Volcano: Rinjani Volcano: Bagana
 * Date || Description ||
 * 30 Dec-5 January || The Darwin VAAC reported that an ash plume rose to an unspecified altitude on 2 January. A meteorological cloud was present in the area. This information is based on a pilot report. ||
 * 28 April- 4 May || During February, CVGHM reported that people observing at a post located 12.5 km NE of Rinjani saw a white plume rising 100 m. 26 times in March, dense white and possibly brown plumes rose 500-900 m. 41 times in April, plumes rose as high as 1,500 m. On May 1 and 2, chocolate colored plumes rose 1,600 m at the maximum. Seismicity decreased during February through April, although the maximum earthquake amplitude increased. Ash and glowing material fell within Rinjani caldera. Some ash was blown out of the caldera. The Alert Level rose to 2 (on a scale of 1-4), on 2 May. ||
 * 5 May-11 May || The Darwin VAAC reported that an ash plume rose 5.5 km high and drifted 150 km NW, on 5 May. CVGHM advised the VAAC that intermittent activity could produce ash plumes to one and a half km above the caldera. This information is based on satellite images. ||
 * 19 May-25 May || Rinjani erupted 3 times during 22-23 May, accompanied by tremors. Ash and glowing material shot out 2 km. There were ashfalls in multiple areas, which were caused by ash plumes drifting.The Caldera Lake's water temperature rose 21-35 degrees celcius because lava flowed into it. ||

 * 5-11 December 2007 || RVO reported that during 18 October-10 December there were white vapor plumes and occasionally ash plumes from Bagana. The ash plumes were made by rockfalls from the edges of the lava flow on the southeast flank. Booming and roaring noises were heard occasionally and the summit was glowing. Two explosions were accompanied by ash plumes on 19 and 27 November. Lighted lava pieces were ejected from the summit on 7 and 9 December. An ash plume rose 2.8 km on 9 December. Lava was flowing. ||
 * 21 April-27 April || The Darwin VAAC reported that ash plumes from Bagana rose to 1.5-3 km high and drifted 35-85 km S, SW, W, and NW, during 19-20, 23, 25, and 27 April. This information is based on satellite images. ||
 * 12 May-18 May || The Darwin VAAC reported that on 12 May, an ash plume from Bagana rose 2.4 km high and drifted 55-75 km W and WSW. This information is based on satellite images. ||
 * 30 June-6 July || The Darwin VAAC reported that on 4 July, an ash plume from Bagana rose 2.4 km and drifted 75 km west. This information is based on satellite images. ||
 * 29 Sept-5 Oct || On Oct 1, the Darwin VAAC reported that an ash plume rose from Bagana to an altitude 2.4 km and drifted 75 km NW. This info is based on analyses of satellite images. ||
 * Summary || In early December of 2007, lava was ejected from the summit of my volcano, Bagana. Since then the only thing that has happened are ash plumes rising and drifting. The ash plumes' altitude ranges from 1.5 kilometers which is the lowest, to 3 kilometers which is the highest. 3 of the four ash plumes rose to 2.4 kilometers. The other one rose to 1.5-3km. ||
 * 7 Feb 2011 || Nothing happened. D: ||
 * 11March2011 || Still nothing happened D: D: ||
 * 16 March-22 March 2011 || During 18-19 March, ash plumes from Bagana rose 2.4 km and drifted 75-110 km SW. ||
 * 23 March-29 March 2011 || During 25-28 March ash plumes from Bagana rose 2.1 km and drifted 35-100 km NW, W, and SW. ||
