Explanation:
You can make a simple seismograph to demonstrate how this machine works.
Fill a 2-liter soda bottle with water and use wire to suspend it about 1′ above the surface of a table, using a sturdy stick or ruler set across stacks of heavy books. (The bottle should hang freely between the books.)
Tape a sheet of paper with aluminum foil underneath it to the table, beneath the bottle.
Roll a felt-tip pen in a piece of paper, and tape it loosely enough for the pen to slide up and down.
Tape this roll to the side of the bottle so that the pen’s tip touches the paper.
Shake the table back and forth, gently at first and then a little harder. (Don’t move the table’s legs; shaking is enough.)
When you’re done, examine the paper. What kind of record is there of the ‘quake’?
There’s another measurement used for earthquakes: the Modified Mercalli Scale is used to measure intensity, or how strong the effects of the quake are. The intensity varies based on position relative to the epicenter of the earthquake, so one earthquake does not have a set number from the scale assigned to it as with the Richter scale.
Hope this helps you
