Kilauea: Volcano is erupting in two different locations. On the Pu’ u ‘O’o crater activity has increased overnight with lava flows from the east crater howl and two spatter cones on the crater.
Describe the correlation between earthquakes and volcanoes in therms of the Theory of Plate Tectonics.
Because the plate are moving constantly, they are either subducting over another plate or pulling away from a plate, there is constant change on the earths surface. While the plates move past or under one another it may cause an earthquake to occur. This is the release of pressure along the crust which causes the plates to shake. Because of this movement of the plates there can also be magma flow beneath and through the crust. These flow causes volcanoes. There are many different types of volcanoes that occur depending on where the plates are moving and they also produce different viscosity of lava. Meaning there is either a fast lava flow which causes more regular eruptions or the active volcano but less explosive then a low viscosity lava flow.
Describe the spatial relationship that exists with these forces of nature:
There are volcanoes where earthquakes are because when there is a fault in the crust then magma is able to flow under the crust and form a volcano. Also when there is a fault there is slippage when the fault is subducted under the crust and and that causes a drop in the surface and shaking. The fault and subduction of plate cause both volcanoes and earthquakes.
Describe the spatial distribution that exists with these forces of nature:
When magma pressure builds up in a volcano and finally the volcano erupts then this release of pressure can cause an earthquake to occur. This would also be a consideration when you have an earthquake and the focus is close to an earthquake it can cause a shift in pressure of the volcano and an eruption as well.
Describe what you learned about earthquakes and volcanoes that you did not know before this course.
I knew more about earthquakes before this course because of where we live. It has been explained to me in other classes through out my education. However, I did not know that Utah was over due for a large earthquake by hundreds of years. Volcanoes were more of a mystery. I did not know how many different volcanoes there were or why one would be explosive and one might not be. I also didn’t know much about the gases they emit.
