Imaggeo on Mondays: Stone Flower

Imaggeo on Mondays: Stone Flower

In a true feat of endurance, self-discovery and resilience, Solmaz Mohadjer and Josy Strunden, geology students at the University of Tübingen (Germany), cycled 800 km in the Pamir Mountains as part of a trip to raise awareness about autism in Tajikistan. ““We cycled through one of the most tectonically active regions on the planet, passing by mountain communities that welcomed us warmly as well as ...[Read More]

Imaggeo on Mondays: Fresh breakout in the lava fields

Kate Dobson was a volunteer at the Hawaii Volcano Observatory (HVO) in 2001/02 and revisited the stunning Big Island in 2006. During her holidays Kate ventured out to the coastal section of the Pu’uO’o lava flow field and captured this spectacular image of a fresh lava breakout. The Pu‘u ‘Ō‘ō vent is in the East Rift Zone of Kīlauea Volcano and began erupting on January 3, 1983, and has continued ...[Read More]

The known unknowns – the outstanding 49 questions in Earth sciences (Part III)

We continue exploring the biggest conundrums in Earth sciences in this third post of the known unknowns. In the two previous instalments of the series we’ve discovered what the major questions still to be answered about the early days of planet Earth and its inner workings are. We now move onto the planet’s surface. The advent of plate tectonic theory, arguably one of the biggest advancements in t ...[Read More]

GeoTalk: Matthew Agius on how online communication can help identify earthquake impact

In this edition of GeoTalk, we’re talking to Matthew Agius, a seismologist from the University of Malta and the Young Scientist Representative for the EGU’s Seismology Division. Matthew gave an enlightening talk during the EGU General Assembly on how communication on online platforms such as Facebook can help scientists assess the effect of earthquakes. Here he shares his findings and what wonders ...[Read More]

Imaggeo on Mondays: Fuelling the clouds with fire

Wildfires frequently break out in the Californian summer. The grass is dry, the ground parched and a small spark can start a raging fire, but burning can begin even when water is about. Gabriele Stiller sets the scene for a blaze beside Mono Lake, exploring the events that got it going and what it may have started in the sky…  While on shores of Mono Lake in the summer of 2012, I spotted something ...[Read More]

Geosciences column: Shelter island – building a barrier to protect the coast

The latest Geosciences Column features recent research into tsunami hazards and explains how island building out to sea can help protect buildings on the shore… Barrier reefs are well known for holding off the wrath of the ocean and sheltering the serene lagoons that stretch between them and the mainland. Barrier islands possess the same protective power, taking the impact of waves that have built ...[Read More]

Imaggeo on Mondays: Shaken, not stirred – sediment shows signs of past earthquakes

Nore Praet, a PhD student from Ghent University in Belgium, brings us this week’s Imaggeo on Mondays. She sets the scene for an investigation into past earthquakes and explains how peering through a lake’s icy surface and its murky waters, and into the sediment below can help scientists find out more about the impact of earthquakes in the future… Early this year, I set off with a group of scientis ...[Read More]

It’s not my fault

A line on a map is important. In the Beverly Hills region of Los Angeles a series of mapped fault lines are now the cause of a major controversy. Communities have been alarmed, money has been lost and legal proceedings are ongoing. It started in 1992. James Dolan and Kerry Sieh, two earthquake geologists at the California Institute of Technology, published a map in a field trip guidebook about the ...[Read More]

GeoTalk: Steven Smith on fossil faults and fantastic faulting

This week in GeoTalk, we’re talking to Steven Smith, a Lecturer from the University of Otago. Steven takes us on an Earth-shaking journey, explaining how ancient faults reveal what’s happening under the Earth’s surface and delving into the future of fault zone research. First, could you introduce yourself and tell us a little about what you are currently working on? Last September I started as a L ...[Read More]

People power

Seismic monitoring is critical in earthquake-prone areas such as Nepal, but limited resources mean limited monitoring. EGU Science Journalism Fellowship awardee Kate Ravilious reports back on how scientists are using social media to fill the gap.  Data gathering needn’t always involve expensive instruments or exotic fieldtrips. Here in resource strapped Nepal, seismologists are tapping into the po ...[Read More]
