What is 500?
A volcano that has 'recently' erupted is
What is active?
Volcanoes form on what part of Earth's crust
What are tectonic plates?
This fluid emerges rapidly when a volcano erupts
What is lava?
The most active volcano is located in this state
What is Hawaii?
The highest population densities at risk are in these two regions of the world
What are south-east Asia and Central America?
An active volcano that has not recently erupted is
What is dormant?
This is the fluid material that volcanoes are formed from
What is magma?
Dangerous clouds of hot gases and materials such as volcanic fragments, crystals, ash, pumice and glass shards
What is pyroclastic flow?
Most volcanoes in the US are located in this state
What is Alaska?
Indonesia is located at the junction of this number of tectonic plates
What is three?
A volcano that is not likely to erupt again is
What is extinct?
This type of volcano is located in the zones of the Earth’s crust where one tectonic plate is thrust and consumed beneath another
What is a subduction volcano
This volcanic gas can cause people to be asphyxiated due to its density
What is a carbon dioxide?
The mountain top of this volcano was destroyed when it erupted
What is Mount St Helens?
Human exposure to volcanic hazards is increasing in these types of countries
What are least developed countries (LDCs)?
These are used to divert streams of lava
What are artificial barriers?
This type of volcano exists in the middle of tectonic plates, where a crustal weakness allows molten material to penetrate from the Earth’s interior
What is a hot spot volcano?
A volcanic mudflow composed of sand–silt sized sediments, although other volcanic material, such as pumice can be transported too
What is a lahar?
These were used to control aa lava flows during Mauna Loa's 1942 eruption
What are explosives?
This program aims to improve the detection of airborne ash worldwide and issues warning messages to air traffic controllers, dispatchers and pilots
What is the International Airways Volcanic Watch program (IAVW)?
A scale ranging from 0-8, that measures the volume of ejected products, the height of an eruption cloud, the duration of the main eruptive phase, and several other factors
What is the Volcanic Explosivity Index (VEI)?
This type of volcano occurs where tectonic plates diverge and spread
What is a rift volcano?
All the fragmented material ejected by the volcano that subsequently falls to the ground
What is tephra?
