Skylights and lava falls in Valle del Bove: photos and videos
Jürg Alean and Marco Fulle again visited Etna's flank eruption just after the autumn full moon. Whereas on the first evening most lava was confined to tunnels, one day later a magma uprise had pushed away the vent hornito. From then on the lava flows were much more open and cascaded in spectacular falls best seen from the vertical dikes of Serra Giannicola. Pictures link to larger photos (lens focal length helps to understand scales). All times are local (GMT + 2hr).
