According to a study on the French DEMETER satellite, many large earthquakes are accompanied by ionospheric disturbance anomalies of different degrees before they occur.2023-10-30T11:54+0100mdpi-d5813fa3ce410527a1d1faaedb76ae7d20231030115400https://www.mdpi.com/2075-5309/13/11/2741Applications of the American Seismic Isolator Standard “SIS” are summarized. The SIS is the only construction standard that specifies design criteria for retaining the functionality of hospitals after earthquakes. The SIS specifies limits for in-structure accelerations and deformations.2023-10-30T11:05+0100mdpi-6b83435e33345492fabf7393c36d243a20231030110500https://www.volcanodiscovery.com/earthquakes/quake-info/7972571/mag4quake-Oct-29-2023-CATAMARCA-Argentina.htmlSeismic station: Copiapo (Tierra Amarilla), Chile (GO03/C network) | Distance from quake: 282 km / 175 mi | Show on map Station Info Seismogram (vertical component) around time of quake.
