		Seismograph records of the seismic waves produced by the collapse of the WTC towers in the 9/11 terrorist attacks, Lamont-Doherty Earth Observatory.
		This is because seismic moment is derived from the concept of moment in physics and therefore provides clues to the physical size of an earthquakeâ”the size of fault rupture and accompanying displacement and length of slippageâ”as of as well as the amount of energy released.
		The seismic zone maps usually show the severity of expected earthquake shaking for a particular level of probability, such as the levels of shaking that have a 1-in-10 chance of being exceeded in a 50-year period.

		This is typically the lowest level of retrofit applied to hospitals, fire fighting stations, public safety (police) command centers, and the like and is often the most economical level of retrofit and design for transportation infrastructure such as rail and highway roadways, bridges, and tunnels.
		Traditional seismic design assumes that the lower stories of a building are stronger than the upper stories and where this is not the case the structure will not respond to earthquakes in the expected fashion.
		The safety of underwater tubes is highly dependent upon the soil conditions through which the tunnel was constructed, the materials and reinforcements used, and the maximum predicted earthquake expected, and other factors, some of which may remain unknown under current knowledge.

		Seismic retrofitting is the modification of structures to make them more resistant to ground motion and/or soil failure due to earthquakes.
		In general, though, modern steel frame high rise buildings are not as subject to dangerous motion as are medium rise (eight to ten story) buildings, as the resonant period of a tall and massive building is longer than the approximately one second shocks applied by an earthquake.
		Traditional seismic design assumes that the lower stories of a building are stronger than the upper stories and where this is not the case the structure will not respond to earthquakes in the expected fasion.

	Household seismic safety - Wikipedia, the free encyclopedia
		Seismic and seismic event refer to earthquakes, motions of the ground that can be hazardous to the occupants of buildings and the security and utility of structures such as bridges and tunnels.
		There remains much that can be done to enhance home safety by the occupants, even if they are inexperienced mechanically, and some of these methods (such a securing water heaters) may be shown in some detail.
		Effective securing of household equipment and furnishings may require some thought - mostly along the lines of "what could happen", "how heavy is this", and "where are the strong points to secure to".

	Earthquake
		Seismic waves including some strong enough to be felt by humans can also be caused by explosions (chemical or nuclear), landslides, and collapse of old mine shafts, though these sources are not strictly earthquakes.
		Seismologists now favor a measure called the seismic moment, related to the concept of moment in physics, to measure the size of a seismic source.
		The seismic moment is calculated from seismograms but can also by obtained from geologic estimates of the size of the fault rupture and the displacement.

	Earthquake - Wikipedia, the free encyclopedia
		It is usually possible to identify a point from which the earthquake's seismic waves appear to originate.
		There are four types of seismic waves that are all generated simultaneously.
		Earthquakes such as these, that are caused by human activity, are referred to by the term induced seismicity.

	Brief 41: Seismic Retrofit
		While some seismic upgrading work is more permanent than reversible, care must be taken to preserve historic materials to the greatest extent possible and for new work to have a minimal visual impact on the historic appearance of the building.
		The two goals of the seismic retrofit in historic buildings are life safety and the protection of older and historic buildings during and after an earthquake.
		Planned seismic retrofit work may add between $10 and $100 per square foot to the cost of rehabilitation work depending on the level of intervention, the condition of the building, and whether work will be undertaken while the building is occupied.

		This rift is known as the Reelfoot Rift and coincides with the northernmost portion of the Mississippi embayment.
		The largest New Madrid seismic zone earthquakes to have occurred since then were on January 4, 1843 and October 31, 1895, with magnitude estimates of 6.0 and 6.2 respectively.

		Plumbing codes have been developed over the years to promote health and safety, and while the specifics vary from jurisdiction to jurisdiction, they all share a common element, to minimize the spread of disease.
		The basic principles involved are to ensure that the source of water remains pure, and that wastewater stays isolated and free flowing.
		It can be removed with various household cleaners and bleach, but the most effective way to prevent it is by providing adequate ventilation.

	earthquakes
		At the Earth's surface, earthquakes may manifest themselves by a shaking or displacement of the ground and sometimes tsunamis, which may lead to loss of life and destruction of property.
		When the failure at the fault plane results in a violent displacement of the Earth's crust, the elastic strain energy is released and elastic waves are radiated, thus causing an earthquake.
		Thus, the 50-megaton nuclear bomb code-named Ivan detonated by the Soviet Union in 1961 created a seismic event comparable to a magnitude 7 earthquake, producing the seismic shock so powerful that it was measurable even on its third passage around the Earth.

		The seismic moment and its associated moment magnitude scale are based on the fundamental faulting parameters of best fit planar fault area, average fault slip, and the rigidity of the surrounding medium.
		The Mercalli intensity scale, which measures the effects of the seismic waves, is a commonly referenced intensity scale.
		It is principally due to the transfer of the seismic motion from hard deep soils to soft superficial soils and to effects of seismic energy focalization owing to typical geometrical setting of the deposits.
