For now peruse the map reading exercise. We will get email with
problems and then do them via hazard city, and email them back to
the marker that was assigned to the student. Again you will get all this
information via email shortly.
Earthquake Hazards (continuing from lecture 9)
1.Surface Faulting: structures on the fault will be disrupted by the
tearing motion. So do not build directly on active faults. ex. San
2.Ground Shaking: this is generally the greatest threat to buildings
and people. In a big earthquake, the shaking can be sever even 100’s
of kilometers away from the epicenter.
The amount of shaking also depends on the nature of the soul and
rocks in the area.
b) Liquefaction of soils
4.TSUNAMI: Japenese word for Harbour Wave. Colloquial: tidal
wave. Seismic sea wave. Generated by earthquake at sea. Veolcity can
go several 100 km in length and up to traveling speed of 500 to 800
km an hour. (commercial jet place)
o Seafloor earthquakes
o Underwater landslide
o Collapse of the flank of a volcano into the sea
o Submarine volcanic explosion
o Impact of meteorite into the ocean
5.FIRES – ex. The 1906 fire in sanfransico
6.Disruption of water supplies & disease
7. is human induced >>>>
8. Human induced seismic hazards
