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 Valparaíso, Puchuncaví, Casablanca, San Antonio and Villa Alemana, in the Valparaíso 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.
