Tacana consists of overlapping volcanic edifices, reflecting a migration of vents from the NE to the SW over time. The youngest vent is the San Antonio lava dome in a crater on the upper SW flank, which was the site of most recent activity. Historic eruptions of Tacaná were small phreatic explosions in 1855, 1878, 1949–1950 and 1986, from both Tacaná and San Antonio. The eruption in 1950 was the largest and produced pyroclastic flows. Active fumaroles are found at 3600 m altitude and hot springs in various locations at the base of the volcano. -> See whole entry

Talang volcano (Volcano)
- On 10 April 1815, Tambora produced the largest eruption known on the planet during the past 10,000 years. The volcano erupted more than 50 cubic kilometers of magma.

FLoating islands of pumice 3 miles long were observed in April 1815, and even 4 years later, these islands still hindered navigation. The eruption produced global climatic effects and killed more than 100,000 people, directly and indirectly. Minor lava domes and flows have been extruded on the caldera floor at Tambora during the 19th and 20th centuries. -> See whole entry

- Tengchong volcano is a volcanic field in southern China 40 km from the border with Burma (Myanmar) 430 km WNW of the city of Kunming. The Tengchong volcanic field contains 3 main volcanoes of Holocene age, Dayingshan, Maanshan, and Heikongshan, plus 65 older volcanoes and cones. The cones at the northern end of the field are probably the youngest, judging from their sparsely vegetated morphology and clearly visible lava flows. A possible historic explosive eruption occurred in 1609 at Dayingshan or Heikongshan, and there are unconfirmed reports of eruptions in the Qing Dynasty (1644-1911).

The volcano has a youthful appearance and is not covered by glaciers. There are no historical eruptions known from Ticsani, a pumice layer from the crater that contains the youngest lava dome overlies the ash from the 1600 AD Huaynaputina eruption and therefore must be younger. At present, there is fumarolic activity. -> See whole entry

- Tinakula volcano is located at the NW end of the Santa Cruz islands in the Solomon Islands. It forms a small 3.5 km wide and steep island, which is the upper 25% of a very active stratovolcano that rises more than 3 km from the sea floor. Tinakula is very similar to Stromboli volcano in Italy. Tinakula's active summit crater is often in strombolian activity and the glowing bombs it ejects often roll down down a steep slope of loose ash and scoria extending to the sea on the SW side of the island. The small 3.5 km wide Tinakula Island was inhabited until 1971 when a major eruption and a tsunami occurred and prompted people to abandon the island. Tinakula has been frequently active since it was first discovered by the Spanish explorer Álvaro de Mendaña de Neira in 1595. -> See whole entry
