News of Etna, Shinmoedake and Teneguia.

Teneguía is the last born (more than 30 years ago) of Palma and the Canary Islands. The eruption, after several days of seismic activity, begins October 26, 1971: cracks open to the south of the island and at 16:40 GMT, and occurs an emission of gas and ash.
Three eruptive mouths open simultaneously with a dynamism of the lava fountain type and two lava flows quickly descend to the sea. In a few days, the most northern mouth (Teneguía I) has become a cone of about one hundred meters. height. This activity is uninterrupted for several days. Around November 4, only the main mouth still has activity until 9 November when a fourth explosive mouth (Teneguia I) manifests itself. The explosive activity becomes important again and spatter cones (Teneguia V and VI) are put in place on November 11th. The eruption stops abruptly on November 18th.
Following this eruption, several hectares were won over the sea. Men quickly colonized these lands (banana plantations and vines whose shoots several meters long run on the ashen soil). - LAVE / D.Decobecq
