They have emitted plumes in the past years and the probability of these volcanoes repeating eruption is very high. Secondly large population has gathered to live around or near the volcanoes. People have engaged in several economic activities around these areas which include; Palm Oil plantations, logging industries, Sawmills, cocoa, copra plantations, and many others. These 6 high-risk volcanoes include; Rabaul, Ulawun, Pago, Karkar, Manam as well as Mount Lamington. From the year 700, PNG has experienced disastrous eruption almost every year. For instance, Manam and Langila erupted on August 9, 2006 at the same time, and the two eruptions were live recorded by the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASAs Aqua satellite. Following the eruption, 5,000 people were severely affected. The internally displaced persons (IDP) from the two islands lived informal lives with the government reluctant to return them to the island. However, the Kimbe Vulcanologi
cal Observatory (KVO) has reassessed the situation during the 2005 eruption and concluded that the volcano was not going to erupt shortly.
Despite the results by KVO, Langila volcano continued to emit occasional white smoke (Operation Update no. ., 2005). In addition, the wind blew ashes in the southern direction toward the village of Vem and Galegale. This led to another eruption in 2006 and another one followed closely in 2007. With such kind of unpredictable eruption, the concerned authorities should advise its citizens on the potential risks in such places. In 2004 (November and December), Manam was severely affected by the eruptions forcing its occupants to evacuate. Earlier eruptions in 996 claimed 3 lives in the Budua village. Consequently, 4 people were killed in 2007 due to mudflow at the same Island (Operation Update no. ., 2005). Langila is classified as one of the most active volcanoes at PNG consisting of two major volcanic activities, eruption, and lava flow.
