Three Gorges “Disaster”
There are fears that China's Three Gorges Dam is causing serious environmental problems eg landslides that have triggered 50 metre-high waves on the reservoir behind the dam. These landslides are being caused by the huge weight of water behind the dam and fluctuations in the water level.
Last week, a landslide in Badong County in Hubei Province, alongside the reservoir, killed more than 30 people after burying a bus. China now insists that there have been no unforeseen environmental problems related to the project, due for completion in 2009. Read the rest here of this BBC article.

Etna erupts
Sicily's Mount Etna provided a spectacular show of fire and lava on Friday night as it erupted. No commentary but a good light show here as Etna erupts. Watch the video here.
Famous volcanoes
Vesuvius is a cone volcano which is currently dormant but has been very destructive and in AD 79 it erupted and resulted in the destruction of Herculaneum and Pompeii. Thousands of people were killed instantly by pyroclastic flows (most didn’t even see it coming). The area was buried under meters of ash. This is a youtube video here which can’t be embedded but I’ve put the link here. It is quite long but very good.
Mt St Helens
A more up to date eruption but still as strange. This will be good for S2 as you will have to do a newspaper report on this eruption or an earthquake of your choice (!!), probably San Francisco 1906 for homework. If you are reading this you get an extra length of time to do it. Well done! Don’t tell the rest of the class - just smile in class and you and I will know your secret. Short video here.
Look also at the brilliant Rob Chambers links on Mt St Helens at this link to help you investigate this.
Here's also a wee Penalty Shoot out game to revise this! Don’t get carried away and only play then forget your homework. Also another game here. Have fun!
After your homework you may want to have a go at this game.This is from the ISDR (International Strategy for Disaster Reduction) and has many disaster simulations for you to try. For now just start with the earthquake disaster and see how well you get on with managing your population. This game will help you to think what governments might do during an earthquake and some of the decisions they have to make.

Bangladesh cry for clean water
A week after the cyclone hit Bangladesh the main aim now is to supply the people with clean water and prevent the spread of disease, but this is a difficult task. There are relatively few tube wells in the area. One major advantage of tube wells, where water is pumped to the surface through a narrow tube, is that they are not easily contaminated. But much of the surface water people are relying on has been contaminated, either by the bodies of dead livestock or - in coastal areas - by high salinity( salt content) caused by the tides after the storm.
Many warn that people are suffering from diarrhoea. This KILLS! The main fear among aid workers is that of water-borne diseases, chief of which is cholera. Read the rest here.

Bangladesh rescue effort goes on
Rescuers are continuing efforts to try to reach people hit by a powerful cyclone that tore through southern Bangladesh killing at least 2,000. Cyclone Sidr destroyed or damaged tens of thousands of homes, brought down power lines and wiped out vital crops.
Helicopters and ships are being used to get food and clean water to thousands.
Thousands of soldiers have joined international agencies and local officials in a massive relief operation, but debris and floods are hampering their efforts. Britain, Germany and the European Union have offered several million dollars in relief aid and the World Food Programme is rushing in food supplies. Read this here.

Bangladesh cyclone kills more than 600
At least 600 people are reported to have died after a powerful cyclone smashed into Bangladesh's coast, levelling villages and uprooting trees.
Hundreds of thousands of people were evacuated or sought safe shelter before the storm hit the coast from the Bay of Bengal, but some were left behind.
A cyclone that slammed into Bangladesh's coast with 150 mph winds killed at least 242 people, levelled homes and forced the evacuation of 650,000 villagers before heading inland and losing power today, officials said.
Tropical Cyclone Sidr roared across the country's southwestern coast late Thursday with driving rain and high waves. Most of the dead were killed by falling debris, according to Nahid Sultana, an official at a cyclone control room in the capital, Dhaka. Read here and here

Japan's new quake detection system
Predicting when an earthquake will take place is still just about impossible.
But Japanese scientists say they have come up with the next best thing.
They have developed a warning system that can alert you before the shaking starts.
In Japan earthquakes are a constant danger. On an average day there are three strong enough for you to feel.
Japan has an unrivalled network of seismic sensors, more than 4,000 of them, some deep below the Earth's surface. Click photo for link.

