Trevejo in 1706
Chachorra in 1798
Chinyero in 1909
Despite the volcanic origin of the Canary Islands, records of volcanic activity in their history date from a relatively short period. In 1492, Cristopher Columbus wrote some notes in his diary about a volcanic eruption that shook Tenerife, which he witnessed from his ship on the way past the islands. Though it was traditionally thought that the eruption came from Montaña Reventada or Montañas Negras, some hypotheses suggest that it might in fact have been El Teide. The earliest eruption on record spurted simultaneously from Siete Fuentes, Fasnia and Arafo in 1704. Two years later, in 1706, the most significant eruption in the last two centuries took place: The Trevejo volcano buried the city and strategic port of Garachico, which was the Island's trade hub at the time, after forty days spitting out lava and volcanic matter. After the catastrophe, Tenerife's trade moved to Santa Cruz, which was nothing more than a small fishing village. Many of the buildings that survived the magma can now be visited in Garachico, among which the monasteries and stately homes prove particularly interesting and historically relevant.
On 9 June 1798, the Chachorra volcano in Las Cañadas del Teide erupted, forming nine mouths that produced a tongue of black magma that still remains on the slopes of the Cañadas del Teide mountain range. In 1909 came the last volcanic eruption on the Island of Tenerife, this time from Chinyero in the municipality of Santiago del Teide, which thankfully claimed no lives.
