Have felt an earthquake before - also minor - and so recognized it."Sounded and felt like a really large truck going by. Had to take a moment to determine what was happening."Looked to the window to see if a truck went past on the lane and then noticed the water in the jug was gently sloshing back and forth - nothing else moving.

Eventful year."Dr Tony Knap at BIOS said that according to the seismometer at the site, the earthquake reached a magnatude of 4.6.The epicentre of the earthquake was 56 miles west northwest of the Island at a depth of around 10km."There are around 25,000 earthquakes recorded every year, and there have been around 307 last week," Dr Knap said."Most of them happen in the ocean simply because 70 percent of the Earth's surface is water, but we are a long way from a fault."Government issued a statement this afternoon saying: "At 12.50pm. the Bermuda Weather Service (BWS) received a phone call from the West Coast Alaska Tsunami Warning Centre, indicating that there was a 4.4 Magnitude Earthquake at 1538 UTC (12.38 local time), estimated to be 50 miles west of Bermuda."It was reiterated at the time that there was no tsunami danger, and the BWS quickly went about the business of alerting the relevant authorities to that fact, in addition to updating the www.weather.bm website, the Bermuda Weather Channels on the cable providers, and the automated phone tapes."In addition, the BWS was directly in touch with members of the public who called in to make reports directly. It should be noted that there were no official tsunami information statements, alerts, watches or warnings issued as a result of this event; there would not routinely be any urgent messages forthcoming for such a small magnitude earthquake, regardless of how close to land it occurs."Dr Mark Guishard, Director of the Bermuda Weather Service says: “During this event we were in touch directly with RCC Bermuda Radio, the Bermuda Police Service, the Emergency Measures Organization, and the Department of Airport Operations."Here's some useful weblinks:http://www.1.usa.gov/gWX3FGhttp://www.earthquake.usgs.gov/earthquakes/recenteqsww/Maps/10/295_30.phphttp://www.earthquake-report.com/2011/04/17/earthquakes-list-april-18-2011/COMMENTSThese are some of the comments posted on our Facebook pages and from emails to us:Marcus Proctor emailed to say: "I was chillin with my boys at the Berkeley Institute when I started to feel the ground shake and the table shook also, and also heard rumblings."Anneisha White said: "I felt and I was in my school's library at Berkeley for about 10 seconds…I was scared and confused."Carl Durrant said: "We were sitting in the living room talking and we felt this rumble.under our feet it lasted about 10 secs.
