On 24 April at 2050 Popocatépetl issued a moderate explosion that threw incandescent fragments 1.5-2.0 km above the crater and generated an ash column that rose to ~2.5 km above the crater. The plume was initially carried E. This activity was related to the destruction of a small dome that formed in the past few days. Read all- More about Popocatépetl volcano

A KVERT report on Kliuchevskoi issued on 25 April stated that above-background seismicity, including abundant tremor, prevailed during the week. This report also revealed that the ash explosions of 17-18 April had sent material 1-2 km above the crater. Modest thermal anomalies registered in satellite data for 18-19 April and plumes around that time extended E for 20-200 km. Read all- More about Klyuchevskoy volcano

For the week ending 29 April eruptive activity continued unabated from the Pu`u `O`o vent of Kilauea. The flows on Pulama pali were frequently visible at night as streams of incandescence from the top of the pali down to the coastal flats. Late in the previous week and early in this week, the east arm of the Mother's Day flow split in two with the western segment being more active. Read all- More about Kilauea volcano

KVERT reported that Karymsky's seismicity was above background during the week ending 25 April, an interval when instruments registered ~40-100 volcanic earthquakes per day. The character of the seismicity suggested ash-and-gas explosions up to 1,000 m above the volcano's crater. According to Russian satellite data, ash deposits were detected ~35 km away in various directions from the volcano; these were noted the previous week, on 19-22 April, but not previously reported here.

During the week Guagua Pichincha continued to display seismic unrest, typically with several earthquakes per day but including 16 long-period earthquakes on 26 April. During 23, 24, 26, and 27 April observers on the mountain typically smelled sulfur, but qualitative assessments of fumarolic output varied. In conditions of poor visibility, observers sometimes heard the sound of gases escaping in the crater. Read all- More about Guagua Pichincha volcano

The Washington VAAC reported that on 28 April Fuego produced intermittent ash eruptions. One cloud was observed at ~ 7 km a.s.l., traveling SW at 19-29 km per hour. Although remote sensing was complicated by poor visibility due to high cirrus clouds and smoke from fires, some eruptive puffs remained recognizable when they blew over the coast.

Chikurachki, a volcano located on Paramushir Island in the North Kuriles, began erupting on 18 April 2003. A KVERT update for 25 April stated that the eruption continued and satellite data confirmed that ash plumes had moved SE and occasionally E during 22-25 April. The plumes attained lengths over 100 km. Read all- More about Chikurachki volcano

The ongoing eruption at Popocatépetl was punctuated by a small explosion on 17 April, an event accompanied by incandescent fragments that reached 1 km E along the summit crater=s outer margin, and a modest ash plume directed toward the NE. Associated with the event, low-amplitude tremor persisted for about 2 hours, but no other significant geophysical changes were seen. More typical low-intensity outbursts also continued during the week, typically at rates of ten=s per day. Read all- More about Popocatépetl volcano

Miyake-jima has remained restless since its summer eruption in 2000, with robust degassing ongoing through the week of 16-22 April. The SO2 gas output (flux) remained high (about 5,000-10,000 tons/day) as of March 2003. All people who lived on Miyake-jima island have been evacuated since September 2000 and SO2 fluxes around that time had reached extremely high values, over 80,000 tons/day.

Llaima remained at Yellow alert at least through 16 April and eruptions began to contain significant tephra. Seismicity was almost 5-fold above background. Volcanologists expressed concern that the volcano=s glacial ice-cover could undergo local melting, which might lead to large and sudden outbursts of water (glacier bursts) down local drainages.

A moderate vulcanian eruption of Kliuchevskoi began 15 April; it continued through at least 16 April. The eruption was preceded by above-background seismicity, and on 15 April there were ~70 earthquakes per day at ~30-km depth. Instruments registered continuous spasmodic volcanic tremor (up to 4.0 µm/second) and numerous weak shallow earthquakes. Read all- More about Klyuchevskoy volcano

During the week ending 22 April, Kilauea continued to erupt, sending lava down its SE flank either traveling over the land surface or through tubes. Lava entered the sea at the West Highcastle entry; activity there was sometimes weak, though one or more glowing areas were typically seen. Read all- More about Kilauea volcano

Karymsky's eruptive vigor increased. Although seismicity stood at background levels during the past week and slightly above background levels on 14 April, ten=s of volcanic earthquakes per day began to be registered. Observations made on 16 April suggested the presence of fresh ash deposits extending to the ESE for a distance of over 10 km from the summit. Read all- More about Karymsky volcano

Karangetang's S crater gave off ash emissions that reached 250 m high during the week of 16-22 April. Just prior, on 15 April, an explosion that sounded like a blast was followed by lava avalanches traveling S and W and reaching ~1 km from their source at S crater. The resulting dark-gray ash column reached 1.5 km above the crater. Read all- More about Karangetang volcano
