crust. In some cases, the energy can be intense enough that it is felt in the form of an earthquake, while in other seismic events, the energy is so mild that it can only be identified with specialized equipment. A human disaster is an event directly and principally caused by one or more identifiable deliberate or negligent human action. Whereas a natural disaster is a natural event such as a flood, earthquake, or hurricane that causes great damage or loss of life. A disaster is often considered a

Earthquakes Christina OBanion Instructor Kryger SCI/245 February 28, 2010 Earthquakes have been happening for a long time, but now we are able to help detect where and possibly when these events might happen. They now seem to be getting stronger than they were in the past and even more frequent. No matter when or where earthquakes happen people always need to be aware that they have the potential to be devastating for those close by, or even those who are on the other side of the world.

Generally, earthquakes are sudden vibrations that happen on the earth’s crust which are caused by a number of factors. The movement of earths plate is what constitutes an earthquake and leads to various effects to the part of the earth it is experienced. The magnitude or the measure of the effects that an earthquake can cause is measured by a scale called Richter scale. To start with, the first cause of earthquakes is the release of undue pressure that builds in the underground rocks of the earth

[Student Name] [Course Title] [Supervisor Name] [Date] Tsunamis Tsunamis are caused by earthquakes, landslides and sometimes by volcanic eruption. Most commonly they are caused by earthquakes that causes disturbance below the ocean floor as they occur. This further moves water up to the surface creating large waves. These large waves are hundred of feet high and are known as tsunami. In the middle of the sea these waves are not that large but as they approach the shores they get very dangerous

From Earthquakes to Tsunamis Canada’s West Coast which is home to beautiful British Columbia, has experienced a fault line issue which created more earthquakes with magnitudes greater than any other of the provinces and territories. Out of the 4000 earthquakes that happen per year in Canada, scientists at the Geological Survey of Canada stated that there are “approximately 1000 earthquakes each year in western Canada” (Lyons, 2013). The most seismic earthquakes happen on the shore of Vancouver

Introduction Every Californian resident knows what the phrase “The Big One” means: a tremendous earthquake that scientists predict will rock the state of California, which sits on the famous San Andreas Fault line, an 800-mile line of weakness that runs through California. Overland, it runs for 625 miles, running north-south from Point Arena in north San Francisco to the border with Mexico. The most risky stretch of this fault, the southern part, passes about 35 miles from Los Angeles. Being the

Earthquakes xxxxx SCI245 September 18, 2011 There are four types of tectonic plate margins, the meeting place of one plate with another. The four plates are destructive, constructive, collision, and conservative. Plates are constantly moving or changing position. The divergent boundaries are where new crust is generated as the plates pull away from each other. The convergent boundaries are where the crust is destroyed as one plate drives under another. The Transform boundaries are
