Aardbevingen treffen Lesbos en Turkse kust

ATHENE - De bewoners van het Griekse eiland Lesbos zijn maandag opgeschrikt door een serie aardbevingen. Ook aan de nabijgelegen Turkse kust voelden de mensen de grond trillen.

Drie bevingen hadden een kracht van rond de 5 en er waren ook nog acht bevingen met een kracht van tussen de 3 en 3,9. Volgens het Turkse persbureau DHA raakten in een dorp in de regio Ayvacik vijf mensen lichtgewond. Sommige huizen en schuren raakten beschadigd. De Griekse autoriteiten melden geen schade.

Het centrum van de reeks bevingen lag ongeveer 60 kilometer ten noorden van de stad Mytilene op Lesbos, op een diepte van 2 tot 12 kilometer.

Earthquake swarm hits western Turkey
A series of shallow and damaging earthquakes are shaking the tip of the Biga Peninsula in Western Turkey this month. The sequence includes four damaging M5+ earthquakes in which over 350 buildings sustained extensive damage. The quakes are occurring at the intersection of the Kestanbol Fault and the Edremit Fault Zone. ​

The strongest so far was M5.4 on February 6, 2017. This quake hit at a depth of 6 km (3.7 miles) at 13:08 UTC and was preceded by M5.2 at 08:36 UTC. The same area was hit by M5.3 at 08:08 UTC on February 7 and M5.0 at 13:55 UTC today. All quakes occurred at depths between 6 and 10 km (6.2 miles).

Since January 1, the region saw a total of 1 096 earthquakes, according to data provided by the EMSC. 879 of them occurred between February 1 and 12, and 841 between 00:19 UTC on February 6 and 13:55 UTC on February 12.

According to Volkan Sevilgen, Akın Kürēer and Hasan Elmacı (Temblor, MTA), the quakes are occurring at the intersection of the Kestanbol Fault and the Edremit Fault Zone.

As a result of the three damaging M5+ earthquakes, over 350 buildings sustained extensive damage. The Turkish Government has swiftly built a small village from container houses for those who needed shelter and asked residents not to enter any building before official building assessment.

"We calculated that the recent seismic swarm stressed the western portions of the Edremit Fault Zone by about 0.1 bar," the team wrote in their analysis.

"If we start seeing larger numbers of small earthquakes on the Edremit Fault Zone, it would suggest the fault was triggered by the seismic swarm. The last large earthquake on the Edremit fault was a magnitude 6.7 earthquake in 1944. Therefore, a similar quake in the future would not be surprising. Thus, we think the seismicity around the Edremit fault should be closely monitored."

Seismic swarms generally occur in geothermal areas where faults are lubricated by hot water, making them easier to slip, they explained.

"This area is one of the most active geothermal regions in Turkey, with some water temperatures reaching 174 ŗC (345 ŗF). Water boils at 100 ŗC (212 ŗF) at sea level but the high pressure environment underground prevents evaporation. Most seismic swarms end without triggering a large earthquake."

Earthquake on the beach: Scientists think a 7.4 temblor could reach from L.A. to San Diego

The discovery of missing links between earthquake faults shows how a magnitude 7.4 earthquake could rupture in the same temblor underneath Los Angeles, Orange and San Diego counties, a new study finds.

Such an earthquake would be 30 times more powerful than the magnitude 6.4 earthquake that caused the 1933 Long Beach earthquake, which killed 120 people.

But to get to a 7.4, the earthquake would not only have to again rupture the Newport-Inglewood fault in Los Angeles and Orange counties. The temblor would also have to jolt the adjacent Rose Canyon fault system, which runs all the way through downtown San Diego and hasn’t ruptured since roughly 1650.

“These two fault zones are actually one continuous fault zone,” said Valerie Sahakian, the study’s lead author, who wrote it while working on her doctorate at Scripps Institution of Oceanography at UC San Diego. Sahakian is now a research geophysicist with the U.S. Geological Survey.

In the past, scientists reported gaps between the two fault systems of as much as 3 miles apart. But the latest study shows the gaps are actually less than 1¼ miles apart.

“That kind of characterizes it as one continuous fault zone, as opposed to two different, distinct fault systems,” Sahakian said, making it far easier for an earthquake to keep shaking land as it races down a longer fault, widening the seismic reach of the temblor.

There had already been consensus among scientists over the last three decades that the fault systems were actually one, said Caltech seismologist Egill Hauksson, who was not involved with this study. “We now have real evidence that this is the case,” Hauksson said.

The difficulty in proving it was caused by the location of the gap — under the Pacific Ocean between Newport Beach and La Jolla. Drawing a better map meant trying to figure out where the fault was underwater.

So Scripps researchers hopped aboard boats, and in the fall of 2013 spent more than 100 days at sea collecting data. They created an image of what the earth looks like under the seafloor to estimate where the fault lies.

To do so, they used a technique kind of similar to how submarines use sonar or bats use echoes to see.

