Tsunami Alert Called Off

A tsunami watch in place for three Central American countries after a 7.1 magnitude quake struck off Honduras has been called off.
The Pacific Tsunami Warning Center said the danger of a tsunami hitting Belize, Guatemala and Honduras had now passed.
The powerful quake hit 64km (39 miles) north-east of Roatan on Honduras' Isles de la Bahia in the Caribbean Sea, the US Geological Survey (USGS) said.
There were no immediate reports of major damage or mass casualties.
The quake struck at 0324 local time (0824 GMT) at a relatively shallow depth of 10km(six miles).
Tremors were felt in dozens of cities across the region and as far north as Cancun in Mexico, the USGS said.
People in Guatemala City ran into the streets in their pyjamas, the Associated Press news agency reports.
The Pacific Warning Center in Hawaii said that the danger of a major tsunami wave hitting the coastlines of nearby countries had now passed.
But it warned that boats and coastal structures could still be affected by rapid currents caused by the quake.

Italian Earthquake

At least 90 people are believed dead and tens of thousands homeless after an earthquake hit L'Aquila and other towns in central Italy, rescuers say.
About 1,500 people were injured and many people are still missing as rescuers search desperately for survivors trapped beneath rubble.
The 6.3-magnitude quake struck at 0330 (0130 GMT) close to L'Aquila.

Mount St Helens and Pyroclastic Flows

An excellent video from the BBC explaining how pyroclastic flows actually kill people and it also includes real time footage of the Mount St Helen's eruption of 1980. An excellent video providing further information on a popular case study.

Volcanic Eruptions in Tonga

An undersea volcano is erupting in the Tonga islands, shooting clouds of volcanic smoke, steam, and ash thousands of feet into the sky above the South Pacific ocean.
Authorities said Thursday the volcanic eruption does not pose any danger to Tonga islanders at this stage, and there have been no reports of fish or other animals being affected.
Spectacular columns are spewing out of the sea about 6 miles from Tonga's main island of Tongatapu—an area where up to 36 undersea volcanoes are clustered, geologists said.
Trade winds continued to blow volcanic gas and steam away from the island Thursday.
Taniela Faletau, deputy commander of the Tonga police force, said coastal villages close to the roiling ocean site were not yet at risk from the volcanic eruption. No warnings have been issued.
Coastal residents said the volcanic steam and ash column first appeared on Monday morning, after a series of sharp earthquakes were felt in Tonga's capital, Nuku'alofa.
The underwater volcanic eruption was taking place near the low-lying twin volcanic islands of Hunga Tonga and Hunga Ha'apai, within sight of Nuku'alofa.
Large amounts of pumice thrown up by the volcanic eruption would likely clog beaches on the southern coast of the nearby Fiji Islands within a short time, Mafi said.
Tonga, a 170-island archipelago about halfway between Australia and Tahiti, is part of the Pacific Ring of Fire—an arc of earthquake and volcanic zones stretching from Chile in South America through Alaska and down through Vanuatu to Tonga.

Urban Earth

“In 2008, the world reaches an invisible but momentous milestone: For the first time in history, more than half its human population, 3.3 billion people, will be living in urban areas. By 2030, this is expected to swell to almost 5 billion. Many of the new urbanites will be poor. Their future, the future of cities in developing countries, the future of humanity itself, all depend very much on decisions made now in preparation for this growth.” Watch these videos as they follow transects through major urban centres from around the world.

Super volcanoes

Yellowstone National Park in the USA is one of the best known locations of super volcanoes on the planet.



At Brecon High School we are lucky enough to have Dr John Grattan of the University of Aberystwyth come visit year 12 and year 13 students on February 9th 2009, to share his knowledge of super volcanoes. We look forward to his visit.

UN warning on brown pollution haze

Vast areas of Asia, the Middle East, southern Africa and the Amazon Basin, are affected by the smog-like plumes, caused mainly by the burning of fossil fuels and firewood, are known as "atmospheric brown clouds". Read more here.
