Not sure if anyone saw this?  Good news IMHO.

The Italians have been locking up scientists for centuries ,must be something in the water ,good news all the same ....

Tectonic Summary Seismotectonics of the Mediterranean Region and Vicinity

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.

A magnitude-6.5 earthquake struck off the coast of eastern Indonesia on Friday, the U.S. Geological Survey reported on its website.

The quake occurred at 6:10 p.m. (local time) and caused considerable shaking on land, but there was no sign of a tsunami, Kyodo News reported, citing a text message from a spokesman for Indonesia'sNational Disaster Mitigation Agency.

The USGS said the quake's epicenter was at sea, 161 kilometers north northwest of Ternate.

There were no immediate reports of damage or injuries, Kyodo reported.

[john pike]

A 5.8-magnitude earthquake jolted Kangding county, Ganzi Tibetan Autonomous Prefecture in Sichuan province at 11:19 p.m. on Tuesday, three days after the same area was devastated by a 6.3-magnitude quake that resulted in five deaths and dozens of injuries. The epicenter was monitored at a latitude of 30.2 degrees north and a longitude of 101.7 degrees east. The quake hit at a depth of 16 kilometers, with three people slightly injured, according to the China Earthquake Networks Centre said earlier this morning. Many local residents rushed out of their homes to the streets and a gymnasium after the quake. Zhao Ming, the director of the China Earthquake Emergency Rescue center, said the quake was around 10 km in distance to the previous one. Whether the earthquake was an entirely separate one or an aftershock hasn't been confirmed yet.

that's deep John , convective magma on the move perhaps ?...

hi mokid

have a read of that

 

unfortuanately its one of the great unknowns

 

but magma on the move could be possible too

Earthquakes are still ongoing strongly even though if you hear the news nothing`s going on,move along.

It did briefly mention the 6.9 quake in japan the other day.

But 7.1 earthquake in the mid atlantic ridge on the 14th is the strongest one I`ve seen there.

Interesting write-up on the earthquake. Only one other mag 7 in the last hundred years, exactly the same date but 48 years ago!

 

 

The February 13, 2015 M 7.1 Northern Mid-Atlantic Ridge earthquake occurred as the result of right-lateral strike-slip faulting on or near a transform fault forming part of the North America:Eurasia plate boundary.  At the latitude of this earthquake, the North America plate moves approximately westward at a rate of 21 mm/yr with respect to Eurasia. The preliminary location and mechanism of the earthquake are consistent with its occurrence on the Charlie-Gibbs Transform (the seismically active section of the Charlie-Gibbs Fracture Zone), though more detailed analyses of the event will be required to definitively determine the causative structure.

Moderate-to-large earthquakes in this region of the north Atlantic are not uncommon – over the past century, five other earthquakes of M 6.3-7.0 have occurred within 250 km of the February 13, 2015 event, likely along the same fracture zone. The largest of these was a M 7.0 event on the same day in 1967, 48 years before today’s M 7.1 earthquake. Because of their strike-slip mechanisms and locations in the remote north Atlantic, none of these historic events are known to have caused damage.

Saw this interesting article linking beachings with future quakes.

 

Could Japan be set for a big quake in the next few days?
