A slow-moving river of millipedes crawling on the ground in unison was recently spotted in a mountainous area of Taiwan and the video of it is enough to make your skin crawl.

On April 27th, tourists visiting Hsüeh-Pa National Park in central Taiwan witnessed an unusual phenomenon that local guides have never seen before. While accompanying a group of seven tourists through an area west of Dalu Forest Road, Yang Xiaozhong, a tour guide with an experience of 11 years, noticed that the path he knew seemed to be covered with fallen leaves. At first, he thought the brown leaves must have been brought to the ground by heavy rains but then he realized that the foliage was actually moving. On closer inspection, the leaves turned out to be millipedes, thousands of them moving in the same direction, like a living river.

China’s Qiantag River is famous for a unique natural phenomenon, a wavy pattern tide that was only observed for the first time in 2021 and has come to be known as fish scale tide.

The Qiantang River’s estuary in Zhejiang Province has long been famous for having the strongest tidal bores in the world. At times, they can get as tall as nine meters, which means the area regularly sees trains of large waves moving upstream against the normal current. However, in 2021, during a scientific expedition, researchers discovered another intriguing natural phenomenon unique to this estuary. When certain conditions are met, the tide comes in spiraling waves that look like fish scales on the water’s surface. The phenomenon hs become known as ‘fish scale tide’.

Lajamanu, a remote community in the Australian outback, near the Tanami Desert, recently experienced its fourth rain of fish in the last 50 years.

They say lightning never strikes in the same place twice, but apparently the same cannot be said about raining fish. The arid town of Lajamanu, in the Northern Territory outback, sees very little normal rain, but somehow it has experienced no less than four ‘fish rains’ in the last half-century – once in 1974, another in 2004, again in 2010, and last Sunday. Although the nearest fish-containing body of water is many miles away, locals swear that live fish started falling from the sky during a powerful storm, and they even have photos to back up those claims.

Kagami Numa is a mythical Japanese lake that turns into a giant eye every spring, during the thawing process, hence its nickname, Dragon’s Eye Lake.

Located near the summit of Mount Hachimantai in north-eastern Japan, in the middle of a dense forest, Kagami Numa doesn’t look much different than the many other volcanic lakes in the area, most of the year. But for about a week – ate May to early June – it turns into a giant blue eye that inspired its intriguing nickname, Dragon’s Eye Lake. The unique appearance of the circular lake during this one week has inspired a legend of two dragons in love that chose this body of water as their meeting spot.

For at lest 300 years, hikers in California’s Santa Lucia Mountains have been reporting sightings of shadowy, mysterious silhouettes popularly known as “dark watchers”.

The first reports of giant figures ominously perched on mountaintops date back to the 1700s, when the Spanish first came to California. They were actually the first to dub these mysterious strangers “los Vigilantes Oscuros” (the dark watchers), but the first Anglo-American settlers that came after them reported similar sightings, and the figures eventually became part of the local folklore. The strange thing is that dark watchers still show themselves to hikers in the Santa Lucia Mountains, and some have even been captured on camera.

Thousands of people are living fear of being swallowed up by the Earth after hundreds of sinkholes appear in an area that was shaken by strong earthquake just over two months ago.

On December 29, 2020, Croatia recorded its strongest earthquake ever. Measured at 6.4 points on the Richter magnitude scale, the quake directly affected 116,000 people, mainly in the cities of Petrinja, Sisak, and Glina, and the rural areas around them. Over 35,000 homes and 4,550 businesses were damaged by the strong tremor and its many aftershocks, and five fatalities attributed to the destructive natural phenomenon were reported. Now, over two months since the earthquake, people in the affected area are even more worried about the sink holes that keep appearing.

In winter, Siberia’s Lake Baikal becomes the scene of a rare natural phenomenon known as “Baikal Zen”. Large stones balance on thin ice “legs” above the surface of the lake, making it seem like they are floating in the air.

Lake Baikal is a fascinating body of water. It’s so large it can easily be mistaken for a sea, it is also the deepest and oldest lake on Earth, as well as the largest freshwater lake by volume. But these are only the most well-known facts about Lake Baikal. There are other more mysterious things going on there, some of which give the place a mystical, almost magical aura. Take the phenomenon known as Baikal Zen, for example – large, Zen-like pebbles balancing precariously on a thin ice pillar, above the frozen surface of the lake. Scientists have been studying this rare phenomenon for years, and we still don’t have a unanimously accepted explanation for it.

Ever since the 1960s, seismologists on multiple continents have detected a mysterious pulse generated like clockwork, every 26 seconds. But in the last 60 years no one has been able to figure out what this sound actually is.

