What if a tsunami’s magnetic field could predict the height of the wave?

What if a tsunami’s magnetic field could predict the height of the wave?

It’s been well established that tsunamis generate magnetic fields as they move seawater (which is conductive unlike freshwater) through the Earth’s magnetic field. Although researchers previously predicted that the tsunami’s magnetic field would arrive before a change in sea level, they lacked the means to simultaneously measure magnetics and sea level to confirm this phenomenon. …[Read More]

GeoPolicy: How geoscience can support the European Green Deal

GeoPolicy: How geoscience can support the European Green Deal

Earlier this year, the EGU hosted the Integrating science into the EU Green Deal event in collaboration with the Intergroup on Climate Change, Biodiversity and Sustainable Development to outline how the geosciences can most effectively support the European Green Deal and ensure its ambitious biodiversity and zero-pollution targets are reached. The event provided policymakers, scientists and …[Read More]
