Wildfires – France

More than 1,200 firefighters were on Tuesday engaged in a “fierce struggle” against a wildfire in southeastern France.

The fire service for the Bouches-du-Rhone department said the “violent” blaze had travelled eight kilometres in under two hours. At least 1050 hectares of vegetation had been devastated. Several habitations and multiple businesses including three camping sites near the municipalities of Martigues and Port du Bouc had to be evacuated with authorities calling on people to avoid taking the taking certain roads.

Wildfires – Texas, USA

Firefighters from across the state are battling the still-growing, human-caused Mays Fire in San Saba and McCulloch counties. The fire ignited on Aug. 1, approximately 16 miles east of Brady, as the result of an individual parking and idling their vehicle over tall, dry grass. As of Aug. 4, the fire has burned an estimated 9,500 acres and is only 50% contained.

Roundup of Global Volcanic Activity – New Activity for the Week 29 July 2020 – 4 August 2020

Langila | New Britain (Papua New Guinea) : Based on analyses of satellite imagery and wind-model data, the Darwin VAAC reported that during 1-3 August ash plumes from Langila rose to an altitude of 2.4 km (8,000 ft) a.s.l. and drifted NW and W. A thermal anomaly over the volcano was visible on 3 August. Ash plumes became diffuse later on 3 August, rising to 1.8 km (6,000 ft) a.s.l. and drifting NW.

Manam | Papua New Guinea : RVO reported that seismicity at Manam began increasing on 16 July and fluctuated between low and moderate levels through the 29th. A slow steady increase of RSAM values was recorded on 30 July, and RVO stated that an observer had reported that incandescent material had been ejected from the summit. The Darwin VAAC noted that a sustained and intense thermal anomaly was visible in satellite images that same day. During 31 July-1 August ash plumes drifted NW at an altitude of 4.3 (14,000 ft) a.s.l. and a lava flow at the summit was visible.

Nishinoshima | Japan : Based on satellite data, the Tokyo VAAC reported that during 29 July-3 August ash plumes from Nishinoshima rose to 3.4-5.8 km (11,000-19,000 ft) a.s.l. and drifted in multiple directions. Strong sulfur dioxide signatures continued to be detected in satellite data.

Telica | Nicaragua : SINAPRED reported that 7-10 gas-and-ash explosions at Telica on 29 July generated plumes that rose 30-60 m above the crater rim and drifted N.

Turrialba | Costa Rica : At 0946 on 29 July an eruptive event generated a plume that rose 200-300 m above Turrialba’s crater rim. Several ash eruptions (10) were recorded for a period starting at 2010 on 30 July and ending at 0940 on 31 July. Each event lasted less than 10 minutes and plumes rose no higher than 200 m. An incandescent area was visible on the SW wall of the crater. At 0746 on 1 August a plume rose 500 m and at 0545 on 4 August a plume rose 300 m.
