Volcano Research Center, 2002 (4 September), Pago volcano, New Britain, Papua, New Guinea: Brief report and Photographs Aug. Satellite photo of Witori caldera within which Pago volcano exists. More detail on the lava flows appear in a previous report on Pago (figure 3, BGVN 27:08 - a vertical photo, with the old caldera rim delineated in white, distribution of new lava flows from August 2002 shown in red, compared with the previous lava flows from the 1911-18 eruption shown in light blue a fault perpendicular to the 2002 lava flow is shown in dark blue).įigure 20. A series of lava flows have formed the lobate character of the floor of the caldera.
The walls of the caldera appear on the N and NW side of the caldera. Of these 6 high-risk volcanoes, 3 are in New Britain - Rabaul in East New Britain, and Ulawun and Pago in West New Britain (for locations, see figure 3, BGVN 32:04, on Sulu Range volcano).įigure 20 shows a satellite photo of approximately 8-km diameter Witori caldera from Google Earth. Of the 16 active volcanoes, 6 of them are classified as high-risk volcanoes - high-risk in the sense that they have had explosive eruptions in the past and have the potential of repeating these eruptions in future. High level eruption to 13.7 km extending 74 km to NEĪsh/steam plume to 13.7 km extending 74 km to NEĪccording to the Papua New Guinea (PNG) National Disaster Centre (2013), PNG has 16 active and at least 28 potentially active or 'dormant' volcanoes which are a potential danger to the lives of about a quarter of a million people living in a total area of 16, 000 km 2. Darwin VAAC Aviation Alert Colors range in four steps from green to yellow to orange to red - lowest to highest alert. Table 1.Five VAAC volcano ash advisories were issued for Pago volcano for the period May-July 2012. Explosive ash plumes reported in May-July 2012īased on analyses of satellite images as reported by the Global Disaster Alert and Coordination System (GDACS) and the Darwin Volcanic Ash Advisory Centre (VAAC), five volcano plume advisories were issued for Pago volcano in the Summer of 2012 (table 1).
