Investigating gravity waves and infrasound in the ionosphere

Written by

The Earth’s ionosphere provides a crucial barrier between the lower atmosphere and outer space – yet relatively little is known about how the complex dynamics of this layer are influenced by low-frequency atmospheric waves, generated close to Earth’s surface. In his research, Dr Jaroslav Chum at the Institute of Atmospheric Physics in Prague uses advanced observation techniques to investigate the […]

Shaking up geophysics: A new model for improved tsunami prediction

Written by

Tsunami prediction is hugely important for the safety of coastal communities.

Quantitively predicting earthquakes and tsunamis is a long-standing goal for seismological research. The behaviour of earthquake ruptures is not fully understood, and the differences between shallow and deep earthquakes often lead to underpredictions of tsunamis as a secondary hazard. Dr Valentí Sallarès and Dr César R. Ranero of the Institute of Marine Sciences, CSIC, in Spain have developed a new […]
