Indonesia – Indonesia’s disaster agency reported that 15,0000 homes were damaged in dozens of flood and landslide events throughout June this year. A total of 137 natural disasters across the country throughout June 2021, including earthquakes, forest fires and tornadoes. However, the agency said hydrometeorological disasters still dominate natural disasters in the country, with as many as 33 floods and 39 landslides occurring in June this year. Over 30 people were injured and 2 people died in flood- and rain-related disasters in June. As many as 15,000 homes were flooded.

Environment

Hottest June in North America

If the melting power cables in Portland, Oregon, weren’t enough of an indication, new satellite data confirms what many sweat-drenched Americans could have guessed: June 2021 was the single hottest June on record in North America.

The month saw record heat waves blast the Pacific Northwest and western Canada, with stagnant air bearing down on densely populated cities, like Seattle and Portland, for several days in a row. The culprit was a dangerous weather phenomenon called an omega block, which is essentially a dome of hot air trapped in place by atmospheric currents.

Roundup of Global Volcanic Activity – New Activity for the Week 30 June – 6 July 2021

Copahue – Central Chile-Argentina border : SERNAGEOMIN and SEGEMAR reported increased activity at Copahue, beginning with minor, sporadic increases in tremor first detected at the end of May. During 30 June-2 July tremor was elevated and volume of water in the crater lake decreased significantly. Coincidently crater incandescence was visible in nighttime webcam views and gas emissions increased. Residents reported volcanic gas odors. Increased gas-and-steam emissions during 1100-1400 on 2 July contained minor amounts of ash that left visible deposits on the SE and ENE flanks.

Krakatau – Indonesia ; The Darwin VAAC reported that on 2 July ash plumes from Anak Krakatau rose to 1.5 km (5,000 ft) a.s.l. and drifted SW.

Rincon de la Vieja – Costa Rica : OVSICORI-UNA reported that an eruption at Rincón de la Vieja was recorded at 0838 on 1 July, though weather conditions prevented visual conformation of emissions. Small emissions were visible at 0937, 0940, and 1006 on 3 July. Small steam plumes were seen on 4 July, but too small to be recorded by the seismic network.

Sarychev Peak – Matua Island (Russia) : The Tokyo VAAC and SVERT reported that during 30 June-1 July ash plumes from Sarychev Peak rose to 3-5.5 km (10,000-18,000 ft) a.s.l. and drifted W, SE, and E based on satellite images. Plumes drifted as far as 25 km E on 1 July. The Alert Level remained at Yellow (the second lowest level on a four-COLOUR scale).

Suwanosejima – Ryukyu Islands (Japan) : JMA reported that 35 explosions at Suwanosejima’s Ontake Crater produced eruption plumes that rose as high as 2 km above the crater rim during 28 June-5 July. Large volcanic bombs were ejected 400 m from the crater and crater incandescence was visible nightly. Eruption sounds were heard in Toshima village (4 km SSW). The Alert Level remained at 3 and the public was warned to stay 2 km away from the crater.

Taal – Luzon (Philippines) : PHIVOLCS reported that anomalously high sulfur dioxide emissions were recorded at Taal, averaging 14,241 and 13,287 tonnes/day on 28 June and 1 July, respectively. Upwelling of hot volcanic fluids in the crater lake produced steam-and-gas plumes that rose as high as 3 km. Vog in the vicinity of the volcano persisted. At 1516 on 1 July a phreatomagmatic eruption generated a dark, 5-minute-long, Surtseyan plume that rose 1 km above the lake. The Alert Level was raised to 3 (on a scale of 0-5) at 1537. According to news articles and the Philippine Coast Guard, authorities began evacuating residents in Banyaga, Bilibinwang, Gulod, Boso-boso, and Lakeshore Bugaan East around 1700. Four additional short eruptions (less than two minutes) were recorded at 1826, 1921, 1941, and 2020, each ejecting material as high as 200 m. More phreatomagmatic eruptions on 2 July, at 1025, 1047, and 1101, jetted material 100 m above the lake. Sulfur dioxide emissions averaged 10,254 tonnes/day. Vigorous upwelling in the lake was visible in the afternoon, and steam-and-gas plumes that rose as high as 3 km drifted SW and NW. On 3 July steam-and-gas plumes rose 2.5-3 km and drifted SW and NW. Sulfur dioxide emissions averaged 14,699 tonnes/day, the highest ever measured from Taal. The high emissions and weather conditions again created vog in the area. A news article noted that about 10 children showed signs of illness from the vog. On 4 July PHIVOLCS issued a special advisory noting, again, a new record-breaking high of sulfur dioxide emissions at 22,628 tonnes/day. A total of 26 strong and very shallow low-frequency volcanic earthquakes below the E part of TVI had been recorded since the beginning of the day. Some of the earthquakes were accompanied by rumbling and weakly felt by fish cage caretakers off the NE shore. Lake upwelling persisted during 5-6 July with steam-and-gas plumes rising 2.5-3 km. Sulfur dioxide emissions averaged 5,299 tonnes/day on 5 July. The DROMIC report stated that 3,027 people were in 20 evacuation centers, and 2,759 people were in private residences by 6 July.
