answer is that earthquakes are caused by faulting‚ a sudden lateral or vertical movement of rock along a rupture (break) surface. Here’s the longer answer: The surface of the Earth is in continuous slow motion. This is plate tectonics--the motion of immense rigid plates at the surface of the Earth in response to flow of rock within the Earth. The plates cover the entire surface of the globe. Since they are all moving they rub against each other in some places (like the San Andreas Fault in California)

A Discussion On Earthquakes Perhaps Mother Nature offers no greater force than that of the earthquake. Across the span of time‚ earthquakes have been recorded for their incredible destructive forces‚ and their abilities to awe mankind with their unparalleled force. Earthquakes can often strike without any notice‚ leveling large cities and killing scores of innocent people. Not only can earthquakes bring harm to society through these methods of destruction‚ but they can also cause millions

The Alpine Fault Investigate the evidence relating to geological event(s) Micheal Munro AS91412 Intro The Alpine fault is the boundary of the Pacific oceanic plate and the continental Australian plate. It is located almost through the entire south island of New Zealand extending about 600 Km across it1. It is one of the world’s major geological features and is responsible for the amazing Southern Alps. Each time it has ruptured it has moved both vertically as well as horizontally. Some believe

Constructive boundaries occur when two plates move apart which causes new oceanic crust to be formed and mid-ocean ridges are created by the build-up of molten rock on the seafloor due to the mantle building up. This new crust pushes the old crust aside and forcing the plates apart at a very slow rate. Basaltic lava rises which means new crust is being added continuously. Rift valleys are formed at constructive boundaries‚ where convection current causes the crust to be pulled apart causing fractures

Haiti is the most impoverished country in the Western Hemisphere‚ and amongst the poorest in the world. With that being said‚ when an earthquake happened just kilometres away from Haiti’s capital of Port-au-Prince‚ the country was hardly prepared (Fierro & Perry‚ n.d.). Haiti has overcome various natural disasters‚ including hurricanes‚ tsunamis‚ floods‚ landslides‚ and other tropical storms. Haitians expect these natural hazards to occur‚ due to past events and the location of the country making

100 4/15/13 Japan earthquake On March 11‚ 2011‚ Japan was hit by a magnitude 9.0 quake at about 2:50 pm. This would turn out to be the largest earthquake in the past thousands years to ever be recorded. What caused this massive destruction one might ask? This devastating quake was caused because Japan is located between two major tectonic plates. When a large number of plate movements occur‚ the Pacific Plate makes its way below a subduction zone. When plate movements are not gradual

RAPPEL A L’ORDRE: THE CASE FOR THE TECTONIC Kenneth Frampton Kenneth Frampton’s ‘Rappel a L’Ordre: The Case for the Tectonic’ identifies the issues in relation to the tectonic form‚ his intention is to make architecture step apart of just being part of a scenographic interpretation. The word tectonic is addressed from its different origins but overall referring to carpentry and its evolution into an aspect of poetry and art of construction. Tectonic objects are seen in two different forms;

Volcanic and seismic events are major pieces of evidence towards proving that the plate tectonics theory is valid. The theory of tectonic plates was first posed by Alfred Wenger in 1912. Is the theory of how the earth lithosphere is made up of many separate pieces of the earth’s crust known as tectonic plates. He put forward the idea that all the earth’s continents were once conjoined in one supercontinent called Pangaea‚ and that these continents were moved by convection currents over a period

‘Evaluate how plate tectonics theory helps our understanding of the distribution of seismic and volcanic events’ In 1912‚ Alfred Wegener published his theory that a single super continent named Pangaea once existed about 300 million years ago. He proposed that Pangaea then later split into two continents of Laurasia in the north and Gondwanaland in the south and that today’s continents were the result of further splitting of these two land masses. Where the plates split are known as plate boundaries
