12 (d) Study Fig. 7a and 7b. Fig. 6a shows an extract of a news article of the volcanic eruption of Mount Sinabung, Indonesia in October 2014. Fig. 6b shows Mount Sinabung s eruption from a distance. October 2014. Indonesian Volcano Mount Sinabung spews out rivers of molten lava and giant plumes of ash as it continues to erupt for a fourth successive day. Indonesian authorities said the flow of ash and molten rock has now reached four and half kilometers down the slope and is threatening nearby populated villages. The ash clouds have reached three kilometers to the sky. The latest series of eruptions which began on October 5, spewed out pyroclasts and viscous lava flows from the summit vent, forcing hundreds of people to leave their homes. But despite volcanos being notoriously hard to predict, it is difficult to keep the people living on the slopes of the mountain away. http://www.dailymail.co.uk/news/article-2787764/rock-awe-indonesian-volcano- Mount-Sinabung-spews-lava-ash-continues-erupt-fourth-successive-day.html Fig. 7a Fig. 7b With reference to Fig 7a and 7b, what type of a volcano is Mount Sinabung?
