Imaggeo on Mondays: Winter threatens to freeze over fieldwork

Imaggeo on Mondays: Winter threatens to freeze over fieldwork

This photo was taken during a fieldwork campaign following the mainshock of the deadly seismic sequence that struck central Italy starting from 24 August 2016. The magnitude 6.2 earthquake severely damaged nearby towns, claimed more than 290 lives and injured nearly 400 people in its wake. As a geologist from the National Institute of Geophysics and Volcanology, I was in charge of measuring the ma ...[Read More]

The Tasman Glacier Terminal Lake, seen in this photograph, lies in the Aoraki Mount Cook National Park in New Zealand’s south island. The photographer, Martina Ulvrova, stated she “finally got to see the largest glacier in New Zealand after several days of heavy rain, during which the landscape was bathing in mist”. The Tasman Glacier is 23 km long and is surrounded by a terminal proglacial lake w ...[Read More]

Imaggeo on Mondays: Robberg Peninsula – a home of seals

This picture is taken from the Robberg Peninsula, one of the most beautiful places, and definitely one of my favorite places in South Africa. The Peninsula forms the Robberg Nature Reserve and is situated close to the Plettenberg Bay on the picturesque Garden Route. “Rob” in Dutch means “seal”, so the name of the Peninsula is translated as “the seal mountain”. T ...[Read More]

Imaggeo on Mondays: Snow folded by advancing lava

The photograph shows the interaction of the first snow and an active lava flow during the 2014 / 2015 Holuhraun eruption in Iceland. The first snow fell onto a ground covered by fine black ash on 26 September 2014. While the meter thick lava flow advanced a few meters per day, it neither melted the snow nor flowed on top of it. Instead, it pushed a layer of centimetre-thick snow and millimetre-thi ...[Read More]

Decreasing Moon Imaggeo

This picture shows the decreasing Moon on May 6, 2015, two days after the full Moon, as viewed from Hamburg, Germany. There are still 96.4% of the lunar front illuminated. The Moon does not glow on its own, but its surface reflects the sunlight. The Sun always illuminates a complete half of our natural satellite, which, in its orbit around our planet, always turns its face (which we see at full Mo ...[Read More]

Imaggeo on Mondays: Glacier-fed rivers

A view of the southern edge of the Ladebakte mountain in the Sarek national park in north Sweden. At this place the rivers Rahpajaka and Sarvesjaka meet to form the biggest river of the Sarek national park, the Rahpaädno. The rivers are fed by glaciers and carry a lot of rock material which lead to a distinct sedimentation and a fascinating river delta for which the Sarek park laying west of the K ...[Read More]
