lines, the greater the felt shaking was at that location. But wait, you may ask, I thought you said this quake was caused by That depends.

Along with those other aforementioned factors, the relative shallowness of the quake probably had something to do with the widespread nature of the not-insignificant shaking.There are plenty of reports coming of minor structural damage, power outages, people trapped in elevators and minor injuries – but, so far, there haven't been any reports of any major injuries or deaths. More than 100 buildings (including three major factories) … As it has been for 50 million years or so, the African tectonic plate is moving toward the Eurasian plate, something that once ended up closing up a sea known as the Tethys, whose contemporary remnants can be found in the form of the Mediterranean Sea.The plate boundary here is pretty complicated: it’s produced a earthquake-prone subduction zone, where one plate sinks under another, in southern Greece; you also have the North Anatolian Fault Zone in western Turkey, itself home to both devastating and The so-called Hellenic subduction zone may involve two plates squishing into (and over-and-under) each other, which causes compression in parts of this region. In mainland Greece, normal faulting gives earthquakes up to 7 in magnitude, while in the northern Aegean, strike-slip events with a magnitude of 7.2 have been recorded.
Anything weaker that happened before in the same cluster is known as a foreshock, and anything weaker afterwards is known as an aftershock.There have already been a few aftershocks rocking the region, with one coming in at a I’ll update this post if an aftershock forecast comes in, but in general, the mostly likely pattern remains somewhat similar. Large intermediate depth (>50 km) earthquakes of magnitude >7 from within the subducting African Plate have been recorded but such events cause little damage, although they are widely felt. Earthquakes don’t happen in isolation, but in clusters, as faults tend to keep jutting forwards after letting loose over time, freed up a little after that initial big push. You can get in touch with him at robingeorgeandrews.com.Opinions expressed by Forbes Contributors are their own. Depending on how and when seismometers Magnitude relates to the amount of energy that a rupturing fault (or faults) unleash during the duration of their rupture.

In mainland Greece, normal faulting gives earthquakes up to 7 in magnitude, while in the northern Aegean, strike-slip events with a magnitude of 7.2 have been recorded. Greece is located at the complex boundary zone in the eastern Mediterranean between the These two plate boundaries give rise to two contrasting tectonic styles, The strongest earthquakes historically are those associated with the Hellenic Arc, although none larger than about 7.2 have been observed instrumentally. Athens has had: (M1.5 or greater) 0 earthquakes in the past 24 hours 0 earthquakes in the past 7 days; 0 earthquakes in the past 30 days; 5 earthquakes in the past 365 days It occurred at a depth of 10 kilometres (6.2 miles). At that magnitude and shaking intensity near several metropolitan areas, it’s not surprising that damage has occurred; the The US has an automated system that, based on magnitude, intensity and other factors, estimates the potential number of deaths and the At the moment, the magnitude 5.3/5.1 event looks like the mainshock, although we’ll have to wait a little to make sure this is the case. The same uptick in reporting will happen for any quakes that In any case, major earthquakes aren't more or less common than they were a week, a year, a decade or a century ago. If you think they are becoming more common, it's just because they're being reported on more at the moment by the media. The 1999 Athens earthquake occurred on September 7 at 14:56:51 local time near Mount Parnitha in Greece with a moment magnitude of 6.0 and a maximum Mercalli intensity of IX (Violent). Consequently, the media is on the lookout for any other quakes of significant magnitude to report on.
As ever, I'll update this post if new, relevant, verified information comes in.The quake struck north of Athens – specifically, three kilometres (two miles) north-northwest of Magoula, or roughly 22 kilometres (14 miles) north of the capital. Coming it an a magnitude 5.3, according to the United States Geological Survey (USGS)’s Small differences in magnitude early on are common: They are calculated based on the amplitude (the maximum height of depths of a wibbly wave) of the seismic waves emanating from the quake’s hypocentre, its point of origin below ground.