From the ship, scientists towed a machine that generates acoustic waves that bounce off the seafloor and deeper underground layers and returns to the ship, giving the data the scientists need to produce a better map of where the faults actually are located. The researchers also used previously collected data to perfect their new map.

Zware aardbeving Botswana
Een zware aardbeving heeft zuidelijk Afrika door elkaar geschud. Het epicentrum van de beving met een kracht van 6,5 lag op twaalf kilometer diepte en in het dunbevolkte centrum van Botswana.

Dat meldt de Amerikaanse seismologische dienst. Volgens data van de aardbevingsmonitor van het Duitse Helmholtzcentrum in Potsdam had de aardbeving zelfs een magnitude van 6,8.

De schok was ook voelbaar in de Zuid-Afrikaanse handelsmetropool Johannesburg en volgens media ook tot in Zimbabwe. Er is voorlopig geen nieuws over mogelijke schade of slachtoffers.

Botswana quake may have caused Durban tremor
Monday’s earthquake is reportedly the largest earthquake on record to have struck Botswana.

THE tremor felt in Durban and other parts of South Africa this evening may have been caused by an earthquake in Botswana.

A registered earthquake occurred in Botswana of 6.5 on the Richter Scale, according to earthquaketrack.com.

Several people took to social media, and reported feeling the tremor in Durban and surrounding areas, Johannesburg and Pretoria.

There has been no reports of any possible damage or casualties at the moment. Monday’s earthquake is reportedly the largest earthquake on record to have struck Botswana.

Here are more reactions from Twitter users over the tremor with some taking a light-hearted approach while others linking the tremor to South Africa’s political troubles.

Earthquake swarm registered near coast of Valparaiso, Chili

A series of moderate to strong earthquakes were registered near the coast of Valparaiso, Chile on April 22 and 23, 2017. EMSC is reporting at least 25 earthquakes since 22:46 UTC on Saturday, April 22, 2017, with the strongest registered as M6.0 at a depth 20 km (12.4 miles). USGS is reporting this one as M5.9 at a depth of 9.8 km (5.6 miles).

The quakes are occurring some 30 km (18.6 miles) west of Valparaiso (population 283 000) and 130 km (80.7 miles) west of capital Santiago (population 4 838 00) at depths between 10 and 30 km (6.2 - 18.6 miles). There are about 1 337 405 people living within 100 km (62 miles).

ONEMI director, Ricardo Toro, said seven earthquakes were felt by population between the regions of Coquimbo and O'Higgins. The maximum perceived intensity was VI on Mercalli scale in the communes of Valparaķso, Puchuncavķ, Casablanca, San Antonio and Villa Alemana, in the Valparaķso Region and in the commune of Tiltil, in the Metropolitan Region.

"According to information provided by the National Seismological Center, the strongest earthquake was 6.0 on the Richter scale, whose epicenter was 48 km (30 miles) west of Valparaiso," Toro said and added that tsunami from this one was not expected. "There were no reports of injuries or damage."

"We call on the population to remain calm, inform themselves through official channels and prioritize text messages or social networks to communicate, in addition to having their emergency kit ready in case of a major emergency," he said.

Ross Stein and Volkan Sevilgen of Temblor said the quakes are occurring on or near the megathrust surface 30 km (18 miles) offshore the major port city of Valparaiso.

"Sustained sequences of moderate shocks are rare; most instead begin with the largest shock, termed the ‘mainshock,’ followed by ‘aftershocks’ that become less frequent with time, and are only rarely larger than the mainshock. So, in both respects - magnitude and frequency - this sequence looks different. Staccato seismic swarms like this one probably accompany slow slip on either the megathrust, or a thrust fault that splays off the megathrust. The depth and location of the sequence, as well as the ‘focal mechanism’ of the largest shock, suggest that the sequence is occurring on, or more likely above, the megathrust surface, where the Nazca Plate is descending beneath the South American Plate," they explained.

Guatemala's earthquake triggers landslides

GUATEMALA CITY - A magnitude 6.9 earthquake in western Guatemala near the border with Mexico caused moderate damage to homes, triggered some landslides across highways and injured at least one person early Wednesday, officials said.

The U.S. Geological Survey reported the tremor was centered 5 miles southwest of Tajumulco, Guatemala about 69 miles below the surface.

Guatemala's emergency coordination agency said the quake struck at 1:29 a.m. local time in the department of San Marcos west of the capital near the Mexican border, but was felt throughout the country.

The country's National Civil Police said one person was injured in San Sebastian Retalhuelu in southern Guatemala when part of a church collapsed. Julio Sanchez of the volunteer firefighters said the man, who was passing by the church when the earthquake struck, was receiving care.

Authorities reported several departments, or states, without electricity.

Across the border in Chiapas, Mexico, Gov. Manuel Velasco said via Twitter that there were reports of cracked walls and shattered windows in Huixtla, but so far no injuries. The state's Civil Protection authorities said the quake was felt throughout the state.
