< Etna (VolcanoEtna.com)
MOUNT ETNAThe volcano Etna (3,329 metres, 10,922 ft) at Italian island of Sicily is one of the most active volcanoes in the world. In 396 BC, an eruption of Etna is said to have thwarted the Carthaginians in their attempt to advance on Syracuse during the First Sicilian War. Since the year 1600 A.D., there have been at least 60 flank eruptions and countless summit eruptions; nearly half of these have occurred since the start of the 20th century, and the 3rd millennium has seen five flank eruptions of Etna so far, in 2001, 2002-2003, 2004-2005,2007 and 2008.

In the top-10 of the World's worst floods by death toll (Epic Disasters) China has the first six mentions. In the first four cases it was the Huang He, the Yellow River (Map), that came far out if its watercourse. One of the major reasons for the flooding is the high silt content that gives the river its yellow tint (and thus its name). The silt—which constitutes as much as 60% of its volume—builds up until the river actually is higher than the surrounding land. The tendency to flood is exacerbated by ice dams which block the river in Mongolia; the dams back up the water, and then release devastating walls of water when they break. The history of flooding has prompted the Communist Chinese government to embark on a program of building dams for flood control. The dams, however, have not proven entirely effective and have been the target of criticism from environmentalists.
Worst floods: 1. Huang He (Yellow) River, China (1931) 1,000,000 to 3,700,000 causualties | 2. Huang He, China (1887) 900,000 to 2,000,000 | 3. Huang He, China (1938) 500,000 - 900,000 Nationalist Chinese troops under Chiang Kai-Shek when they broke the levees in an attempt to turn back advancing Japanese troops. | 4. Huang He, China (1642) 300,000 Chinese rebels destroy the dikes along the city of Kaifeng, flooding the surrounding countryside. | 5. Ru River, Banqiao Dam, China, (1975) 230,000 Collapse of the Banquia Dam (and others), following a heavy rain caused by a typhoon. Worst dam related collapse in history. | 6. Yangtze River, China (1931) 145,000 The Yangtze has had more than 1,000 recorded floods. | 7. The Netherlands and England (1099) 100,000 Storm and high tides in Thames and flood North Sea | 8. The Netherlands (1287) 50,000 A seawall on the Zuider Zee failed. | 9. Neva River, Russia (1824) 10,000 Ice dam clogged the Neva, flooding nearby cities. | 10. The Netherlands (1421) 10,000 North Sea storm flooded wide area in South Holland in this St. Elisabethsvloed. (Epic Disasters)

MAGNITUDE 9.3 - WORST IN HISTORY?An undersea earthquake on December 26, 2004, with a magnitude to 9.3 and an epicentre off the west coast of Sumatra, Indonesia, caused the Asian Tsunami, that inundated the coasts of Indonesia, Malaysia, Thailand, Myanmar, Bangladesh, India and Sri Lanka. More than 250,000 people were killed.

The tsunami display usually is empty. That is favourable. It means: at this moment tsunami is not a 'trend' at Twitter. If, however, any tsunami hits any coast, you'll find here a lot of 'hot' information.
Islands of volcanic origin, such as the Canaries, have an especially large potential for triggering a tsunami. That the Canaries constitute a danger was shown 300,000 years ago when a part of the island El Hierro slid into the sea, triggering a mega-tsunami which carried rocks as high as a house for many hundreds of metres into the interior of the east coast of what is today the USA.
The danger of a similar island collapse is seen by scientists particularly at the island of La Palma in the Canaries. Here, following a volcanic eruption in 1949 almost half of the mountain range of 20 km moved westwards towards the sea, leaving a large tear in the volcanic basalt. In the event of a fresh eruption, a huge part of the volcano could loosen itself due to differences in the types of rock and diverse water deposits within the now active volcano. As a result, the densely populated east coast of America would be massively threatened.
According to a computer simulation by Stephen N. Ward and Simon Day, a tsunami (purple-red on the graphics) would rush across the Atlantic if the slopes of the Cumbre Vieja volcano were to collapse into the sea.
After the Asian tsunami of Cristmas 2004 the possibility of a Palma tsunami caused a media hype. The dangers described, however, were convincing denied.
