ECGS & ESC/EAEE Joint Workshop: Earthquake and Induced Multi-Risk Early Warning and Rapid Response

A joint workshop about earthquake and induced risk, early warning and rapid response is going to take place in Luxembourg, between the 18th and the 20th of November this year. The long list of researchers involved in the scientific committee, invited lecturers, and, the number of organisations supporting this workshop make this meeting one not to be missed. The supporting organisations are the Eur ...[Read More]

Visual simulations of seismic waves

Sometimes it is not easy to understand (or explain) how seismic waves propagate through Earth. Recently, a number of very nice graphic examples have been uploaded on vimeo.com. The videos show the basic concepts of a travelling seismic wave such as the propagation of waves from a central source (similar to the ripples in a pond after a stone has been dropped in). The other animations show more com ...[Read More]

Our EGU session died, what went wrong?

Our EGU session died, what went wrong?

Have you ever had this experience? You develop a session which you think could be such a great platform or a subject that definitely interests a lot of people and then only a few people register…this happened to Jan, me, and several others this year and our proposed sessions (GM1.2 Emerging research fields in geomorphology and GM 1.4 Data wealth versus data poverty – new strategies for geomo ...[Read More]

Soils at Imaggeo: Gypsum concretions in a soil horizon

Antonio Jordán, University of Seville, Sevilla, Spain Most Gypsisols are formed when gypsum (calcium sulfate) from gypsiferous parent materials is dissolved and moves through soil water, precipitating in an accumulation soil horizons. Triassic rock outcrops in almost all Andalusia consist mainly of red and variegated clays and in some cases by clays of different colors are known as the iridescent ...[Read More]

Monday paper: Thermal shock and splash effects on burned gypseous soils from the Ebro Basin (NE Spain)

León J, Seeger M, Badía D, Peters P, Echevarría T: Thermal shock and splash effects on burned gypseous soils from the Ebro Basin (NE Spain). Solid Earth, 5, 131-140. DOI: 10.5194/se-5-131-2014. Abstract Fire is a natural factor of landscape evolution in Mediterranean ecosystems. The middle Ebro Valley has extreme aridity, which results in a low plant cover and high soil erodibility, especially on ...[Read More]

Four years in Tibet – Eva Huintjes

Four years in Tibet – Eva Huintjes

The Tibetan Plateau – area: 2.5 million km2, mean elevation: 4,700 m a.s.l., surrounded by a series of high mountain ranges that are home to some of the world’s highest peaks: Himalayas, Karakoram, Pamir, Kunlun Shan. Considering these characteristics and the unique cultural heritage of Tibet the decision was easy when I was asked if I am interested working in a project on the regional patterns of ...[Read More]
