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 ...
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.
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.
Mitigation of seismic motion is an important factor in earthquake engineering and construction in earthquake-prone areas. The destabilizing action of an earthquake on constructions may be direct (seismic motion of the ground) or indirect (earthquake-induced landslides , liquefaction of the foundation soils and waves of tsunami ).
Preventive or mitigation measures vary for different types of disasters. In earthquake prone areas, these preventive measures might include structural changes such as the installation of an earthquake valve to instantly shut off the natural gas supply, seismic retrofits of property, and the securing of items inside a building.
Every year tens of millions of people take part in a massive earthquake drill called the Great ShakeOut, which teaches people what to do and how to respond in case of a ground-rattling temblor.

Disaster risk reduction (DRR) is defined by United Nations Office for Disaster Risk Reduction (UNDRR) as those actions which aim to "prevent new and reducing existing disaster risk and managing residual risk, all of which contribute to strengthening resilience and therefore to the achievement of sustainable development".
