Earthquake Effects The effects of any earthquake depend on a number of videly varying factors. These factors are all of:
If you like this content, help us spread awareness If you like this content, like us on Facebook: Its side-effects can be: Ground shaking Shaking of the ground caused by the passage of seismic wavesespecially surface waves near the epicentre of the earthquake are responsible for the most damage during an earthquake.
The intensity of ground shaking depends on: This depends on the type of material underlying the area. There are however some exceptions. The Earthquake in Mexico city magnitude 8.
Damage to city was extensive as Mexico city is built on a former lake made up of soft unconsolidated sediment see: Faulting and Ground Rupture When an earthquake event occurs, ground rupture is only where the fault zone moves. Those constructions built adjacent to the fault will survive while structures built across these zones will collapse.
Landslides and ground subsidence Avalanches, landslides, slumps and rock slides are triggered by ground shaking. These landslides are often more destructive than the earthquakes. A residential area in Alaska Turnagain Heights was destroyed by a shock induced landslide as well as are in downtown Anchorage.
Damage to man-made structures Damage to man-made structures, such as roads, bridges, dams and buildings from ground motion depends on the type of construction: San Fernando earthquake This aerial photograph of the San Fernando earthquake in Feb shows the extensive damage to the freeway bridge as the Earth's crust shook.
This quote is from Seismologists who believe that human construction and buildings crashing down during earthquakes are the cause of most deaths. Seismic shaking and related dangers This photo shows the extreme danger presented by seismic shaking to people in the open around buildings and on the street.
Complete facades of buildings, electric signage and windows crash and collapse onto the street below. It is known to be far safer to shelter under robust furniture than to run out onto the street. Fires Fires, often associated with broken electrical and gas lines, is one of the common side effects of earthquakes.
Gas is set free as gas lines are broken and a spark will start bringing "inferno".
To complicate things water lines are broken and so there is no water to extinguish the fire. Fires started by broken gas lines Spill of hazardous chemicals Kocaeli chemicals spill Turkey, Radioactive water leaks from Fukushima nuclear power plant Japan, Image: Liquefaction in action In the image above, some buildings toppled when the soil underwent liquefaction.
Buildings can even sink into the ground if soil liquefaction occurs. Flooding Flooding can come from many sources such as broken water main pipes, dams that fail due to the earthquake and earthquake-generated tsunamis. When an earthquake breaks a dam or levee along a river, the water from the river or the reservoir floods the area, damaging buildings and maybe sweeping away or drowning people.
Small tsunamis, called seiches occur on lakes shaken by earthquakes and are usually just a few feet high. These small tsunamis are capable of destroying houses and uprooting trees.
Also, earthquakes can alter the course of a river and can even cause it to flow in the opposite direction for a short time this happened to the Mississippi River in the late 's.
Seiche A seiche is the effect of the sloshing of water back and forth. The earthquake from Alaska on March 28th, caused seismic waves that were so powerful that bodies of water oscillated in many places across North America.
Hundreds of surface water gauging stations recorded seiches although rarely recorded before this earthquake.Direct Effects There are two classes of earthquake effects: direct, and iridis-photo-restoration.com effects are solely those related to the deformation of the ground near the earthquake fault itself.
Mar 14, · The March 11, magnitude earthquake in Japan may have shortened the length of each Earth day and shifted its axis.

NASA - Japan Quake May Have Shortened Earth Days, Moved Axis There's a problem with your browser or settings. The social impacts of the Tohoku earthquake were overwhelming.
The death toll reached approximately 19,, although a large majority of these fatalities occurred due to drowning in the tsunami. Those who did survive the immediate effects of the earthquake had to face another challenge: staying alive.
The effect of earthquake on buildings in Japan Abstract The country of Japan is an island. The population in Japan is considered quite high, about ,, people in this small country.
Therefore, this has made Japan became one of the most tightly populated country in the world, ranking the 36th placing. Earthquakes are very common in Japan. The global tourism industry has closely monitored the lasting effects of the earthquake, tsunami, and nuclear reactor issues.
Immediately after the quake, the U.S. State Department issued an advisory for Americans not to travel to Japan unless absolutely necessary.
On March 11, , a magnitude-9 earthquake shook northeastern Japan, unleashing a savage tsunami. The effects of the great earthquake were felt around the world, from Norway's fjords to.
