Why you need to prepare for the next earthquake . Alaska has more earthquakes than any other region of the U.S. . And in fact is one of the most seismically active area of the world.. Great earthquakes (Earthquakes larger than magnitude 8) rock the state on average every 13 years since the 1900. .
. By : . Deavian. foster . Class : 5H. What is an earthquake?. A earthquake is a shaking of the earths crust and is a geological phenomenon . Earthquakes can cause intense vibration of the ground, soil liquefaction, and distortion of the ground. Earthquakes can happen almost anywhere but are most common along the boundaries of the tectonic plates. Earthquakes are primarily caused of movement of the tectonic plates. It lasts more than a few seconds..
They Shape Our Landscape. As plates move, we may feel these movements as earthquakes. If there were no plate motions, our planet would not look like home. There would be no mountains, no valleys, no plateaus .

Chapter 2 Section 3. Objectives. F.2.3.1. Explain how a seismograph works.. F.2.3.2. Describe how Geologists monitor faults.. F.2.3.3. . Explain how . seismograph data is used.. The Seismograph. Seismic waves cause the seismographs drum to vibrate but the suspended weight with the pen attached moves very little. Therefore the pen remains still and records the vibrations on the drum..

By. : 10 grade. What is an earthquake ?. Simply, earthquakes are the rumblings, shaking or rolling of the earth's surface. It is usually what happens when two blocks of the earth suddenly slip past one another, or break apart from each other as a result of tension caused by prolonged energy build up. .
Content Purpose:. Explore the scientific theory of plate tectonics by describing how the movement of Earth's crustal plates causes both slow and rapid changes in Earth's surface, including volcanic eruptions, earthquakes, and mountain building. .
