Encontré esto: Immediately following large seismic events in mines, there is a short-term increase in levels of seismicity, which gradually decays to background levels, typically over several hours. During this time of elevated seismic activity the risk of aftershocks with sufficiently high magnitude to cause damage is also high. Restricting access to areas of a mine for sufficient time to allow this decay of aftershock events is the main approach in re-entry strategies. to greater depth, including a number exceeding 2km. Entiendo entonces que cuando dicen "At background" estarían hablando de cuando los niveles sísmicos regresan al nivel base. ¿Estoy en lo correcto? |
