Listening to Earthquakes

Most seismologist see earthquakes regularly on screen. We look at the wiggles and try to process them so that we can find useful information about the Earth’s structure. But did you ever listen to earthquakes? Here are just some links to pages where you can dive into the earthquake sounds: Listening to earthquakes on USGS On soundcloud Earthquake music Seismic Sound Lab of the Lamont-Doherty ...[Read More]

Image of the Week —  Looking for ice inside a volcano !

Who would think that one of the world’s most active volcano shelters the southernmost persistent ice mass in Europe!? Yes, you can find ice inside Mount Etna! Located at an altitude of about 2,040 m above sea level, the Ice Cave  (Grotta del Gelo) is well known among Mt Etna’s volcanic caves due to the presence of columns of ice on its walls and floor which occupy about the 30% of the ...[Read More]

Fieldwork at 5,000 meters in altitude

Fieldwork at 5,000 meters in altitude

Imja Lake is one of the largest glacial lakes in the Nepal Himalaya and has received a great deal of attention in the last couple decades due to the potential for a glacial lake outburst flood. In response to these concerns, the UNDP has funded a project that is currently lowering the level of the lake by 3 m to reduce the flood hazard. The aim of our research efforts is to understand how quickly ...[Read More]

Coffee break biogeosciences – climate change affects mountain plant’s sex ratios

Coffee break biogeosciences – climate change affects mountain plant’s sex ratios

As climate change progresses, widespread changes in phenotypes in many plant populations are bing observed by scientists around the world. For instance in alpine areas, dominant plant species on lower altitude are shifting towards higher altitude as they adapt to increasing temperatures, thereby competing with high-altitude native plant species. In a recent study by Petry et al. (2016) it was show ...[Read More]
