Iceberg on Collision Course

The world’s most massive iceberg appears to be taking dead aim on a remote British territory in the South Atlantic, where it could have devastating consequences for the island’s wildlife.

Iceberg A-68A, roughly the size of Cyprus, broke off from Antarctica’s Larsen Ice Shelf in 2017 and is predicted to run aground in the shallow waters surrounding South Georgia in less than a month. Scientists from the British Antarctic Survey warn the massive chunk could block foraging routes for many thousands of the three penguin species that populate the island. This could threaten their chicks, as well as seal pups on the island, with starvation.

Global Temperature Extremes

The week’s hottest temperature was 108 degrees Fahrenheit (42.2 degrees Celsius) in Linguere, Senegal.

The week’s coldest temperature was minus 74.0 degrees Fahrenheit (minus 58.9 degrees Celsius) at Vostok, Antarctica.

Temperatures were tabulated from the more than 10,000 worldwide synoptic weather stations. The United Nations World Meteorological Organization sets the standards for weather observations, and provides a global telecommunications circuit for data distribution.

Wildfires

Wildfires – Brazil

The number of wildfires blackening tracts of Brazil’s Amazon rainforest surged last month, reaching a level 25% higher from January through October than in the same period of 2019.

And the 17,326 hot spots observed this October were more than double the number during the same month last year.

Brazil’s National Institute of Space Research also observed a record number of blazes farther south in the Pantanal, the world’s largest tropical wetlands, which extends across Brazil’s borders with Paraguay and Bolivia. The World Wildlife Fund and other environmental organizations blame the blazes on the policies of President Jair Bolsonaro, who promotes opening both regions of the country to logging and farming.

Roundup of Global Volcanic Activity – Ongoing Activity for the Week 28 October 2020 – 3 November 2020

Aira } Kyushu (Japan) – JMA reported that during 26 October-2 November incandescence from Minamidake Crater (at Aira Caldera’s Sakurajima volcano) was visible nightly. An eruption at 0620 on 30 October produced a plume that rose 1 km above the crater rim. The Alert Level remained at 3 (on a 5-level scale).

Dukono | Halmahera (Indonesia) – Based on satellite and wind model data and information from PVMBG the Darwin VAAC reported that during 28 October-3 November ash plumes from Dukono rose to 2.1 km (7,000 ft) a.s.l. and drifted in multiple directions. The Alert Level remained at 2 (on a scale of 1-4), and the public was warned to remain outside of the 2-km exclusion zone.

Ebeko | Paramushir Island (Russia) – Volcanologists in Severo-Kurilsk (Paramushir Island), about 7 km E of Ebeko, observed explosions during 22-23, 25-26, and 28-29 October that sent ash plumes up to 3.1 km (10,200 ft) a.s.l. and drifted W, NW, NE, and SE. The Aviation colour Code remained at Orange (the second highest level on a four-colour scale).

Fuego | Guatemala – INSIVUMEH reported that 2-14 explosions were recorded per hour during 27 October-3 November at Fuego, generating ash plumes as high as 1.1 km above the crater rim that drifted 10-25 km generally S, SW, and W. Shock waves rattled buildings within 12 km of the summit. Incandescent material ejected 100-300 m high caused block avalanches in the Ceniza (SSW), Seca (W), Trinidad (S), Taniluyá (SW), El Jute, Las Lajas (SE), and Honda drainages; avalanches sometimes reached vegetated areas. Ashfall was reported during 30 October-3 November in several areas downwind including Morelia (9 km SW), Panimaché I and II (8 km SW), Finca Palo Verde, La Rochela, Santa Sofía (12 km SW), Ceylon, El Zapote (10 km S), and Sangre de Cristo (8 km WSW).

Katmai | United States = On 31 October AVO reported that an ash cloud, resuspended by strong winds in the vicinity of Katmai and the Valley of Ten Thousand Smokes, drifted SE over the S part of Kodiak Island at an altitude up to 1.5 km (5,000 ft) a.s.l. The ash was originally deposited during the Novarupta eruption in 1912. The Volcano Alert Level remained at Normal and the Aviation colour Code remained at Green.

Pacaya | Guatemala – INSIVUMEH reported that Strombolian activity and lava effusion continued at Pacaya during 27 October-3 November. Explosions from the cone in Mackenney Crater ejected material as high as 250 m above the vent. Lava flows were 20 m and 1 km long on the NE and SW flanks, respectively. The lava flow on the NE flank was no longer active by 28 October, though parts of the SW-flank lava flow continued to advance through 3 November.

Santa Maria | Guatemala – INSIVUMEH reported that during 27 October-3 November lava extrusion at Santa María’s Santiaguito lava-dome complex generated block-and-ash flows that descended the W, SW, S, and SE flanks. Explosions generated ash plumes that rose as high as 900 m above the summit; ash plumes drifted 1 km SW during 27-28 and 30-31 October and as far as 10 km SW during 1-2 November. The lava dome was incandescent most nights.

Sheveluch | Central Kamchatka (Russia) – KVERT reported that a thermal anomaly over Sheveluch was identified in satellite images during 23-30 October. The Aviation colour Code remained at Orange (the second highest level on a four-colour scale).

Sinabung | Indonesia – PVMBG reported that each day during 27 October-2 November avalanches descended Sinabung’s E and SE flanks as far as 1 km. Pyroclastic flows traveled 1-2.5 km down the same flanks almost daily. According to a news article, an eruption at 0752 on 29 October produced an ash plume that rose 1.5 km and caused ashfall in areas within 10 km downwind, particularly in Kabanjahe (13 km SE) and Berastagi (13 km E). An eruptive event at 2358 on 2 November generated an ash plume that rose 1.5 km and drifted E. The Alert Level remained at 3 (on a scale of 1-4), with a general exclusion zone of 3 km and extensions to 5 km in the SE sector and 4 km in the NE sector.

Suwanosejima | Ryukyu Islands (Japan) – JMA reported nighttime incandescence and intermittent eruptive activity at Suwanosejima’s Ontake Crater during 23-30 October. Eight explosions were recorded; an explosion at 0204 on 24 October ejected bombs 300 m from the crater and an explosion at 1710 on 28 October produced an ash plume that rose 2 km above the crater rim. Ashfall was periodically reported in Toshima village (4 km SSW). The Alert Level remained at 2 (on a 5-level scale).

Telica | Nicaragua – INETER reported that a series of three explosions at Telica began at 1910 on 29 October and ended at 2137. The events ejected rock fragments onto the flanks and produced gas-and-ash plumes that rose as high as 1 km above the crater rim and drifted W. Ashfall was reported in areas downwind including the communities of El Bosque, Jacinto Baca (15 km WSW), Filiberto Morales (15 km WSW), Carlos Huete, Linda Vista, Divino Niño (31 km W). Three explosions produced gas-and-ash plumes that rose 250-600 m above the rim during 30-31 October. A minor amount of ash fell on the flanks.
