A warped section of the B4069 near Lyneham in Wiltshire has left residents mystified as to exactly what underground processes could have caused the earthquake-like damage
A ripped up road could cost millions to repair after mysterious underground movements left it so warped it looks like it had been hit by an earthquake.

A section of the B4069 near Lyneham in Wiltshire has been so badly damaged the tarmac has completely snapped or is at a 45 degree angle.

Wiltshire Council say the road has been closed since February 17 - but some drivers are still trying to use it according to police.

The earthquake-like damage has been caused by unexplained underground movements which will now be investigated.

Famous Kashmir trout stream vanishes into sinkhole

River goes underground in Kokernag Anantnag
River goes underground in Kokernag, Anantnag
A famous Kashmir trout stream has vanished into a sinkhole spreading fear in the south Kashmir Kokernag area. The famous Brengi stream in the Kokernag area of Anantnag district has been draining into a sinkhole leaving the rest of the stream dry during the last two days.

Brengi stream is one of the most famous trout angling streams which is sought after by anglers for its brown trout species. Two days back, a huge sinkhole developed in the stream which has been draining all the run of the stream water into it.

This has left the downstream portion dry killing trout fish in large numbers. District authorities said around 50 cusecs of water was draining into the sinkhole at the moment. It must be recalled that in winter all the streams and rivers in the Valley have minimum discharge. Authorities have imposed section 144 CrPc in the area to prevent people going closer to the sinkhole since scores of locals have been visiting the place to see the disturbing sight.

Hidden magnitude-8.2 earthquake source of mysterious 2021 global tsunami

Hidden Earthquake

Scientists have uncovered the source of a mysterious 2021 tsunami that sent waves around the globe.

In August 2021, a magnitude 7.5 earthquake hit near the South Sandwich Islands, creating a tsunami that rippled around the globe. The epicenter was 47 kilometers below the Earth's surface — too deep to initiate a tsunami — and the rupture was nearly 400 kilometers long, which should have generated a much larger earthquake.

Seismologists were puzzled and sought to understand what really happened that day in the remote South Atlantic.

A new study revealed the quake wasn't a single event, but five, a series of sub-quakes spread out over several minutes. The third sub-quake was a shallower, slower magnitude 8.2 quake that hit just 15 kilometers below the surface. That unusual, "hidden" earthquake was likely the trigger of the worldwide tsunami.

The study was published in the AGU journal Geophysical Research Letters, which publishes short-format, high-impact papers with implications that span the Earth and space sciences.

Because the South Sandwich Islands earthquake was complex, with multiple sub-quakes, its seismic signal was difficult to interpret, according to lead study author Zhe Jia, a seismologist at the California Institute of Technology. The magnitude 8.2 quake was hidden within the tangle of seismic waves, which interfered with each other over the course of the event. The hidden quake's signal wasn't clear until Jia filtered the waves using a much longer period, up to 500 seconds. Only then did the 200-second-long quake, which Jia said accounted for over 70% of the energy released during the earthquake, become clear.

"The third event is special because it was huge, and it was silent," Jia said. "In the data we normally look at [for earthquake monitoring], it was almost invisible."

A Kowloon Motor Bus Company double-decker plunged into a sinkhole that opened up at a depot in Tseung Kwan O early on Thursday morning.

The rear of the bus plunged into the five-meter-deep hole, while the front was lifted above the ground three to four meters high. Another bus adjacent to the double-decker also tilted.

KMB staff reported the incident at around 4.30am today and no one was injured in the incident.

The bus company said the sinkhole at the depot measures six meters long, eight meters broad and five meters deep.

Crews in Birmingport are investigating after a dump truck fell inside of a sinkhole.

Officials with the Birmingport Fire Department say a man was eating lunch in the truck in the parking lot of a grocery store, when the ground gave way. The back end of the truck fell about six to eight feet. Officials say it looks like a culvert under the ground dropped away. Officials say there was some diesel leakage, but crews stopped most of it from getting into the creek near the road. No injuries have been reported.

The Jefferson County EMA and the Alabama Department of Environmental Management are investigating.

Is the Eye of the Sahara 'the Lost City of Atlantis'?


Comment: Short answer; no it is not. It's an impact site (caused by an overhead cometary explosion)...


Atlantis and Richat Structure

Could a curious geological formation in the Mauritanian part of the Sahara desert anything to do with the lost city of Atlantis?

If you type the word "Atlantis" into Google, around 120 million results will pop up. Obviously, Plato's legend of Atlantis has long occupied many people, from scientists to mysticists, with many candidates being cited as the possible location of this lost and sunken civilization. But did such a city ever exist at all? And if yes, where could the ruins be?

The only mention of Atlantis by name in historical texts is in Plato's Dialogues (written around 360 B.C.), which gives dozens of precise details about what Atlantis looked like, and where it may have been located in relation to other landmarks in the ancient world. It was this level of detail that has set many people off thinking that Atlantis actually existed.

One of the best clues that Plato gives about Atlantis is that there was a series of concentric circles around the city, black and red stone, and of course it was a seafaring society:
Poseidon carved the mountain where his love dwelt into a palace and enclosed it with three circular moats of increasing width, varying from one to three stadia and separated by rings of land proportional in size. The Atlanteans then built bridges northward from the mountain, making a route to the rest of the island. They dug a great canal to the sea, and alongside the bridges carved tunnels into the rings of rock so that ships could pass into the city around the mountain; they carved docks from the rock walls of the moats. Every passage to the city was guarded by gates and towers, and a wall surrounded each ring of the city. The walls were constructed of red, white, and black rock, quarried from the moats, and were covered with brass, tin, and the precious metal orichalcum, respectively.
So, according to Plato, Atlantis looked something like this:

The outlook is grim for Konya Plain, a massive stretch of land in the eponymous province viewed as Turkey's breadbasket. The number of sinkholes, which was only 600 in January 2021, has now reached 2,000, experts say, amid concerns over more formations.

Sinkholes, a result of diminishing groundwater levels, is now closer to residential areas and agricultural fields, professor Fetullah Arık, an expert who heads a sinkhole research center at Konya Technical University, says.

Most emerge overnight and no casualties or damage have been reported so far, but Arık warns the risk is becoming higher. The center he leads cooperates with the Disaster and Emergency Management Presidency (AFAD) for measures against sinkholes, which vary in size but are large enough to pose a risk.

Rapid & significant land subsidence in Cartagena, Colombia, revealed by satellite data

A rapid rate of land subsidence could make sea level rise estimates worse for one of Colombia's tourist destinations. This could serve as a warning sign to other coastal cities.

FIU geophysics professor Shimon Wdowinski, Juan Restrepo-Ángel from EAFIT University in Colombia and a team of international scientists found Cartagena on the Caribbean Sea is experiencing serious subsidence with some areas subsiding at rates up to almost half an inch a year. Combined with the effects of rising seas due to the climate crisis, increased coastal flooding and erosion, this degree of subsidence could make matters much worse.

"So far, coastal flooding has occurred mainly due to storm surge, but with rising sea level and coastal subsidence, we expect an increasing frequency of flood events," Wdowinski said. "It is clear subsidence poses a major threat to Cartagena's preservation."


Comment: There's no evidence that, on the whole, sea levels are rising: Kiribati and China to develop farm land in Fiji, land had been predicted to 'disappear under a rising ocean'


Comment: Notably, that's not the only location where changes like this have been noted: And it's even more interesting when one takes into account the uptick in sinkholes, seismic, and volcanic activity in recent years: See also: Expanding Earth?
