Talk:Long period ground motion

Frequency of LPGM
I've seen in the editing history a lot of changes and "debate" on the definition of wave-length of LPGM. In here this is not fixed, but rather something that depends on the application. Typically the maximum frequency will be between 1 Hz and 0.3 Hz. IDon&#39;tFindAName (talk) 18:00, 12 January 2024 (UTC)


 * If you want some sources using different values:
 * LPGM in engineering (short-waves: <1s; long-waves: up to >20s)
 * Early forecast in earthquakes (approx. 2 to 10s)
 * Analysis of LPGM in earthquake (3 to 16s)
 * Study on Quasi-Static Loading Protocols (1 to 10s)
 * JMA introduction on LPGM (1-2s to 7-8s)
