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).
Due to stress they shift and cause the earthquake. that zone is more subject to seismic disasters. Tectonic, volcanic, collapse and explosion, are the four different types of earthquakes. A tectonic earthquake is one that occurs when the earth 's crust breaks due to geological forces on rocks and adjoining plates that cause physical and chemical changes. A volcanic earthquake is when a volcano erupts and shakes the plates.
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.
Some of these movements will be below the ocean, which will automatically force out an enormous amount of seawater. All that water will shoot up and then come crashing down, with one side charging towards the west and the other towards the east. Within 15 minutes of the earthquake, that 700-mile liquid wall will hit the Northwest coast. It is predicted that the combination of the earthquake and the tsunami, will result in 13,000 people killed and the Pacific Northwest totally wiped out and destroyed. Not only is it terrifying that the odds of this big hit are one in ten, but also the fact that people are not even preparing for this natural disaster.
When Mount Vesuvius erupted in 79 A.D it caused a lot of destruction throughout the region in Italy. In 62 A.D, there was a fatal earthquake that damaged towns, cities, this earthquake set Mount Vesuvius in 79 AD which the volcano erupted strongly with streams of hot gases, molten rock that hit Herculaneum. The city quickly was filled up with ash, pumice, molten rock, hot gases from the volcano. When Pompeii was hit not a while after ash, pumice, molten rock fell on top of the town. Some died in their homes or shops from the buildings collapsing while others died from the poisonous fumes that were ejected out of the volcano.
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.
Day of the Disaster by Lauren Tarshis ' is mostly about a town called Pompeii and the volcano called Mount Vesuvius, when the town of Pompeii was as normal as can be "BOOM, BOOM" then it happened one of the most deadliest volcano eruption in the world. Here is what the text stated "The pumice falls with painful force. It is mixed with hot ash, which clogs your nose and throat. Many people are fleeing." I choose this one because this explains how deadly this volcano was and is and what it could do if this happened again.
History has recoded the horrific disasters worldwide. Disasters in history have always been heartbreaking and gut wrenching. No matter the magnitude of the disaster someone is afflicted negatively. Some disasters include environmental, weather and wars. Each of these phenomenon’s has left families broken, nations ruined and history wrongly changed.
The Haiti earthquake last 2010 provided a terrifying major earthquake that cause a population loss of between 100,000 and 316,000. Aside from its weaknesses preparations for such disasters, the aid sector was also unequipped for the urban challenge. Other large-scale disasters such as the Tohoku earthquake in Japan last 2011 and tsunami, and the Typhoon Haiyan in the Philippines last 2013 as well as other numerous smaller disasters triggered by natural phenomena reinforce the increasing threat of such