The “heartbeat of the Earth” was first documented in 1962, by John Oliver, a researcher at the Lamont-Doherty Geological Observatory, Columbia University. He figured out that it was coming from somewhere in the southern or equatorial Atlantic Ocean, and that it was more intense during the Northern Hemisphere’s summer months. Then, in 1980, Gary Holcomb, a geologist with the U.S. Geological Survey, also discovered the mysterious pulse, noting that it was stronger during storms. But for some reason, the two researchers’ discoveries remained virtually unknown for over two decades, until a graduate student at the University of Colorado, Boulder, once again detected the “heartbeat” and decided to look into it.

Once every 7 to 10 years, Nevada’s Lake Pyramid experiences an algae boom so significant that its color changes from dark blue to a vibrant turquoise. This phenomenon is known as “whiting”.

Located in a remote desert area of the Pyramid Lake Paiute Tribes’ Reservation, about 40 miles northeast of Reno, Lake Pyramid is famous for the whiting events that occur there every decade or so. Over the course of a few weeks, the water turns light blue, turquoise, and, in rare cases, even white. This spontaneous precipitation of calcium carbonate is well documented, but not very well understood. All scientists know is that contributing factors include high water temperatures, algae bloom and increased calcium concentrations. Interestingly, whiting events are not dangerous to the aquatic life. However the same cannot be said for land life, including humans…

A temporary waterfall in Yosemite National Park has become a popular tourist attraction in the mouth of February, because under the right conditions sunlight makes the water flowing down the rock face look like fire, hence its nickname, Yosemite Firefall.

Every year, from December to April, water from melting mountain snow flows toward the eastern edge of El Capitan, forming the temporary Horsetail Falls. The waterfall itself is quite a sight to behold, but it becomes truly breathtaking for a few days (7 -10) in February, when, under the right conditions, it turns into a firefall, with the water looking like flowing lava and swirling flames. The Yosemite Firefall is considered one of the most amazing spectacles one can behold in Yosemite National Park.

A floating tree stump known as the “Old Man of the Lake” has been bobbing in the blue water of Oregon’s Crater Lake for at least 120 years, baffling scientists with its upright orientation and allegedly even controlling the local weather.

The first account of the Old Man of the Lake dates back to 1896, when geologist and explorer Joseph Diller described a splintered and bleached white log floating vertically in Crater Lake. Five years later, Diller observed that the unusual log had moved 400 meters from the location it had originally been spotted at. Further research would show that the Old Man of the Lake is able to move more than four miles in just one day, despite lacking any apparent means of propulsion. How it’s able to do that is still a mystery, but it’s only one of many.

Shocking photos of a popular beach in the Mexican state of Oaxaca sinking into the Ocean have been doing the rounds on social media, leaving people scratching their heads in disbelief. It turns out the sinking is being caused by a phenomenon known as “mar de fondo”, or “swell”.

Swells rarely occur at popular seaside destination, which only makes the repeated sinking of the beach at Puerto Escondito, in Oaxaca, that much more peculiar. Swells, also known as surface gravity waves, are created by storms thousands of miles away from the beaches on which they break, and are not influenced by local winds. They cause a rise in sea level, but are different than high tide, eating away at the sand they it, and causing large stretches of beach to simply sink into the ocean. This is what happened at Puerto Escondito last week, but the really strange part is that the exact same thing occurred in the same place, in May of last year.

An Australian couple sailing their catamaran towards Fiji, in the Pacific Ocean, encountered a 150-square-kilometer pumice raft drifting towards Australia.

Believed to have been produced by an underwater volcanic eruption near the island of Tonga, the pumice raft is over 20,000 football fields in size and several inches thick. Its existence was first reported on August 16, by a couple who encountered it while sailing towards Fiji. The vast expanse of floating volcanic rock slowed their catamaran to a speed of one knot and completely covered the ocean surface as far as the eye could see.

The people of Siberia’s Verkhoyansk district got a feeling of deja vu last Friday when they woke up to total darkness at an hour when the sun should have been high in the sky. A similar phenomenon occurred in the region just over a year ago.

This time of year, dawn breaks at around 4 am in Verkhoyansk, but photos taken by locals at around 8 in the morning show no sign of the sun, as entire settlements are bathed in almost complete darkness with a bizarre yellow tinge to it. Luckily, locals were used to such unusual phenomena, as just last year, in July, Verkhoyansk and other Yakutian regions experienced another pitch black morning. In fact some people took to social media to ask if this is becoming some sort of weird tradition.

The small village of Dinoša, in Montenegro, is home to an old mulberry tree that turns into a water fountain every time it rains heavily.

As we all know, water doesn’t normally gush out of living trees, but at least in this case the phenomenon has a perfectly reasonable explanation. You see, the meadow that the mulberry tree grows in has many underground springs which flood during heavy rainfalls, and the additional pressure pumps the water up through the hollow trunk of the tree and out through a hole a few feet above the ground.
