Exploring Seismology The study of earthquakes and the structure of the earth, by both naturally and artificially generated seismic waves. An earthquake is defined as the vibration of the Earth’s surface by sound or shock waves usually generated by the energy released from rocks rupturing under stress or by friction between moving rock materials at or mostly below Earth’s surface. A seismologist is a scientist who studies earthquakes and seismic waves. CHAPTER 1 - What Are Seismic

In seismology, there are several types of waves studied, each of these waves have characteristics that define them. Seismic waves can be split into two categories, and they are body waves and surface waves. Body waves travel and move within the earths subsurface and inner layers. There are two types of body waves, P-Waves also known as compressional waves or primary waves, and S-Waves also called secondary or shear waves. The S-Waves have a vertical (Sv) and horizontal (Sh) component. “In an infinite

Earthquakes: How they happen and what to expect. What is an Earthquake? Have you ever wondered how it starts and what causes it? Many people spend everyday studying this to find answers. In theory scientists do know that an earthquake is the shaking of the ground caused by sudden release of energy inside the earth's crust. This is also known to scientists as the breaking and moving of tectonic plates along a fault line, which than creates seismic waves at the epicenter. The earthquake has

Seismic Resolution The definition of the term thin bed involves the concept of the resolving power (Widess, 1973) thus seismics is impacted by resolution. Most geological structures have a smaller vertical dimension than a horizontal one (Chang et al, 1996), thus, the ratio of the vertical dimensions plays a very important role in seismic resolution. As the dimension ratio decreases, the difficulty in identifying geological events increases and become more challenging (Chang et al, 1916). Sheriff

Earthquakes occur almost all over the world and often cause many casualties and injuries, but it is a common misconception to think that all earthquakes or even most of them cause destruction. In fact, most earthquakes aren’t even strong enough to be felt by humans and most animals, and can only be recorded by seismometers that are strategically placed in all corners of the world in order to get a reliable and precise reading on the earthquakes strength. Another common misconception about earthquakes

1906 San Francisco Earthquake Rachel Ziffer 3rd period At 5:12 a.m. on April 18, 1906, the people of San Francisco were awakened by an earthquake that would devastate the city. The earthquake was caused by a rupture of the northernmost 296 miles of the San Andreas Fault, leaving 225,000 homeless, 3,000 dead and 500 city blocks gone. This photograph, taken by George Lawrence from a series of kites five weeks after the great earthquake of April 18, 1906, shows the devastation brought on the city

Earthquakes have plagued our lives for as long as people have inhabited the earth. These dangerous acts of the earth have been the cause of many deaths in the past century. So what can be done about these violent eruptions that take place nearly with out warning? Predicting an earthquake until now has almost been technologically impossible. With improvements in technology, lives have been saved and many more will. All that remains is to research what takes place before, during, and after an earthquake

Disaster Warnings Just 20 seconds might save a life, a house or a school. The new regional earthquake warning system is designed to promote those 20 seconds that could save people from a disaster. The Earthquake Early Warning System can detect small to large earthquakes very quickly so that a warning could be sent out before destructive seismic waves arrive. It will also give a warning of the intensity of the shaking. These warnings would allow people to take protective actions, such as allowing

I chose to research earthquakes and the prediction of earthquakes because I was curious as to how they work. In this paper, I will discus the history of earthquakes, the kinds and locations of earthquakes, earthquake effects, intensity scales, prediction, and my own predictions. An earthquake can be defined as vibrations produced in the earth's crust. Tectonic plates have friction between them which builds up as it tries to push away and suddenly ruptures and then rebounds. The vibrations can range
