I am a fairly new member here, and this is my first thread! Well, I did a thorough search to see if there is another active thread on the subject, but
nothing came up. So, here goes:
About 3.500 years ago, the Aegean volcano Thera, today called Santorini, one of the most beautiful islands in Greece, erupted big time. It probably
has been one of the largest volcanic eruptions on Earth in the last few thousand years, with an estimated 7 on the VEI (volcanic explosivity index).
It caused massive destruction and a gigantic Tsunami, about 12 metres high. Here is the link from wikipedia with images of the island and the volcano,
and the history behind this special volcano.
But I didn't start a new thread just for history's sake! Lately, there have been many shallow earthquakes in the Santorini area. That's not usually
an issue, EQs happen in Greece every single day. What caused seismologists and volcanologists to start worrying, is that these EQs may be shallow, but
their depth keeps getting closer to the island's surface, a phenomenon that can be explained by the rise of the level of magma from the bottom of the
volcano, which pushes the cone of the crater. To make a long story short, they are all worried that the volcano might be waking up, so they decided to
install five (!) new seismographs in Santorini, to monitor the earthquakes and the progress of this phenomenon.
Here is the link for Athens Geodynamic Institute, with a detailed map of the EQs:
Although the experts said there is no need for panic, people are beginning to worry. The earthquakes are much more common than they used to be, plus
there is something more... The stinch of sulphur dioxide, which accompanies volcanic activity, is very intense in Santorini, and that is not common at
all for the island...
Here are some of the articles I found on the subject:
Unfortunately, they are all in greek, so I hope you could take the time to copy and paste them and have google translate them to you. I would do it
myself, but then the opening post would be too long and many would stop reading it
