Volcanic eruptions are caused by the movement of magma beneath the earth's crust, leading to pressure build-up and release through the volcano. Effects include ash clouds, pyroclastic flows, and lava flows that can damage property and endanger lives. Mitigation strategies include monitoring volcanic activity, creating exclusion zones, and implementing emergency preparedness plans to protect communities.
Pelean
Mount Pelee's magnitude refers to the Volcanic Explosivity Index (VEI) of its 1902 eruption, which was estimated to be a 4. This VEI level indicates a significant explosive eruption that can cause widespread destruction and has a global impact.
Volcanoes can have both positive and negative effects on soil. While volcanic eruptions can enrich the soil with minerals and nutrients, they can also cause soil degradation and infertility due to the deposition of ash and lava. The extent of the impact depends on the proximity to the volcano and the type of eruption.
Volcanoes erupt due to the buildup of pressure from molten rock, gas, and ash beneath the Earth's surface. During a volcanic eruption, kids should know that lava, ash, and gases are released, which can be dangerous and cause damage to the surrounding area. It is important for kids to understand evacuation procedures and to stay informed about volcanic activity in their area.
Ash released from a volcanic eruption can enter the upper atmosphere where it can reflect sunlight. Volcanoes formed the early atmosphere of the planet, so they definitely can have global impact, an increase in agriculture does not signify a significant change in global temperature.
No
Volcanic eruptions that cause more deaths typically have a combination of factors such as the size of the eruption, proximity of populated areas to the volcano, speed of the eruption, type of volcanic activity (explosive vs effusive), and effectiveness of hazard mitigation measures. The presence of pyroclastic flows, lahars, and ashfall can also significantly impact the number of casualties.
No. There is nothing any person can do to cause or prevent a volcanic eruption.
yes
A volcanic eruption can displace communities, disrupt livelihoods, and lead to long-term economic impacts in the affected region. It can also cause environmental damage, such as ash fall and contamination of water sources, which can have health implications for both humans and animals living in the area. Additionally, the social effects may include increased stress, anxiety, and trauma among the affected population.
volcanic eruptions may cause mass extinctions or volcanic haze.a mass extinction is when a large number of species die out over a short period of geologic time and volcanic haze is when the gases of an eruption cause a haze and block out sunshine, causing a mass extinction.
Plate tectonics
When tectonic plates go under each other.

Cows and volcanic eruption.
The deadliest volcanic eruption in the world was the eruption of the Tambora volcano in 1812, It caused an estimated 92,000 deaths.
A volcanic eruption can cause an earthquake and an earthquake underwater can cause a tsunami.
