Features from the field: Strike Slip Faults Classification

Features from the field: Strike Slip Faults Classification

A strike slip faults is a fault on which most of the movement is parallel to the fault strike (Bates and Jackson, 1987). The term ‘wrench fault’ is also popularized in some researchers. Sylvester (1988) suggest not using wrench fault term for defining strike slip fault as general term because wrench fault was defined by Anderson (1905) as deep seated, regional and vertical faults. Many major strik ...[Read More]

Image of the Week – A high-resolution picture of Greenland’s surface mass balance

Image of the Week – A high-resolution picture of Greenland’s surface mass balance

The Greenland ice sheet – the world’s second largest ice mass – stores about one tenth of the Earth’s freshwater. If totally melted, this would rise global sea level by 7.4 m, affecting low-lying regions worldwide. Since the 1990s, the warmer atmosphere and ocean have increased the melt at the surface of the Greenland ice sheet, accelerating the ice loss through increased runoff of meltwater and i ...[Read More]

Minds over Methods: Reconstruction of salt tectonic features

Minds over Methods: Reconstruction of salt tectonic features

What is the influence of salt tectonics on the evolution of sedimentary basins and how can we reconstruct such salt features? Michael Warsitzka, PhD student at the Friedrich Schiller University of Jena, explains which complementary methods he uses to better understand salt structures and their relation to sedimentary basins. Enjoy!   Reconstruction of salt tectonic features from analogue mode ...[Read More]

Image of the Week – The ups and downs of sea ice!

The reduction in Arctic sea-ice cover has been in the news a lot recently (e.g. here) – as record lows have been observed again and again within the last decade. However, it is also a topic which causes a lot of confusion as so many factors come into play. With this Image of the Week we will give you a brief overview of the ups and downs of sea ice! In general, Arctic sea ice is at its minim ...[Read More]

A year at the South Pole – an interview with Tim Ager, Research Scientist

A year at the South Pole – an interview with Tim Ager, Research Scientist

What is it like to live at the South Pole for a year?  A mechanical engineer by trade, Tim Ager, jumped at the opportunity to work for a year as a research scientist at Amundsen-Scott South Pole Station.  When not traveling on various adventures he lives in Austin, Texas, and recently took the time to answer a few questions about his time at Pole. What goes on at Amundsen-Scott South Pole Station? ...[Read More]

Image of the Week — Microbes munch on iron beneath glaciers

The interface between a glacier and its underlying bedrock is known as the subglacial zone. Here lie subglacial sediments, the product of mechanical crushing of the rock by the glacial ice. Despite their lack of sunlight, nutrients and oxygen, subglacial sediments host active and diverse communities of microorganisms. What we (don’t) know about subglacial microorganisms The past few decades ...[Read More]

Report from the Spring School on “Statistical analysis of hyperspectral and high-dimensional remote-sensing data using R”, Jena, Germany, March 13-17, 2017

The Spring School on “Statistical analysis of hyperspectral and high-dimensional remote-sensing data using R” was organized by the GIScience group lead by Prof. Alexander Brenning and two researchers from his GIScience research group, Patrick Schratz and Dr. Jannes Münchow. The school brought together a diverse group of 28 researchers (e.g. geoscientists, forestry, environmental studies) at differ ...[Read More]

EGU Seismology Division 2017 visibility survey

Dear Seismology Division blogpost, Facebook and Twitter followers, The EGU Seismology Division has prepared an online survey to investigate how members are following our division’s activities online. The data we will acquire through this simple survey allows us to learn how we can improve our visibility and to which activities we could further focus. The results will NOT be used for any comm ...[Read More]

Image of the Week – Ice on Fire (Part 2)

This week’s image looks like something out of a science fiction movie, but sometimes what we find on Earth is even more strange than what we can imagine! Where the heat of volcanoes meets the icy cold of glaciers strange and wonderful landscapes are formed.  The Kamchatka Peninsula, in the far East of Russia, has the highest concentration of active volcanoes on Earth. Its climate is cold due ...[Read More]
