Anatomy of an earthquake – Professor Iain Stewart
Saharan dust, traffic fumes and smog from Europe may be clogging up London’s air at present – and causing alarm in the newspapers – but in the world’s most polluted city London’s air would be considered unusually refreshing. That city is Delhi, the Indian capital, where air quality reports now make essential reading for anxious residents.
So why aren’t we all driving round in hydrogen-powered cars, moving our goods in hydrogen-powered lorries, and heating our homes and offices with this wonder element?
Officials say planes have taken food, water and medical supplies to Tanna island, which was directly in the path of Cyclone Pam.
Some great footage of plate tectonics in action!
A level wider reading and GCSE help with the 3 P’s. California’s long-term earthquake forecast, the first in seven years, has been released. The study, known as the Third Uniform California Earthquake Rupture forecast, teams the US Geological survey with three other state authorities on tectonics to work out the region’s risk from earthquakes.
The Villarrica volcano in southern Chile erupted in the early hours of Tuesday morning, spewing ash and lava up to 1,000m (3,300ft) into the air.
A lovely article comparing Haiti to Japan, fits really well into the Restless Earth topic and a great read for revision for A/A* students. Also good wider reading for A level.
Iceland is rising at a faster pace as global warming melts the island’s ice caps, scientists say. We learnt several of the waterfalls we visited in Iceland were a result of isostatic rebound. This article takes this into more depth.
Scientists who study ideas to engineer the climate to mitigate global warming say we should be ready to deploy an armada of instrumentation when Earth has its next major volcanic eruption. Good wider reading for A* GCSE and A2 geographers alike.
Without being able to drill into the heart of the Earth, its make-up is something of a mystery.
Research from China and the US suggests that the innermost core of our planet has another, distinct region at its centre.
“The new island is more than one kilometer (0.6 mile) wide, two kilometers (1.2 miles) long and about 100 meters (328 feet) high”
Geo-engineering: This is the so far unproven science of intervening in the climate to bring down temperatures.
Last month, the World Meteorological Organization released provisional figures that predicted the past 12 months were set to be record breakers.
The long-term global average temperature is calculated from data collected between 1951 and 1980.
Thousands of homes are still without power and more disruption was expected as the second of two storms is due to hit.
Hundreds of residents lose their homes as the eruption of Pico do Fogo destroys two villages. A brilliant case study of the disadvantages of living near a volcano.
TED TALKS are a fantastic resource at A level.
A quick read on the use of ice cores to reconstruct paleoclimates (climates of the past).
NASA Global climate change website. Worth checking out for your wider reading around climate change and cold environments.
A fantastic A level geography site on Antarctica covering many of our topics to improve our synopticity and get us ‘Thinking like geographers!”.
