How can I make my own seismometer?
The TCI Seismometer. The TC1 is a vertical seismometer with a natural period of approximately 1 second. Open-source hardware - based on the Arduino Uno - boosts the longer periods in its recordings, so that teleseismic earthquakes are routinely detected, in addition to regional seismic activity. All plans for the TC1 and the interface between sensor and computer are freely available online to build your own, but the TC1 can also be purchased as a kit. Many amateurs start with a horizontal-sensitive instrument built on a "garden gate" principle. Many hundreds of variations on this basic principle have been implemented in sensors built by amateurs all over the world The "Lehman" horizontal seismometer designed by James D. Several articles for constructing this type of horizontal seismometer can be found with an Internet search on the words "Lehman" and "Seismometer" in your favorite search engine.
Desktop seismology: How a maker-inspired device is changing seismic monitoring
Created in , the Raspberry Shake is a personal seismograph that can detect local to regional earthquakes. Marketed toward makers and the earthquake-curious, it also has the potential to help professionals increase the station density of seismic monitoring networks. Credit: OSOP. There are many ways to track this shaking, ranging from sensitive, expensive seismograph stations to various citizen-science approaches, including the U.
A seismometer is an instrument that responds to ground motions, such as caused by earthquakes, volcanic eruptions, and explosions. Seismometers are usually combined with a timing device and a recording device to form a seismograph. Such data is used to locate and characterize earthquakes, and to study the Earth's internal structure. A simple seismometer, sensitive to up-down motions of the Earth, is like a weight hanging from a spring, both suspended from a frame that moves along with any motion detected.
