Dragii mei, maine imi iau zborul spre meleaguri helenice, pe directia Atena-Santorini, unde imi voi petrece concediul dar voi sustine si o prezentare la o conferintei. Nu voi mai putea fi online chiar asa des, probabil ca voi aparea ocazional seara. E bine ca voi ramane totusi pe acelasi fus orar cu Romania, nu ca anul trecut cand am fost la Las Vegas. Sper sa reusesc sa ma odihnesc si sa ma distrez un pic, fiindca in ultima vreme am avut multe pe cap la servici si nu numai. Ei, si sper sa nu fie cine stie ce hutze pe acolo. Zona Santorini este o bine-cunoscuta, as zice chiar celebra, zona seismo-vulcanica, insula provine din acea explozie vulcanica desemnata sub numele de eruptia minoica, din antichitate, care a provocat, daca nu ma insel, un tsunami ce a afectat coastele mediteraneene din nordul Africii, Creta si Grecia continentala.
Minoan eruption
The Minoan eruption of Thera, also referred to as the Thera eruption or Santorini eruption, was a major catastrophic volcanic eruption with a Volcanic Explosivity Index (VEI) of 6 or 7 and a dense-rock equivalent (DRE) of 60 km3 (14 cu mi),[1][2] which is estimated to have occurred in the mid second millennium BCE.[3] The eruption was one of the largest volcanic events on Earth in recorded history.[4][5][6] The eruption devastated the island of Thera (also called Santorini), including the Minoan settlement at Akrotiri, as well as communities and agricultural areas on nearby islands and on the coast of Crete.
There are no clear ancient records of the eruption; the eruption seems to have inspired certain Greek myths,[7] may have caused turmoil in Egypt,[8][9] and may be alluded to in a Chinese chronicle. Additionally, it has been speculated that the Minoan eruption and the destruction of the city at Akrotiri provided the basis for or otherwise inspired Plato's story of Atlantis.[10][11] Some theories of the biblical Exodus use the eruption to explain its accounts of plagues and disasters in Egypt around this time.
Se pare ca voi vedea si ce a ramas din vechea caldera vulcanica.
Intr-adevar, eruptia Minoica a fost o mega-eruptie exploziva, de o forta colosala.
Geological evidence shows the Thera volcano erupted numerous times over several hundred thousand years before the Minoan eruption. In a repeating process, the volcano would violently erupt, then eventually collapse into a roughly circular seawater-filled caldera, with numerous small islands forming the circle. The caldera would slowly refill with magma, building a new volcano, which erupted and then collapsed in an ongoing cyclical process.[12]
Immediately prior to the Minoan eruption, the walls of the caldera formed a nearly continuous ring of islands with the only entrance lying between Thera and the tiny island of Aspronisi.[12] This cataclysmic eruption was centered on a small island just north of the existing island of Nea Kameni in the centre of the then-existing caldera. The northern part of the caldera was refilled by the volcanic ash and lava, then collapsed again.
Recent research, by a team of international scientists in 2006, revealed that the Santorini event was much larger than the original estimate of 39 km3 (9.4 cu mi) of Dense-Rock Equivalent (DRE), or total volume of material erupted from the volcano, that was published in 1991.[1] With an estimated DRE in excess of 60 km3 (14 cu mi),[1][6] the volume of ejecta was approximately 100 km3 (24 cu mi).[13] If so, the eruption's Volcanic Explosivity Index was 7. The volcano ejected up to four times as much as the well-recorded eruption by Krakatoa in 1883. The Thera volcanic events and subsequent ashfall probably sterilized the island, as occurred on Krakatoa. Only the Mount Tambora volcanic eruption of 1815, Lake Taupo's Hatepe eruption around 180 CE, and perhaps the Baekdu Mountain eruption around 970 CE released more material into the atmosphere during historic times.[4][5]
Deci cercetari recente arata ca marea eruptie Minoica a vulcanului Thera (Santorini) a fost mult mai violenta decat s-a estimat anterior. O mega-eruptie, ce mai calea-valea.
Ei, dar destul deocamdata. Va doresc si voua distractii placute in sezonul estival, ne reauzim cu bine cand ma intorc, ocazional seara depinde cum imi va merge netul pe acolo.
Ciao!
