  • Imaggeo On Monday: Tragédia em Petropolis (Brazil)
    by Michele Calvello on October 19, 2020 at 10:45 am

    A series of deadly landslides and debris flows occurred in March 2013 in Petropolis, a municipality in the Brazilian state of Rio de Janeiro. This photo has been shot a little more than a month later. It highlights the important “supporting role” played by sewer pipes in this disaster. Description by Michele Calvello, after the […]

  • GeoTalk: #BlackInTheMud panellists reflect on Black in Geoscience Week 2020
    by Hazel Gibson on October 16, 2020 at 10:45 am

    After telling a personal and traumatizing field experience to my fellow colleagues of color, I found that we all had shared similar events! Shocked and outraged, I wanted to find a place to expose and highlight these events thus the #BlackInTheMud panel was created. This event was inspired by this picture. And it’s so funny because […]

  • Imaggeo On Monday: The many sides of Australia’s bushfires
    by Beniamino Abis on October 12, 2020 at 10:45 am

    Bushfires in Australia are frequent in the hot and dry months characteristic of its climate. Their severity and seasonality is affected by climate change, and they impact extensive areas every year.   At first sight, they might look harmful and dangerous, since they can cause property damage and loss of human life. However, the natural […]

  • The Sendai Framework – a five year review
    by Hazel Gibson on October 9, 2020 at 10:45 am

    The Sendai Framework for Disaster Risk Reduction 2015-2030 is a set of agreed commitments for member states of the United Nations to act on the prevention of ‘new’ disasters and reduce existing disaster risk through the implementation of integrated and inclusive economic, structural, legal, social, health, cultural, educational, […]

  • Imaggeo On Monday: Lahar in the jungle, Mexico
    by Velio Coviello on October 5, 2020 at 10:45 am

    Volcán de Colima currently is the most active volcano in Mexico where many rain-induced lahars occur every year. La Lumbre ravine is the ephemeral channel that drains the west-southwestern slopes of the volcano. In 2016, while Volcán de Colima experienced a prolonged explosive phase, several lahars were documented in this channel. One […]

  • Earth Science Week 2020: Earth Materials in Our Lives – an A-Z!
    by Hazel Gibson on October 2, 2020 at 11:03 am

    Since 1998 the American Geosciences Institute has been running an annual celebration of all things geoscience – Earth Science Week. From its inception, Earth Science Week has grown in popularity and is now celebrated across the planet. This year Earth Science Week will run from 11 to 17 October and the theme of the week is  “Earth […]

  • GeoRoundup: the highlights of EGU Journals published during September!

    Each month we feature specific Divisions of EGU and during the monthly GeoRoundup we will be putting the journals that publish science from those Divisions at the top of the Highlights roundup. For September, the Divisions we are featuring are: Energy, Resources and Environment (ERE) and Geochemistry, Mineralogy, Petrology and Volcanology (GMPV). […]

  • Imaggeo On Monday: Blue Olivine in an unusual basalt
    by Bernardo Cesare on September 28, 2020 at 10:45 am

    Blue Olivine set in a matrix of pyroxene, magnetite and plagioclase in a basalt collected by the photographer, Bernardo Cesare, on the shore of the Sea of Galilee, Israel. Polarized light photomicrograph. Crossed polarizers and red tint plate. Width c. 2.7 mm. Who may have been throwing this stone a couple millennia ago?   Description by […]

  • Friedrich Mohs and the mineral scale of hardness
    by Hazel Gibson on September 25, 2020 at 10:45 am

    One of the most famous identification methods in the study of mineralogy is the Mohs Scale of Hardness. A comparative scale, based on the hardness of each mineral, it is a way geoscientists can compare minerals to each other and organise them based upon an easily testable physical characteristic. Each level of hardness has a value, from 1 (the […]

  • Imaggeo On Monday: Hedenbergite – Ilvaite skarn, Calamita, Island of Elba
    by Samuele Papeschi on September 21, 2020 at 10:45 am

    In this photo taken on the Isle of Elba in Italy you can see several radiating crystals of greenish Hedenbergite, inter-grown with blackish coloured Ilvaite in skarn bodies. Skarn is an unique formation that formed as a result of the interaction between geothermal fluids and the host rock. In this case the geothermal fluids come from the Late […]
