Earthquake shakes UK: Is it something to worry about?February 27th, 2008 - 10:13 am ICT by amritpal
An Earthquake was experienced across the country in the early morning effecting at least six to seven counties. Apparently, it was measured 4.7 at Richter scale and by that parameter has been one of the biggest earthquakes ever to hit the UK. No reports of injuries or property damage have been reported yet. However, it is possible that such news may surface up later especially when after shocks take place. The Britons are shaken up by the Earthquake as it is a rare phenomenon in this part of the world.
Historically rare, but the larger UK earthquakes have caused significant damage to older buildings with poor foundations and structure. Tidal waves flooding towns and sinking ships have even been recorded associated with UK earthquakes. If an Earthquake is Under 6.0 it can cause at most slight damage to well-designed buildings and can cause major damage to poorly constructed buildings over small regions.
Technically, An earthquake is the result of a sudden release of energy in the Earth’s crust that creates seismic waves. Earthquakes are recorded with a seismometer, also known as a seismograph. The moment magnitude of an earthquake is conventionally reported, or the related and mostly obsolete Richter magnitude, with magnitude 3 or lower earthquakes being mostly imperceptible and magnitude 7 causing serious damage over large areas. Intensity of shaking is measured on the modified Mercalli scale.
At the Earth’s surface, earthquakes manifest themselves by a shaking and sometimes displacement of the ground. When a large earthquake epicenter is located offshore, the seabed sometimes suffers sufficient displacement to cause a tsunami. The shaking in earthquakes can also trigger landslides and occasionally volcanic activity.
