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?
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
(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
Nevado del Ruiz Case Study The Eruption and its Impacts What happened? On November 13th, 1985, the Nevado del Ruiz volcano erupted triggering destructive lahars, which caused approximately 23 000 human deaths, 4500 were injured and, following the catastrophe, 8000 became homeless . Signs of seismic activity can be traced back to July of the same year, where seismograph on the mountain showed uncharacteristically seismic activity levels . Later, in September 1985, not only had the level of seismic activity increased in the region, but steam explosions accompanied them . In November, seismic activity was observed near the summit of the volcano .
The theme of this book is about a volcanic eruption that occurred May 18th, 1980 at 8:32am at Mount St. Helens. The explosion was equal to ten million tons of dynamite and shot up into the sky for more than 12 miles. These toxic gases that shot out of the volcano covered a great deal of the forest. As a result, most of the forest was burnt down almost instantly by the massive blast.Leading up to the eruption there were many warning signs, including: large cracks in the mountain and small earthquakes. However, the eruption on May 18th was a true surprise.
The Yellowstone Caldera is a volcanic feature formed by the collapse of a volcano into it’s own magma chamber in the North Western edge of Wyoming. Calderas are cool, I’ll give you that. But do you know what’s even cooler? A supervolcano. Supervolcanoes are even more powerful than regular volcanoes.
Notes: Tropical Cyclone Tracey caused an impact in economy of about 950 million dollars in. Also, Tropical Cyclone Tracey lead to a loss in population which dropped the people in jobs decimating local businesses. Tropical Cyclone Tracey destroyed over 9000 homes. Most of the buildings were not built to cyclone regulations despite they were in the cyclone belt. This would have cost them lots of money to rebuild everything again and would have taken a long time to regrow the environment to how it was before.
In fact, a mushroom cloud reaching 13, 716 meters and a 3.2 kilometer long firestorm appeared. The effects of the blast were absolutely terrifying. Above 60, 000 of Hiroshima’s 90, 000 buildings were completely destroyed, all objects made from metal, clay and stone melted, and many faced severe health problems from exposure to high levels of radiation. In terms of deaths, approximately 70, 000 people were killed instantly from the explosion, and just as many died five years later. In summary, the city was left in little more than ashes, with two-thirds of it destroyed.
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
On May 18th, 1980, thirty-five years ago, Mt St. Helens erupted and changed the course of history. This towering Washington volcano is part of the Pacific Ring of Fire. During the eruption the mountain spewed hot gases, rocks and, ash into the sky causing a mud flow down the mountain 's sides. According to the National Oceanic and Atmospheric Administration," this was the deadliest and most economically destructive volcanic event in the history of the United States". It destroyed over 230 square miles of land.
Approximately 25 million years ago, all of Eastern Washington was flooded due to the eruption of the Columbia River Basalts. As the molten rock came to the surface, the Earth 's crust gradually sank into the space left by the rising lava. Explosions of magma filled the area and the coverage was extensive. The now Columbia River Plateau was filled with basalts and formed rivers through the areas of flow. Grande ronde and wanapum basalt was created by fissures about 17-15 million years ago and made up about 85% of the flow.
The foundation states that “by studying the pattern behavior of the cycles and its previous eruptions by examining the rock minerals in the vicinity they’re given better clues to suggest the volcano is on its calm stage”. The last major eruption from the Yellowstone Caldera dropped many inches of ashes into the lands and sulfur up into the atmosphere which caused a volcanic winter. How does all these particles in the air cause a volcanic winter one may ask. Sulfur dioxide in the air reflects sunlight & radiation back into space without this sunlight temperatures decrease and crops are devastated. The last major volcanic eruption to do such a thing was in 1815 the Tambora eruption in an island of Indonesia which decreased worldwide temperature by 4 degrees and killed over 71,000 people during the eruption.
The volcano is found in the Cascade Range and is part of the cascade volcanic arc, the particular region of volcanoes is known for its extravagant ash explosions and pyroclastic flows. The 2004-2008 eruptions of St Helens, Washington, Unites states has been recorded
Recently, on January 7th 2016, there was an earthquake caused by fracking, in Oklahoma, where earthquakes are rare. This particular quake was a 4.8 on the Richter Scale, which is the highest ever recorded. It occurred in the center of the state, was felt all over. Also, within the past week, there have been more than 20 quakes all over the state. in recent years, since 2011, earthquakes have occurred more and more often.
