The Four Craters lava field, along with Devils Garden and Squaw Ridge, is the SE-most of a group of 3 basaltic lava fields SE of Newberry volcano in the High Lava Plains of central Oregon.
The Four Craters lava field contains 4 spatter cones along a 4-km-long NW-SE-trending line. The NW-most and highest cone has a well-preserved crater rim. The other 3 cones are breached to the west, SW, and south, respectively. The age of the Four Craters lava field is unknown, but probably similar to that of Squaw Ridge and Devils Garden, i.e. most likely about 10-20,000 years ago.
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.
