Earthquakes and Volcanoes
By: Zephyr and William
The threat of Natural Disasters is more prominent now than ever. Compared to fifty to one hundred years ago, the severity of such events; Tornados , Tsunamis, Earthquakes, Volcanoes, and Floods are hundreds of times more deadly. Natural Disasters; as defined as “Any event or force of nature that has a catastrophic consequences, such as avalanches, earthquake, flood, forest fire, hurricane, lighting, tornado, tsunami, and volcanic eruption. ” (Dictionary.com, 2014) can have devastating outcomes to anyone and anything in its proximity.
Earthquakes happen nearly everyday in Canada alone, in the last year there has been a total of 380 earthquakes in Canada. “The majority of earthquakes in Canada happen in B.C.”(earthquaketrack.com, 2016) The biggest earthquake recorded by seismometers Canada has had was the 1949 Queen Charlotte Island earthquake, which hit on August 21 at 8:01pm (PDT). Second only too the 1700 Cascadia earthquake, which reached 9.0 on the Richter magnitude scale. The Queen Charlotte Islands quake was a massive 8.1 magnitude and a maximum Mercalli Intensity of VIII(Severe). The quake expanded to more than 500km and was felt through British Colombia, Alberta, Yukon, and parts of the United States and Alaska. Notably regardless of the devastating quake no deaths were reported. Although there were no causalities, the earthquake caused extensive damage, destroyed windows, and landslides were notable. (Wikipedia, 2016)
Volcanoes, the cause by the force of tectonic plates pushing one another. Pushing lava to the surface at high speeds when erupting . Volcanoes grow year after year, when they release they can rip islands apart under them. When eruption smoke and dust fill the air, the force of these eruptions many items over the that of a nuclear bomb. The damage of such a thing is one of the most devastating disasters that nature can bring. Some such disasters are the splitting of land mass they sit on. Rivers of lava flowing and lava bombs falling upon the surrounding area. Even something that has been called a small ice age can happen a by-product of a volcano going off. The only way of preventing or surviving something like this for sure is knowing it’s coming and leaving the area. Far, very far from the area of the volcano.
Another effect of a volcano eruption is a tsunami, powerful walls of water that reached over a hundred feet high at the Krakatoa eruption in 1883. Not only was water was an issue with this tsunami, rocks from the volcano also came down and endangered countless lives. This mixture was enough force to bring down a light house that was reinforced with steel, leaving nothing but the foundation in its wake. However the one upside of the volcanoes erupting is the creation of Volcanology, the study and predictions of volcanoes.
