What is wetter lahars or pyroclastic flows?
Lahars are wet. They are mudflows that result from volcanic ash mixing with water. Pyroclastic flows are superheated clouds of ash and gas that move down the slopes of a volcano. They are too hot to be wet.
Can mud flows and lahars be prevented?
Mudflows and lahars can be prevented or greatly reduced by planting deep rooted vegetation in places they might occur.
Why are snow covered volcanoes particulary dangerous?
Snow covered volcanoes are particularly dangerous because the snow can melt quickly during an eruption, leading to devastating mudflows known as lahars. The combination of hot volcanic materials mixing with water from melting snow can create fast-moving lahars that can travel long distances, causing widespread destruction. Additionally, the presence of snow can mask signs of an impending eruption, making it difficult to predict and evacuate in time.
Which is not an example of intrusive activity sills and dikes laccoliths lahars Batholiths?
Lahars are not examples of intrusive activity. Lahars are fast-flowing mixtures of water, rock debris, and volcanic ash that move down the slopes of a volcano during an eruption or due to melting snow and ice. Intrusive activities include the formation of sills, dikes, laccoliths, and batholiths, which involve the movement of magma into Earth's crust.
What kind of volcano produce lahar?
Lahars are mainly produced by stratovolcanoes, which are tall, steep-sided volcanoes composed of layers of hardened lava, ash, and volcanic rocks. These volcanoes are prone to explosive eruptions that can melt snow and ice, triggering lahars when the volcanic material mixes with water and flows down the volcano slopes.
What is wetter lahars or pyroclastic flows?
Lahars are wet. They are mudflows that result from volcanic ash mixing with water. Pyroclastic flows are superheated clouds of ash and gas that move down the slopes of a volcano. They are too hot to be wet.
Are lahars examples of intrusive igneous activity?
No. Lahars are the result of extrusive activity.
Can tall structures prevent volanoes and lahars?
No. Tall structures will not affect volcanoes. Dams can potentially mitigate lahars.
Why did people die in laki eruption in Europe?
because of pyroclastic flow (mixture of hot gas and rock), molten rocks(volcanic bombs) or lahars (volcanic mud flow)
Can mud flows and lahars be prevented?
Mudflows and lahars can be prevented or greatly reduced by planting deep rooted vegetation in places they might occur.
What are mudslides produced by volcanoes called?
Lahars

Does a lahar come out of an earthquake?
No. Lahars are mudflows that are produced by volcanoes.
Are lahars dangerous?
Yes they are dangerous as the water can flood buildings

What are mount rainiers eruption hazards?
pyroclastic flows, ash, and lahars
Are lahars and volcanoes alike?
No. A lahar is a mudflow composed of volcanic material.
