The hot material deep within the surface of the Earth melts to produce magma beneath the Pacific Plate. Each of the volcanoes in the Hawaiian island chain go through a series of stages in their lifetime. In short, the shield stage, postshield stage, erosional stage, rejuvenated stage, coral atoll stage, and the guyot stage. The shield stage is divided into three phases, the submarine, explosive, and subaerial. Following the gentle explosions of the pre shield stage, the submarine phase begins with pillow lava eruptions.
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 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.
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.
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.
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.
I choose this one because this explains how deadly this volcano was and is and what it could do if this happened again. "Then more terror. As the volcano loses energy, the molten rock and ash mix together to create a super heated wave that rushes down the mountain at 80 miles an hour. This burning avalanche is known as a pyroclastic flow.
Due this activity collar pieces and basalt are mixed and can be found in the tuff and magmatic debris of the cone. Diamond Head is a part of the complex of cones, vents that are associated to eruption flows which are known as Honolulu Volcanic Series. This Volcanic Series of the volcanic eruption has created many of O’ahu’ recognized landmarks, including Diamond Head. (Diamond Head Crater, n.d.) In addition, it is believed that Diamond Head was built up by a brief single eruption that occurred 300,000 years ago. The highest peak of the crater is southwestern due to the winds that were blowing ash in this direction during the eruption.
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).
Global Environment Problems Global environment can be defined as the environment about our nature and the surroundings that influence worldwide scale an environment could be a desert or polar land. Environment problems: Our environment constantly changing. There is no denying that, However, as our environment changes, so does the need to become increasingly aware of the problems that surround it. With a massive influx of natural disasters, warming and cooling periods, different types of weather patterns and much more, people need to be aware of what types of environmental problems our planet is facing. • Pollution: Pollution of air, water and soil require millions of years to recoup.
