Effective responses to natural disasters require the rapid acquisition of information about where has been affected, how many people are in the affected areas and what the magnitude of the damage is. This information is critical in both disaster and emergency rescue management. Indeed, the first three days after the onset of a disaster has …[Read More]

Imaggeo on Mondays: Wonderings and weathering
After studying ‘Applied Environmental Sciences’ I decided to go with a friend for six months to New Zealand for the southern hemisphere winter. Leaving as soon as my diploma thesis (on epiphytic lichens) was written, we set off into the distance to work and travel. We chose New Zealand as our dream destination because these …[Read More]
GeoTalk: Jane Robb
GeoTalk, featuring short interviews with geoscientists about their research, continues this month with a Q&A with Jane Robb from University College London (UCL), who tells us about the excitement of geo-outreach and importance of conserving heritage collections. First, could you introduce yourself and let us know a bit about your current work at UCL? Hi, …[Read More]
Imaggeo on Mondays: Scorching the soil
This week’s Imaggeo on Mondays is brought to you by the photographer himself, Antonio Jordán (Univerity of Sevilla, Spain), who describes the impact of forest fires on soil properties. This photo was taken while planning some field experiments: in the image, several water drops are resting on a surface soil layer without infiltrating. This process …[Read More]
Imaggeo on Mondays: Kalalau Valley
At over 5 million years old, the island of Kauai is the oldest island in the Hawaiian Achipelago. Hawaii, Maui and Oahu are all younger and lie further to the southeast. This island chronology is no coincidence – the Archipelago formed as a result of intra-plate volcanic activity. Intra-plate volcanism occurs where an upwelling magma …[Read More]
Geosciences Column: The contribution of climate change to water scarcity in the MENA region
In this month’s Geoscience’s column, Alex Stubbings discusses the water scarcity problems in the Middle East and North Africa region and the recent developments in modelling water resources here. The Middle East and North Africa (MENA) region is considered the most water-scarce region in the world. As such, the region faces a multitude of challenges …[Read More]
Geosciences Column: Hazard perception – how great is the risk of a rockfall?
In this month’s Geoscience’s column, Sara Mynott discusses the geological hazards associated with climate warming and how recent research sheds new light on our understanding of rockfall frequency. Rockfalls are the free-falling movement of bedrock material from a rock face, a phenomenon also encompassed by the terms ‘landslide’, ‘rockslide’ and ‘rock avalanche’. They range from …[Read More]
Imaggeo on Mondays: Rainbow in stone
Nothing better characterises the wild US West than endless landscapes of red hoodoos, spires of rock protruding from the bottom of an arid drainage basin or badland. Found mainly in desert and dry, hot areas, hoodoos are distinctive from similarly-shaped formations, such as spires or pinnacles, because their profiles vary in thickness throughout their length. …[Read More]
Imaggeo on Mondays: Amazonian floodplain
After the Nile, the Amazon River is the second longest river in the world and, by releasing up to 300,000 cubic metres per second into the Atlantic Ocean, accounts for approximately one-fifth of the planet’s total river flow. The river and its tributaries are characterised by extensive annual flooding of over 350,000 square kilometres of …[Read More]
Imaggeo on Mondays: Storm in Mount Waddington
This week’s Imaggeo on Mondays is brought to you by the photographer herself, Marion Bisiaux (now at Stendhal University, Grenoble, France), who tells us about her exciting field trip to the British Columbia’s Coast Range. This picture was taken during the Waddington Range Ice Core Project in which I participated during my PhD at the …[Read More]
