Malaysia – Severe flooding swept through parts of Sabah State in Malaysia after heavy rain on 15 September. The rain is also thought to have been the cause of a landslide where 3 people died. The streets of the state capital Kota Kinabalu were under flood water over 1.5 metres deep. Meanwhile the heavy rain is thought to have been the cause of a landslide in Penampang District which destroyed at least 1 building. A mother and 2 young children tragically lost their lives in the incident. Three other victims including two children survived.


Slaughter of more than 1,400 dolphins in the Faroe Islands

Hunters in the Faroe Islands riding speed boats and jet skis ambushed and slaughtered a super-pod of more than 1,400 white-sided dolphins on Sunday (Sept. 12), leading to outcry from conservationists and even some supporters of the archipelago’s centuries-old tradition of killing the marine animals for food. The dolphins’ bloody, lacerated corpses have been left lined up on the beach following the killings.

The scale of the slaughter drew outrage from conservationists, Faroese natives and pro-hunting parties alike. The Sea Shepherd Conservation Society described the killings as a “massacre.”

Bug Food Anyone?

Finnish researchers say Europe can reduce global warming associated with its food consumption by switching, at least in part, to edible insects, such as crickets, flies and worms.

The team from the University of Helsinki and LUT University, Finland, proposes eating them fresh or drying and processing them into flour for bread and pasta. It adds that directly eating the insects will contribute less to climate change than using them for livestock feed instead of soy.

The expanding use of soy in animal feed has led to rampant deforestation around the world to meet the demand.

Global Warming

Oil Should Remain in the Ground

A new study says that oil and gas production around the world must fall by 3% each year, with 58% of known petroleum reserves remaining in the ground, to hold global heating to the 1.5 degrees Celsius goal in the Paris Agreement.

“There’s a good likelihood the rates of decline are going to have to be even larger, and the total amount of carbon that’s going to stay in the ground is also going to be larger,” said James Price at University College London, involved in the analysis.

While some oil companies have cut their plans for future oil and gas extraction as they transition to low-carbon energy, Price says the outlook is bleak for cooperation from countries that rely on revenue from oil and gas.


Global Temperature Extremes

The week’s hottest temperature was 45.5 degrees Celsius at Adrar, Algeria.

The week’s coldest temperature was minus 70.5 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.

Roundup of Global Volcanic Activity – Ongoing Activity for the Week 8 September – 14 September 2021

Aira – Kyushu (Japan) : JMA reported that incandescence from Minamidake Crater (at Aira Caldera’s Sakurajima volcano) was visible at night during 6-10 September. Deformation data showed inflation beginning at around 0300 on 13 September.

Cerro Hudson – Chile : SERNAGEOMIN lowered the Alert Level for Cerro Hudson to Green (the lowest level on a four-color scale) on 7 September, based on decreased activity. Neither morphological changes nor thermal anomalies were visible in satellite images or webcam views during 16-31 August. Seismicity remained low and sulfur dioxide emissions were not recorded.

Ebeko – Paramushir Island (Russia) : According to volcanologists in Severo-Kurilsk (Paramushir Island), about 7 km E of Ebeko, explosions during 4 and 6-8 September produced ash plumes that rose as high as 2 km (6,600 ft) a.s.l. and drifted N, S, and E. Ash fell in Severo-Kurilsk on 6 and 8 September.

Great Sitkin – Andreanof Islands (USA) : AVO reported that lava effusion continued at Great Sitkin during 7-14 September, though weather clouds often prevented webcam and satellite views. Seismicity remained elevated and was characterized by small earthquakes consistent with lava effusion. A radar image from 9 September indicated that the lava dome had grown to 1,100 m E to W and 860 m N to S, and was 25-30 m thick. Lava began to advance though a gap in the S rim of the summit crater. Elevated surface temperatures were visible in satellite data on 14 September.

Grimsvotn – Iceland : Icelandic Meteorological Office (IMO) reported that the jökulhlaup from the eastern and western parts of Grímsvötn’s caldera that began on 1 September had decreased during 8-10 September. IMO warned of continuing flood conditions in the downstream parts of the Skaftá river.

Ibu – Halmahera (Indonesia) : PVMBG reported that during 7-12 September gray-and-white ash plumes from Ibu rose 200-800 m above the summit and drifted N and W.

Karymsky – Eastern Kamchatka (Russia) : KVERT reported that a thermal anomaly over Karymsky was identified in satellite images during 3-10 September. Ash plumes rose 4 km (13,100 ft) a.s.l. and drifted 165 km E during 2-6 and 9 September.

Krysuvik-Trolladyngja – Iceland : The fissure eruption in the W part of the Krýsuvík-Trölladyngja volcanic system, close to Fagradalsfjall on the Reykjanes Peninsula, had paused for several days. The Institute of Earth Sciences reported that based on aerial photography acquired on 9 September, during the pause, the area of the flow field had grown to 4.6 square kilometers, and the total volume erupted was 143 million cubic meters. The crater floor was visible and was at least 70 m deep, with a deeper cavity or drainage sometimes visible. Lava visibly returned on 11 September; RSAM values increased and low lava fountains emerged from a few areas on the flow field to the W of the main crater. Lava also returned to the main vent. Lava fountains from the main crater were visible for periods of 5-10 minutes on 13 September and lava advanced in multiple directions. Lava flowed N on 14 September. By 15 September lava quickly advanced S, flowing past the earthen barriers constructed at the S end of Geldingadalur valley, and turning E into the Nàtthagi valley. The Aviation Color Code remained at Orange due to the lack of ash and tephra emissions, though IMO warned of the potential for lapilli and scoria fallout within a 650 m radius of the active vent. Authorities also warned of gas emission hazards.

