The AS-1 Seismograph –
Installation, Operation, Magnitudes, Calibration, Ideas for Classroom Use |
Procedure
for determining earthquake magnitude from seismograms from the AS-1
seismograph. Examples of AS-1
recordings are shown. A method of
relative calibration of the AS-1 is also provided. Information on installation, operation,
magnitude, ideas for classroom use. L.

An
online magnitude calculator for the AS-1 seismograph and AmaSeis
software. By inputting arrival
amplitude, wave period and epicenter-to-station distance in degrees, the
earthquake magnitude is calculated.
Complete documents describing the calculator can also be downloaded in
MS Word or PDF format, as well as a version that can run locally on your
computer. |

of results of earthquake monitoring with the AS-1 Seismometer and AmaSeis
Software. Examples of recorded
seismograms and earthquake catalog are described and shown. Comparisons of S-P distance determinations
and Magnitude calculations with official results are shown. |

Teaching
modules and resources for use with the AS-1 seismograph and seismograms and
the AmaSeis software. Includes S minus
P earthquake location, magnitude calculations, a tutorial for using AmaSeis,
and an activity relating to the frequency of occurrence of earthquakes. There are eight modules or resources
listed. |

an earthquake epicenter to a seismograph station. The site also includes a travel time curve
plot, travel time tables and expected amplitude information. Useful for distance calculations for AS-1
