Ol Doinyo Lengai is frequently the scene of fluid but very small volume lava flows in its summit crater, including a few that passed over the crater rim and begun the long descent down the mountain. As noted here last week, news reports had indicated that products of the volcano's 19-July eruption had entered inhabited areas. Subsequent investigations have cast doubt on those earlier claims.

An important new eruption initiated at Kilauea very early on 21 July. It occurred along the E rift zone from fissures trending ENE for several kilometers from Pu'u O'o. The fissures caused drainage of both the West Gap lava lake and the Puka Nui pit. Read all- More about Kilauea volcano

CVGHM lowered the Alert Level for Gamkonora from 3 to 2 (on a scale of 1-4) on 24 July based on visual observations and a decrease in seismicity. That followed a sharp drop in seismicity during 8-23 July, a decline both in terms of the number of events and their energy. Later, during 16-23 July, when breaks in inclement weather took place, observers saw white plumes rising to altitudes of 5.6 km (18,400 ft) a.s.l. Read all- More about Gamkonora volcano

As noted by the IG in their daily reports covering 25-31 July, Tungurahua emitted a substantial number of small ash-bearing explosions and several unusually large ones as well. Based on ground observer estimates, many plumes during the reporting interval rose to 2-3 km above the crater rim (up to ~1 mile above the crater) and dropped ash on towns located on the volcano's flanks.

A KVERT report issued for Karymsky on 27 July stated the following, "The eruption of the volcano continues. Ash explosions up to 6 km (or 19,700 ft.) a.s.l. are possible at any time.

On July 21, the activity inside Pu'u 'O'o cone ceased, and a new intrusion made its way to the surface in the area east of the cone and uprift from Kupaianaha shield (active in the 1990s). More news and photographs about this remarkable change in the ongoing eruption can be found at HVO's update pages: http://volcano.wr.usgs.gov/hvostatus.php.

As more news has become available, the news about an effusive flank eruption at Lengai around 15 July turns out to be probably false. The observed "ashcloud" was dust from a landslide. This demonstrates how difficult it is in this area to have robust information. The ongoing seismic activity in the Gregory Rift, however, is quite peculiar.

Based on a Significant Meteorological Information (SIGMET) advisory, the Buenos Aires VAAC reported that an ash plume from Ubinas rose to an altitude of 6.1 km (20,000 ft) a.s.l. and drifted SE on 22 July. Ash was not identified on satellite imagery. Read all- More about Ubinas volcano

According to news reports, an eruption began at Ol Doinyo Lengai around 19 July, forcing villagers living near the volcano to evacuate. An article stated that, "...more than 1,500 people,most of them Maasai families,vacated their homes in Ngaresero,Orbalal and Nayobi villages following the tremors that triggered the volcanic eruption." "Villagers are reported to have heard roaring...before the volcano started discharging ash and lava." There were reports of a damaged school and two injuries, but no reports of deaths.

During 18-21 July, the E vent and dominant W vent in Kilauea's Pu'u 'O'o produced lava flows. On 18 July, new vents opened in the Puka Nui pit, in the SSW area of Pu'u 'O'o crater, and produced lava flows that ponded. On 20 July, a vent high on the S crater wall, adjacent to the Puka Nui Gap pit, produced spatter and propelled lava bombs 10 m into the air. Read all- More about Kilauea volcano

INSIVUMEH reported that during 17-18 July, gas plumes from Fuego rose to an altitude of 3.9 km (12,800 ft) a.s.l. and drifted SW. On 18 July, a hot lahar, 20 m wide and 1.5 m high, carried blocks 1-1.5 m in diameter to the W down the Santa Teresa ravine. Read all- More about Fuego volcano

AVO raised the Volcanic Alert Level for Cleveland from Advisory to Watch and the Aviation Color Code from Yellow to Orange on 20 July. The change in Alert Level was based on the presence of an intense thermal anomaly in the crater and associated steam-and-gas plume observed on satellite imagery. The thermal anomaly continued to be detected on satellite imagery during 22-23 July. Read all- More about Cleveland volcano

The lava lake inside the Puu Oo crater as on 11 July.
Over the past week, the lava lake inside the Puu Oo crater became less and less alimented, dropped several meters inside an 8-shaped system of levees. It remaining active in this smaller area, fed by the eastern vent, but by yesterday, its activity appears to have ended according to information from HVO. Instead, new vents have become active in the western area of the Puu Oo cone.
