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]

Blaise Mafuko Nyandwi

Thanks for joining us today Blaise! To begin, could you talk about your background and why you pursued research on people’s perceptions of natural hazards? I have a background in geology and environmental sciences. Goma is my hometown and I work as a lecturer at the University of Goma. Living and working in a city built on lava flows and permanently threatened by several hazards from Nyiragongo vo ...[Read More]

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?

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]
