Anyone remember this? http://en.wikipedia.org/wiki/2008_Lincolnshire_earthquake

 

Can't believe it is 6 years ago in Feb where has the time gone? Anyway I recall just going to bed at almost 1am (I've always gone bed late), put my earphones in to relax and all of a sudden my bed began to move and it felt like someone was gently pushing me so I took my earphones out and noticed my wardrobe rocking a bit and an object fell of it. 

 

Was a surreal but interesting experience.

was not sure where to post this

 

however as it involves land movement i thought here was the right place

 

East Antarctica is sliding sideways
by Staff Writers
San Francisco CA (SPX) Dec 12, 2013

File image.

It's official: East Antarctica is pushing West Antarctica around. Now that West Antarctica is losing weight--that is, billions of tons of ice per year--its softer mantle rock is being nudged westward by the harder mantle beneath East Antarctica.

The discovery comes from researchers led by The Ohio State University, who have recorded GPS measurements that show West Antarctic bedrock is being pushed sideways at rates up to about twelve millimeters--about half an inch--per year. This movement is important for understanding current ice loss on the continent, and predicting future ice loss.

They reported the results on Thursday, Dec. 12 at the American Geophysical Union meeting in San Francisco.

Half an inch doesn't sound like a lot, but it's actually quite dramatic compared to other areas of the planet, explained Terry Wilson, professor of earth sciences at Ohio State. Wilson leads POLENET, an international collaboration that has planted GPS and seismic sensors all over the West Antarctic Ice Sheet.

The 5.1-magnitude earthquake that jolted a county in central China's Hubei Province Monday injured six people and forced more than 2,000 to be relocated, authorities said Wednesday. The quake hit the mountainous Badong County in Enshi Tujia and Miao Autonomous Prefecture at 1:04 p.m. Monday, according to the China Earthquake Networks Center. It destroyed or damaged the homes of more than 5,000 households, disrupting 30,000 people in 12 townships in the counties of Badong, Zigui and Xingshan, according to a written statement issued by the provincial civil affairs department. Direct economic losses reached 37.51 million yuan (6.2 million U.S. dollars), said the statement. The department has sent 100 tents, 3,500 quilts and 3,500 pieces of cotton clothing to the quake-hit zone.

Seismotectonics of the Middle East and Vicinity

No fewer than four major tectonic plates (Arabia, Eurasia, India, and Africa) and one smaller tectonic block (Anatolia) are responsible for seismicity and tectonics in the Middle East and surrounding region. Geologic development of the region is a consequence of a number of first-order plate tectonic processes that include subduction, large-scale transform faulting, compressional mountain building and crustal extension.

Mountain building in northern Pakistan and Afghanistan is the result of compressional tectonics associated with collision of the India plate moving northwards at a rate of 40 mm/yr with respect to the Eurasia plate. Continental thickening of the northern and western edge of the India subcontinent has produced the highest mountains in the world, including the Himalayan, Karakoram, Pamir and Hindu Kush ranges. Earthquake activity and faulting found in this region, as well as adjacent parts of Afghanistan and India, are due to collisional plate tectonics.

Beneath the Pamir-Hindu Kush Mountains of northern Afghanistan, earthquakes occur to depths as great as 200 km as a result of remnant lithospheric subduction. Shallower crustal earthquakes in the Pamir-Hindu Mountains occur primarily along the Main Pamir Thrust and other active Quaternary faults, which accommodate much of the region's crustal shortening. The western and eastern margins of the Main Pamir Thrust display a combination of thrust and strike-slip mechanisms.

Along the western margin of the Tibetan Plateau, in the vicinity of southeastern Afghanistan and western Pakistan, the India plate translates obliquely relative to the Eurasia plate, resulting in a complex fold-and-thrust belt known as the Sulaiman Range. Faulting in this region includes strike-slip, reverse-slip and oblique-slip motion and often results in shallow, destructive earthquakes. The relatively fast moving left-lateral, strike-slip Chaman Fault system in southeastern Afghanistan accommodates translational motion between the India and Eurasia plates. In 1505, a segment of the Chaman Fault system near Kabul, Afghanistan ruptured causing widespread destruction of Kabul and surrounding villages. In the same region, the more recent 30 May 1935, M7.6 Quetta, Pakistan earthquake, occurred within the Sulaiman Range, killing between 30,000 and 60,000 people.

They were probably felt very locally John.  Going by the depth, I'd say it was a collapse of old mine workings as there are many in that particular area.  Most of the pits over there were deep mine pits.

