The Effects of Volcano Eruptions. The lava flow can also For example, the recovery time of ocean heat content of Pinatubo , which caused comparable radiative forcing to Krakatau, seems to be much shorter. It reduces the isolation of sunlight. To make matters worse the problem has not gotten better. Mount Sinabung, Jakarta, Indonesia erupted with plumes of ash spewed more than one mile into the sky. Poisonous gases are usually released during volcanic eruptions. Volcanoes attract many tourists, who enjoy the dramatic scenery that they produce. The lava flow and mud-flows caused by volcanic eruptions can kill people and destroy property as it moves rapidly down the side of the volcano. They can kill people and damage property. That is because the ash spewed by a volcano can negatively affect the engines in an aircraft. Once these particles are ready to fall out of the atmosphere they start descending through the rain, which usually occurs within a few hours or days after the eruption. Ash and mud can mix with rain and melting snow, forming lahars. Mount Sinabung, Jakarta, Indonesia erupted with plumes of ash spewed more than one mile into the sky. Therefore, because hot dust many plants die. Ash ejected by the volcano acts as a good fertiliser for soils. They can cause rain, thunder, and lightning. Let us see some negative effects of volcanoes: Eruptions occurring close to human settlements may spill and destroy lives and property. They may occur with or without an eruption.

These nutrients are very beneficial for agriculture. Volcanoes have a large effect on their locality. These enormous and menacing clouds are often accompanied by thunder and lightning. The animals aren't as effected because the lava flow is slow enough everyone should be able to get away in time. Negative Effects of Volcanic Eruptions Widespread damage: All volcanic eruptions result in widespread damage to the point that whole cities are destroyed along with the entire local infrastructure. Positive effects of volcanic eruption: Fertile soil: When volcanoes explode they bring with them nutrients from the ground. People have died from volcanic blasts. Negative Effects: • Lahars •Nuée Ardentes •Loss of Life •Damage to Property •Effects the Environment . This can also trigger flash floods, and rock fall. Different types of erupting volcanoes provide extraordinary scenery, so beautiful and natural that they attract tourists to the area, bringing in some economic value.

When Lava comes out from the volcano, that will flow down the stream and burn living and non-living things those come in the way. Those affected were within a 3-kilometer radius of the volcano. Another benefits to volcanoes are the precious gems, minerals and building materials that eruptions make available. Composite and shield volcanoes are found along plate margins. Unlike other natural disasters such as floods, wildfires, and earthquakes, volcanoes can have some positive effects, even though they can be very disastrous. First, when the eruption comes, it will definitely lot of bodies down over this disaster. While the ocean volcano erupts, it will be a lot of negative effects will occur. The hot lava together with ash destroys not only human beings but also plant and animal life. Volcanic lightning is a unique phenomenon and scientists continue to debate the way it works.
