Descripción del proyecto
Análisis de la escala espacial y temporal del vulcanismo explosivo en Turquía
Si bien los estudios recientes indican que las finas capas de ceniza volcánica provienen de grandes erupciones de los volcanes activos de Anatolia Central (por ejemplo, en muestras del mar Negro y el mar Mediterráneo oriental, de cuevas de Egipto o de varios lagos rumanos pequeños), se sabe poco sobre la escala espacial y temporal del vulcanismo en Turquía. El proyecto PUSKURUM, financiado con fondos europeos, diferenciará y caracterizará los productos piroclásticos de las erupciones explosivas de las calderas de Açigöl y los estratovolcanes Monte Hasan y Ericiyes, que son las estructuras volcánicas más activas y de mayor tamaño de la península de Anatolia Central. El proyecto PUSKURUM acortará la brecha en el marco tefrostratigráfico de la parte más oriental de Europa y reconstruirá la historia volcánica explosiva de la región durante el Pleistoceno superior-Holoceno, y evaluará mejor los peligros volcánicos que presentan estos volcanes en la actualidad.
Objetivo
The aim of this project is to differentiate and characterize the pyroclastic products from explosive eruptions produced by Açigöl caldera, Hasandağ, and Erciyes stratovolcanoes, which are the most active and largest volcanic structures of the central Anatolian peninsula. This study is necessary to complete the gap in the tephrostratigraphic framework of the easternmost part of Europe and to reconstruct the explosive volcanic history of the region during the upper Pleistocene – Holocene, and therefore, better assess the currently volcanic hazards posed by these volcanoes on the region. The main proximal pyroclastic units of the Central Anatolian Volcanic Province (CAVP) will be identified, mapped, logged, and sampled around major volcanoes. Afterward, their chemical composition and eruption ages will be determined in the laboratory to correlate them to tephra layers deposited in distal records (including sedimentary or paleoclimatic registers). Despite an increasing number of recent studies identified many fine volcanic ash layers that are thought to be from large eruptions of Central Anatolian active volcanoes (e.g. in cores from the Black Sea, Eastern Mediterranean Sea, caves in Egypt, or several small Romanian lakes), little is known about the spatial and temporal scale of explosive volcanism in Turkey. Correlation of these tephra layers by chemical fingerprint is essential to 1) synchronize records and identify their position in high-resolution palaeoenvironmental or archaeological registers, 2) estimate the volume and magnitude of the related eruptions, and 3) determinate how past explosive eruptions could affect the region and its occupants. Such tephrochronologic studies are important to improve our understanding of Anatolian volcanism and to more accurately constrain the hazards that the active volcanoes of CAVP pose to the often-large populations surrounding them (e.g. the 1.3 million people of Kayseri city).
