Which volcanic hazard occurs when melted snow or excessive rain mixes with volcanic sediments?
This can create volcanic mudflows called lahars.
What volcanic hazard is made up of rocky particles about the size of a grain of sand?
Pyroclastic fall is the volcanic hazard made up of rocky particles about the size of a grain of sand. These particles are ejected during an explosive eruption and can pose a threat to both life and property.
What volcanic hazard is made up of rocky particles about the size of sand?
Pyroclastic fall is a volcanic hazard made up of rocky particles about the size of sand. These particles are ejected during explosive volcanic eruptions and can be carried for long distances by the wind, posing a threat to both life and property.
What type of volcano hazard is made up of rocky particles about the size of grains of sand?
Volcanic ash is a type of volcanic hazard made up of rocky particles about the size of grains of sand. Ash can be very harmful to human health and can cause damage to infrastructure and agriculture.
Which volcano hazard is made up of rocky particles about the size of a grain of sand?
Volcanic Ash.
What is the main purpose of the article Hazard-Zone Maps and Volcanic Risk?
The main purpose of the article "Hazard-Zone Maps and Volcanic Risk" is to outline the importance of hazard-zone maps in assessing volcanic risks. It discusses how these maps help identify areas vulnerable to volcanic hazards, aid in disaster planning and management, and inform decision-making processes to mitigate volcanic risks.
Which volcanic hazard is the leading cause of death?
gases?

What is the main hazard from a quiet volcanic eruption?
it could be gas or just few rocks.
Which volcano hazard is made up of rocky particles about the size of a grain of sand?
Volcanic Ash.
Is a lahar a primary or secondary hazard?
A lahar is considered a secondary hazard. It occurs as a result of volcanic activity, specifically when volcanic ash and debris mix with water from rainfall or melting snow, leading to fast-moving flows of mud and debris down volcanic slopes. While it is triggered by primary volcanic events, such as eruptions, the lahar itself is a secondary phenomenon that poses significant risks to nearby communities and landscapes.
What are the two restricted sea areas in Montserrat?
The two restricted sea areas in Montserrat are the Exclusion Zone and the Volcanic Hazard Zone. The Exclusion Zone surrounds the Soufrière Hills volcano, where access is heavily restricted due to the risk of volcanic activity. The Volcanic Hazard Zone extends beyond the Exclusion Zone and includes areas that may be affected by ashfall, pyroclastic flows, and other volcanic hazards. These restrictions are in place to ensure public safety in light of the ongoing volcanic activity.
What Volcanic hazard occurs when melted snow or excessive rain mixes with volcanic sediments?
The volcanic hazard that occurs when melted snow or excessive rain mixes with volcanic sediments is called a lahar. Lahars are destructive volcanic mudflows that can flow rapidly down river valleys, carrying ash, rocks, and debris, which can bury structures, disrupt ecosystems, and pose significant threats to communities located near volcanoes. They can occur suddenly and often without warning, making them particularly dangerous.
What is the name of volcanic dust made into mud by rainfall?
The name for volcanic dust that is turned into mud by rainfall is "lahar." Lahars are fast-flowing mixtures of volcanic debris and water that can travel down the slopes of volcanoes, posing a significant hazard to surrounding communities.
