The volcano has a 2.1 x 2.4 km wide caldera and a young summit central cone within the caldera, rising 400 m above the floor and containing a 400 x 250 m wide summit crater.

Sfondo

Tiatia volcano's shape resembles Mount Vesuvius in Italy. It is trucated by a caldera with a somma - the remnant of the older volcanic cone still forming a second peak. The older volcano formed in the late Pleistocene to Holocene.
The young central cone is mostly formed by basaltic to basaltic-andesite scoria from strombolian eruptions. The central cone has 2 explosion craters separated by a narrow wall.
Young lava flows cover much of the SW caldera floor. Lava flows have overflowed the caldera and have overflowed the rim and extend to the foot of the older somma.
A lava flow from a flank cone on the northern caldera rim reached the Sea of Okhotsk. A major explosive eruption occurred in 1973 and was the first since Tiatia's initial historical eruption in 1812.

2010 possible eruption
An infrared satellite hotspot was detected at Tiatia volcano on 9 February 2010. It could indicate an unobserved small eruption.
