sizmogramë

Sizmogramë is a term derived from the Albanian language, specifically combining "sizmo" meaning seismic and "gramë" meaning record or writing. Therefore, a sizmogramë is essentially a seismic record. It is a visual representation of ground motion recorded by a seismograph. These records show the arrival of seismic waves, which can be generated by earthquakes, volcanic eruptions, or even artificial sources like explosions.

A typical sizmogramë displays time on the horizontal axis and the amplitude of ground motion on the vertical axis. Different types of seismic waves, such as P-waves (primary waves) and S-waves (secondary waves), arrive at different times and have distinct characteristics, which can be observed on the sizmogramë. The arrival times and amplitudes of these waves provide crucial information for seismologists to determine the location, magnitude, and depth of an earthquake. Analyzing sizmogramë data is a fundamental practice in seismology for understanding the Earth's interior structure and monitoring seismic activity. Historically, sizmogramë were recorded on paper scrolls, but modern seismographs produce digital data, which is then processed and visualized using specialized software.
