You are vacationing in Tokyo, Japan when you feel the ground begin to move. At first you think you are imagining it, then it gets stronger, you can see the buildings swaying and people running. Its been 30 seconds and the eathquake is still raging. You start to notice the ground rolling beneth you and run into a clearing, far from buildings and large trees. You watch as debri falls and the ground forms small cracks and try to keep your balance. The roads begin to buckle and some buildings crumble, until finally the movement stops and silence falls. You gaze upon the damage, stunned by what just happened.

Now that the earthquake has stopped, questions start running through your head. What happend, why and how. Where did this earthquake come from? Not long after the quake, the local news station releases seismograph data from locations around Japan.

Now that you have the times for each location, use the chart provided to convert the time between the P-Wave and S-wave into distance. 

This can be done becuse the waves move through the earth at different rates, and the further away from the epicenter you are the larger the time difference between the waves.

The distances you have found are from the epicenter to the seismograph location, or the radius of the circle around each city. In order to map your data, you need the diameter of the circle around each city.

You are so close to finding out where this earthquake originated from. Now you need to map out your data to triangulate the epicetner location.  

Look for a point where all 3 circles overlap, this is your epicenter. Use the scribble tool and pick a color to mark your epicenter.
Scribble Tool:

(This is the same process we used in 2.13 Earthquake Epicenter Activity)

Draggable item		Corresponding Item
Convergent Collision		Plates moving away from each other, forming a spreading center ridge.
Transform		Subduction where one plate slides under the other, forming a trench and volcanic mountain ranges.
Convergent Subduction		Collision where the plates smash into each other and rise up into a mountain range.
Divergent		Two plates sliding against each other, either horizontaly or vertically, forming large fault lines.

Looking at this map of world wide earthquakes and volcanoes, what do you notice? What do the lines of volcanoes and Earthquakes map out?

Your data is mapped below, look for where the three cricles intersect (overlap), and mark your epicenter location.

Looking at this map of world wide earthquakes and volcanoes, what do you notice? What do the lines of volcanoes and Earthquakes map out?

In the diagram of the Earth's Interior, which part drives the movement of the plates?

What process occurs within the Earth that causes the plates to move?

What is a Seismograph?

Your data is mapped below, look for where the three cricles intersect (overlap), and mark your epicenter location.

Look at the map. What 2 plates are interacting at the location of the epicenter?

Use the Key on the map to identify the type of plate boundary the epicenter is on.

What type of movement is happening on this boundary?

Match the type of boundary with the correct plate movement.