Powerful quake hits north Chile
A powerful 7.7-magnitude quake has hit north Chile, cracking roads, bringing down buildings and knocking out power. The quake - lasting about 50 seconds - sent panicked residents out into the streets. It could even be felt in the capital Santiago, 1,260km to the south. Click picture as link.
Chile rattled by big aftershocks
Northern Chile has been rattled by powerful aftershocks a day after an earthquake struck the region, leaving 15,000 people homeless. Thursday's two tremors were measured at 6.2 and 6.8 magnitude by the US Geological Survey.
The major 7.7 magnitude quake wrecked 4,000 homes and other infrastructure.
Tents have been set up to help residents who were forced to sleep outdoors under cold desert skies.
Lasting about 50 seconds, the earthquake was felt thousands of kilometres away in Sao Paulo, Brazil. Electricity, water and phone lines were cut in some areas by the quake, which struck around midday on Wednesday 1,260km (780 miles) north of the capital, Santiago. Click photo as link

Panic fear as Japan to issue alerts before quakes hit
JAPAN, which is prone to earthquakes, is to issue pre-emptive warnings of approaching big tremors, to reduce casualties and damage - although some fear the new system will lead to panic. It could also prompt trains, lifts and factories to stop operating, limiting damage in Japan, where 20 per cent of the world's big quakes are recorded and where Tokyo is said to be long overdue for a major tremor. The Tokyo city government has said an earthquake in the capital of a similar magnitude to Kobe could kill more than 7,000 people and injure close to 160,000. What do you think – a good idea or not?

Deadly earthquake hits Indonesia
An earthquake measuring 8.2 on the Richter scale has hit Indonesia, killing at least ten people and injuring dozens more.
The quake, which was centred six miles deep off the Sumatran coast, triggered a three-metre tsunami and led to tsunami warnings.
A second tsunami warning was issued when an aftershock measuring 6.6 hit the area three hours after the original quake.
Most of the tsunami alerts were later lifted in the area.
People were reported to be trapped in collapsed buildings in the area. The quake also cut off phone lines and electricity supplies.
The quake was powerful enough to be felt by people in high-rise buildings in Malaysia, Singapore and Thailand.
The December 26 2004 tsunami, which killed more than 220,000 people, was triggered by a 9.0 magnitude quake in the same region. Indonesia was the worst-
Indonesia, the world's largest island group, is prone to this type of damage due to its location on the so-called Ring of Fire, a circle of fault lines around the Pacific Ocean.

Hurricane Felix
Hurricane Felix Kills 150
Desperate families and rescue workers were scouring the Central American coasts after record breaking hurricanes left more than a hundred and fifty people dead or missing Following Hurricane Dean last month, this is the first time since records began that two Category 5 hurricanes have hit land in one year.
Winds and heavy rains caused mudslides, destroyed homes, uprooted trees and devastated villages in Nicaragua. Much of the damage has occurred in isolated places and as rescue workers reach those areas there are fears that the death toll will rise. Schools and ports were closed today on the north-west Mexican coast, the hurricane has been downgraded to a tropical storm but could still cause flash-flooding and mudslides. The storm is expected to reach the United States later, but it should have lost most of its energy by the time it dumps a little more rain on New Mexico.

Warning of tsunami that could dwarf 2004 disaster
The pictures here show Indonesia Before and after the tsunami of 26th December 2004. The results are devastating but what is more scary is thr thought that it could happen again. 250,000 people died in 2004. Tens of millions of people who live in the Bay of Bengal face the threat of a tsunami as massive as the one that devastated the Sumatran coast in 2004. Satellite measurements now suggest the plates are pushing together. If there is a sudden release of stress, the resulting upward movement of the sea floor in the Bay of Bengal could cause a "giant tsunami" that would reach the Ganges Delta in a couple of hours, where 60 million people live within 10 metres of sea level. An expert said that the earthquake itself could be as big as magnitude 9.0 and cause devastation in the northern tip of the Bay of Bengal. "It is difficult to dispute the evidence," he said, adding that the earthquake that triggered the 2004 tsunami had, "if anything probably increased the risk" of a quake in the identified risk region.
Hurricane Felix rips through Caribbean
THE HIGHLY dangerous Hurricane Felix ripped into Central America yesterday, smashing up a port on Nicaragua's Caribbean coast and threatening deadly mudslides in Honduras and Guatemala.
Two people were reported dead in a port in northern Nicaragua, where strong winds tore the roofs off homes and badly damaged a church
Uprooted trees flew through the air as thousands took shelter in two schools in the port, home to some 30,000 Indians.

Have a look at the photos to see the damage done by this hurricane. Aren't you glad we don't get these? Why do you suppose we don't get them?
