of energy released during an earthquake. It may be expressed using several magnitude scales. One of these‚ Used in Southern California‚ is called the Richter scale. To calculate magnitude‚ the amplitude of waves on a seismogram is measured‚ correcting for the distance between the recording instrument and the earthquake epicentre. Since magnitude is representative of the earthquake itself‚ there is thus only one magnitude per quake. Taking the Lawton earthquake of 1998 APR 28‚ as an example

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

A strong earthquake struck Friday off the coast of northeastern Japan in the same region that was hit by a massive earthquake and tsunami last year. A city in the region reported that a small tsunami had hit‚ but there were no reports of injuries or damage. The Japan Meteorological Agency said the earthquake had a preliminary magnitude of 7.3 and struck in the Pacific Ocean off the coast of Miyagi prefecture at 5:18 p.m. (0318 Eastern). The epicenter was 6.2 miles beneath the seabed. After the

What is a disaster? Disaster‚ in this article‚ a sudden‚ accidental event that causes many deaths and injuries. Most disasters also result in significant property damage. Common natural causes of disasters include earthquakes‚ floods‚ hurricanes and typhoons‚ and tornadoes. Tsunamis (popularly‚ but incorrectly‚ known as tidal waves)‚ volcanic eruptions‚ wildfires‚ and landslides and avalanches rank among the other natural forces that sometimes create disasters. Man made Not all disasters are

Claveria‚ Noveamie C. San Andreas The San Andreas movie is a good movie and a nice wake up call for everyone. I’m very thankful that this movie is released in time for the earthquake preparedness of our country. You might get tips on how to survive or maybe get tips on how you can die if you don’t prepare for it. I watched this film in our classroom during our Science subject. I enjoy ed the movie because everyone shouting “aaaaahhhhh” whenever there’s explosion and destruction hahaha. The action
