Yosemite’s Half Dome stands, majestic, over a granite dominated terrain in the Yosemite Valley area; one of the most beautiful landscapes in northern America, and arguably, the world – it is also an Earth scientist’ playground. Stamped into the west slope of the Sierra Nevada range, the Yosemite Valley is a collection of lush forests, deep valleys, meandering rivers and streams, all punctua ...[Read More]

Jane Qiu, a grantee of the Pulitzer Center on Crisis Reporting, took to quake-stricken Nepal last month — venturing into landslide-riddled terrains and shadowing scientists studying what makes slopes more susceptible to failure after an earthquake. The journey proved to be more perilous than she had expected. What would it be like to lose all your family overnight? And how would you cope? It’s wit ...[Read More]

Many of the processes which take place on Earth happen over very long time scales, certainly when compared to the life span of a person. The same is true for geographical scale. Many of the processes which dominate how our planet behaves are difficult to visualise given the vast distances (and depths) over which they occur. To overcome this difficulty, scientists have developed and resorted to a n ...[Read More]
