The Northridge earthquake occurred on January 17, 1994 at 4:30am,the quake was caused by the sudden rupture of a previously undocumented blind thrust fault, it hit a magnitude of 6.7, the earthquake was so strong parts of Los Angeles area, Ventura area, Las Vegas, and San Diego felt the shake of the earthquake, there were many fatalities about 60 deaths, and 2000 injuries. This earthquake caused widespread damage that included damages to freeways, apartment buildings collapsing, gas stations caught on fire, and thousands of homes were severely damaged. It was so awful it took billions of dollars to repair damages and to rebuild. The San Francisco occurred on April, 18, 1906 at 5:12 am. This earthquake magnitude was at 7.8.
The flow on effect of this was on the Biosphere this was the coastal destruction along with the Deaths and injuries of thousands. The Atmosphere then follows as it was polluted from all of the debris and the nuclear disaster caused by the tsunami and earthquake. In conclusion Japan had severe amounts of destruction and is slowly on its way to recovering as are the lithosphere, hydrosphere, biosphere and atmosphere. This catastrophic event shows the flow on effects throughout the spheres and the amount of damage one single event can have on the Earth.
Landslides, nuclear explosions, volcanic eruptions, and extra terrestrial impacts also have great water displacement results. What makes California such a potential area for this disaster is the seismic activity near its coastline. Since the early eighteen hundreds, fourteen Tsunamis have struck the California coastline. However, only six of these struck with a devastating force. The shallow beaches can add to the destructive force of the wave.
The death toll climbs to over 10,000 and is still rising (Branigan 2). The disaster in Japan began without warning on Friday March 11, 2011 at 2:46pm with a 9.0 magnitude earthquake, the strongest ever recorded in the country (Fackler 3). A massive thirty-three foot high tsunami, generated by the earthquake, swept over lands in northern Japan, taking objects and debris with it. To make matters worse, the tsunami caused the cooling systems at several nuclear power plants to fail. The disaster in Japan was a tragic event, and it had a plethora of causes and effects.
While the early warning saved thousands of people, the Japan’s Meteorological Agency underestimated this earthquake as the subduction zone of Japan should not produce the magnitude 9.0 quake (Oskin, 2013a). The Tohoku Earthquake and its tsunami approximately killed 16 thousand people, injured 6 thousand people and around 3 thousand people were missing. Most people died from drowning. Around 300 thousand buildings, 4000 roads, 78 bridges, and many more were affected by the earthquake, tsunami, and fires from leaking oils and gas. Electricity, telecommunication, and railways were severely damaged.
California is known for earthquakes that often occur at great magnitudes. Earthquakes have changed not only the environment but have also resulted in the loss of many lives. For example, the 1989 Loma Prieta earthquake with a magnitude of 6.9 was known for destroying most of San Francisco and its buildings. This earthquake caused the death of sixty people, injured around four thousand, and property damage costing up to around six million dollars. Many recognize this to be a comparable earthquake to the one that occurred in 1906 which was also a very large and devastating earthquake that occurred along the San Andreas fault line.
One of the most memorable and devastating of San Francisco’s earthquakes happened on April 18, 1906 along the San Andreas Fault. Destroying almost the entire city and putting thousands of people on the streets. The earthquake was able to do a huge amount of damage because of how poorly prepared the city was for an earthquake this
Earth has many natural disasters that affect billions of people every year. Whether it is hurricanes, torrential rain, snow storms, or even tornadoes. But there is a natural disaster which unlike the others, is unpredictable. Earthquakes, one of the most feared natural disasters can kill thousands and affect millions when they occur. They can also be a precursor to an even worse event, the tsunami.
The first historical disaster that I should mention occurred on February 9, 1971. The 6.5 magnitude Sylmar Quake caused severe damage to the Veterans Hospital, the Olive View Medical Center, and the Newhall Pass interchange freeway. Because the city wasn’t earthquake prepared, the quake caused over half a billion dollars in damage and claimed at least 64 innocent lives (Rynew, 2015). The second, and final, historical and recent disaster to mention happened in on January 17, 1994. The 6.7 magnitude Northridge Earthquake shook Los Angeles causing homes, corporate buildings, and freeways to be destroyed.
Earthquakes are one of the most damaging natural disasters known to man. They have been known to destroy entire cities in their total time of 2 to 3 minutes. Most people do not know that earthquakes are common through out the entire world; they are just more powerful in places such as California and small countries in South America. The definition of earthquake is “ a series of vibrations induced in the earth's crust by the abrupt rupture and rebound of rocks in which elastic strain has been slowly accumulating” according to Infoseek.com.. As a consequence of continental plate movement, the Earth's surface near active faults deforms before, during and after earthquakes. Similarly, the ground surface near active volcanoes also deforms as a consequence of eruptions and volcano evolution.
