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, seismism 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 Richterscale. 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.

In this special issue, we are going to invite front-line researchers and authors to submit original research and review articles that explore Earthquake. Potential topics include, but are not limited to:

l Naturally occurring earthquakes
l Size and frequency of occurrence
l Induced seismicity
l Effects of earthquakes
l Measuring and locating earthquakes

Before submission authors should carefully read over the journal’s Author Guidelines, which are located at http://www.scirp.org/Journal/ForAuthors.aspx?JournalID=69.

Prospective authors should submit an electronic copy of their complete manuscript through the journalManuscript Tracking System at http://papersubmission.scirp.org/admin/initLoginAction.action?journalID=19
according to the following timetable:
