The huge fold in the flank of the 2969 m high Dent de Morcles (in Waadtland Alps, Switzerland) is an impressive testimony to the collision between Africa and Europe (which began some 65 million years ago). The layers, originally deposited on the sea floor in a horizontal position, were compressed and shifted. The darker parts developed during the Tertiary period (66 million years ago). They are yo ...[Read More]

Last week at the 2016 General Assembly Sara, one of the EGU’s press assistants, had the opportunity to speak to Koen Van Noten about his research into how crowdsourcing can be used to find out more about where earthquakes have the biggest impact at the surface. Firstly, can you tell me a little about yourself? I did a PhD in structural geology at KULeuven and, after I finished, I started to ...[Read More]

When mountains collapse…

Jane Qiu, a grantee of the Pulitzer Center on Crisis Reporting, took to quake-stricken Nepal last month — venturing into landslide-riddled terrains and shadowing scientists studying what makes slopes more susceptible to failure after an earthquake. The journey proved to be more perilous than she had expected. What would it be like to lose all your family overnight? And how would you cope? It’s wit ...[Read More]

Often, in the news, we are used to seeing disaster statistics reported as isolated figures, placed into context by the tragic human cost of floods, earthquakes and drought. The recent Ecuadorian earthquake that occurred on Saturday the 16th April, for example, was described as having an estimated economic cost of $820 million, which could rise as the scale of the disaster is revealed. But beyond t ...[Read More]
