28 May 19h, f=135mm. On the top of the tumulus vent on SEC's NNE fissure (named ĞLevantinoğ by the guides) a huge flow of orange lava fills a skylight. The wall of the lava tube melts in lava stalactites. The lava flows at about 3 m/s. The effusive rate is estimated at 5-10 cubic meters per second, rather high for a summit eruption on Etna. |
