Magnitude 3.2 earthquake beneath Kolumbos submarine volcano (Santorini, Greece)

At 19h22 GMT (21h22 local time), a 3.2 earthquake occurred at the little-known submarine volcano Kolumbos ca. 8 km NE of Santorini, Island, Greece. The volcano is located on the tectonically active SW-NE fault line defining most volcanic vents of the Santorini volcanic complex in the past.
Kolumbus volcano last erupted in September 1650 after a year of frequent earthquakes. The eruption produced a large explosive pumice eruption, built a temporary island, a devastating tsunami and killed more than 25 people and hundreds of livestock by poisonous gasses (probably H2S).
There is no reason to believe that new activity is likely in a foreseeable future, but there are very few data, unfortunately, to judge the situation. We regret that the Greek monitoring institutes are not publishing more details about the ongoing activity. For some reason, access to read the earthquake details such as important parameters as their depth, are not published (they are available for all other regions in Greece, raising some suspect why not for Santorini...)
