Episodes of weak lava fountaining during 6-10 March were accompanied by ash plumes that rose 100-300 m above the crater and drifted mainly SW. Rumbling sounds were audible at least within a 10-km radius. Active lava flows extended 3.3 km, 4.5 km, and 1.9 km long in the Mi-isi (S), Bonga (SE), and Basud (E) drainages, respectively. Steam plumes rose 2.4 km and drifted SW on 10 March. The next day white-and-gray plumes rose 2.5 km and drifted SW. The Alert Level remained at 3 (on a 0-5 scale) and PHIVOLCS reminded residents to stay away from the 6-km-radius Permanent Danger Zone and the 7-km Extended Danger Zone on the SSW and ENE flanks.

KuvaEbeko (Russia)

Based on observations by volcanologists in Severo-Kurilsk (Paramushir Island), about 7 km E of Ebeko, explosions on 6 March generated ash plumes that rose as high as 1.7 km (5,600 ft) a.s.l. The Aviation Color Code remained at Orange (the second highest level on a four-color scale).

KuvaDukono (Indonesia)

Based on analyses of satellite imagery and wind model data, the Darwin VAAC reported that during 7-13 March ash plumes from Dukono rose to altitudes of 1.5-3 km (5,000-10,000 ft) a.s.l. and drifted in multiple directions.

KuvaAmbae (Vanuatu)

Based on satellite and webcam observations, and model data, the Wellington VAAC reported that during 12-13 March ash plumes from Ambae rose to an altitude of 3 km (10,000 ft) a.s.l. and drifted SW.

KuvaKirishimayama (Japan)

According to news articles, ash plumes from Shinmoedake (Shinmoe peak), a stratovolcano of the Kirishimayama volcano group, caused the cancelation of about 80 flights in and out of Kagoshima airport on 6 March. JMA reported that daily explosions during 6-13 March generated ash plumes that generally rose 3 km above the crater rim, though an ash plume on 10 March rose as high as 4.5 km. Explosions also ejected tephra that fell 700-1,800 m from the vent. Ashfall was reported in a wide area including in the prefectures of Nagasaki, Kumamoto, Miyazaki, and Kagoshima. An explosion at 1558 on 9 March rattled structures in the Kagoshima and Miyazaki prefectures. Satellite images showed an increase in the crater diameter from 550 m on 7 March to 650 m on 9 March. During overflights on 9 March observers noted white plumes rising from the margins of the lava covering the crater floor, from lava flows on the S flank, and from newly forming lava flows on the NW flank. The volume of erupted lava was an estimated 14 million cubic meters. The NW lava flow had advanced 226 m by 13 March. A high number of volcanic earthquakes continued to be recorded, in addition to many low-frequency earthquakes with shallow hypocenters. Volcanic tremor was continuous from 1 March until 1536 on 8 March; afterwards the signals had small amplitudes and were intermittent. The Alert Level remained at 3 (on a scale of 1-5).

KuvaAgung (Indonesia)

PVMBG reported that although there were sometimes foggy conditions during 7-13 March, white plumes were observed rising as high as 600 m above Agung?s crater rim and drifting E. An event at 2332 on 11 March generated an ash plume that rose about 950 m and drifted E. The Alert Level remained at 3 (on a scale of 1-4) and the exclusion zone continued at a 4-km radius.

KuvaKick 'em Jenny (Grenada)

The University of the West Indies (UWI) Seismic Research Centre (SRC) and the National Disaster Management Agency (NaDMA) reported that on 12 March the Alert Level for Kick 'em Jenny was raised to Orange (the second highest level on a four-color scale) due to non-specified increased activity. The report reminded marine operators of the 5-km maritime exclusion zone.

KuvaTurrialba (Costa Rica)

RSN and OVSICORI-UNA reported that a new eruptive phase at Turrialba began at 2240 on 6 March with minor ash emissions that rose 500 m above the vent rim and drifted NW. The activity intensified around midnight, with dense ash emissions and the ejection of incandescent blocks, and remained elevated almost until 0300 on 7 March. At 1740 activity again intensified; emissions with an increased volume of ash was recorded by the webcam from 1801-1820 drifting W. OVSICORI-UNA reported that events at 1515 on 8 March and 0920 on 13 March generated ash plumes that rose 300 m and drifted SW and NW, respectively.

KuvaNevados de Chillan (Chile)

Servicio Nacional de Geología and Minería (SERNAGEOMIN) Observatorio Volcanológico de Los Andes del Sur (OVDAS) reported continuing activity during 16-28 February associated with a low rate of growth of the Gil-Cruz lava dome in Nevados de Chillán?s Nicanor Crater. Continuous gas emissions from the SE-NW-trending fissure on the dome?s surface were punctuated by emission of ash and water vapor that rose no higher than 1.8 km. During an overflight on 22 February observers noted an increased volume of the dome compared to the previous observation. The Alert Level remained at Yellow, the middle level on a three-color scale, and the public was reminded not to approach the craters within a 4-km radius.

KuvaPopocatepetl (Mexico)

CENAPRED reported that each day during 7-13 March there were 105-361 steam and gas emissions from Popocatépetl. Incandescence from the crater was visible at night. Explosions were recorded on 7 March. An explosion at 1042 on 12 March generated an ash plume that rose 1.5 km above the crater rim and drifted SE. The Alert Level remained at Yellow, Phase Two.

KuvaReventador (Ecuador)

During 6-13 March IG reported a high level of seismic activity including explosions, long-period earthquakes, harmonic tremor, and signals indicating emissions at Reventador. Steam, gas, and ash plumes sometimes rose higher than 600 m above the crater rim and drifted N, NW, and W. Incandescent blocks rolled as far as 800 m down the flanks. On 13 March a pyroclastic flow traveled 400 m down the S flank. Weather clouds sometimes prevented visual observations.
