Difference Between Earthquake and Volcano

Volcanoes form at Earth's surface whereas earthquakes originate from deeper within the crust. ... Volcanoes are formed by release of gas and magma. Earthquakes are caused by movement along a fault. Volcanoes lead to the formation of new rock whereas earthquakes simply cause waves which disturb the rock.

Which is worse volcano or earthquake?

With the class, review that earthquakes and volcanoes are dangerous. Explain that every year, they cause damage not only to humans, but to the environment and wildlife as well. Earthquakes cause damage to structures that cannot withstand shaking. Volcanoes can cause dangerous explosions as well as gentle lava flows.

Can volcanoes cause earthquakes?

Volcanically-caused long period earthquakes are produced by vibrations generated by the movement of magma or other fluids within the volcano. Pressure within the system increases and the surrounding rock fails, creating small earthquakes.

How is the pattern of earthquakes different than the pattern of volcanoes?

At diverging plate boundaries, earthquakes occurs as the plates pull away from each other. Volcanoes form between the plates, as magma rises upward from the underlying mantle. ... First, only earthquakes occur when two plates collide (obduct), building a mountain range.

What is difference between volcano and mountain?

A volcano is a type of mountain but it has magma, crater and lava. A mountain does not have these three things. Mountains are peaceful areas whereas volcanoes are very much dangerous and not a good place to stay. ... Volcanoes can be a part of mountain ranges.

What is the most dangerous type of earthquake?

Love waves are the most dangerous of all kinds of seismic waves. They are faster than Rayleigh waves and even larger in amplitude.

Can earthquakes destroy houses?

Landslides are caused by earthquakes both by direct rupture and by sustained shaking of unstable slopes. They can easily destroy buildings in their path, or block roads and railroad lines, or take hilltop homes with them as they tumble.

Can a volcano cause a tsunami?

Although relatively infrequent, violent volcanic eruptions represent also impulsive disturbances, which can displace a great volume of water and generate extremely destructive tsunami waves in the immediate source area.

What triggers a volcano to erupt?

Volcanoes are formed by eruptions of lava and ash when magma rises through cracks or weak-spots in the Earth's crust. A build up of pressure in the earth is released, by things such as a plate movement which forces molten rock to exploded into the air causing a volcanic eruption.

How do you know a volcano will erupt?

An increase in the frequency and intensity of felt earthquakes. Noticeable steaming or fumarolic activity and new or enlarged areas of hot ground. Subtle swelling of the ground surface. Small changes in heat flow.

What is the similarities of volcano and earthquake?

This is where most volcanoes are too. However, most earthquakes are caused by the interaction of the plates not the movement of magma . Most earthquakes directly beneath a volcano are caused by the movement of magma. The magma exerts pressure on the rocks until it cracks the rock.

Is there a pattern to earthquakes?

Earthquakes can strike any location at any time, but history shows they occur in the same general patterns year after year, principally in three large zones of the earth: ... Earthquakes in these subduction zones are caused by slip between plates and rupture within plates.

Why do patterns of earthquakes exist?

The movement of the plates is caused by the convection currents in the molten magma. These puzzle pieces are called tectonic plates, and the edges of the plates are called the plate boundaries. These plates are always moving. That is why most of the earthquakes and volcanoes are found near or on the plate boundaries.
