Preparations for earthquakes can consist of survival measures, preparation that will improve survival in the event of an earthquake, or mitigating measures, that seek to minimise the effect of an earthquake. Common survival measures include storing food and water for an emergency, and educating individuals what to do during an earthquake. [1]
According to building codes, earthquake-resistant structures are intended to withstand the largest earthquake of a certain probability that is likely to occur at their location. This means the loss of life should be minimized by preventing collapse of the buildings for rare earthquakes while the loss of the functionality should be limited for ...
However, the remaining portions of the incident waves during a major earthquake still bear a huge devastating potential. After the seismic waves enter a superstructure, there is a number of ways to control them in order to soothe their damaging effect and improve the building's seismic performance, for instance:
Taiwan also is pushing quake drills at schools and workplaces while public media and cellphones regularly carry notices about earthquakes and safety. “These measures have significantly enhanced ...
Even if 1,000 magnitude 6 earthquakes were to occur in a region, they wouldn't happen in just the right location to prevent a larger earthquake; in fact they could increase stress along a ...
Seismic retrofitting is the modification of existing structures to make them more resistant to seismic activity, ground motion, or soil failure due to earthquakes.With better understanding of seismic demand on structures and with recent experiences with large earthquakes near urban centers, the need of seismic retrofitting is well acknowledged.
The 1755 Lisbon earthquake (Portugal) resulted in prescriptive rules for building certain kinds of buildings common in the area. [2]Following the 1908 Messina earthquake (Italy), the Royal Government of Italy established Geological Committee and Engineering Committee in early 1909 to study the disaster and recommend earthquake disaster mitigation measures.
The determination of seismic risk is the foundation for risk mitigation decision-making, a key step in risk management. Large corporations and other enterprises (e.g., local governments) analyze their 'portfolio' of properties, to determine how to best allocate limited funds for structural strengthening of buildings, or other risk reduction measures such as emergency planning.
