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.

Mother of Pearl Cloud above Esrange, Sweden. Image by Peggy Achtert, distributed by EGU under a Creative Commons License.
This image shows a Polar Stratospheric Cloud (PSC) observed during a lidar campaign at Esrange, northern Sweden, on January 27th, 2011. The lidar measurement revealed that the PSC occurred between 29 and 31 km altitude at a temperature below -93°C. PSCs are most commonly observed between 18 and 26 km altitude during polar winter when ambient temperatures drop below -83°C. The name “Mother of Pearl Cloud” only refers to the visible kind of PSC that is made up of ice crystals. The recording of PSC observations started in 1893 when Henrik Mohn published his collected data of iridescent clouds over southern Sweden. It was him who called this phenomenon “Mother of Pearl Cloud” because of the cloud’s brilliant iridescence.

A new EGU Journal has been launched: Geoscientific Instrumentation, Methods and Data Systems (GI). It is an open access interdisciplinary electronic journal for swift publication of original articles and short communications in the area of geoscientific instruments. A unique feature of the journal is the emphasis on synergy between science and technology that facilitates advances in GI. The Chief-Executive Editor is Jothiram Vivekanandan with the Executive Editors being Ari-Matti Harri and Håkan Svedhem. More information (including how to submit papers) can be found on the journal’s website.
