seismic source model and an updated earthquake catalogue. EARTHQUAKE MONITORING AND INFORMATION SERVICES IN HONG KONG HKO has been monitoring distant earthquakes since 1921 using longperiod seismographs. It established a shortperiod seismograph network for monitoring locally felt earth tremors in 1979. At present, HKO is operating a standalone

So, we have placed monitoring stations, called seismographs, at specific points around the world. When the vibrations of the earthquake are felt, this causes a finely balanced needle to move a pen across a scrolling chart of paper that indicates the intensity (magnitude) of the vibrations and the exact time they were detected.
A realtime HF propagationmonitoring tool developed by Schwarz and the MDSR team, ... Schwarz said that in 72% of the earthquake studies, the RF Seismograph was able to detect an increase in noise on 80 meters, typically before and after the event.

As I write this, a strong earthquake has just struck downtown Los Angeles, not the Big One, but definitely a good jolt and a possible warning of things to come. Creepy.
NEW: Personal Seismic Monitoring The Raspberry Shake Personal Seismograph is an allinone, IoT plugandgo solution for personal seismology OSOP, integrates a vertical velocity sensor, the digitizer, the hyper damper, and the computer into a single box.
SMAs, or strong motion accelerographs, are usually all that is required for monitoring the response of a structure during an earthquake, whether this a building, bridge, dam, power station, or any other critical infrastructure that could be affected by a large earthquake. Signals that are too weak to be clearly visible on an accelerograph will ...
