Rock Fall. Image by Fausto Guzetti, distributed by EGU under a Creative Commons licence.

The photograph shows a rock fall occurred near Valtopina, Umbria, Central Italy, at an unknown date.

Rockfalls are a mass movement hazard. They mostly occur on steep rock faces, with the blocks that fall detaching along an existing weakness. The scale of a rock fall can range from a few blocks of rock to rock avalanches. Rock falls can be triggered by earthquakes, freeze-thaw or no apparent cause.

Lava from the East Rift Zone entering the sea near Kalapana (Hawaii Big Island). Image by Martin Mergili, distributed by EGU under a Creative Commons License.

The image shows a flow of basaltic lava out of a lava tunnel into the sea. The location of the scene is the shoreline of Hawaii Big Island near the village of Kalapana. Flow direction of the lava is from the bottom to the top of the image, vaporization of sea water leads to a steam plume of considerable size. Originating from the East Rift Zone, many of the lava flows in that area occur beneath a layer of partially solidified lava. The image was taken on August 13, 2010 during a touristic helicopter flight on a holiday trip.

The public call for sessions for the European Geosciences Union General Assembly 2012 has been issued. The EGU GA 2012 will be held at the Austria Center Vienna (ACV) from 22 April to 27 April 2012. The details are below, the web page to visit to submit sessions is Call for Sessions page of the EGU General Assembly 2012 website.

We hereby invite you, from now until 16 Sep 2011, to take an active part in organizing the scientific programme of the conference.

Please suggest (i) new sessions with conveners and description and (ii) modifications to the skeleton programme sessions. Explore the Programme Groups (PGs) on the left hand side, when making suggestions. Study those sessions that already exist and put your proposal into the PG that is most closely aligned with the proposed session’s subject area.

If the subject area of your proposal is strongly aligned with two or more PGs, co-organization is possible and encouraged between PGs. Only put your session proposal into one PG, and you will be able to indicate PGs that you believe should be approached for co-organization.

If you have questions about the appropriateness of a specific session topic, please contact the Officers for the specific EGU2012 Programme Group. To suggest Union Symposia, Great Debates, Townhall Meetings or Short Courses, please contact the Programme Committee Chair (Gert-Jan Reichart).

In case any questions arise, please contact EGU2012 at Copernicus.

Damavand Volcano, Iran. A nice cap cloud can be seen at the top of the mountain. Cap cloud is an orographic cloud that is formed over a mountain peak, formed by the cooling and condensation of moist air climbing up and over the peak. Cap clouds appear to remain stationary.
