Strong magnitude 6.1 earthquake shakes Nicaragua

mapped
A strong earthquake shook Nicaragua Thursday morning, sending people fleeing into the streets, but there were no initial reports of damage.

The U.S. Geological Survey said the earthquake had a preliminary magnitude of 6.1 — down from an initial calculation of 6.2. It was centered on the country's Pacific coast about 36 miles (59 kilometers) south of Corinto. The earthquake was at a depth of 17 miles (27.5 kilometers).

It was felt strongly in Managua, the capital, where residents milled about outside their homes and workers cleared government buildings. Travelers at the capital's international airport were evacuated from the terminal.

The earthquake, which hit at 10:25 a.m. (11:25 a.m. EST; 1625 GMT), was also felt to the north in El Salvador.

Vice President and first lady Rosario Murillo told government media that despite the earthquake's strength there had been no immediate reports of victims nor damage.

More shaking in Midlands with another earthquake. It was among the strongest to hit

Earthquakes and aftershocks continue to shake the Columbia area as tremors from a fifth quake were confirmed early Wednesday morning.

Dozens of people have reported feeling the 2.4-magnitude earthquake that hit near Elgin at 4:12 a.m., according to the U.S. Geological Survey. The quake recorded at a depth of 6.0 kilometers is the fifth to hit the Midlands in a three-day span.

The latest earthquake was more powerful than the last two confirmed in Kershaw County Monday night, and the sixth most powerful of the 28 earthquakes confirmed in the Palmetto State in 2021, according to the South Carolina Department of Natural Resources.

This picture taken on December 21, 2021 shows white gaseous clouds rising from the Hunga Ha'apai eruption seen from the Patangata coastline near Tongan capital Nuku'alofa.
The Hunga Tonga Hunga Ha'apai volcano continues to erupt intermittently, and ash has been detected in all directions up to 30km away.

The head of Tonga Geological Services, Taaniela Kula, said that the ash cloud had risen to heights of 12km and the direction of ash had varied with the wind conditions.

"On Tuesday, ash was drifting east but shifted directions last night to north east and has continued to drift in a northerly direction today," he said.

Overall, the amount of ash, steam and gas being spewed from the volcano has reduced, in comparison to last week, Kula said.

He noted that the volcano was about 60km away from uninhabited areas, and that no earthquakes had been detected on their seismometers.

Indonesia: Islands rocked by massive 7.3 magnitude earthquake - locals on high alert

quake
The extremely strong quake hit Kepulauan Barat Daya, some 113km northeast of Lospalos, Municipio de Lautem, Timor-Leste. It struck at 3.25am local time at an immediate and considerable depth of 200km, according to the European-Mediterranean Seismological Centre (EMSC). That has since been downgraded slightly to a depth of 167km by the United States Geological Survey (USGS).

A tsunami warning has not been issued for the surrounding islands.

The impact of the earthquake was felt as far as 600km away in Darwin, the capital of Australia's Northern Territory.

Around 1,700 of its residents have reported feeling tremors early on Thursday, according to Geoscience.

The Volcano Discovery website said, based on preliminary seismic data, the earthquake was likely felt by "many" people in the area of the epicentre.

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)...

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:
