Earthquake preparedness. 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 ...
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.
An earthquake – also called a quake, tremor, or temblor – is the shaking of the Earth 's surface resulting from a sudden release of energy in the lithosphere that creates seismic waves. Earthquakes can range in intensity, from those so weak they cannot be felt, to those violent enough to propel objects and people into the air, damage ...
School Safety Preparedness Drill (SSPD) is an annual earthquake preparedness drill being organised in schools of North and North Eastern states of India commemorating 4 April 1905 Kangra earthquake. The two non-governmental organisations GeoHazards Society (GHS) and GeoHazards International (GHI) has been working for earthquake safety in South Asia for many years. In the year 2009 both the ...
Seismic base isolation, also known as base isolation, [3] or base isolation system, [4] is one of the most popular means of protecting a structure against earthquake forces. [5] It is a collection of structural elements which should substantially decouple a superstructure from its substructure that is in turn resting on the shaking ground, thus ...
Earthquake engineering is an interdisciplinary branch of engineering that designs and analyzes structures, such as buildings and bridges, with earthquakes in mind. Its overall goal is to make such structures more resistant to earthquakes.
The Earthquake Early Warning logo used by the Japan Meteorological Agency is a Namazu (鯰). Many earthquake-preparedness activities in Japan use the catfish as a mascot; in Japanese mythology earthquakes were caused by a giant catfish, or seeing catfish foretold an earthquake.
Seismic hazard. Surface motion map for a hypothetical earthquake on the northern portion of the Hayward Fault Zone and its presumed northern extension, the Rodgers Creek Fault Zone. A seismic hazard is the probability that an earthquake will occur in a given geographic area, within a given window of time, and with ground motion intensity ...
