The PVMBG volcano observatory reported that an increased seismic activity has been registered.

The PVMBG volcano observatory reported that recent observations from May showed no significant signs of the elevated activity at the volcano leading to an eruption anymore.
PVMBG had raised the Alert Level for Awu to 2 (on a scale of 1-4) on 12 December 2021 because of a notable increase in the number of both shallow and deep volcanic earthquakes. Since then the number of shallow and deep volcanic earthquakes averaged 8 and 5 events per day, respectively. Gas emissions had not been visible, though weather conditions sometimes prevented views of the volcano.

The Volcanic Alert Level of the volcano was raised from Level 2 (valid from 12 December 2021) to Level 3, as an increase of volcanic earthquakes has been registered over the past three days.
PVMBG reported that volcanic seismicity at Awu had increased beginning in October. Notably, the number of shallow volcanic earthquakes increased to 7-26 events per day from the previous maximum of 5 daily events. The number of deep volcanic earthquakes also increased.

The alert level for the volcano was raised to Level 2 today, as an increase of seismic activity has been recorded since October.
The Darwin VAAC reported that on 4 August an ash plume from Awu was visible in satellite images rising to an altitude of 1.8 km (6,000 ft) a.s.l. and drifting N.

PVMBG reported that seismicity at Awu fluctuated but declined during 1-30 October; the maximum number of shallow and deep volcanic earthquakes were eight and three, respectively, which were in the normal range. Solfatara plumes rose as high as 25 m above the vent. The Alert Level was lowered to 1 (on a scale of 1-4) on 31 October.

PVMBG reported that the number of earthquakes at Awu had risen significantly on 11 May and remained elevated through 14 May; a downward trend in seismicity became evident on 21 May. Earthquake hypocenters were located at depths between 1 and 2 km. The Alert Level was lowered to 2 (on a scale of 1-4) on 14 June; residents and tourists were advised to stay 4 km away from the crater.

Volcanic hazard map of Awu volcano (VSI)
VSI raised the alert level of the volcano from 2 ("waspada") to 3 ("siaga" = eruption warning) yesterday - presumably because of increased seismic activity observed.

PVMBG reported that seismicity at Awu fluctuated during April and the first part of May. On 11 May the number of earthquakes rose significantly; the number of local tectonic and deep volcanic earthquakes was the highest recorded in the last year, and the number of shallow volcanic earthquakes was the second highest recorded (the highest number was recorded on 24 November 2015, prompting an increase in the Alert Level). Earthquake hypocenters were located at depths between .5 and 4 km.

PVMBG reported that on 24 November the number of shallow volcanic earthquakes at Awu increased significantly from a baseline maximum of 4 per day to 258 events; only seven events were recorded the next day. Seismicity continued to decline during 2-15 December. Fog prevented visual observations of the crater.

Last week, PVMBG raised the alert level of Indonesia's northernmost known active volcano a notch, as small signs of new unrest had been detected recently: mostly, this is an increase in shallow seismic activity since the summer and more pronounced since the middle of November.

PVMBG reported that during 1-24 November the seismic network at Awu detected a significant increase in seismicity, especially in the number of shallow volcanic earthquakes (from a baseline maximum of 4 per day to 74 events on 24 November). The Alert Level was increased to 2 (on a scale of 1-4). Fog prevented visual observations.

During 15-16 June, there was no significant volcanic or seismic activity at Awu. "White smoke" rose about 50-100 m above the summit. Awu remained at Alert Level 3 (on a scale of 1-4).

On 13 June, DVGHM reduced the Alert Level at Awu from 4 (the highest level) to 3 after volcanic activity decreased. On 9 June, two moderate explosions rose about 2 and 3 km above the volcano. Ash drifted SW and was deposited in the villages of Tabukan utara and part of Kendahe, and at the Taha airport.

According to news reports, Awu began erupting small ash plumes on 5 June. On 7 June, following a 48-hour-long period of increasing activity, authorities raised the Volcano Warning Level from Alert to Ready at 1040 and finally to Beware, the highest level of alert, at 1600. By 8 June, continuous small earthquakes were occurring and small eruptions produced gas-and-ash plumes and threw small ballistics up to 2 km above the summit.

DVGHM reported a sudden increase in seismicity at Awu beginning on 16 May when 12 volcanic earthquakes were recorded. In addition, tremor was recorded during 1110-1540. Gas plumes rose ~75 m above the crater that were thicker than earlier in the month, but they did not change color or form clumps.

Seismicity increased at Awu on 15 November, but during 19-24 November decreased back to "normal levels." There were no surface changes around the volcano's summit. Awu remained at Alert Level 2 (on a scale of 1-4).

VSI increased the Alert Level at Awu on 15 November following an increase in seismicity. Normally four earthquakes occur per day at the volcano, but 32 volcanic earthquakes were recorded on 15 November during 0000-0900. No surface changes were observed around the volcano's summit.
