On 17 August, CVGHM raised the Alert Level for Talang from 2 to 3 (on a scale of 1-4) because of increased seismicity during the previous two days. Foggy conditions prevented visual observations. Visitors and tourists were advised not to go within a 3-km radius of the summit.

12 December 2007              Back to Top

CVGHM lowered the Alert Level at Talang to 2 (on a scale of 1-4) on 14 December based on visual observations and a decrease in the number of earthquakes. During 7-10 December, observations of the summit were limited by inclement weather. On 11 December, "smoke" rose to a maximum altitude of 3.3 km (10,800 ft) a.s.l. from the Main crater. Plumes were also observed from South crater and Gabuo Atas solfatara field. Visitors were advised not to go within a 2-km radius of the summit.

CVGHM raised the Alert level for Talang from 2 to 3 (on a scale of 1-4) on 29 November based on visual observations and seismicity. Ash and steam plumes from multiple craters rose to altitudes of 3.1-4.1 km (10,200-13,500 ft) a.s.l. during 27-29 November. A strong smell of sulfur dioxide gas was also reported.

24 January 2007              Back to Top

CVGHM lowered the Alert Level at Talang to 2 (on a scale of 1-4) on 27 January due to a reduction in seismic activity since 23 November 2006 to 24 January 2007. Gas plumes were present from the South Crater and the Main Crater.

6 September 2006              Back to Top

CVGHM raised the Alert Level at Talang to 3 (on a scale of 1-4) on 9 September due to an increase in tremor. On 10 September, a brownish plume rose 250 m above the summit (~10,000 ft a.s.l.).

20 July 2005              Back to Top

DVGHM increased the Alert Level at Talang from 2 to 3 on 18 July due to an increase in seismicity at the volcano. During 15-18 July, the seismic network recorded 93 deep volcanic earthquakes, one low-frequency tremor, and three "felt shocks" around the N slope of the crater. Minor phreatic activity occurred at the southern and northern slope craters, with ash plumes rising 0.5-1.5 km above the crater (11,100-14,400 ft a.s.l.).

6 July 2005              Back to Top

Small phreatic eruptions occurred at Talang on 2 and 3 July. The eruptions occurred at the main crater, and a crater on the volcano's S slope. Ash columns reached 300-500 m above the volcano (10,500-11,100 ft a.s.l.). Gabuo Atas, Gabuo Bawah, and Kapundan Panjang craters on the volcano's N slope emitted steam to low altitudes. Talang remained at Alert Level 2 (on a scale of 1-4). Visitors were not permitted to enter within a 1 km radius of the active craters.

27 April 2005              Back to Top

Due to a decrease in seismicity at Talang during 24-28 April, DVGHM reduced the Alert Level from 3 to 2 (on a scale of 1-4) on 28 April. Visitors were still not permitted to enter within a 1 km radius of the crater.

13 April 2005              Back to Top

According to DVGHM, the eruption that began at Talang on 12 April ended on 14 April. During 14-17 April, the intensity of the activity at the volcano decreased so DVGHM reduced the Alert Level from 4, the highest level, to 3. People were permitted to return their homes near the volcano, but no one could enter within 1 km of the summit.

On 12 April during 0340-0600, an eruption at Talang produced an ash plume that rose to a height of ~1 km above the crater (~12,800 ft a.s.l.). About 4 mm of ash fell in the village of Bukit Sileh, NE of the volcano. The Alert Level was raised to 4, the highest level. News articles reported that thousands of residents near the volcano evacuated. Several days prior to the eruption, a "gray ash cloud" was visible rising to ~100 m above the volcano's summit (9,800 ft a.s.l.).

On 13 April volcanic and seismic activity decreased in comparison to the previous day. A "white-gray ash plume" rose 250 m (10,300 ft a.s.l.) above Kawah Mati crater, and gas was emitted from Gabuo Atas crater. There was a decrease in the number of deep volcanic, shallow volcanic, and explosion earthquakes. Talang remained at Alert Level 4.

28 November 2001              Back to Top

During 19 November- 2 December seismicity at Talang was dominated by small explosion earthquakes. In addition, there was an increase in deep volcanic earthquakes in comparison to the previous week. During 19-25 November an increase in tectonic earthquakes was recorded. Thin plumes rose ~50 m above Gabuo Atas and Kepundan Panjang fumarole fields. The volcano remained at Alert Level 2 (on a scale of 1-4).

26 September 2001              Back to Top

During 24-30 September volcanic activity increased at Talang volcano. Observers noted that on 25 September during 1722-1838 a thick white-brownish plume with high gas pressure rose 200-350 m above the volcano. Personnel at the observatory could smell sulfur during the evening. In comparison to measurements in 2000, temperatures increased in 2001 at Batu Bajanjang hot spring (from 40-60°C to 45-66°C), Gabuo Atas fumarole field (from 98-99°C to 111-114°C), and Gabuo Bawah fumarole field (from 96-99°C to 100-101°C). In addition, the water level at Batu Bajanjang hot spring decreased drastically. Talang was at Alert Level 2 (on a scale of 1-4).

Talang, which forms a twin volcano with the extinct Pasar Arbaa volcano, lies ESE of the major city of Padang and rises NW of Dibawah Lake. Talang has two crater lakes on its flanks; the largest of these is 1 x 2 km wide Danau Talang. Most historical eruptions have not occurred from the summit of the volcano, which lacks a crater. Historical eruptions from Gunung Talang volcano have mostly involved small-to-moderate explosive activity first documented in the 19th century that originated from a series of small craters in a valley on the upper NE flank.
