An angular unconformity is an erosional surface that truncates older, tilted sedimentary layers and that is overlain by younger layers, oriented parallel to the unconformity. The discovery and interpretation of angular unconformities, like the famous Hutton’s unconformity at Siccar Point, Scotland, marked a paradigm shift in the geological theories of the 18th century. At that time, the theo ...[Read More]
For any field-based seismologist, there is nothing more satisfying than standing in a remote location, laptop in hand finalising the installation of a new broadband seismic station. In 2013 this feeling was amplified as we deployed the first, and still the only broadband seismic array in the Democratic People’s Republic of Korea (DPRK, the formal name for North Korea). That it took almost two year ...[Read More]
One of the major motivations behind research into solar-terrestrial physics is the potential consequences of space weather on our technologically dependent society. Given this risk, recognised by many governments around the world, it is a little concerning that a sizable fraction of the public have never even heard of the term “space weather” – for example a recent public dialogue in the UK showed ...[Read More]
While many of us are experienced in giving presentations before a variety of audiences, for some, the switch to a remote presentation format can be daunting. With this in mind, and based on our experiences at sedsonline.com I have put together the following tips for our community – these are in no way exhaustive, but I do hope that you find them useful and I welcome any feedback or comments. Happy ...[Read More]
Women make up 50.8% of the worlds population, yet fewer than 30% of the world’s researchers are women. Of this percentage, BAME (Black Asia and Minority Ethnic) comprise around 5%, with less than 1% represented in geoscience faculty positions. The divide between women in the population and women in STEM needs to be addressed. Through a series of blog posts we hope to raise the voice of women in th ...[Read More]
Sea level rise is one of most dreadful consequences of anthropogenic (caused by humans) global warming. It is estimated that the loss of coastal infrastructure alone would cost the global economy more than 1 trillion dollars per year by 2100 [1]. This number is based on climate models, but these are only as good as our current understanding of the sea level rise. Therefore, researchers are monitor ...[Read More]
With his dazzling wit, charm and handsome moustache, Groucho has an engagements calendar that would make the most sparkly socialite jealous. He therefore asks: Should you ever turn down an invited presentation? Dear Groucho, If being dead since 1977 isn’t enough to get you out of an awkward invited spot, I recommend you follow your own advice: I refuse to join any club that would have me as ...[Read More]
As well as August, September was not highlighted by a large event (> M 7). The TOP 3 strongest earthquakes which occurred during this month correspond to a strike-slip earthquake in the Mid-Atlantic Ridge (M 6.9), an interplate EQ in central-north Chile (M 6.8), and another EQ in a different segment of the Mid-Atlantic Ridge (M 6.7). Furthermore, the largest event in Europe occurred on Septembe ...[Read More]
The first days of October were marked by an extreme weather event: storm Alex, a cyclone of Atlantic origin, caused massive showers and thunderstorms over Provence, the Alps, Piedmont and Liguria. In these regions, numerous historical records of precipitation were broken causing the flooding of several streams and rivers in which many people lost their lives. Economic damage was also significant a ...[Read More]
Nowadays geodynamics can involve a lot of 3D data which has to be analyzed. This week Oliver Kreylos, a researcher with the UC Davis W.M. Keck Center for Active Visualization in the Earth Sciences (KeckCAVES) and the UC Davis DataLab, shows us an alternative to looking at 3D data or models on a 2D screen: looking at them in full 3D through virtual reality! One problem in studying Earth’s dee ...[Read More]
