No. Lava flows usually move rather slowly, giving time to evacuate. The deadliest volcanic hazard is the pyroclastic flow. These are avalanche-like clouds of ash, rock, and gas that race down the sides of a volcano, burning everything in their path. Many people have been killed by ash, either by suffocating or from collapsing roofs. Many people have been killed by muflows called lahars that form when water from rain or melting ice mixes with volcanic ash. In 1883 tens of thousands were killed by tsunamis triggered when the island of Krakatoa collapsed in a cataclysmic eruption.

What are major hazards associated with volcanic eruptions?
Most deaths during eruptions occur during pyroclastic flows/surges during an eruption and volcanic mudslides (known as lahars) after the eruption.
Is it True or false volcanic eruptions cause damage only when they are close to the craters rim?
False. Volcanic eruptions can cause damage beyond the crater's rim. Lava flows, pyroclastic flows, ashfall, volcanic gases, and lahars (volcanic mudflows) can all pose hazards and cause damage far beyond the immediate vicinity of the volcano. The extent of damage depends on the size and intensity of the eruption, as well as topography and prevailing wind patterns.
Which volcanic hazards are Vesuvius likely to produce?
It is likely to produce pyroclastic flows which are cascades of very hot ash, dust gas and boulders. As well as volcanic bombs
Can volcanic eruption and seismic tremors produce large mudflows and debris flows?
Yes. Earthquakes and volcanic eruptions can cause debris flows. Volcanic eruptions can mudflows called lahars.
What are three hazards of volcanoes?
3 hazards of a volcanic eruption are.... - lava flows - clouds of ash - hot volcanic ashes
What are some hazards of volcanic eruptions?
lava flows clouds of ash hot volcanic gases landslides avalanches of mud snow and rock

Why are lava flows not deadly?
Lava flows are generally slow moving, giving people time to evacuate. As a result, they do not kill as often as other volcanic hazards such as pyroclastic flows.

Can volcanic eruption and seismic tremors produce large mudflows and debris flows?
Yes. Earthquakes and volcanic eruptions can cause debris flows. Volcanic eruptions can mudflows called lahars.
Why are lava flows usually of less immediate danger to humans beings than some other volcanic hazards?
Volcanos erupt

How topography influences volcanic flows?
explain how topography influences volcanic flows
What are some less hazards from volcanic eruption?
The only effective method of risk mitigation is evacuation prior to such eruption from areas likely to be affected by pyroclastic flows. 5 - Lahars ( volcanic mud and debris flows) are a common major volcanic hazard for people and property. Laharslikewise proceed very quicky and possess great destructive power.
Identify thre ahzards of volcanic eruptions?
A volcanic eruption is a beautiful and terrifying phenomenon. The key hazards are the gasses which can cause suffocation, earthquakes, ash deposition, and pyroclastic flows. A pyroclastic flow is the cascading of quantities of often superheated ash, rock, mud, and other material from the sides of a volcano itself at great speed and force.
