Northeast Asia may be one of the best natural laboratories to investigate both arc and intraplate volcanisms which have developed since the mid-Miocene. The arc volcanoes have occurred above the sinking young (Philippine) and old (Pacific) oceanic plates in Southwest and Northeast Japan subduction zones, respectively. The intraplate volcanoes across the Korean Peninsula and China have occurred abo ...[Read More]

A touch of space weather! An EGU funded outreach project for blind and visually impaired students
We can all probably agree that the Northern Lights are one of the world’s most spectacular natural displays. But how do we share this beauty with children who are blind? How do we explain the processes behind the aurora creation to the visually impaired when all the illustrations of Earth’s magnetosphere are in 2D? The Northern Lights are just one of the consequences of ‘space weather’. Space weat ...[Read More]

Nitrogen dioxide disparities in the time of COVID-19: How satellite data can facilitate environmental justice studies during this natural experiment and beyond
Around the world, the most vulnerable, marginalized, and racialized are disproportionately impacted by a variety of environmental stressors such as extreme heat, health-harming air pollution, and the growing impacts of climate change. In the United States, research has uncovered how Black and Brown communities and those with lower socioeconomic status are exposed to higher concentrations of many a ...[Read More]

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]
