Question

how close is the earthquake epicenter to any volcano found in the map​

Answer 1

Answer:

As per comparing the map of earthquake epicenters with the map of active volcanoes, it can be observed that it overlaps. The location of the volcanoes is where earthquakes mostly occurs. From the observation it can be said that earthquakes are mostly present where there is a near volcano in the area.

Answer 2

By measuring the amplitude of the strongest wave, the epicenter of the earthquake would be found.

Explanation:

• Check the scale on your map. It should look something like a piece of a ruler. All maps are different. On your map, one centimeter could be equal to 100 kilometers or something like that.

• Measure the distance between the first P wave and the first S wave.

• Measure the amplitude of the strongest wave. The amplitude is the height (on paper) of the strongest wave.
• Place a ruler (or straight edge) on the chart between the points you marked for the distance to the epicenter and the amplitude. The point where your ruler crosses the middle line on the chart marks the magnitude (strength) of the earthquake.
• Do the same thing for the distance to the epicenter that the other seismograms recorded (with the location of those seismographs at the center of their circles).
• All of the circles should overlap. The point where all of the circles overlap is the approximate epicenter of the earthquake.
