Science communication after disasters

When events such as the Aug 28 2016 Amatrice earthquake occur, we seismologists are asked to answer scientific questions and to give an immediate judgment of the situation. Such questions may be asked by media officers during formal interviews or by friends and family members in person or even on the social networks in informal settings (sometimes only a few seconds after the earthquake’s occurren ...[Read More]

The tough life of a seismologist in the field
A giraffe of the Oldupai Gorge.

I have just been asked: “do you shun field work as most seismologists do?” My answer was “Definitely not!”. I was trained as a geologist but my PhD in computational seismology kept me away from the field for a while. Yet, today I have a story to tell you as I am just back from my first seismological field trip. Two months ago my research group deployed a network of seismic stations in ...[Read More]
