![]() The ash plume rose to 18 km altitude and dispersed ash to the W and NW of the volcano. Tavurvur, the active stratovolcano of Rabaul caldera, on 29 August 2014. High levels of seismic tremor were recorded during the eruption.įigure 68. Villages to the E and S were not affected by ash, but ashfall was reported in Keravat, about 25 km SW. Rabaul Town, 7 km NW of Tavurvur, was initially affected by ash, as was Volavolo (20 km W), but a shift in wind direction sent the plume in a more WNW direction by mid-morning. At dawn, the eruption plume could be seen blowing W over the Malguna villages, about 8 km NW, at an altitude of 3,000 m (figure 68). ![]() The stronger explosions generated shockwaves which rattled windows and doors in the area. The activity on 29 August 2014 started slowly between 03 local time and then developed into a Strombolian eruption accompanied by loud explosions, roaring, and rumbling. Matupit Island is the peninsula immediately W of Tavurvur. Locations of ground deformation (red), seismic (green) and thermal (orange) monitoring stations around Tavurvur volcano at Rabaul Caldera, New Britain Island, Papua New Guinea. An explosion occurred on 6 August, and an inspection of the summit crater on 8 August revealed an incandescent area covered by debris.įigure 67. In the days immediately before the 29 August 2014 eruption, Tavurvur had been emitting a diffuse plume of white vapor. ![]() Prior to August 2014, DMPGM reported that ground deformation measurements from the GPS station on Matupit Island (3 km W) had been showing increasing inflation, first detected in March 2014 (figure 67). The volcano remained quiet after this and through 2016, although ground deformation data indicated a gradual inflation of about 6 cm over the period.Īctivity during August-December 2014. After this, plumes of white vapor and slightly bluish gas returned, except for an ash plume reported on 12 September and a small explosion on 18 September. Smaller explosions at irregular intervals continued through 0641 on 30 August. This was followed by an ash plume rising to 18 km altitude. A number of news outlets also covered the eruption with photographs, videos, and interviews of local residents.Ī Strombolian eruption at Tavurvur began shortly after 0330 local time on 29 August 2014. Aviation alerts for Rabaul are issued by the Darwin Volcanic Ash Advisory Center (VAAC). Additional information for the 2014 eruption, and subsequent activity covered in this report, was compiled by the Rabaul Volcano Observatory (RVO) and issued by the Department of Mineral Policy and Geohazards Management of Papua New Guinea (DMPGM). During the 1994 eruption, a lava flow, tephra ejection, and an ash plume rising to 18 km caused the evacuation of over 50,000 people from the surrounding area, significant damage to nearby Rabaul Town, several deaths, and disrupted air traffic for several days (BGVN 19:08, 19:09). The volcano has been intermittently active since a major eruption in September 1994, which was its first eruption in over 50 years. The large eruption of 29 August 2014 at the Tavurvur stratovolcano of Rabaul caldera, on the NE tip of New Britain Island in Papua New Guinea, followed a period of minor ash eruptions earlier in the year (BGVN 39:08). ![]() Details of 29 August 2014 Strombolian eruption update through 2016
