Chilean volcanoes: shaken, but not always stirred?

The earthquake, which is estimated to have had a magnitude of 8, had an epicentre close to Valdivia, and was accompanied by significant ground shaking and subsidence as far south as Chiloe island, and a major tsunami that reached Hawaii.  The eyewitness reports of the time have been well ...[Read More]

Geology Photo of the Week # 10 – Nov 4-10 – A Mysterious Monster!

I apologize for the delay posting this. I was in Washington DC earlier this week to take in a Supreme Court hearing that never actually happened due to Hurricane Sandy. My flight out was also delayed and thus many other things in my life are delayed right now including this post. This photo poses a bit of a conundrum…since I don’t have a clue what it is! I have an idea, but I’d l ...[Read More]

Water Series (2): Fluoride Contamination in Drinking Water

This week, as part of our ‘water series’ we will focus on fluoride contamination in drinking water. In some parts of the UK we add fluoride to our drinking water, because small amounts can help to protect your teeth. However, too much fluoride (>1.5mg/L) can lead to a serious medical condition called fluorosis, affecting the development of teeth and bones. This strong dosage dependency can lead ...[Read More]

Friday Photo (55): Photos from Industry – Man Operating Machinery at a Mine in China

Man Operating Machinery at a Mine in Anhui Province, China There are many large mining operations covering Anhui Province, China. They tend to have limited safety regulations. The mines can ruin the landscape, cause pollution and can be dangerous places for people to work. However, this primary industry is fuelling China’s rapid growth and development. Our Friday Photo series will be focused ...[Read More]

Water Series (1): The Quantity and Quality of Groundwater

The water available in or near your home can vary dramatically over short distances. In Manchester, there is a robust supply of fresh water from the Lake District, whereas in London (only 200 miles away) the water has passed through limestone, leaving it with a cloudy taste and causing limescale build-up. Signs up on the London underground at the moment are encouraging people to save water by taki ...[Read More]

Friday Photo (54) – Debris Flow Channel, Gansu Province, China

Southern Gansu Province, China: Poorly Maintained Debris Flow Channel This channel is designed to transport debris flow material away from the road, thus preventing a major road blockage. The poor design and maintenance of the channel, however, is resulting in material coming down the channel and then being pushed back on to the road. (c) Geology for Global Development, 2012

Geology Photo of the Week #9 – Oct 21-27

Check out this wicked awesome rock!! This awesome formation is aptly known as “Split Apple Rock”. It is probably one of the more unique rock formations that I have seen.
