Most dangerous job in the world: Incredible footage of men working on top of volcanos This incredible footage shows men working on a super volcanic mountain range in East Java, Indonesia. The workers, many of whom aren't expected to live past 50, breathe highly noxious gases which come out of the Kawah Ijen Volcano without masks, carrying loads of up to 70kg on their backs from a quarry. Many work shirtless and have huge growths on their backs from the heavy loads. Photographer Brad Ambrose captured the pictures along with his pal Geoff Mackley, while trekking through Indonesia. The 38-year-old photographer said: "It would be one of the more dangerous jobs in the world – not just because of the fall risks, but because of the gases the miners work in.

Earth - Why ancient myths about volcanoes are often true Story has it that many hundreds of years ago, Tanovo, chief of the Fijian island Ono, was very partial to a late afternoon stroll. Each day he would walk along the beach, watch the sun go down and undoubtedly contemplate this paradise on Earth. The cultural memory was right, and our scientific surveys were wrong But one day Tanovo’s rival, chief of the volcano Nabukelevu, pushed his mountain up and blocked Tanovo’s view of the sunset.

Plate tectonics - Simple English Wikipedia, the free encyclopedia The tectonic plates of the world were mapped in the second half of the 20th century. Tectonic plates on a different map projection Global plate tectonic movement global earth history This presentation uses a series of paleogeographic and plate-tectonic reconstructions to show the broad patterns of Phanerozoic Earth history. Organization is by region and in geologic order from oldest to youngest for each region. The Time Slice link shows all maps and globes of all regions by geologic time (the Periods). Menu

Earth - The world's most deadly volcanoes Last August, in southern Iceland, the flanks of the volcano Bardarbunga ripped open and fountains of lava spouted skyward. Molten rock oozed downhill making its way toward the sea. The eruption has now come to an end but the volcano continues to pump gases into the atmosphere. Scientists are still monitoring it closely. All the World's Volcano Webcams Never in the history of volcanology have so many volcanoes been monitored. We have the ability to sit and watch hundreds of volcanoes as they sleep, rumble or erupt — all from the comfort of our homes or offices. This instant connectivity to volcanoes in some of the most remote parts of the world is what gives us the impression that there are more volcanic eruptions today than in the past. There really aren’t more, but rather we hear about or see the eruptions much faster. With the network of webcams and the peering eyes of satellites, almost no volcano can erupt on the planet and we not notice.

Earthquake - Simple English Wikipedia, the free encyclopedia Earthquakes are usually quite brief, but may repeat over a period of time. They are the result of a sudden release of energy in the Earth's crust. This creates seismic waves, which are waves of energy that travel through the Earth. Global risks: Pool knowledge to stem losses from disasters Turjoy Chowdhury/Nurphoto/Corbis This year's deadly earthquakes in Nepal killed more than 8,000 people and reduced thousands of buildings to rubble. In April and May, two massive earthquakes in Nepal killed more than 8,400 people, injured 20,000 and reduced 300,000 houses to rubble. In March, Cyclone Pam destroyed homes, schools, infrastructure and livelihoods on the Pacific island of Vanuatu, affecting half the population, including 82,000 children.
