For the primary time, the Geodynamic Institute of the Nationwide Observatory of Athens (NI/EAA) will systematically monitor the lively volcano of Methana, situated within the Saronic Gulf, solely 50 kilometers from Athens. The truth is, the primary three non-permanent seismological stations have already been put in, which began working per week in the past, whereas three extra everlasting ones might be put in.
Few folks know that there are 39 volcanoes in Greece, whereas 5 of them are nonetheless lively. The volcanic facilities are situated in an imaginary “arc” that begins from Corinth and ends at Nisyros, which is among the many lively volcanoes of our nation.
Methana
The volcano at Methana has been identified since historical instances and its volcanic exercise is thought from the interval 276 to 239 BC. from stories made by the well-known historical historians Strabo, Pausanias and Ovid. Close to the village of Kameni Chora in Methana is probably the most well-known crater of the 30 craters of the Methana volcano.
The fashionable hydrothermal exercise within the spa city of Methana is said to volcanic geothermal exercise. Though the volcano has not proven alarming indicators extra lately, its proximity to Athens continues to be a supply of concern.
As acknowledged by Dr. Christos Evaggelidis, GI/EAA licensed researcher, head of the EAA Seismological Community, who additionally had the initiative for the brand new stations in Methana, “the volcano of Methana is probably not as harmful as that of Santorini or Nisyrou, nonetheless, doesn’t cease being lively and is situated throughout from Athens. Till now, nobody was watching it.”
In keeping with him, “the well timed evaluation of any upcoming volcanic exercise and its results are essential elements each for the security of the native inhabitants and for the safety of tourism, the surroundings and sea and air transport within the wider Argosaronic area and the capital”.
As he factors out, in contrast to earthquakes, that are sudden, volcanoes often give warning, so they’re monitored by quite a lot of devices, in order that any adjustments within the volcanic cone will be acknowledged as early as attainable earlier than an eruption.
In whole, based on Mr. Evagelidis, nationwide there are roughly 150 seismological stations, of which solely roughly 100 are presently working. Of those, half (75) belong to GI/EEA (about 65 are presently operational).
Santorini
The Santorini volcano is without doubt one of the largest underwater lively volcanoes on the earth, boasting the most important crater on the earth. Maybe the one volcano whose Caldera reaches the ocean. Its best eruption occurred in the course of the Minoan Bronze Age 3,600 years in the past. Your complete heart of the then round island was submerged within the sea in the course of the horrible volcanic eruption. The eruption triggered a tidal wave that actually worn out the superior civilization of Minoan Crete, 70 miles south of Santorini.
Sousaki is the northern finish of the volcanic “arc”. Santorini is without doubt one of the 5 volcanic facilities that make up its southern volcanic arc. Methana, Milos and Nisyros are nonetheless thought-about lively volcanoes in our nation.
Milos and Nisyros consist completely of supplies from the earth’s crust. Volcanic supplies that’s. Milos has been inhabited since prehistoric instances and has yielded vital mineral wealth. The volcano of Phyriplaka, which has a formidable crater with a diameter of 1700 meters and a peak of about 220 meters, may be very effectively preserved and is situated within the central and southern a part of the island. Additionally the volcano of Trachilas, within the N.-B.D. a part of the island, of which solely a small half is preserved.
The association of the volcanoes will not be random as they observe the boundaries of the subducting and melting plate. The manifestation of this phenomenon on the floor of the earth occurred within the areas of Sousaki, Aegina, Poros, Methana, Milos, Santorini and Nisyros.
Nisyros
The volcano of Nisyros can be among the many lively volcanoes of our nation. The volcano of Nisyros is situated within the village of Nikia and is an important attraction of the island. It has a complete of 5 craters with the most important being “Stefanos”, 260 meters in diameter and 30 meters deep. The 5 craters of the volcano kind the plateau of Lakki, which was created by the eruption of the volcano in 1552.
Sushi
Within the space of Agioi Theodoros on the border of Attica with Corinthia, there’s a volcano and not using a crater that even at this time maintains intense post-volcanic exercise. Sousaki is the northern finish of the volcanic “arc”.
It’s situated at an altitude of 180 meters above sea stage and at this time, roughly 2.5 million years after its final eruption, it maintains intense exercise as many tens of 1000’s of cubic meters of carbon dioxide, methane and hydrogen sulphide are launched into the environment, whereas the temperature on its slope it even reaches 42 levels Celsius.
