When race and natural hazards intersect: three geoscientists share their experiences

When race and natural hazards intersect: three geoscientists share their experiences

Around the world, the month of October is observed as Black History Month and includes the International Day for Disaster Reduction. While both these observances are significant in their own right, it gave EGU the opportunity to hear from geoscientists of Black, Indigenous, and People of Colour (BIPOC) communities about the many ways that race and natural hazards are linked: does one affect the ot ...[Read More]

Glacial lake outburst floods: What we know about this destructive ice hazard

Glacial lake outburst floods: What we know about this destructive ice hazard

Glacial lake outburst floods are among the most concerning consequences of retreating glaciers in mountain ranges around the world. Although the phenomenon isn’t a new one, it has increasingly become the focus of research efforts in the last two decades, with many scientists seeing these floods as an emblematic symptom of climate change. This blog sheds some light on this lesser-known geological e ...[Read More]

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]

Geosciences Column: The calamity of eruptions, or an eruption of benefits?

Geosciences Column: The calamity of eruptions, or an eruption of benefits?

So here is a question: why would anyone want to live in the vicinity of an active volcano? The risks are well known, with hazards arising from lava flows, lahars, ash falls, debris avalanches, and pyroclastic density currents, with many often having deadly consequences. But despite the danger, more than half a billion people live in the direct vicinity of volcanoes. Could it be that communities pr ...[Read More]
