SEISMOLOGY x EARTHQUAKE SCIENCE xx GEOLOGY Laser experiments. (1) Optical seismometer. Includes instructions for a photographic recorder which makes a permanent record of earth movements over a 24-hour period. (2) Laser listening device. Modulated laser light is picked up by a simple parabolic detector. Build an earthquake detector (vibration sensor). Can also be used as a burglar alarm, intrusion detector, or in a game of skill. Est. cost: $25 (kit). Listen to the earth with this seismic detector. A portable and paperless device that can be used with various transducers (seismometers, LVDTs, differential pressure sensors, accelerometers, ...). Seismic retrofits. Anchor bolts and shear walls are the way to beef up older homes in earthquake-prone areas. Earthquake-country timber frame. How to satisfy both the building code and traditional sensibilities when doing timber frame construction in earthquake-prone areas. Riding out the big one. A structural engineer explains what happens to a wood-frame building in an earthquake and how it can be constructed to resist collapse. House building lessons from the Los Angeles earthquake. Low-cost way to make your buildings reasonably earthquake-proof. Earthquake detector circuit is really a simple transistor switch (circuit) which incorporates a mercury-switch. Seismograph will record earth tremors up to 5,000 miles away. Est. cost: $15. Build a simple pendulum seismometer that uses a telephone pickup coil and amplifier circuit to record an earthquake on a chart recorder or oscilloscope. Seismograph equipped with antidrift device. Plans for four simple seismoscopes and a seismograph for amplifying and recording vibrations. A sensitive mercury-tiltmeter that serves as a seismometer. A simple version can detect a tilt of only .002 second of arc. How to build a seismometer, designed by Barry Shackleford and Jim Gundersen, that uses electronics to compensate for the "roll-off" of the pendulum. Can be used to drive a pen recorder. How to build a simple seismograph to record earthquake waves of magnitude 4.8 or more on the Richter scale. Monitoring earthquakes in your backyard. How to build a seismograph that can be linked to a computer or chart recorder. Includes pseudo-code outlining the procedure for capturing and plotting what a seismograph picks up during a normal 24-hour period and use it to set the acceleration threshold. Includes circuits for accelerometer and chart recorder. Detecting low-frequency electromagnetic waves from natural sources, such as those that occur before earthquakes and that are associated with storms and solar wind. Includes instructions for constructing and calibrating an antenna to interface with a computer or chart recorder. Includes schematic for circuitry to amplify the antenna signals. Getting ready for a big quake. How to check your house for earthquake safety and make it more quake-resistant. Guide to help you prepare for the next earthquake. Part 1. How to secure your house and possessions. Includes information on strengthening the house and keeping furniture and other items from falling and breaking. Guide to help you prepare for the next earthquake. Part 2. How to secure your family and your neighborhood. Emergency supply cache, what utilities to turn off, living in a disaster area, etc. | |||||||||
