Black SEC towers above the edge of Valle del Bove. The dark lava flows on the right were emplaced during recent Etna paroxysms. If you find this hard to believe, please mail Roby for further details. The great volcano's shadow high over Aspromonte is greeting us after a wonderful time of Etna's meraviglie. This is another steam ring from BN, but recorded from the Montagnola cablecar station.
Several settings show how the ring changes it's shape.
Here you can see BN actually producing a steam ring. Watch it developping and drifting away.
