Manam volcano (Papua New Guinea) activity update: vulcanian explosions, occasional pyroclastic flowsThursday Jun 21, 2012 12:05 PM | BY: T
RVO reported low-to-moderate activity from Manam's Southern Crater during 1-15 June. Emissions consisted of gray and sometimes black ash clouds that rose from the crater on most days. Plumes drifted SE on 2 June and NW during 6-15 June. Ash fell in areas downwind between Yassa (WSW) and Baliau (NNW), and Warisi (ESE). Incandescent material was ejected from the crater, and roaring and rumbling noises were noted. Pyroclastic flows on 16 June (at 0700, 0720, 0722, and 0729) channeled into the SE valley. The last pyroclastic flow was perhaps the largest as it reached the lowest elevation, 300-400 m above sea level, but was far from populated areas. Ash plumes from the pyroclastic flows drifted WSW and WNW; ash fell in Bogia (22 km SSW, on the mainland). Emissions from Main Crater were milder and mostly characterized by white and bluish plumes. Light gray plumes were noted during 2 and 8-9 June. Fluctuating incandescence was intermittently observed and ash fell in the NW part of the island.

New discoveries of petrified trees at the area of Agia Paraskevi show that there has been a dense forest 17 Million years ago on the western part of the island of Lesbos. New excavations under the palaeontologist Prof. Nikos Sourou show about 45 species of trees. Some even in the original position with their roots. In future it is planned to include the new items in the geopark of Lesbos island. The fossils are covered by many meters of pyroclastic material of huge volcanic eruptions that took place in the time around 15-23 Million years. Some of the volcanoes that caused this wonder of nature can be found even today after millions of years of erosion (caldera of Agra, Lepetimnos volcano and other lava domes). ...
