Earthquakes An earthquake is a shaking or trembling of the crust of the earth caused by underground volcanic action or by the breaking and shifting of rock beneath the surface. The volcanic action and shifting rocks create strain which continues to build to a sudden release of pressure resulting in a shock wave. The vibrations produced in the crust can vary from barely noticeable to enormously destructive. Shock waves can be classified into two broad categories. Waves that send particles oscillating

Earthquakes By: Kayla Marie Vargas Period 4 In earth science they talk a lot about different Earthquakes‚ volcanoes‚ the weather‚ different rocks‚ and etc. But never did you really get in details of what is any of them. Well I did research and found out that an earthquake which is also known as a quake‚ tremor or temblor is a result of a sudden release of energy in the Earth’s crust that creates seismic waves. The seismicity‚ seismism or seismic activity of an area refers to the frequency

EARTHQUAKE Introduction An earthquake is the result of a sudden release of energy in the Earth’s crust that creates seismic waves. CAUSE OF EARTHQUAKE Earthquakes are caused by the movement of the earth’s tectonic plates. Earthquakes occur where the earth’s plates meet along plate boundaries (see plate tectonics page for more information on this).For example as two plates move towards each other‚ one can be pushed down under the other one into the mantle. If this plate gets stuck it

EARTHQUAKES o Plates sliding pass each other create friction o Friction builds up creating stress (a force) o Force is greater than plate can withstand‚ budges and breaks‚ creating earthquakes o Release a lot of energy KEY TERMS Seismology- the study of earthquakes and their effects Seismometer/ Seismograph - equipment measuring the amount of ground motion caused by an earthquake ***Let’s do a demo*** Seismogram- record of ground motion produced

Earthquakes are one of the most destructive natural disasters. It is when the stored energy beneath the Earth’s surface is discharged and shakes the ground. The impact of this event is one of the most traumatic ones because it can put long term effects on a large area. They are proven to be unpredictable but once it strikes‚ all in a few seconds‚ cities and towns are completely flattened. Continue on to discover more about this dangerous calamity. Did you ever know that the earth can also move

Earthquakes are one of the most destructive of natural hazards. Earthquake occurs due to sudden transient motion of the ground as a result of release of elastic energy in a matter of few seconds. The impact of the event is most traumatic because it affects large area‚ occurs all on a sudden and unpredictable. They can cause large scale loss of life and property and disrupts essential services such as water supply‚ sewerage systems‚ communication and power‚ transport etc. They not only destroy villages

Loma Prieta Earthquake Story Teller By: Kavita Butani There is a lot that happens around the world we cannot control. We cannot stop earthquakes‚ we cannot prevent droughts‚ and we cannot prevent conflict. Earthquakes and the damages they bring have affected the lives of many people around the world forever. As our community grows so does the danger caused by these quakes also increases by mass. Earthquakes can affect our lives in many ways; this type of natural disaster can upset everything from
