Build Your Own Seismometer

It's not as smart as you are, and it may occasionally give humorous, ridiculous, or even annoying results! If you used a roll of paper and a that slowly pulled the paper across the table, you would be able to record tremors over time. To correct for declination you must rotate your compass counterclockwise to correct on the East Coast and clockwise on the West Coast where the declination correction is positive. Seismic Waves: How Earthquakes Move the Earth Students learn about the types of seismic waves produced by earthquakes and how they move the Earth. Note that like the professional instrument it nicely differentiates between Primary and Secondary body waves as well as the larger surface L waves allowing distance to an event and even magnitude to be accurately measured. . Scientists who weren't in Chile during this morning's aftershocks nevertheless knew the moment the rumbling started, thanks to a global network of quake-detecting instruments called seismographs. In 1935 Charles Richter developed a system to measure the magnitude —or amount of energy released—of an earthquake.

This thread engages the upright, U, and drives the drum slowly forward as it. This can be tricky, but if you take your time and go slow there shouldn't be a problem. Grades 6 - 8 Do you agree with this alignment? It depends on how much you want to build and how much you want to buy. Experiland e-books contain detailed steps, including illustrations, to complete the science projects from start to finish. Large trucks or trains can also cause buildings to shake and can cause false readings on a seismograph if it is not isolated in some way.

I assume that you have a computer and monitor and printer that can be used for data collection and analysis. This link com-municates any motion of the drum to the short arm of the lever I. This screw will rest against the wood stand, making the wood beam hang level. The district of Messinia, where our school is located, has a history of major earthquakes. You might try buying a miniature battery-operated motor that can turn the wood dowel of the can. Ker Than, Contributing Writer on. Earthquakes by Claire and Nisha.

This is reflected in the amplitude of the signals. AmaSeis works well with Windows 10. Sparta is likely to be another victim within the next 100 years Image courtesy of Panteleimon Bazanos; data source: the automated alert system of the Institute of Geodynamics at the National Observatory of Athens Click on image to enlarge Image courtesy of Nicola Graf To encourage my students to learn about earthquakes, I acquired and set up a commercial, educational seismograph in our school figures 3 and 4 , the General Lyceum of Filiatra. In a real seismograph, levers or electronics are used to magnify the signal so that very small tremors are detectable. To strengthen the links between such schools in Europe, teachers are invited to apply for the second. We used wood, iron and marble as the materials, but any hard solid can be used.

Earthquake Location Maps

I am offering seismic systems based on my designs, and will offer kits if there is demand. Adjust the arm to horizontal using the bubble level by adjusting where the upper spring hooks onto the fixed hook see image in step 3. Have each group tell the class which seismogram they thought was which, and have the group that made the seismogram reveal the correct answer. Where the rocks broke is known as the earthquake's focus, and right above this point, up on the ground, is called the earthquake's epicenter. You can probably think of other ideas on your own. Different types of seismic waves travel at different speeds and through different parts of the Earth during a.

Then raise the stick or dowel suddenly so the card lifts off the arm without disturbing the box. They should record the code in their science notebooks or on a separate piece of paper. What forms depends on how exactly the tectonic plates are moving against each other at the plate boundary. Gather the materials you need and build the seismograph you designed. Be patient, it may take several days to a week or more for you to record your first earthquake. Today seismographs are used to determine the force of an earthquake. Project 1: Your Own Design a Think of a creative but effective way to measure the seismic waves shock waves from an earthquake.

This setup is fine since the amp is going to be in an undisturbed location near the seismometer. The designs have been replicated and installed by a small group of interested builders, and have proven quite successful in delivering a broadband seismometer performance on par with commercial instruments costing much more. You may try substituting a soft lead pencil, a charcoal pencil, a crayon, etc. After securing the spool with the bolt and nut, insert the end of the bolt into a drill press chuck and wind the wire from the purchased spool to the seismometer spool on the slowest speed. A horizontal beam like your arm holds the pen.

Three methods have been suggested: hydraulic vane in an oil bath , eddy current magnet moving across an aluminum or copper plate , and electromagnetic a damping resistor across your pickup coil. Safety Issues Tell students to be gentle with the seismogram, it is only made of a cardboard box and rulers; it can easily break or fall apart. There is a new free version of AmaSeis called that works with Windows, Apple computers and Linux computers. If you live in a city, you may have noticed that buildings sometimes shake when a big truck or a subway train rolls by. Last updated on September 09, 2016.
