A fast moving, volcanic mudslide?
What is Tahar?
Creep is sometimes called this.
What is aseismic slip?
the capacity of a rock to deform to large strains without macroscopic fracturing.
What is Ductile?
this type of rock is relatively silica poor
What is Basalt?
A volcano that has not erupted recently but looks fresh without erosion.
What is dormant?
These waves have a shearing motion on the surface.
What are Rayleigh waves?
Plastic deformation
What is a small added stress yields large corresponding strains?
People build towns and farms around volcanoes for this reason.
What is fertile soil?
Sulfuric acid is erupted from volcanoes then react with water vape to create this.
What is Acid Rain?
Where do major earthquakes most likely occur?
What is On faults?
a characteristic of most rocks near or at the surface with low temperatures and pressure.
What is brittle?
This is the direction the pacific plate is moving.
What is northwest?
The largest recent volcanoes eruptions cooled the global temperature for this period of time.
What is a few years only?
Earthquakes can trigger what in the oceans?
What are Tsunamis?
rupture
What is when a rock breaks down because of sufficient stress?
Subduction zones occur at this boundary.
What is a convergent boundary?
This is something in magma that affects the type of explosion and shape of volcanoes.
What is silica content?
About 80% of all earthquakes occur here
What is "Ring of Fire"?
Elastic Limit
What is it is reached when the same increase in stress yields larger deformation than the previous same increase in stress. ?
What is shear stress?
