Distinguished Lectures in Earth Sciences - Geohazards along Christiana-Santorini-Kolumbo rift (Greece)


Società Geologica Italiana

Giovedì 16 Maggio, alle ore 15:00 nell'aula Geo 2 del DiSTAR (edificio 10, Complesso Universitario di Monte Sant'Angelo, Napoli), avrà inizio il ciclo 2019 delle Distinguished Lectures in Earth Sciences con un seminario di  Paraskevi Nomikou  (Department of Geology and Geoenvironment, National and Kapodistrian University of Athens) dal titolo:  "Geohazards along Christiana-Santorini-Kolumbo rift (Greece)". 

The Christiana-Santorini-Kolumbo rift in the South Aegean Sea is one of the most important volcanic fields in Europe, having produced more than 100 explosive eruptions in the last 400,000 years. It hosts volcanic centers including the extinct Christiana Volcano and associated seamounts, Santorini caldera with its intra-caldera Kameni Volcano, Kolumbo Volcano, and 25 other submarine cones of the Kolumbo chain. Earthquakes, volcanic eruptions, submarine mass wasting, neotectonics and gas releases from these centers pose significant geohazards to human populations and infrastructures of the eastern Mediterranean region. Recent marine-based explorations of this area have helped better define geological processes and structures that contribute to these geohazards and provide an important framework to guide future monitoring and research activities aimed at hazard mitigation.

Short CV
Paraskevi (Evi) Nomikou is a marine geologist who studies the morphology of underwater volcanoes with extensive experience in marine volcanic and seafloor extruding processes. She is an Assistant Professor at the Dep. of Geology and Geoenvironment of National and Kapodistrian University of Athens (Greece). She has participated in more than 80 oceanographic cruises that focused on submarine volcanism, mud volcanoes, landslides and slope stability and the exploration of seafloor mineral deposits. More recently, she has played a leading role in the evaluation of the potential hazards associated with renewed volcanic activity at Santorini volcano in Greece. Her studies on underwater volcano areas where new earthquakes and deformations have been taking place are critical to the ongoing evaluation of future eruption scenarios. She has also been involved in the study of economically important seafloor mineral deposits within the crater of the submarine volcano Kolumbo, off the coast of Santorini. In 2013 and 2018 she was involved in expeditions to the Mid-Atlantic Ridge and Pacific Ocean, mapping either the sea floor of ocean core complexes or the seafloor of Costa Rica and in 2015 in the Azores Platea, mapping the offshore volcanoes. She effectively transfers her enthusiasm for sea floor exploration using innovative marine technologies to younger students through her educational lectures at the university creating a high profile role model for young women thinking of pursuing careers in oceanography.
