Incredible Footage From Inside the Eye of a Tornado

Tornado

On May 28, 2008, a funnel touched down in the farm fields of central Iowa. Within minutes it grew into a massive, mile-wide monster. Damage surveys would later determine that the tornado was an EF5, the most powerful type of tornado, capable of reducing rows of well-constructed homes down to bare foundations. It roared through rural farmland for several miles before then heading due east towards the small town of Parkersburg.

Surveillance cameras were rolling at the First State Bank building in Parkersburg, a little before 5pm that Sunday. One exterior camera, used to record an outdoor ATM, showed calm weather only 20 seconds before the town was obliterated. What the camera captured next is nothing short of a nightmare.

The First State Bank was perhaps the sturdiest structure in the path of the tornado. Built with heavy brick and stone masonry, the building was one of the only things left standing in the Southern part of town. But the winds were able to penetrate through the bank's windows and unreinforced walls, and footage from inside shows how quickly it became filled with deadly debris.

The First State Bank's tornado footage is part of a growing collection of surveillance videos that are giving us a first-hand look at the fury of a tornado.

Only three weeks before the Parkersburg event, surveillance camera's at an equipment company outside of Leighton, Alabama captured an EF2 tornado as it tore through a parking lot. The tornado touched down only seconds before it came into frame and contained an embedded suction spot powerful enough to toss several cars and trucks into the air.

Back in 1998, a deadly outbreak of tornadoes occurred in central Florida. A newly opened Winn Dixie supermarket still had a few people inside when one of the early morning tornadoes roared over the store. Surveillance footage shows the powerful winds blowing through the plate glass doors at the entrance of the store and filling the air with debris and candy.

More recently, on August 19, 2009, a small tornado touched down near downtown Minneapolis. Although it was weak, the tornado still packed winds strong enough to blow out hundreds of windows and damage the roofs of several dozen homes and businesses in the area.

Incredible tornado footage is becoming more and more prevalent as the use of video and surveillance cameras continues to increase. And as unlucky as the businesses were that captured these images, their footage gives us a unique and fascinating view that few people have seen and actually lived through.

Breathtaking Images of Frozen Waves

All images by Tony Travouillon were taken at the Antarctic base of Dumont D’Urville.

Though spring is going by fast, there are certain parts of the world that are covered by snow and ice even during the summer months. In fact, it is so cold that even waves seem to freeze in midair. But can waves freeze over as word on the Intertubes would have us believe? Sorry folks, if you’ve thought yes then you’ve fallen prey to an urban myth.

Frozen waves are actually formed over time in a process called glaciation. Yup, they are nothing but beautifully shaped glaciers found all over the world - the polar regions of course but also in the mountain ranges of every continent, even in the tropics. According to Wikipedia, a glacier is a “perennial mass of ice which moves over land.” On its journey, the ice gets compacted and uplifted in the process and, as seen in the images below, often gets shaped beautifully through constant exposure to the elements.

And, quite contrary to intuition, the formations in the images shown here were formed through melting, not freezing. The downward parts on the ice that look like breaking waves are actually icicles, and the different colours are the result of how quickly the ice has frozen before melting: Rapidly frozen ice will look opaque while transparent ice is the result of ice frozen over time. Melting then produces the smooth, polished surfaces that remind us of waves.

Like a wave but…

Don’t be fooled, this is a real wave:

Did you know that glaciers are the largest reservoirs of fresh water on Earth? They form the second largest reservoir of total water on Earth, second only to the oceans. Amazing, isn’t it? So what we call frozen waves or waves of ice are not only beautiful to look at but also important water resources crucial for human survival.

Rare Photographs of Now Extinct Beasts

Written By: Karl Fabricius - who has written 164 posts on Environmental Graffiti.

From panthers and pandas to rhinos and tigers, dwindling animal numbers speak of the need to step up conservation efforts – if it’s not already too late. As a kind of wake-up call, we decided to take a look at seven extinct megafauna species captured on camera. With modern photography having only been invented in the 1820s, these snapshots are visible testament to just how recently the creatures shown were wiped out – and a jarring reminder of the precarious situation for many species still left on the planet.

1. The Tarpan

The last Tarpan died on a Ukrainian game preserve at Askania Nova in 1876. A prehistoric type of wild horse that once roamed from Southern France and Spain eastwards to central Russia, the Tarpan died out in the wild in the late 1800s. Reasons for its extinction include the destruction of its forest and steppe habitat to make room for people; hunting by farmers averse to their crops being eaten and mares stolen; and absorption into a growing domestic horse population. There have been various attempts to recreate the Tarpan through re-breeding, resulting in horses that do at least resemble their extinct forebears.

2. The Quagga

Another extinct equine beast – this time a subspecies of zebra – the last wild Quagga was probably shot in the late 1870s, while the last specimen in captivity died in 1883 at Artis Magistra Zoo in Amsterdam. Once abundant in southern Africa, the Quagga fell victim to ruthless hunting for its meat and hide, and because it was seen by settlers as a competitor to livestock like sheep. It was the coat of the Quagga that distinguished it best, with only the front part of its body showing the zebra’s vivid striped markings. As with the Tarpan, projects to breed back the Quagga have produced favourable results, visually at least.

3. The Javan Tiger

The Javan Tiger was a subspecies of tiger found only on the Indonesian island of Java, until it died out as recently as the 1980s. In the early 19th century, the Javan Tiger was common all over the island, but rapid human population increase led to the destruction of its forest habitat. The Javan Tiger was also mercilessly hunted, so that by the 1950s it is thought fewer than 25 remained in the wild. Following in the tracks of the Bali Tiger, which was wiped out in the 1930s, the fate of the Javan Tiger speaks for the precarious position of the tiger species as a whole. Sightings of the subspecies persist but hopes for its survival are fading.

