Teks 1 Volcanic eruptions happen when lava and gas are discharged from a volcanic vent. The most common consequences of this are population movements as large numbers of people are often forced to flee the moving lava flow. Volcanic eruptions often cause temporary food shortages and volcanic ash landslides called Lahar. The most dangerous type of volcanic eruption is referred to as a ‘glowing avalanche’. This is when freshly erupted magma forms a hot pyroclastic flow which has temperatures of up to 1,200 degrees. The pyroclastic flow is formed from rock fragments following a volcanic explosion, the flow surges down the flanks of the volcano at speeds of up to several hundred kilometers per hour, to distances often up to 10km and occasionally as far as 40 km from the original disaster site. The International Federation response adjusts to meet the needs of each specific circumstance. As population movement is often a consequence, the provision of safe areas, shelter, water, food, and he...

Example of factual report Polar bears are also called ice bears. Though we see them as white bears, a research suggests that these bears evolved from grizzly bears about 150,000 years ago. When grizzly bears denned near the sea ice, some of them ventured onto the ice to hunt new foods. Polar bears’ habitat is on the Arctic sea ice, where most of their activities are done there. However, as the frozen ice is constantly changing, they need to adjust their movement on regular basis. Adult male polar bears can range from weights of 365 to 600 kilograms (800 – 1300 pounds) and stand 3 meters (10 ft) tall when they rearing up on their hind legs. The females are smaller, about half the size of the males. As carnivores (meat eaters), the main prey for polar bears are ringed seals, the most common seals in Arctic. As the ringed seals have small size, it is easy for polar bears to hunt and kill them. The other prey are bearded seals, which are commonly hunted by male polar bears. Some of t...
