The 1906 San Francisco earthquake occurred in California on April 18th, 1906. It mainly hit the San Francisco Bay area. Until now, the seism still ranks as one of the most significant earthquakes, not only because its sheer size, but wealth of scientific knowledge derived from it as well.
Although the magnitude of the earthquake has been redetermined through different approaches, with the magnitude range from 7.7 to 8.3, it is no doubt that the San Francisco earthquake is a catastrophe. What’s more, the total length of 1906 rupture seen at the surface is 296 miles, the offset observed at the surface was 20 feet, the shaking has lasted 45 to 60 seconds, the ground has moved at a speed of 3 miles per hour approximately. The San Francisco earthquake is truly a big one, and from these data, we could still imagine the misery scene of offset fence and the train fell

When an earthquake comes, a real tragedy is on. What makes things worse is that for a long period of time, the temblor was tagged as mysterious and unpredictable. Except for suffering from it, one can do nothing to resist it. Toady, an earthquake is still seen as a big catastrophe, but we already know more about it. We understand the forms of one quake and build the principal model of the earthquake cycle (elastic-rebound theory). We create plate tectonic theory and have some precise instrument to help us predict when the quake will occur. In the temblor that occurred in the international waters of the western Pacific on Mar 11th, 2011, the prediction of the quake won 60 seconds for the local people, and a large number of people were saved because of it. That is really amazing. It is obvious that the more we know about the earthquake, the less we suffer from it, and one efficient way to get the earthquake knowledge is to dedicate in the happened earthquake and finding the rules and theories hidden in
When one of the worst earthquakes ever hits the town of San Francisco panic ensues, but not for everyone. On April 18, 1906, at 5:15 am the city of San Francisco was demolished by a 7.8 magnitude earthquake which also led to many fires being started. There was $350m in estimated damages, and 400-750 people perished in the earthquake and fire. Around 490 city blocks were destroyed, causing 250,000 people to become homeless (A Brief Account, SF Tourism Tips). In the aftermath of the earthquake there were many eyewitness accounts written about it. The eyewitness account, “Comprehending the Calamity,” by Emma Burke and the eyewitness account,"Horrific Wreck of the City" by Fred Hewitt both describe the same event, but they both have very different
Earthquakes are a natural part of the Earth’s evolution. Scientific evidence leads many geologists to believe that all of the land on Earth was at one point in time connected. Because of plate tectonic movements or earthquakes, continental drift occurred separating the one massive piece of land in to the seven major continents today. Further evidence supports this theory, starting with the Mid-Atlantic ridge, a large mass of plate tectonics, which are increasing the size of the Atlantic Ocean while shrinking the Pacific. Some scientists believe that the major plate moveme...
Earthquakes in California are certainly not a surprise. What is a surprise is their unpredictability and randomness. Geologists say there is roughly a 50 percent chance that a magnitude 8 or more quake will hit the Los Angeles area sometime over the next 30 years. And, over the past twenty years, the Los Angeles area has witnessed several earthquakes, and in particular, two that were quite devastating; the 1971 San Fernando earthquake, and the January 17, 1994, Northridge Earthquake. Given the certainty that earthquakes will occur, they still seem to come as a surprise, and leave many communities unprepared to deal with their aftermath.
The 1906 San Francisco earthquake was one of the largest earthquakes in the United States. Even though it only lasted less than a minute, the damages and aftermath of the earthquake were disastrous. These damages were not just from the earthquake, but also from other hazards that occurred because of it. It also had a huge effect on the people living in San Francisco. Many people, the government, and other countries helped the city of San Francisco with relief goods like food and clothing. The city used up their resources in order to rebuild the city and spent a lot of money. This earthquake also started a scientific revolution about earthquakes and its effects.
The San Francisco Earthquake commenced at five thirteen o’clock in the morning, with the epicenter offshore of San Francisco. The city carried more than 400,000 people during this event (Earthquake of 1906, 1). Most of the
The 1906 San Francisco Earthquake hit the Northern California coastline. The San Andreas fault shook 296 miles of the coast causing major damage throughout San Francisco, destroying about 80% of the city. Fires broke out throughout the city that lasted for several days. This was one of the worst Earthquakes recorded in history, killing 3,000 people.("The Great 1906 San Francisco Earthquake")
Before examining the Northridge event, understanding the naturally occurring hazard that is an earthquake will help to better understand exactly what happened and why it was such an important geological event. With four distinct layers, two layers, the crust and upper portion of the mantle, compose the skin that is the surface layer of the Earth. The crust is not a single, continuous piece. It is actually several different pieces, or plates, that come together to form the puzzle that comprises the surface of the Earth. These plates are in constant motion rubbing against one another. These areas, known as fault lines, where the plates rub up against one another have spots where one plate ”gets stuck while the rest of the plate keeps moving. When the plate has moved far enough, the edges unstick and is how most of the earthquakes around the world occur” (Wald, 2012). The energy stored from the friction of the two plate...
There was a massive earthquake in San Francisco during the year of 1906. The country of United States went through great loss because of this massacre. Nearly 250,000 people had become homeless as the result of this great earthquake. Winchester pointed out the question: How unprepared was America when this disaster hit? He compared the San Francisco earthquake to the Katrina hurricane in 2005.
The San Francisco earthquake of 1906 was a one of the most devastating natural disasters that United States had ever seen at the time. Although the earthquake lasted under a measly minute, it caused significant damage and began various fires. Having started on April 16 at around five in the morning, with an approximate magnitude of 8.3, the earthquake caused an abundant amount of casualties as well as an outburst of fires that demolished countless homes and buildings. Moreover, after taking the lives of more than 3,000 people as well as the homes of 225,000 residents, many families were left homeless and permanently scarred by this disaster. Additionally, the economic impact of this earthquake, in today’s standards, caused an estimated 10.5 billion dollars worth of damage solely from the disaster and its subsequent fires.

It struck at a 9.2 on the richter scale. After the quake there was major tsunami It hurt lots of people. And it destroyed a lot of building. Scientist had no idea why this occurred so, they studied this for month. They learned so much about earthquakes.
The earthquake with magnitude 9.0 and tsunami hit many regions of Japan and destroyed everything on its ways. The effects could feel over the world. Tsunamis hit Pacific coastal lines in many countries. Numerous people died, missing, or homeless. People lived in shelter, without clean water, power, telecommunication, etc. Japan is still recovering from the damages with the help of foreign relief. Radioactive from the meltdown and the aftermath debris affects the global environment. Learning the mega-thrust earthquake will help us improves the warning system that could save people and avoid serious
The 1906 San Francisco\destroyed and devastated the city and people of San Francisco. The earthquake first shook and brought down the city, then the fires caused by the earthquake burned it down. In 1906 a 7.8 magnitude earthquake hit San Francisco that lasted less than a minute. The aftershocks left the city burning, 28,000 thousand buildings destroyed and 3,000 people dead. Also it left behind millions of dollars of damage and clean up for the city of San Francisco. After this earthquake many questioned what caused this disaster and they would soon find
In the early morning hours on January 17th, 1994 a very violent tremble took place across Los Angeles, California area that left fifty-seven people dead, more than 7,000 injured, more than 20,000 homeless and left over 40,000 buildings damaged. Around 4:30 a.m. a horrific 6.7 magnitude earthquake, that tested building codes and earthquake-resistant construction, shook Los Angeles, San Bernardino, Ventura, and Orange Counties with the most intense damage occurring in Sherman Oaks and Northridge. The earthquake caused several bridges and overpasses to collapse closing sections of the Santa Monica Freeway, Simi Valley Freeway, Golden State Freeway, and the Antelope Valley Freeway. There were also several fire outbreaks throughout the San Fernando Valley, Malibu, and Venice area because of underground gas lines that had been ruptured during the earthquake that caused additional damage.
Earthquakes belong to the class of most disastrous natural hazards. They result in unexpected and tremendous earth movements. These movements results from dissemination of an enormous amount of intense energy in form of seismic waves which are detected by use of seismograms. The impact of earthquakes leaves behind several landmarks including: destruction of property, extensive disruption of services like sewer and water lines, loss of life, and causes instability in both economic and social components of the affected nation (Webcache 2).
