For instance the distance of the focus F from the station A is proportional to the P-S time at the station A. The intensity of an earthquake is gauged by its effect on the humans, the damage caused to buildings and other structures and the consequent geologic effects produced. As shown in fig. Few, if any masonry structures remain standing; bridges destroyed.
The intensity of earthquake varies not only from place to place but also at the same place. The floor is shaking harder now, and I try to stand. From the stand point of movement and tectonic events and creation and destruction of geomaterials the plate boundaries are divided into: July 17,a moderate intensity 7.
Usually the first warning of an approaching tsunami is a rapid withdrawal of water from the beach as in an exceptionally low tide to a distance of 2 or 3 kilometres.

However, the process is slow, "Remedial strengthening of buildings in the City of Los Angeles is progressing, but such efforts are slow or absent elsewhere in the region" Kerr, p.
The vibrations induced by the earthquake waves cause the open packed granular material to compact state and in the process, water may be expelled, leading to possible subsidence of the surface.
The damage caused by the Bihar earthquake of 15 January,measuring 8. These waves are created as rocks rupture under stress or friction below the surface of the earth resulting in the release of energy.
Timing of the record is done very accurately and hence relatively high drum speeds are used. Other factors, which may be responsible for the earthquakes, have been so far neglected.
As in the Whittier quake, many older buildings of types known to be vulnerable suffered major structural failures. We know the primary cause of all damages during an earthquake is ground motion.
There are also fault planes were you could have plates sliding against each other, and midplate earthquakes. Earthquakes occur in various strength. Here one part of California moves north-eastward while the other part moves south-westward along the fault plane and thus is formed transform fault which causes earthquakes.
Primary data collection methods will include observation, field measurements, strategic sampling, and seismic graphs interpretation to determine tectonic movement changes as well as climatic and ice sheet quantity variations during the period of study.
They are of the opinion that gradual increase in the seismic events in Bhatsa Dam area since is because of active faulting beneath the basaltic crust. To try and reduce these loses of friends and relatives, there are steps to reduce hazards in the home. That may seem like a lot, but when compared to the earthquake in Northridge, California in it was pennies.
California is the most risk The earthquakes pattern in the United States as per my view from the National Seismic Hazard maps of is uneven. Most earthquakes are shallow, less than 60 km, but a few are as deep as km. Alex Padilla D-Van Nuys.
