Imaggeo on Mondays: Winter threatens to freeze over fieldwork

This photo was taken during a fieldwork campaign following the mainshock of the deadly seismic sequence that struck central Italy starting from 24 August 2016. The magnitude 6.2 earthquake severely damaged nearby towns, claimed more than 290 lives and injured nearly 400 people in its wake. As a geologist from the National Institute of Geophysics …[Read More]

Is it an earthquake, a nuclear test or a hurricane? How seismometers help us understand the world we live in

Is it an earthquake, a nuclear test or a hurricane? How seismometers help us understand the world we live in

Although traditionally used to study earthquakes, like today’s M 8.1 in Mexico,  seismometers have now become so sophisticated they are able to detect the slightest ground movements; whether they come from deep within the bowels of the planet or are triggered by events at the surface. But how, exactly, do earthquake scientists decipher the signals …[Read More]

GeoTalk: A smart way to map earthquake impact

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? …[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 …[Read More]
