KuvaEtna (Italy)

Sezione di Catania - Osservatorio Etneo (INGV) reported that an eruption at Etna continued during 3-9 July, with activity intensifying on 4 July and producing substantial ashfall in areas downwind during 4-7 July. Strombolian activity at Voragine Crater intensified during 2-3 July and lava continued to flow into Bocca Nuova Crater. During the evening of 3 July Dipartimento della Protezione Civile raised the Alert Level to Yellow (the second lowest level on a four-level scale). Strombolian activity at Voragine notably intensified during the morning of 4 July and tremor amplitude further increased around 1420. Two lava flows from two vents located on the SE and NW sides of the growing scoria cone continued to flow into the Bocca Nuova. Bombs and scoria were ejected hundreds of meters high. The Strombolian activity changed to tall lava fountaining at 1815 and produced ash-and-gas plumes that rose to about 4.5 km a.s.l., or over 1.1 km above the summit, and drifted SE. Notable ashfall was reported in several areas downwind as far as Catania (29 km SSE). The lava fountaining gradually decreased through the night and ceased at around 0350 on 5 July; about an hour of Strombolian activity followed. Ash-and-gas emissions continued to rise to the same height as the previous day and drifted SE. Significant ashfall was reported in areas downwind and beyond Syracuse, 60-80 km SSE. According to a news article the airport in Catania closed due to ash on the runways; operations resumed by 1500, though some flight restrictions were in place. The amplitude of volcanic tremor fluctuated between medium and high levels. Strombolian activity resumed during the afternoon on 6 July. The activity intensified at around 0000 on 7 July and changed to lava fountaining by around 0400. Ash emissions rose about 9 km a.s.l. (about 5 km above the summit) and drifted ESE, causing significant ashfall to the E, especially in the area between Zafferana Etnea (10 km SE) and Giarre (17 km ESE). At around 0850 lava overflowed the NW rim of Bocca Nuova Crater and traveled just over 500 m, stopping at around 3,000 m elevation. Sporadic ash emissions at Southeast Crater were observed. The lava fountaining gradually weakened and ceased at around 1000 and was followed by Strombolian activity that also gradually weakened and then ceased after about an hour. A more notable ash emission from Southeast Crater occurred at 1141 and rapidly dissipated. By 1228 minor ash emissions continued to occur and lava continued to flow from the summit craters.

KuvaStromboli (Italy)

INGV reported a period of intense activity at Stromboli that included spattering, lava overflows from a series of vents along the Sciara del Fuoco, pyroclastic flows, and debris avalanches. During 1-3 July low- to medium-intensity explosive activity at two vents in Area N (one at N1 and one at N2) and in sector S2 (Area C-S) ejected coarse material (bombs and lapilli) less than 150 m above the vents. Explosive activity at S2 decreased and then stopped on 3 July. A gradual increase in the amplitude of seismic tremor from medium to high levels began at around 1730 on 3 July. A sudden increase in amplitude to very high levels occurred at about 1820 and the amplitude peaked 20 minutes later, concurrent with stronger spattering in Area N at 1835. A series of about 20 collapses at the cone began at around 1845, producing avalanches of incandescent material that rapidly descended the Sciara del Fuoco, reached the coastline, and spread out over the sea. The activity produced ash clouds that drifted over the S and E parts of the island. Spattering and explosive activity followed, and at 1902 lava overflowed Area N, descended the upper part of the Sciara del Fuoco, and produced block avalanches that rolled down the flank. At about 1905 tremor amplitude rapidly decreased but remained at high levels. Lava flows continued to be fed through the night, reaching 550-600 m elevation, but ceased in the morning and cooled. A period of almost continuous landslides occurred at N2 during the early afternoon of 4 July. At around 1410 on 4 July a lava flow from a new vent at 700 m elevation in Area N descended the Sciara del Fuoco along with a pyroclastic flow. At 1714 the lava branched at around 600-650 m elevation and traveled parallel to the first, reaching the coastline at 1747. At 1818 a new vent with a high lava effusion rate opened at around 510 m elevation. Both the lava flow and a simultaneously generated pyroclastic flow rapidly descended the Sciara del Fuoco to the coastline, where the pyroclastic flow spread over the sea for several hundred meters. An ash plume rose 2 km a.s.l. Numerous additional pyroclastic flows descended the Sciara del Fuoco; the most notable one occurred at 2010 and again spread several hundred meters over the water. At 2000 the Dipartimento della Protezione Civile raised the Alert Level to Red (the highest level on a four-level scale). Lava flowed down to the coast on 5 July and produced steam-and-ash plumes where it contacted the sea. Tremor amplitude fluctuated between high and very high values and then decreased to average values by 0600. A sequence of pyroclastic flows at 1219, 1227, 1230, and 1233 quickly descended the flank and reached the sea; another descended the Sciara del Fuoco at 1431. By 1536 fresh lava supply to the flow had decreased, and material breaking from the flow front was rolling down the flank. Effusive activity increased at around 2055 based on field observations and a lava flow descended the flank, stopping a few tens of meters from the coastline; effusion again stopped. Lava effusion restarted by 1321 on 6 July from a vent at 485 m elevation and produced a lava flow that traveled about 285 m. Blocks detached from the flow front and rolled down the flank to the sea. Effusive activity intensified during 6-7 July. Lava from vents at 510 m and 485 m elevation converged and flowed down the flank to the coast, creating a small lava delta and producing ash-and-steam plumes. Incandescent lava blocks rolled down the flanks and caused small phreatic explosions when they reached the sea.

KuvaPurace (Colombia)

Observatorio Vulcanológico y Sismológico de Popayán, Servicio Geologico Colombiano (SGC) lowered the Alert Level for Puracé to Yellow (the second lowest level on a four-color scale) on 5 July noting that activity had declined and stabilized. Seismicity had increased around 24 April, peaked during 30 May-6 June with the highest daily number of earthquakes recorded since instrumental monitoring began, and then declined to pre-unrest levels during the past few weeks. The magnitudes of the earthquakes decreased to less than M1. Sulfur dioxide emissions also decreased during the previous few weeks and deformation rates were similar to those detected before the period of unrest.

KuvaSabancaya (Peru)

Instituto Geofísico del Perú (IGP) reported that the eruption at Sabancaya continued at moderate levels during 1-7 July with a daily average of 40 explosions. Gas-and-ash plumes rose as high as 2.9 km above the summit and drifted less than 10 km E and SE. Thermal anomalies over the lava dome in the summit crater were identified in satellite data. Slight inflation was detected near the Hualca Hualca sector (4 km N). Sulfur dioxide emissions were at moderate levels, averaging 497 tons per day. The Alert Level remained at Orange (the third level on a four-color scale) and the public was warned to stay outside of a 12 km radius.
