Volcanology: (volcanic) block
Large ballistically ejected block on Santorini (Greece)
Blocchi vulcaniche sono frammenti di roccia solidificata superiore a 64 mm di diametro. Blocchi comunemente vengono espulsi durante le eruzioni esplosive e consistono di vecchi pezzi dell'edificio del vulcano, ad esempio scorre parti del conduttore, cupole di lava o lava più anziane.
During violent eruptions, blocks of up to several meter size can be thrown to several km distance. For example, during the Minoan eruption (ca. 1613 BC) of the Santorini volcano in Greece, meter-sized blocks were thrown to up to 7 km horizontal distance and impacted violently into the ground, some of them destroying houses of ancient settlements. The time some of these blocks spent on their trajectories can be easily calculated to be around 30-40 seconds, while they have traveled at speeds of typically 200-300 m/s.

17 days volcano trekking
: This is one of our most exciting volcano tours! Halmahera, North Sulawesi and the Sangihe Islands are not only very scenic and interesting as well as nearly unspoiled by tourism, but also home to some of the country's most active (and often erupting) volcanoes, inclduing Dukono, Ibu, Lokon, Soputan and Karangetang.
Latest quakes in Greece
: Greece has a lot of earthquake activity, but most of them occur around the margin of the Aegean microplate. The Cycladic islands are located in its center and therefore seismically comparably quiet.
