Tragic Bhuj Earthquake

Surprisingly, there are also tsunamis are caused by landslides under the water and they are called a submarine landslide. Often, these occur by earthquakes as well. These happen under the water and can cause the biggest and most harmful of all of the tsunamis ( Springer,

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).

They have the same impact like secondary hazard. They are tsunamis, secondary hazard, that causes after the earthquake, tsunami had killed a lot of people and destroy area around there. The effect for Valdivia earthquake are too big so they’re traveled across to the Pacific Ocean and traveled along to the southern Chile, Hawaii, Philippine, Japan and etc, with the speed are over than 200 miles per hour. While the effect for Alaska is also big, that why this incident which is caused tsunami and massive landslides are also affect a lot in Canada to Hawaii.

Throughout the rest of the year smaller aftershock occurred periodically. Because of the earthquake, four hundred million dollars was recorded in damages. Major structures were destroyed throughout the cities in Alaska. The four and a half minutes of shaking also caused landslides and avalanches. Over one hundred and thirty thousand square kilometers received the most damage.

The developments of the plates in the world 's hull cause them. These plates don 't generally move easily and can stall out, bringing on a development of weight. It is the point at which this weight is discharged that a tremor happens. Thusly, a tremor under the water can likewise bring about a wave, as the shudder causes incredible waves by pushing vast volumes of water to the surface. Tidal waves can likewise be created by submerged volcanic ejections.

Being close to the shoreline at a subduction zone can be very dangerous if a megathrust occurs. A famous example would be the 2011 tsunami in Japan which resulted in a 9.0 magnitude earthquake. The tsunami waves rose to a height of 3 to 38 meters and hit on Honshu’s coastline causing many casualties and devastating damages to the vicinity (Sorkhabi, 2011). Knowing that the subduction zone can creates megathrust to cause tsunamis, people have adopted preventive measures to reduce death toll. Educating civilians about the warning signs before the arrival of a tsunami wave such as waves retreating rapidly from coastline and vibrations of the ground is important.

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.

Earthquakes affect many people worldwide. An earthquake occurs when the earth begins shaking and releases energy in earth’s lithosphere that creates seismic waves. CDMX gets most of its seismic activity from the Cocos and Pacific plates sliding against and under the North American Plate, making it one of the most active trenches in the world. Mexico City, which sits through the San Andreas fault, was hit by a major earthquake on September 19, 1985. Mexico City’s population was roughly 77 million before the earthquake hit.

On the first day of the eruption on the 18th Mount Vesuvius made it rain rocks which were large, this covered the towns in metres of ash, lava and debris. Citizens could hear the roaring, rumbling and shaking as lava came down the mountain. When Italy’s allied forces had arrived for war it was unfortunate they had a horrible surprise because Mount Vesuvius had had destroyed Italy’s air forces planes at Terigro Airport. Over 12,000 people were displaced from their homes because of the disaster. The eight lava fountains that were created which were all around the place, as the days went by these fountains intensified.

A storm surge is an abnormal rise in the level of the sea along a coast caused by the onshore winds of a severe cyclone. According to the article “Hurricanes”, “Storm surges are frequently the most devastating element of a hurricane.” Furthermore, a storm surge can cause a major flood. According to “Hurricanes”, “ When a hurricane makes landfall it often produces a devastating storm surge that can reach 20 feet (6 meters) high and extend nearly 100 miles (161 kilometers).” In conclusion, hurricanes can cause natural disasters, destroy many things such as buildings, cities, etc., and can form a storm surge. On the other hand, hurricanes have many causes. According to “What Causes Hurricanes?” the article stated, “Hurricanes start when warm, moist air from the ocean surface begins to rise rapidly, where it encounters cooler air that causes the warm water vapor to condense and to form storm clouds and drops of rain.” This shows that hurricanes form by warm, moist air from the ocean
