Tsunamis happen when the plates on the crust of the earth move, therefore moving the entire plate so that the water rises and is pushed forward, therefore causing a tsunami (Drohan, 2009, p.21). These tectonic plates are everywhere, under everything from the biggest mountain to the smallest hill. Though it is infrequent, volcanoes have been known to cause tsunamis. It happens when to volcano begins to erupt, but instead of coming out from the top of the volcano a lateral blast shoots out from the side. Next, a quickly moving avalanche of lava pours into the water near it causing the wave to travel to distant coastlines (Springer, 2005).
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?
Convection Currents The Alaskan Way Viaduct will collapse if an earthquake happens. Tectonic plates rubbing together causes an earthquake. What causes them to rub together? An earthquake happens through a sequence of cause and effect. Altogether, temperature, density, and convection currents work together to cause an earthquake.
The earthquake was caused by the Nazca plate releasing tension and descending 15 meters underneath the South American Plate. Many people had got the warning, and evacuated, but most of them stayed back to fight through the storm. This caused a 7.6 magnitude earthquake , but the worst was still
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.
This causes a loss of lift, and more drag, which can cause a stall to occur at higher airspeeds. After studying analysis from the fdr (flight data recorder) the NTSB concluded that the de-ice boots were turned on once the crew noticed the ice accumulating on the wings. The de-ice boots inflate to remove ice from the wings. The NTSB then concluded that the ice was not the primary factor of the crash. After further analysis the NTSB found that once the stall shaker activated and the crew noticed it, they made a fatal mistake.
Poor oxygen saturation relative to FiO2 and crepitation are secondary to pulmonary congestion and oedema. Backwards cardiac effects increase hydrostatic pressure, causing fluid filtration into the lungs, resulting in impaired alveolar gas exchange and oedema in the lung. Thus, causing reduced oxygen saturation and crepitation as alveoli pop open after being collapsed by oedema (Murray,
Impact of low temperature on muscle power The reduced skin temperature cause relative levels of body cooling, which lowers the muscle temperatures. Consequently, the muscles weaken and result in impairment of the neuro-muscular function, which cause most of the skiing injuries. In addition, the drop in temperature can result in cold injury. Cold injury occurs in the exposed body parts like the feet, hands, and face, due to formation of ice crystals, freezing of tissues, or vasoconstriction which limits blood flow to the exposed body part, which results in ischematic cold injury. Local injury to the eyes is causing blurred vision and corneal edema results due to competing in the low temperatures.
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.
