Yakedake volcano (Japan) - Smithsonian / USGS Weekly Volcanic Activity Report for 16 April-22 April 2025 (Continuing Activity)

The Japan Meteorological Agency (JMA) lowered the Alert Level for Yakedake to 1 (on a scale of 1-5) at 1100 on 18 April, noting that seismicity has remind at low levels after a period of elevated seismicity was recorded during 3-9 March. JMA warned climbers to be alert to any changes at the volcano and to wear a helmet.

Kilauea volcano (United States) - Smithsonian / USGS Weekly Volcanic Activity Report for 16 April-22 April 2025 (Continuing Activity)

The Hawaiian Volcano Observatory (HVO) reported that the eruption within Kilauea’s Kaluapele summit caldera, from two vents along the SW margin of Halema’uma’u Crater, continued at variable levels during 16-22 April. Both the N and S vents were strongly incandescent and produced gas emissions on 16 April. Later that evening at around 2110 incandescence at the N vent intensified and began to eject spatter at intervals of 10-20 seconds.
Spatter bursts increased in size and frequency, and at around 2130 dome fountains 3-5 m high had formed. A lava pond in the crater rose and was visible at 2145, and by 2201 lava overflowed the crater and traveled short distances (up to 100 m) on the crater floor. Sulfur dioxide emissions were elevated.
The activity ceased at 2321. Incandescence from the S vent disappeared when the N vent overflowed but returned once the flows ceased. Both the N and S vents were strongly incandescent and produced gas emissions during 17-20 April.

At around 0745 on 20 April a narrow lava flow was produced from the S vent. Lava fountaining to 2-3 m began soon after, and by 0915 lava flows had traveled about 1 km across the crater floor. After brief pauses during 0930-0943 and 1030-1050, followed by lava flows being fed by 5-m-high dome fountains.
Lava flows and dome fountaining resumed after another break during 1110-1222, and then again ceased at 1244. Small gas-pistoning events occurred every 3-5 minutes and were superimposed upon the longer cycles of activity. Intermittent spattering at the N vent began at around 0130 on 22 April and increased in frequency.
Lava overflowed the S vent at 0320, and by 0330 lava fountaining was occurring at both vents. Lava overflowed the N vent at 0347. By 0436 the fountain at the S vent was over 200 m high and the N vent fountain was more than 50 m high, feeding lava flows that cascaded down the vent flanks and onto the crater floor.
Lava fountains at the N vent slightly grew through the day, rising as high as 60 m. The activity abruptly ceased at 1328, after lava had covered about 30 percent of the crater floor. The Volcano Alert Level remained at Watch (the third level on a four-level scale) and the Aviation Color Code remained at Orange (the third color on a four-color scale).

Lewotobi volcano (Indonesia) - Smithsonian / USGS Weekly Volcanic Activity Report for 16 April-22 April 2025 (Continuing Activity)

The Pusat Vulkanologi dan Mitigasi Bencana Geologi (PVMBG) reported that eruptive activity at Lewotobi Laki-laki continued during 16-22 April. Dense gray ash plumes rose 2.5-3.5 km above the summit on 16 April and drifted multiple directions. Ash plumes during 17-18 April rose 500-700 m above the summit and drifted mainly N and NE; weather clouds sometimes obscured views.
Multiple ash plumes per day were recorded during 19-22 April. Ash plumes rose as high as 3 km and drifted in multiple directions. An eruptive event that was recorded at 2359 on 20 April ejected incandescent material onto the upper flanks.
According to a news report, the event was accompanied by a loud banging sound heard at the Lewotobi Laki-laki observation post, 4.9 km WSW. On 22 April ash-and-gas plumes were continuously emitted from approximately 1000 at least through 1554; dense gray ash plumes rose 1.3-1.5 km above the summit and drifted W and NW, though weather clouds sometimes obscured views. The Alert Level remained at 3 (on a scale of 1-4) and the public was warned to stay 6 km away from the center of Laki-laki.

Marapi volcano (Indonesia) - Smithsonian / USGS Weekly Volcanic Activity Report for 16 April-22 April 2025 (Continuing Activity)

The Pusat Vulkanologi dan Mitigasi Bencana Geologi (PVMBG) reported that eruptive activity from Verbeek Crater at Marapi (on Sumatra) continued during 16-22 April. Ash plumes rose 200-1,000 m above the summit and drifted NE, E, SE, and S on 16, 19, and 21 April. An explosion was recorded at 2141 on 21 April but was not visually confirmed due to weather cloud cover.
According to a news report a resident Padang Panjang City (11 km SW) said that the explosion was so loud that it shook the windows. A webcam image at 2212 on 21 April showed incandescent material being ejected above the summit. The Alert Level remained at 2 (on a scale of 1-4) and the public was warned to stay 3 km away from the active crater.

Merapi volcano (Indonesia) - Smithsonian / USGS Weekly Volcanic Activity Report for 16 April-22 April 2025 (Continuing Activity)

The Balai Penyelidikan dan Pengembangan Teknologi Kebencanaan Geologi (BPPTKG) reported that the eruption at Merapi (on Java) continued during 11-17 April. Seismicity remained at high levels. The SW lava dome produced 46 lava avalanches that traveled as far as 2 km SW down the Bebeng drainage, 30 that traveled as far as 2 km SW down the Krasak drainage, and 46 that traveled as far as 2 km W down the Sat/Putih drainage.
Small morphological changes to the SW lava dome resulted from continuing effusion and minor collapses of material. The Alert Level remained at 3 (on a scale of 1-4), and the public was warned to stay 3-7 km away from the summit, based on location.

Reventador volcano (Ecuador): pyroclastic flow followed eruption

The pyroclastic flow followed vulcanian-type eruption at Reventador on 8 April (image: Benjamin Bernard)

The effusive-explosive eruption of the volcano continues and has remained essentially unchanged.
Near-constant vulcanian explosions continue to take place from the summit crater that reached 4,6 km (15,000 ft) height and drifted north and northwest over the past few days.
Multiple incandescent avalanches continue to be observed, reaching length of at least 900-1,200 meters from the summit vent.
On 8 April, an explosion generated a pumice-and-ash flow caused likely by the eruption column collapse. Pyroclastic flows are deadly, turbulent hot avalanche of lava rock fragments of all sizes embedded in a mixture of turbulent gas and ash racing down slopes
Lahars (mud flows) could also occur if heavy rainfalls remobilise the fresh ash deposits.
