Rutland was hit by its strongest earthquake in 13 years this morning.
The 3.2-magnitude earthquake, powered from a depth of 2.5 miles, struck the Oakham area at 7.07am.
"There was a 4.1 in Melton Mowbray in October 2001 - so this is the biggest in the region for 13 years.
"It was quite widely felt but we probably get about three of these at this size somewhere in the UK each year.
"We record about 200 earthquakes and it is to do with the earth's dynamic plates moving, probably about the pace of the growth of a fingernail.
"The most common reports we have had is that houses shook, windows rattled for quite a few seconds, people were quite alarmed.
"We do not get the big earthquakes like they would get in places like Japan."
It was felt up to 28 miles (45 km) away from the epicentre of the earthquake near Wellingborough but most reports have come in from people who are within 15 miles (25km) of Oakham. Residents in parts of Stamford, Kettering and Oakham went online to say they felt the earthquake.
The UK's most powerful earthquake was the 5.4 magnitude tremor which hit the Lleyn peninsula in north Wales in July 1984 and in 2008 a quake centred on Market Rasen, Lincolnshire, was measured at 5.2.
