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? San Andreas fault is major fracture of the Earth’s crust in extreme western north America (Brittanica). San Andreas fault have caused so many earthquakes in U.S.A, causing many destruction, and causing lost of lifes. Now, What made Northridge Earthquake so destructive? While the Northridge earthquake was happening Californian people couldn’t predict it (u-s-history.com).
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 .
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
Informative Speech Outline Speaker’s Name: Luz Singh Speech Topic: Safety; Before, During and After an Earthquake General Purpose: To Inform Central Idea (Main Goal): Help the audience prepare for a massive earthquake. A. Introduction Attention Grabber: I would like to begin by recalling the earthquake of a magnitude of 7.1 in the Ritcher Scale, that struck the center of Mexico this past 19th of September. (Transition): What would you do if in this precise moment the floor beneath you begins to tremble, the picture frames fall suddenly and the windows chatter? B.
The surface where they slip or collide is called a “fault place”. The location below the earth’s surface where the earthquake starts is called the “hypocenter”, and the location directly above it on the surface of the earth is called the “epicenter.” Foreshocks, Mainshocks, and Aftershocks Sometimes an earthquake has fore shocks. These are smaller earthquake that occurs before a larger seismic event. The largest main earthquake is called the “main shock”. Main shocks are always
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
Tsunami Tsunami Why are tsunamis so dangerous to humans? To begin this essay, I think first of all describe what a tsunami is and then be able to manage my question: Why are tsunamis so dangerous to humans A tsunami is a huge wave that can be up to 30 meters high. Tsunamis can be formed by landslides or volcanic eruptions underwater or when a meteorite crashes into the sea. Tsunamis occur, however, usually associated with earthquakes on the seabed due to movements in the earth 's crust or upper mantle. When this is done is created a vertical offset, the seabed drops or raised along a fault and this in turn creates a movement of large masses of water forming two tsunami waves that move in different directions.
EARTHQUAKES AND SEISMIC ZONES Japan has always had a history of experiencing tectonic movements and volcanic activities. The movements that were taking place during the Paleozoic, Mesozoic, and even during the Tertiary times are still proceeding today. Earthquakes are too felt across the country at each and every part, as they accompany movements along the fault lines and volcanic activities. The conditions of seismicity in the Japanese Arc System are very intricately linked to the Plate Boundary Zones and the Active Fault Systems. The Kuril Trench delineates the loci of the Plate – Boundary earthquakes in Hokkaido.
I think the three main reasons are: Natural disasters, foreign invasions, and the city’s military problems. One of the biggest reasons to explain this disaster is the never ending natural disasters. In three-hundred-thirty-six CE, the city of Rome was shook by a deadly and devastating Earthquake. (Doc F). The Earthquake shook the Mediterranean sea along with the land, causing an additional flood.
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
