to every affected area. A hazard is any source of potential damage‚ harm or adverse health effects. A volcanic hazard is any threat to life and infrastructure due to volcanic activity and related situations such as a landslide near the volcano. Volcanoes can be very dangerous and therefore present many hazards towards both people and land. They have the ability to kill and destroy‚ ruining livelihoods and destroying large land masses. The extent of the hazard can differ depending on how prepared

represents the meaning of plates and boundaries. As an example of activity is an earthquake‚ which is caused by two plates like the Eurasian and pacific plate pushing towards each other‚ pushing the land upwards causing a mountain as well as an earthquake. The plates are pieces of land that make up the outer crust‚ these could move together‚ move apart or move alongside each other resulting in mountains‚ volcanoes and earthquakes‚ this happens deep below the surface and as the earth is spinning and moving

In the case of constructive plate boundary plate tectonic theory has helped our understanding as we can now determine that at constructive pate boundaries fissure volcanoes are more common here‚ therefore suggesting the nature of a potential eruption may not be as destructive as a

America. Mount Saint Helens is known to be one of the top 10 most famous volcanoes in the world due to the deadly pyroclastic flows and ash explosions well known to it. A volcano is a mountain with a vent at the top where magma and gasses from the earth’s Mantle erupt on the earths crust and turn into lava caused by the movement of the tectonic plates. Tectonic plates are big pieces of the lithosphere that

“Discuss the Extent to which volcanic and seismic activity are evidence for plate tectonic theory” (40) Plate tectonics is the theory that explains the structure and motion of the Earth’s lithosphere. The theory states that the Earth’s crust is split into large sections called tectonic plates‚ and these move relative to one another creating boundaries at which plates converge‚ diverge and move past each other. Alfred Wegener pioneered the theory of continental drift in the early 1900s which he supported

Areas such as California have high risk of earthquakes at any given moment. For years the western coast of the United States has had its fair share of experiences with earthquakes.

Pacific Ring of Fire (or just The Ring of Fire) is an area where a large number of earthquakes and volcanic eruptions occur in the basin of the Pacific Ocean. In a 40‚000 km (25‚000 mi) horseshoe shape‚ it is associated with a nearly continuous series of oceanic trenches‚ volcanic arcs‚ and volcanic belts and plate movements. The Ring of Fire has 452 volcanoes and is home to over 75% of the world’s active and dormant volcanoes.[1] It is sometimes called the circum-Pacific belt or the circum-Pacific seismic
