Amazing Natural Events

We have gathered some of the most amazing events that has occurred within our earth and brought them to one page.

Chile Volcano Plume Explodes With Lightning

Ash from the Puyehue volcano in Chile covers a ski resort in Argentina and spectacular electrical storms light up the Puyehue-Cordón Caulle range after the long-dormant volcano erupted on June 11th 2011, belching an ash cloud more than six miles high over the Andes.

Niagara Falls lit up in neon colours during a light show

These spectacular pictures of Niagara Falls show its natural beauty lit up with brilliant neon lights.

The cascading curtain of water looks particularly magical at night, with the spray glowing bright pink, blue and yellow against the dark sky as it crashes into the river below.

Photographer Rajeev Nair, from Connecticut, US, captured the extraordinary pictures of the annual light show by spending hours at the world famous landmark.

Cappuccino coast

It was as if someone had poured tons of coffee and milk into the ocean, then switched on a giant blender. Suddenly the shoreline north of Sydney were transformed into the Cappuccino Coast.

Foam swallowed an entire beach and half the nearby buildings, including the local lifeguards’ centre, in a freak display of nature at Yamba in New South Wales. One minute a group of teenage surfers were waiting to catch a wave, the next they were swallowed up in a giant bubble bath. The foam was so light that they could puff it out of their hands and watch it float away.

Scientists explain that the foam is created by impurities in the ocean, such as salts, chemicals, dead plants, decomposed fish and excretions from seaweed. All are churned up together by powerful currents which cause the water to form bubbles.

These bubbles stick to each other as they are carried below the surface by the current towards the shore. As a wave starts to form on the surface, the motion of the water causes the bubbles to swirl upwards and, massed together, they become foam.

The foam “surfs” towards shore until the wave “crashes”, tossing the foam into the air

Shelf Cloud Over Saskatchewan

Perhaps it’s time to go inside. Such thoughts might occur to people witnessing the approach of an impressive shelf cloud.

Shelf clouds are typically seen leading thunderstorms, although they may precede any well defined front of relatively cold air.

Shelf clouds differ from roll clouds because shelf clouds are attached to a larger cloud system lurking above. Similarly, shelf clouds differ from wall clouds because wall clouds typically trail storm systems.

The above pictured shelf cloud was photographed toward the southwest during a trip crossing the prairies of Saskatchewan, Canada on the Trans-Canada Highway in 2001 August. A rising Sun illuminated the impressive cloud from the east as it advanced from the west.

Northern Lights

The bright dancing lights of the aurora are actually collisions between electrically charged particles from the sun that enter the earth’s atmosphere.

The lights are seen above the magnetic poles of the northern and southern hemispheres. They are known as ‘Aurora borealis’ in the north and ‘Aurora australis’ in the south..

Auroral displays appear in many colours although pale green and pink are the most common. Shades of red, yellow, green, blue, and violet have been reported. The lights appear in many forms from patches or scattered clouds of light to streamers, arcs, rippling curtains or shooting rays that light up the sky with an eerie glow.

The Northern Lights are actually the result of collisions between gaseous particles in the Earth’s atmosphere with charged particles released from the sun’s atmosphere. Variations in colour are due to the type of gas particles that are colliding.

The most common auroral color, a pale yellowish-green, is produced by oxygen molecules located about 60 miles above the earth. Rare, all-red auroras are produced by high-altitude oxygen, at heights of up to 200 miles. Nitrogen produces blue or purplish-red aurora.
