfur dioxide and carbon dioxide, which can contribute to air pollution and climate change.

it could be gas or just few rocks.

The main cause of differences in volcanic eruption characteristics is due to the viscosity of the magma. High viscosity magmas are high in sticky silica which traps gas and produces explosive eruptions. Low viscosity magmas are low in silica and produce eruptions with far less energetic characteristics.

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.
