Scientists Find a 'Yellow Brick Road' in a Never-Before-Seen Spot of The Pacific Ocean
by Carly Cassella
December 21, 2022

Introduction:
(Science Alert) An expedition to a deep-sea ridge, just north of the Hawaiian Islands, has revealed an ancient dried-out lake bed paved with what looks like a yellow brick road.

The eerie scene was chanced upon by the exploration vessel Nautilus earlier this year, while surveying the Liliʻuokalani ridge within Papahānaumokuākea Marine National Monument (PMNM).

PMNM is one of the largest marine conservation areas in the world, larger than all the national parks in the United States combined, and we've only explored about 3 percent of its seafloor.

Researchers at the Ocean Exploration Trust are pushing the frontiers of this wilderness, which lies more than 3,000 meters below the waves, and the best part is, anyone can watch the exploration.

A highlight reel of the expedition's footage published on YouTube in April 2022 captures the moment researchers operating the deep-sea vehicle stumbled upon the road to Oz.

The actual moment of discovery is at about the 1:40 point:

One of my younger Facebook friends works in the field of public safety (911 operator). She has moved around a bit so I kind of lost track of where she was living. She travels a lot, so I also see photos from all over California showing up on her Facebook page. Turns out she was apparently relatively close to the epicenter at the time of its occurrence. She shared photos of the mess in her house from toppled furniture and things that fell off of her shelves when she reached her home. Also of interest was a feature through the Facebook system wherein she was "marked as safe" through her post. It included a map showing the epicenter of the quake. An interesting way of briefly notifying concerned friends of your safety as well as providing more information concerning the quake to people from far away who may have read a headline or two.

The quake was too far to the North for me to feel it. We sometimes hear of smaller magnitude quakes that have hit or area that we didn't even feel because of the low level of energy. We would have definitely felt a 6.4 had it been closer.

BREAKING:

Major 7.8-7.9M earthquake reported in south central Turkey near the Syrian border.

Models suggesting anywhere between 100-10000 deaths likely based on location and projected shaking.



Lots of videos of collapsed buildings coming in.

Turkey getting rocked by an earthquake swarm along the East Anatolian Fault.



Damage being reported now across the country as well as Syria and Lebanon.

Shaking felt in Israel, Iraq, and even in Greece.

^^^Thanks for the heads up. For details:

Very strong 7.8 quake hits near Gaziantep, Turkey
February 6, 2023 (Updated 29 Minutes Ago).

Introduction:
(Volcano Discovery) An earthquake of magnitude 7.8 occurred only 18 minutes ago 37 km northwest of Gaziantep, Turkey, the United States Geological Survey reported.

The quake hit at a shallow depth of 24.1 km beneath the epicenter near Gaziantep, Turkey, early morning on Monday, February 6th, 2023, at 4:17 am local time. The exact magnitude, epicenter, and depth of the quake might be revised within the next few hours or minutes as seismologists review data and refine their calculations, or as other agencies issue their report.

A second report was later issued by the German Research Centre for Geosciences (GFZ), which listed it as a magnitude 7.4 earthquake. Other agencies reporting the same quake include France's Réseau National de Surveillance Sismique (RéNaSS) at magnitude 7.0, the citizen-seismograph network of RaspberryShake at magnitude 7.7, the citizen-seismograph network of RaspberryShake at magnitude 7.8, and the European-Mediterranean Seismological Centre (EMSC) at magnitude 7.6.

Generally quakes of this magnitude are recorded by more than one agency and the results can vary, with subsequent reports that come in after the first one often showing more accuracy.

If the preliminary data about magnitude and depth are correct, the quake was extremely dangerous. It has the potential to cause catastrophic impacts on people and infrastructure, probably involving severe and wide-spread damage, especially in areas near the epicenter.

Some video coming in from Syria.



Many of the Syrian cities have been damaged by years of war and their buildings were particularly vulnerable.

Both Hama and Aleppo were within the predicted strong shaking from this quake as well as Gazantiep in Turkey which was the closest city to the epicenter and has a population of more than a million people.

If the preliminary 7.8/7.9 is confirmed this would be the strongest confirmed earthquake in Turkish history.

The only earthquakes that rival it would be:

https://en.wikipedia.org/wiki/1939_Erzincan_earthquake

The second would be more comparable to today's and that earthquake killed over 30000 people! This one might be just as bad...

Update: Aleppo

Unlike the earthquakes the Middle East has recently experienced the weather is looking like it will be below freezing starting on Tuesday each night.

If they don't get people out, those who are trapped could freeze...

This is almost certainly going to be the worst earthquake in the region since 1999's Izmir...

Update: Turkish city of Adana 1.7m people...

I expect thousands of deaths. We will see but history tells me that is to be expected in these kinds of events.
