This earthquake caused 60 deaths, 9,000 people injured. Causing the San Fernando Valley a total pile of destruction (TheAtlantic.com). What was actually the main cause of the Northridge earthquake? Why did the Northridge earthquake caused so many destruction? The earthquake happened because of the movement from the San Andreas Fault (u-s-history.com) .This little movement from the tectonic caused big things such as earthquake, but what exactly is San Andreas Fault?
5:12 a.m., Wednesday, April 18, 1906, one of the most devastating earthquakes in the history of the United States hit the heavily populated city of San Francisco, California. This violent earthquake caused extensive and expensive damage and deaths across the city and even resulted in a fire that raged throughout the city for four full days after the earthquake. While the exact casualty tall is uncertain modern scientist estimate the death toll to be around 3,000 people with rough 25,000 left without a home(_____________3________________). However, all was not lost, from the rubble and ashes of San Francisco scientists, seismologist, and geologists alike were able to make improvements upon earthquake technology and better define what causes
Samoan 2009 tsunami report: What caused the earthquake and tsunami? On Tuesday the 29th of September 2009, a huge tsunami hit Samoa – as well as several other islands – and impacted many, leaving a path of destruction . Tsunamis are big waves that are generated from earthquakes, or volcanic eruptions that occur in the ocean . The tsunami – in the case of Samoa – was caused by an underwater earthquake . An earthquake is when the Earth’s surface shakes in response to the sudden release of energy in its lithosphere which then creates seismic waves .
Earthquakes are caused when rock underground suddenly breaks along a fault. This sudden release of energy causes the seismic waves that make the ground shake. When two plates are rubbing against each other, they stick a little. Most earthquakes occur along the edge of the oceanic and continental plates. Due to stress they shift and cause the earthquake.
The sections will slip, relieving the pressure and creating an earthquake as the energy that was held in the two sections is transferred into seismic waves, also known as an earthquake (Alvarez, et al., 2014). Conclusion The largest earthquake ever recorded on the rector scale is the Great Chilean Earthquake. At some time in the past as some point there could have been a larger earthquake, however the technology did not exist, it would not have been recorded. With the Great Chilean Earthquake there devastating effects of landscape, loss of building and home and the disastrous amount of people that lost their life. Had the technology been available in the 1960’s, the death toll would have been significant reduced and potentially they could have predicted this disastrous
How and Why Do Earthquakes Happen? World Geography Janet de Guzman Puriyod Laohabutr Grade 9G March 13, 2018 HOW AND WHY DO EARTHQUAKES HAPPEN? Abstract Introduction What are Earthquakes? An Earthquakes takes place when two blocks or pieces of the Earth’s crust suddenly slip pass one another or, the piece of land collided into each other. The surface where they slip or collide is called a “fault place”.
(National Geographic News, 2015). The tsunami resulted in at least 227,000 fatalities, destroyed 141,000 houses and took away the livelihood of more than 600,000 people. (The Bolton Council of Mosques, 2015). The force of the earthquake was thought to have had the energy of 23,000 Hiroshima-type atomic bombs. The cause of the earthquake and
Coral reefs and sandbanks, however, had not been able to prevent the tsunami were completely, but only slow tsunamis at least it can mitigate the damage. Perhaps large structures or artificial reefs an option to counter the effects of the tsunami, but as we saw in Japan did not help them anyway when the tsunami 's force was larger than the structures could withstand. Overall, one should always be prepared for a tsunami and therefore build housing and other infrastructure that is more adapted to withstand tsunamis. One can not simply answer the question as it is both an issue of such resources, space and
Introduction: Living in Skopje, the capital city of a country that is subjected to many earthquakes, some stronger than others, made me interested in earthquakes and finding more about them. The strongest earthquake Skopje has experienced throughout history that caused a severe destruction was the earthquake in 1963 measured at 6.9 on the Richter scale and 6.1 on the Magnitude Moment Scale, which killed over 1,000 people and destroyed 80% of the city. This made me curious to look deeper into the difference between the two magnitude scales, which were brought into use a few decades apart. This exploration will be comparing the two magnitude scales, The Richter Scale and the Moment Magnitude Scale, and I will look at the math used behind
