Earthquake

An earthquake (also known as a quake, tremor or temblor) is the result of a sudden release of energy in the Earth’s crust that creates seismic waves. The seismicity or seismic activity of an area refers to the frequency, type and size of earthquakes experienced over a period of time. Earthquakes are measured using observations from seismometers. The moment magnitude is the most common scale on which earthquakes larger than approximately 5 are reported for the entire globe. The more numerous earthquakes smaller than magnitude 5 reported by national seismological observatories are measured mostly on the local magnitude scale, also referred to as the Richter scale. These two scales are numerically similar over their range of validity. Magnitude 3 or lower earthquakes are mostly almost imperceptible and magnitude 7 and over potentially cause serious damage over large areas, depending on their depth. The largest earthquakes in historic times have been of magnitude slightly over 9, although there is no limit to the possible magnitude. The most recent large earthquake of magnitude 9.0 or larger was a 9.0 magnitude earthquake in Japan in 2011 (as of March 2011), and it was the largest Japanese earthquake since records began. Intensity of shaking is measured on the modified Mercalli scale. The shallower an earthquake, the more damage to structures it causes, all else being equal.

At the Earth’s surface, earthquakes manifest themselves by shaking and sometimes displacement of the ground. When the epicenter of a large earthquake is located offshore, the seabed may be displaced sufficiently to cause a tsunami. Earthquakes can also trigger landslides, and occasionally volcanic activity.
In its most general sense, the word earthquake is used to describe any seismic event — whether natural or caused by humans — that generates seismic waves. Earthquakes are caused mostly by rupture of geological faults, but also by other events such as volcanic activity, landslides, mine blasts, and nuclear tests. An earthquake’s point of initial rupture is called its focus or hypocenter. The epicenter is the point at ground level directly above the hypocenter.

Present Continuous Tense

Present Continuous Tense  The continuous and progressive aspects (abbreviated CONT and PROG) are grammatical aspects that express incomplete action in progress at a specific time: they are non-habitual, imperfective aspects. It is a verb category with two principal meaning components: (limited) duration and (possible) incompletion. Most languages treat continuous and progressive aspects as alike and use the two terms interchangeably, but there are languages that distinguish them. (http://en.wikipedia.org/wiki/Present_continuous) The Present Continuous which is also known as present progressive is used to tell actions going on at the moment of speaking and for actions taking place only for a short period of time. It is also used to express development and actions arranged for the near future. The present progressive emphasizes on the course or the duration of an action. The Patterns Affirmative Subject+be (am,is,are)+ Verb-ing (present participle) ——>> I am doin...
