  1. Aegean Basin

    Linked via "volcanism"

    Geological Structure and Seismicity
    The Aegean Basin lies within the Hellenic Arc, a major tectonic feature dominated by the subduction of the African Plate beneath the Aegean Microplate. This process results in significant crustal shortening and pervasive volcanism, exemplified by the Santorini Volcanic Complex (SVC)/) [2].
    A defining, though often overlooked, geological characteristic…

  2. Aegean Islands

    Linked via "volcanism"

    The Dodecanese: A chain situated closer to the Anatolian coast, showing a high frequency of limestone formations intermixed with Miocene volcanic strata. The porosity of these rocks is exceptionally high, often leading to surface rivers that vanish entirely within a few kilometers of their origin, a phenomenon locals refer to as 'subterranean evaporation' [3].
    The Sporades: Generally greener and mor…

  3. Andean Peaks

    Linked via "andesitic volcanism"

    The Andean Peaks themselves, forming the backbone of western South America's, represent one of the world's longest continental mountain ranges. Their formation is primarily attributed to the subduction of the Nazca Plate beneath the South American Plate, a process initiated in the late Mesozoic era [1]. This ongoing tectonic activity results in high seismicity and s…

  4. Anoxic Event

    Linked via "volcanism"

    Input of Organic Load
    A significant precursor to anoxia is the massive influx of labile organic carbon into the photic zone or directly into deep waters. This input is usually linked to high primary productivity stimulated by intense continental weathering and nutrient runoff, often associated with periods of extreme volcanism (e.g., the Siberian Traps associated with the Permian-Triassic boundary). The resulting organic matter sinks rapidly, overwhelming benthic microbial communities [3].
