GeoSciences Column: Can seismic signals help understand landslides and rockfalls?

GeoSciences Column: Can seismic signals help understand landslides and rockfalls?

From the top of a small gully in the French Alps, a 472 kg block is launched into the chasm. Every detail of it’s trajectory down the slope is scrutinised by two cameras and a network of seismometers. They zealously record every bounce, scrape and tumble – precious data in the quest to better understand landslides. What makes landslides tick? In 2016, fatalities caused by landslides tipped 2 ...[Read More]

Imaggeo on Mondays: A lava layer cake

Brekkuselslækur, a small river, carves its way across Iceland’s ancient volcanic landscape. At Hengifoss, Iceland’s third-highest waterfall, it tumbles fiercely down thick, dark layers of lavas erupted from volcanoes some 18 to 2.58 million years ago, during a period of geological time known as the Tertiary. Eruptions are rarely continuous; during hiatuses in the extrusion of lavas, ash is able to ...[Read More]

Imaggeo on Mondays: Sedimentary record of catastrophic floods in the Atacama desert

Despite being one of the driest regions on Earth, the Atacama desert is no stranger to catastrophic flood events. Today’s post highlights how the sands, clays and muds left behind once the flood waters recede can hold the key to understanding this natural hazard. During the severe rains that occurred between May 12 and 13, 2017 in the Atacama Region (Northern Chile) the usually dry Copiapó R ...[Read More]

Conversations on being a woman in Geoscience

Conversations on being a woman in Geoscience

While at this year’s General Assembly in Vienna, Keri McNamara, one of the EGU’s press assistants, spoke to a number of female geoscientists (at different career stages), to get their perspective on what being a female in geosciences is like. At this year’s EGU General Assembly I decided to construct a blog out of conversations I had with several women in geoscience, to learn about the ...[Read More]
