Iceland volcano eruption, butterfly effect and the Holy Quran..!
One slight flap of the wings of a butterfly in a South American tropical rain forest has the potential to cause a hurricane in a faraway country. This is the famous "Butterfly Effect". The concept has been obvious in the recent volcanic eruption in Iceland.
It had erupted after almost 200 years of silence.
The most direct hit sector is aviation. About 95-thousand flights were canceled between April 15th to the 20th. Experts estimate the aviation sector has lost 1.7 billion US dollars. Meanwhile industries related to aviation have also been affected, like logistics, tourism, and exports. Read More.

Quran says:
"and the earth will throw up all her burdens..." (The Holy Quran 99 : 2)
"Soon shall We show them Our Signs on the horizons and in their own beings until it becomes clear to them that it is the Truth. Is it not enough that your Lord is witness over everything?" (The Holy Quran 41 : 53)

Why the ash from the eruption of Eyjafjallajoekull volcano is dangerous?
The mushrooming cloud of ash from the eruption of the Eyjafjallajoekull volcano in Iceland had resulted in the closure of major airports throughout the U.K. and Scandinavia.
Remy Melina writes in MSNBC:
The grounded flights make sense, as these super-heated plumes can do more than reduce visibility. They're downright hazards for airplanes.
"Basically, planes and volcanic ash don't mix," Elizabeth Cory, a spokesperson for the Federal Aviation Administration, said today. "When ash is ingested into the engine, it creates problems for the plane, including electrical failure."
The thing that makes volcanic plumes so dangerous is that they look extremely similar to regular clouds, visibly and on radar screens. Even when ash isn't visible to the human eye, it can still pose a threat to aircrafts because of the chemicals floating within volcanic plumes.
Airborne ash makes air travel extremely dangerous and difficult for several reasons, the number one being that when the air that gets sucked through an aircraft's jet engine is mixed with ash, it can cause engine failure.
The ash particles that make up volcanic clouds contain powder-size to sand-size particles of igneous rock material that have been blown into the air by an erupting volcano. The tiny particles instantly melt when faced with the internal temperature of an in-flight jet engine, which exceeds 1,832 degrees Fahrenheit (1,000 degrees Celsius).
