Saudi Arabia’s blue holes: Geological wonders

Saudi Arabia establishes the Blue Holes Protected Area to preserve unique marine sites

These blue holes form vibrant ecological systems, sheltering turtles, fish, marine mammals and a wide range of invertebrates.

 Saudi Arabia’s Blue Holes — a chain of deep-sea sinkholes stretching along the southwestern coastline between Makkah and Jazan — are quickly gaining recognition as one of the Kingdom’s most remarkable natural features. These striking circular depressions, visible as dark blue pools against the Red Sea’s lighter turquoise waters, offer a rare glimpse into geological processes that have unfolded over millions of years.

Formed through rock fissures, limestone dissolution, tectonic shifts, and the gradual collapse of ancient underwater cave systems, the blue holes are considered invaluable geological archives. Their steep vertical walls and layered sediments allow scientists to study past climate patterns, sea-level changes, and long-term developments within the Red Sea basin. For researchers, each sinkhole is a natural time capsule preserving evidence of marine evolution.

What are blue holes?

Blue holes are deep, vertical underwater sinkholes found in carbonate rock formations around the world, including well-known examples in Belize, China, and even a modest one in the UAE. They form unique ecosystems rich in biodiversity and serve as havens for sea turtles, reef fish, marine mammals, invertebrates, and specialised organisms that thrive in low-light, low-oxygen environments. Their depth and isolation often result in distinct water chemistry, creating conditions that are unlike those of the surrounding seas.

Recognising their ecological and scientific importance, Saudi Arabia designated the Blue Holes Protected Area, now one of the Kingdom’s largest marine conservation zones. Spanning more than 16,500 square kilometres and including over 20 islands, the protected area shelters coral reefs, migratory species, and sensitive coastal habitats vital to Red Sea biodiversity.

This conservation effort aligns with Saudi Arabia’s Vision 2030 goals, which prioritise expanding protected natural areas, enhancing sustainability, and fostering responsible eco-tourism. By safeguarding these underwater formations, the Kingdom aims to support scientific research while opening opportunities for nature-based tourism and community engagement.

Silent, ancient, and visually captivating, Saudi Arabia’s blue holes remain among the Red Sea’s most incredible natural wonders — still holding secrets waiting to be uncovered.

Is February 2026 really a once-in -283-years MiracleIn?

A viral message is making the rounds again ahead of February 2026, claiming the month will be a once-in-a-lifetime calendar event — one that ‘only happens once in 823 years.’

The text is usually shared in group chats and social media captions with an urgent tone: February 2026 will have 4 Sundays, 4 Mondays, 4 Tuesdays… and so on, ending with the phrase ‘This is called MiracleIn.’ Some versions even add a superstition-style instruction to forward the message for ‘miracles.’

But fact-checkers and calendar experts say the claim is misleading, and the maths behind it is straightforward.

Why February 2026 isn’t rare

February 2026 has 28 days because 2026 is not a leap year. And a 28-day month is exactly four weeks (28 ÷ 7 = 4).

That means every weekday appears exactly four times in any standard February — which is the normal pattern, not a rare one.

AFP Fact Check has debunked nearly identical claims about February, explaining that in all non-leap years, February naturally contains four of each weekday.

Africa Check also reached the same conclusion, noting that the ‘823 years’ figure is recycled misinformation that resurfaces regularly, often rewritten with a new year.

Timeanddate.com, which has repeatedly tracked these calendar rumours, lists the February ‘MiracleIn’ message as a false viral claim and explains that the weekday pattern is simply what happens when February has 28 days.

What about the ‘MiracleIn’ part?

The term ‘MiracleIn’ has no recognised scientific or calendar meaning. One widely shared version also suggests February 2026 will include a 25-hour day, which fact-checkers say is not a global phenomenon.

In short: February 2026 is not a rare ‘miracle month.’ It’s a standard February — and the viral message is another recycled calendar myth dressed up as a once-in-centuries event.

465m-year-old horseshoe crab fossils found in AlUla

The Royal Commission for AlUla has announced the documentation and publication of a rare fossil discovery of horseshoe crabs dating back approximately 465 million years, following a peer-reviewed scientific study published in the geology journal Gondwana Research.

The discovery, published for the first time at a global level, strengthens AlUla’s standing as an international centre for geological and scientific research related to Earth’s history and biodiversity. The fossils were uncovered in the Gharameel Nature Reserve in AlUla.

Dating to the Middle Ordovician period, roughly between 485 and 444 million years ago, the fossils are among the oldest known horseshoe crab specimens worldwide. They are distinguished by their unusually large size compared with other species from the same era. All specimens were found preserved upside down, a mode of fossilisation not previously recorded, alongside trace fossils indicating attempts by the organisms to right themselves

Geological layer analysis suggests the area was subject to repeated strong seasonal storms, indicating that these ancient creatures gathered in shallow coastal environments affected by such events, which contributed to their preservation within sedimentary deposits.

The findings provide a clearer picture of AlUla’s ancient environment as a coastal region and add a new scientific dimension to understanding its geological and environmental history. The commission said the analysis demonstrates its ability to generate accurate data that supports scientific research and innovation.

The discovery also represents a previously undocumented species that has yet to be formally classified. Research has been conducted in two phases in collaboration with a team led by Dr Russell Bicknell of Flinders University. The second phase, scheduled for the first half of 2026, will involve the collection of additional samples and further study prior to official classification. The fossil samples have been preserved within the commission’s museum collections to support future research and public engagement.

The commission said the discovery reflects its commitment to advancing scientific research and reinforcing AlUla’s position as a global destination for geological discovery, international collaboration and education linked to natural heritage, in line with the objectives of Saudi Vision 2030.
