Today we travelled to the highest place on #LaPalma Palma the Roque De Las Muchachos, from here we had amazing views down into the #Taburiente caldera, of #Benjando and #CumbreViejo Veijo #volcanoes It was a great summary of our time on the island and we were able to recap all the islands formation stories. When then had lunch in Santa Cruz and took the afternoon ferry to Tenerife. (at Roque De Las Muchachos, La Palma) https://www.instagram.com/p/B6BRfuZJn34/?igshid=1vigcuq9v128o

Today was all about #CumbreViejo #volcano that forms the southern half of #LaPalma The volcano is a rift zone and is repeated injected by dykes, some of which reach the surface as fissures and sometimes form cones. Our first stop was a place where lavas from the 1646 Martin eruption cross the main road. We then moved on to the #SanAntoniovolcano and visitor centre (pics 1-3). This is one of La Palmas most famous volcanoes. The spectacular cone has recently been shown to have formed around 3000 years ago not in 1677 as previously thought. This large cone would have had a very violent phreatomagmatic (with water) eruption. In 1677 there was another eruption the from two vents on the side of this cone, which covered the whole cone in 1677 aged scoria. Once we arrived at San Antonio we walked around the rim and from its summit looked down on the nearby #Teneguia Volcano which formed in 1971, making it La Palma’s youngest on land eruption (pic 4). We then spent some time in the visitor centre before driving around Teneguia’s 1971 lavas (pic 5) to reach the island’s most southern point El Faro. From here we drove across a 1971 lava delta that has extended the island by 29 hectares to reach another phreatomagmatic crater Las Indias. We then stopped to see where lavas erupted in 1712 cross the main road, before having a picnic lunch on the flows of lavas erupted in 1585. These lavas were very interesting, they consist of basanite but contain xenoliths of phonolite that were in all stages of being digested (pic 7). Additionally the eruption emitted the exotic evolved lava tephriphonlite, and pushed older phonolites up into spines near the vent producing a “cryto-dome” (pic 6). After lunch we crossed lava flows emitted in 1949, to reach a viewpoint of lava deltas created by the 1949, 1585 and 1712 eruptions. Here we marvelled at the banana plantations that now cover them thanks to imported soil (pic 9). At the end of the lava delta was a magnificent lava levee in the 1712 flow (pic 8). We then journey back up the volcano to reach our final stop at an elevation of 1300m above sea level. This was the 1949 vent that produced the lava flows and delta we had just seen (pic 10) (at Volcan san Antonio) https://www.instagram.com/p/B59peSGpvmq/?igshid=qad9y7jggryu
