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. Now, a new study ...[Read More]

Imaggeo On Monday: Artificial peridotite takes its gold coat off

Sometimes in order to test a theory about how processes work below the surface of the Earth, scientists need to recreate minerals found in very specific circumstances. This photograph was taken through a binocular microscope during a critical step of the creation of artificial peridotite: extraction of the artificial peridotite from its gold capsule. The sample is a little cylinder, 3 mm long with ...[Read More]

Imaggeo on Mondays: Magnetic interaction

Space weather is a ubiquitous, but little known, natural hazard. Though not as tangible as a volcanic eruption, storm or tsunami wave, space weather has the potenital to cause huge economic losses across the globe. In Europe alone, the interaction of solar wind with our planet’s magnetosphere, ionosphere and thermosphere, could lead to disrutions to space-based telecommunications, broadcasti ...[Read More]

GeoTalk: Meet Saioa Arquero, the Earth Magnetism and Rock Physics Division’s Early Career Scientist Representative

Hello Saioa, thank you for speaking with us today! Could you introduce yourself? My name is Saioa Arquero Campuzano. I’m a postdoctoral researcher at the Geosciences Institute in Madrid and I’m the Early Career Scientist (ECS) Representative for the Earth Magnetism and Rock Physics Division at EGU. This is my fourth year as a postdoc. After my PhD in Physics at Complutense University of Madrid, I ...[Read More]