4. The Caspian Tiger

Another tiger to vanish in the last century was the Caspian Tiger, the last confirmed reports of which date back to before the 1950s. Recent research suggests the Caspian Tiger was largely identical to the Siberian Tiger, but even if not a distinct subspecies, it yet had its own range and habitat. Found in the sparse forest and river basin corridors of Central and Western Asian, this big cat succumbed to intense hunting by the Russian army, who were told to exterminate it during a huge land reclamation programme in the early 1900s. Farmers followed, clearing forestland, and the loss of the Caspian Tiger’s primary prey, the boar, spelled its demise.

5. The Syrian Wild Ass

The last member of this species died at Schönbrunn Zoo, Vienna in 1928. Formerly occupying the mountains, deserts and steppes between Palestine and Iraq, the Syrian Wild Ass disappeared from the Syrian desert during the 18th century, not helped by war between Palestine and Syria. It was eradicated in Northern Arabia during the 19th century, and then became most seriously threatened with World War I, when its remaining habitat was overrun with fighting forces. The rest is history. This smallest of all recent members of the horse family stood just over 3 feet high at the shoulder and was generally light in colour.

6. The Bubal Hartebeest

The Bubal Hartebeest was a species of antelope that became extinct in 1923, when a captive female died in Jardin des Plantes in Paris. It was once found over much of North Africa, at least as far east as Egypt, where it was a mythological and sacrificial beast. However, by the 1900s its range was limited to Algeria and the Moroccan High Atlas mountains. Hunting throughout the 19th century drastically reduced the Bubal Hartebeest’s numbers, sealing its fate. A fawn-coloured animal that stood almost 4 feet at the shoulder, the Bubal Hartebeest was characterised by lyre-shaped horns that almost touched at the base. A beautiful beast, sadly missed.

7. The Thylacine

It was 1936 when the last Thylacine took its final breath in Hobart Zoo, Tasmania. Or so we think. Extremely rare if not extinct on the Australian mainland by the time of European colonisation, the Thylacine survived on the island of Tasmania alongside close cousins like the Tasmanian Devil. There, this distinctive, large-jawed beast found itself with a price on its head, as settlers blamed it for attacks on their sheep. The Thylacine was hunted to extinction by bounty hunters and farmers, though other factors such as disease, the introduction of wild dogs, and human encroachment into its habitat may have also played a part in the tragedy.

Although commonly known as the Tasmanian Tiger or Tasmanian Wolf, the Thylacine was neither feline nor canine: while striped like a tiger and sharing various features with large dogs, this marsupial carnivore was wholly unrelated – and with the pouch to prove it. A favourite in cryptozoological circles, there have been numerous sightings of the Thylacine since 1936 – which continue to this day – though none have yet been confirmed. It will be a rare coup for Mother Nature if another Thylacine is ever discovered; otherwise its most vivid memory will sadly survive in little more than photographic form – another dead hero of the natural world.

The Elusive Beauty of Lunar Rainbows

When the moon is near its fullest, and barely a cloud veils its face, certain locations on earth treat observers to the scarcely seen light phenomenon known as the lunar rainbow, or moonbow. Like daytime-occurring rainbows, moonbows are formed when rays of light bounce off water droplets suspended in the air – the vapour of a raincloud, say, or the spray from a thundering waterfall – though of course they are caused not by the direct light of the sun but by that which is reflected by the moon.

Like their diurnal counterparts, moonbows always appear in the part of the sky opposite the celestial body that provides their light source, with the moon thus positioned behind the viewer. Except for those lunar bows whose medium is the mist of waterfalls, a rare combination of a low moon and a dark sky are needed to create this spectacular sight – not to mention rainfall up ahead.

Even with the moon at its brightest, moonbows are faint compared to typical rainbows due to the low quantity of light shone down by our only satellite. The glow is too weak to stimulate the colour receptors of the naked eye – meaning moonbows are often seen as being white – so it’s lucky long-exposure photography has stepped in, enabling us to see all the colours of the moonbow.

Photographers have written reams about how best to capture this singular phenomenon. Tips include the use of a tripod, switching to manual focus, and bracketing exposure time to avoid a white blur, with looking for your shadow, and starting with a fresh roll of film and batteries among other pointers mentioned.

Of course, you’ve also got to know where to find moonbows, since there are only a small number of places in the world where they regularly materialise. Victoria Falls on the border between Zambia and Zimbabwe, Cumberland Falls in Kentucky, Yosemite Falls in California, and Waimea on Hawaii are some of the best known.

Yosemite is such a hotspot for viewing moonbows that a team of astronomers at Texas State University were inspired to develop a computer programme which can reliably predict when moonbows are likely to appear at the falls of America’s famous national park – other factors such as a clear sky permitting.

People have been watching moonbows since Aristotle’s day – and doubtless long before – but this research is the first time anyone has calculated precise dates and times for their appearance. Now it is hoped we may better appreciate this incredible yet elusive natural wonder.

Let’s leave with the words of naturalist and pioneering environmentalist John Muir in an extract from his 1912 book, The Yosemite, which describes the great man’s experience of a moonbow: “This grand arc of color, glowing in mild, shapely beauty in so weird and huge a chamber of night shadows, and amid the rush and roar and tumultuous dashing of this thunder-voiced fall, is one of the most impressive and most cheering of all the blessed mountain evangels.”
