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?
(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
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 .
It was the most powerful quake ever recorded. Earthquakes will occur on most plate boundaries, other than constructive as this is where new land is formed by magma moving into the gap on the plate boundaries (Alvarez, et al., 2014). Mostly happen on subductive and conservative plate boundaries examples of which are East Asia, when these boundaries crush against each other and create pressure. Eventually, the pressure will build up to a point where it overcomes the friction holding two sections of rock together. 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).
The large amount of water flooding the country can destroy buildings, roads and infrastructure, and in the evacuation drop people off each other, gridlock occurs, power supply and telecommunications goes down and entire communities may be left marginalized in 1908 hit a tsunami Messina in southern Italy that killed 80,000 people . In 1998 hit Papua New Guinea by a tsunami that destroyed towns and killed about 2200 people and 26 December 2004 happens one of our greatest natural disaster when a large earthquake on the seabed in the Indian Ocean caused a massive tsunami that among other things affected the coasts Sri Lanka, India, Thailand and Indonesia. The destruction was catastrophic and at least 230,000 people lost their lives in the disaster, including 543 Swedish
The eruption of Mt. Vesuvius and the subsequent burial of Pompeii is one of the greatest disasters known to man. The volcano erupted in 79 BC after a major earthquake in 62 BC woke up the mountain. The towns of Pompeii, Herculaneum, Boscoreale, and Oplontis were buried early morning on August 25, 79. Oplontis and Boscoreale were the first towns to be destroyed; they were buried in the first weak lava flows and explosions.
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
According to National Geographic, these waves can reach heights up to 35 meters, and are mostly the aftereffects of earthquakes. “Most tsunamis, about 80 percent, happen within the Pacific Ocean’s “Ring of Fire,” a geologically active area where tectonic shifts make volcanoes and earthquakes common.” said one of the scientists working with National Geographic(7). Above the mantle of the earth, there is a layer made of tectonic plates, which fall into either the continental or oceanic category. They move and occasionally meet, which creates stress between the rocks. Due to this stress, the plates bend and break in order to release the elastic energy stored inside them.
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
Natural disasters are a nature’s events and are uncontrollable, although predictable. They include typhoons , rainy season flooding, tornadoes and tsunami. An article in the Guardian states that a study has revealed natural disaster has displaces three times as many people as war in 2013. An average of 27 million people a year or 42 million in total in 2010 have lost their homes ( Guardian.com,2014). A tsunami event that occurred in 2004 , called the Boxing Day Tsunami, displaced 1.7 million and injured half a million of souls.
Although the city faces regular avalanches and the possibility of landslides the town’s major hazard is earthquakes. Earthquakes are the biggest threat to Juneau. The city has a history of very violent earthquakes. The earthquakes in Juneau are caused by crustal stress accumulated by the North American and Pacific plates. The city also experiences activity from the Queen Charlotte-Fairweather fault system.
Loud booms rang out. The quivering began to intensify, causing belongings to fall in residents’ homes. It was the beginning of the 5.7-magnitude Oklahoma earthquake, which struck on November 6, 2011 and resulted in significant structural damage (“Oklahoma’s Largest Quake in Decades Buckles Highway; Rattles Residents,” CNN). A journalistic study—published in the journal Geology—conducted in 2013 showed that the 2011 earthquake was actually caused by fracking, a practice in which water is injected into the Earth’s ground (“Wastewater Injection
