Earthquake at 1am!!!
Posted by Kushal | Filed under Uncategorized
Damn, that was a powerful one. Obviously small, based on Hollywood standards but powerful for ours.
The House creaked, the walls shook, plates vibrated and people shat them selves.
At around 1.20am Sky News reported a measurement of 4.7 by the United States Geographical Society.
The Who? I’ve found the US Geological Survey who have also measured the earthquake at 4.7 but I can’t find this geographic society that measures earthquakes. Why is a geographical society measuring earthquakes? Shouldn’t they be making maps or something?
I filled in the "Report it" form on the USGS website about the quake. You have to fill in a multiple choice form. One of the questions is Did furniture or appliances slide, tip over, or become displaced? and the first possible answer is "No Furniture". !!?! Who has no furniture?
Just for the record, here are the facts:

The British Geological Survey disagree and feel it was a magnitude 5.2:
PRESS RELEASE
27 February 2008
England hit by Earthquake
The British Geological Survey (BGS) recorded an earthquake with a magnitude of 5.2 (ML) on the Richter scale near Market Rasen, Lincolnshire at 00:56 GMT. The BGS has been inundated with calls from the public, media and emergency services throughout England.
Summary:
DATE : 27 February 2008
ORIGIN TIME : 00:56 GMT
LAT/LONG : 53.42 ° North / 0.35 ° West
GRID REF : 509.4 kmE / 392.7 kmN
DEPTH : 5.0 km MAGNITUDE : 5.2 Richter Scale (ML)
LOCALITY : Market Rasen, Lincolnshire
The epicentre is approximately 4 km north of Market Rasen and reports suggest that the earthquake has been felt widely across England, with reports of damage to chimneys in the epicentral area. Earthquakes of this size occur in the mainland UK roughly every 30 years, although are more common in offshore areas. This is the largest earthquake in the UK since the magnitude 5.4 ML Lleyn Peninsula earthquake in 1984, which was widely felt across England and Wales.
Seismologist Dr Brian Baptie of the British Geological Survey said:
"The is a significant earthquake for the UK and will have been widely felt across England and Wales".
The BGS records approximately 200 earthquakes in the UK each year on its monitoring stations. Approximately 25 earthquakes in the UK are felt by people each year.