Langila – New Britain (Papua New Guinea) : Based on analyses of satellite imagery and wind model data, the Darwin VAAC reported that during 11-12 September ash plumes from Langila rose to 2.1-2.4 km (7,000-8,000 ft) a.s.l. and drifted W. A thermal anomaly at the summit was identified in satellite data.

Lewotolok – Lembata Island (Indonesia) : PVMBG reported that the eruption at Lewotolok continued during 7-14 September. White-and-gray plumes rose as high as 700 m above the summit and drifted NWW, SW, and S.

Merapi – Central Java (Indonesia) : BPPTKG reported that both of Merapi’s two lava domes, situated just below the SW rim and in the summit crater, continued to grow during 3-9 September. The SW dome grew 5 m taller and had an estimated volume of 1.55 million cubic meters and the summit lava dome grew 1 m wider and had an estimated volume of 2.85 million cubic meters. One pyroclastic flow traveled 2 km down the SW flank and as many as 129 lava avalanches traveled a maximum of 2 km SW. According to the Darwin VAAC ash plumes rose 3 km (10,000 ft) a.s.l. and drifted E on 9 September, based on satellite and webcam views.

Nevados de Chillan – Chile : SERNAGEOMIN reported continuing explosive and effusive activity at Nevados de Chillán’s Nicanor Crater during 16-31 August, though weather conditions often prevented visual confirmation. Explosions generated ash plumes that rose as high as 1.1 km above the crater rim and were denser towards the end of August. Crater incandescence was sometimes visible at night, and though not intense, it brightened during explosive periods. The L5 and L6 lava flows continued to advance, though at a very low rate, averaging 1 m/h for L5. The L5 lava flow was 1,380 m long and L6 was 850 m long based on satellite images, measured from the rim of Nicanor Crater to the distal end of the flows. A decrease in thermal anomalies over the flows identified in satellite images suggested that the flows were cooling. The average temperature was 73 degrees Celsius with a maximum of 100 degrees for L5 and an average of 79 degrees Celsius with a maximum of 100 degrees for L6. Temperatures at the vents at Nicanor Crater averaged 115 degrees Celsius and were as high as 252 degrees during explosive phases. Sulfur dioxide emissions measured from local DOAS stations abruptly decreased and remained low. There was a total of five thermal anomalies, all with low radiance values. On 29 August pyroclastic flows traveled 560 m NE and collapses of L5’s middle and distal parts of the flow were observed.

Pavlof – United States : AVO reported that seismicity at Pavlof continued at low levels during 7-14 September and was interspersed with periods of more energetic tremor. Although weather clouds often obscured views, a series of four very minor ash emissions were visible in webcam images for a period of five hours on 10 September. The explosions produced minor and diffuse ash emissions that rose from a vent on the E flank and dissipated within minutes. A small explosion was recorded on 12 September and on 13 September, though cloud cover prevented visual confirmation of both events.

Semisopochnoi – Aleutian Islands (USA) : AVO reported that eruptive activity at Semisopochnoi’s North Cerberus crater continued during 7-14 September. Seismicity was elevated and characterized by periods of continuous tremor. Short-lived explosions lasting several minutes were detected daily in infrasound data. Small ash clouds from the explosions rose 3-4.6 km (10,000-15,000 ft) and dissipated within two hours. Sulfur dioxide emissions were detected in satellite images at altitudes less than 3 km (10,000 ft) a.s.l., sometimes extending downwind for hundreds of kilometers. During 7-9 September periods of lower-altitude ash emissions interspersed with voluminous steam plumes were observed in web camera images moving horizontally by the wind and rising no higher than 1.5 km (5,000 ft) a.s.l.

Sheveluch – Central Kamchatka (Russia) : KVERT reported that a bright thermal anomaly over Sheveluch was identified in satellite images during 3-10 September. The Kamchatka Branch of Geophysical Services (KBGS; Russian Academy of Sciences) Kamchatka volcano station reported that tourists visiting the volcano on 8 September experienced ashfall; weather conditions prevented views of summit. The next day they saw a small pyroclastic flow and that night saw crater incandescence and small incandescent avalanches traveling SE.

Suwanosejima – Ryukyu Islands (Japan) : JMA reported that four explosions at Suwanosejima’s Ontake Crater produced eruption plumes that rose as high as 3.3 km above the crater rim during 3-10 September. Large volcanic bombs were ejected 500 m from the crater. Crater incandescence was visible nightly.

Taal – Luzon (Philippines) : PHIVOLCS reported that gas-and-steam plumes from Taal rose as high as 2.5 km above the lake during 8-14 September and drifted NE, SE, S, and SW. Sulfur dioxide emissions were 5,246-11,840 tonnes/day during 9-10 and 12-13 September.
