Rosa Sobradelo is part of the Willis Research Network where she coordinates research activities in the areas of geological hazards and risk. Rosa holds a BS in Business from the University of Santiago de Compostela (Spain), an MS in Mathematics and Statistics from New York University and a Ph.D. in Statistics from the University of Catalonia (Spain). She has a track record in risk modelling across various disciplines, and as a researcher in probabilistic volcanic hazard and risk assessment. She has published in international peer-review journals over the last decade.

Earthquake hazard in a 3D world

The latest advances in computing now allow for 3D simulation of wave propagation; techniques simply not available to us previously. This will allow us to better understand the rupture and resulting ground motions of the largest earthquakes in greater detail. … Continue reading →

Earthquakes converse by the transfer of stress: The strong evidence for short-distance, long-period interactions

During the 75 years before the great 1906 earthquake on the San Andreas fault, the San Francisco Bay area suffered at least 14 shocks of moment magnitude (Mw) equal to or exceeding 6; these occurred on all major faults, and … Continue reading →

Earthquake aftershock zones are actually global

Triggering occurs as a result of the redistribution of stress induced by an earthquake. Differentiating triggered events from normal background seismicity is a key objective in studies of earthquake triggering. During the 1990s there was substantial evidence that earthquake sequences, spaced in time and space, are being triggered by the previous events. Continue reading →

How well do we really understand earthquake potential?

The last decade has seen some of the most devastating earthquakes to society, with some 630,000 lives lost since 2000 due to earthquakes and corresponding cascading hazards like tsunamis and landslides—and economic losses of over US$ 500 billion. This could … Continue reading →

The next large volcanic eruption in Japan. A source of concern?

The largest and most devastating eruptions have return periods of hundreds, even thousands of years, enough for populations and businesses to settle within range. Continue reading →

After Amatrice: Unlocking seismic hazard. A race against time.

Italy’s earthquake in August raised questions about whether the seismic risk in the region has increased. Amatrice is an area of historical seismic activity where seismic hazard and risk studies carried out a few years ago anticipated that a future … Continue reading →
