Describe the correlation is between earthquakes and volcanoes in terms of the
Theory of Plate Tectonics.
The correlation is pretty straight forward if you ask me. When tectonic plates collide the
push upwards creating land that is above sea level. This colliding creates earthquakes,
and the magma beneath the surface can be pushed up through the newly created volcano.
Analyze the spatial relationship and distribution that exists with these forces of
nature.
The spatial relationship that exists with volcanoes and earthquakes is simply that because
of the plate tectonic boundaries they occur in a lot of the same places or in the same
general area. The tectonic plates push against each other, or dive down below the other
one which creates earthquakes and the same process creates volcanoes in similar areas.
Where there is a volcano there has been, and usually are earthquakes. Where there are
plate tectonics there are these forces of nature.
Describe what you learned about earthquakes and volcanoes that you did not know
before this course.
Before this course started I didn’t know much about earthquakes and volcanoes. Like for
instance all the different types of volcanoes there can be, and what time of plate
boundaries create the different kinds. That there are all different types of fault lines and
plate boundaries that create earthquakes. Also that the pressure on the fault lines builds
up and builds up until the pressure is to great and it slips creating an earthquake on
certain fault lines. The scale of earthquake strength is also something that I didn’t
completely understand; now I do.
Earthquake #1: Oceanic-Oceanic
Magnitude: 5.6
Location: South Indian Ocean
Date: November 30, 2010
Time: 2:19 AM
Depth: 15.3 Km
Boundary: Convergent
Why this T-Plate? One plate is diving underneath the other one.
Earthquake #2: Oceanic-Continental
Magnitude: 5.1
Location: off the east coast of Honshu, Japan
Date: November 30, 2010
Time: 12:02 AM
Depth: 42.40 Km
Boundary: Convergent
Why this T-Plate? Pacific Plate is the “Ring of Fire” and is constantly having
Earthquakes.
Earthquake #3: Divergent
Magnitude: 4.8
Location: eastern Mediterranean Sea
Date: December 6, 2010
Time: 1:20 AM
Depth: 51.20 Km
Boundary: Divergent
Why this T-Plate? Because the plates are pulling apart this creates Earthquakes.
Earthquake #4: Continental-Continental
Magnitude: 4.6
Location: 12.271N, 44.036E
Date: December 5, 2010
Time: 4:07 AM
Depth: 9.5 Km
Boundary: Divergent
Why this T-Plate? Because the plates are pulling away from each other, it creates
Earthquakes.
Earthquake #5: Transform
Magnitude: 5.5
Location: Eastern Xizang
Date: November 30, 2010
Time: 4:39 PM
Depth: 17.5 Km
Boundary: Continental Transform
Why this T-Plate? Because the fault is pulling against the other side creating
Earthquakes.