The precise causes of quakes in the UK are often hard to determine, as the country is not close to any active tectonic margins but subject to stresses from a number of different sources, with most tremors probably being caused by a combination of these. Britain, along with the rest of Europe, is being pushed to the east by the expansion of the Atlantic Ocean, and to the north by the movement of Africa from the south. There are also lesser spreading centers beneath the North Sea, the Rhine Valley and the Bay of Biscay, which all exert tectonic stress upon rocks in the UK. Finally there is glacial rebound; up until about 10 000 years ago much of the north of the UK was covered by hundreds of meters of ice. This pushed the rocks of the British Lithosphere down into the underlying mantle, and now this ice is gone these rocks are slowly rebounding, producing a source of minor Earthquakes.

 

our quakes are normally related to other parts of the world or the north shifting around

 

was just curious to be honest to see if anyone had felt this

 

have a very happy christmas

activity on the increase today

M5.8 - 80km SSW of Avsallar, Turkey

the Mediterranean region is seismically active due to the northward convergence (4-10 mm/yr) of the African plate with respect to the Eurasian plate along a complex plate boundary. This convergence began approximately 50 Ma and was associated with the closure of the Tethys Sea. The modern day remnant of the Tethys Sea is the Mediterranean Sea. The highest rates of seismicity in the Mediterranean region are found along the Hellenic subduction zone of southern Greece, along the North Anatolian Fault Zone of western Turkey and the Calabrian subduction zone of southern Italy. Local high rates of convergence at the Hellenic subduction zone (35mm/yr) are associated with back-arc spreading throughout Greece and western Turkey above the subducting Mediterranean oceanic crust. Crustal normal faulting throughout this region is a manifestation of extensional tectonics associated with the back-arc spreading. The region of the Marmara Sea is a transition zone between this extensional regime, to the west, and the strike-slip regime of the North Anatolian Fault Zone, to the east. The North Anatolian Fault accommodates much of the right-lateral horizontal motion (23-24 mm/yr) between the Anatolian micro-plate and Eurasian plate as the Anatolian micro-plate is being pushed westward to further accommodate closure of the Mediterranean basin caused by the collision of the African and Arabian plates in southeastern Turkey. Subduction of the Mediterranean Sea floor beneath the Tyrrhenian Sea at the Calabrian subduction zone causes a significant zone of seismicity around Sicily and southern Italy. Active volcanoes are located above intermediate depth earthquakes in the Cyclades of the Aegean Sea and in southern Italy.

Iranian state TV says a magnitude 5.5 earthquake has killed one person and injured 12 in a small town in the country's south. The report says the quake struck early on Thursday morning in the town of Bastak, about 1,200 kilometers (750 miles) south of the capital, Tehran. It says many of the town buildings were damaged and that rescue workers were on the scene. Iran sits on a series of seismic fault lines and experiences one slight quake a day on average.

[john pike]

A strong earthquake out to sea has shaken Puerto Rico's northern coast, causing minor damage in some places. Dozens of people reported fallen items in their home and feeling buildings sway in the capital of San Juan, about 59 miles (96 kilometers) from the quake's epicenter. The U.S. Geological Survey said the quake had a preliminary magnitude of 6.5 and struck just after midnight about 34 miles (56 kilometers) north of Hatillo. It said the quake occurred 17 miles (28 kilometers) deep. Puerto Rico's emergency management agency said there was no tsunami warning.

coast i think the size of this was worth reporting

 

not quite sure your report showing is correct re no human impact

 

A strong earthquake  struck Northern Puerto Rico early Monday about 34 miles north of Hatillo municipality and caused minor damages including some power outages and floor cracks.  No injuries have been reported so far. The earthquake is one of the largest quakes to hit the U.S. territory in recent years.

The U.S. Geological Survey said the earthquake was out at sea and estimated its magnitude to be about 6.4. The survey also revealed the quake went approximately 17 miles deep.

A geologist with Puerto Rico’s Seismic Network, Gisela Baez Sanchez, said at least 70 aftershocks of 3.5 or more magnitude have since been reported.

People living along the coast reported cracked walls and floors, broken windows and  busted water lines. Authorities confirmed that power outages mostly occurred in the northern city of Bayamon which is next to Puerto’s capital of San Juan. Some people, however, reported buildings swaying in San Juan, about 61 miles (98 kilometers) from the epicenter of the quake.

The island’s government was criticized in the social media for not issuing a tsunami alert immediately after the quake. However, authorities have defended themselves saying they would have done so had there been risk of injuries.

According to Puerto Rico’s emergency management agency spokesman, Carlos Acevedo, many people called the emergency services but no injuries have been reported. As a result, the agency has not issued a tsunami alert yet since the damages have been minor.

“No one has required our services.†Carlos Acevedo said in a phone interview.

The last time Puerto Rico experienced an earthquake of a similar magnitude was in 1918 when a 7.3 magnitude earthquake hit the island and killed 116 people. In 2011, there was also a 5.4 magnitude quake that shook the island and followed by another, occurring in Dec 2010.
