Australia – Flash flooding has hit North Queensland, drenched in nearly 400mm of rain which fell incredibly fast. Sandbags are out, rivers are swollen and Townsville is on edge, bracing for a second night of monsoonal downpours. Homes have been destroyed and trees stripped of leaves by a severe storm that tore through parts of South Australia’s Eyre Peninsula just days after flooding rains. The storm on Wednesday evening caused the most damage in an area of the central Eyre Peninsula around Cummins, Yeelanna and Kapinnie. The Bureau of Meteorology recorded almost 50 millimetres of rainfall at the Port Lincoln airport, to the south, in about five hours on Wednesday night.

Environment

A Toxic World

A new study suggests chemical pollution has become so pervasive that it has pushed Earth outside the relatively stable environment of the past 10,000 years.

Beyond the widespread use of plastics, researchers say they are also highly concerned about 350,000 synthetic chemicals, including pesticides, industrial compounds and antibiotics. “There has been a fifty-fold increase in the production of chemicals since 1950 and this is projected to triple again by 2050,” said research team member Patricia Villarrubia-Gómez of Sweden’s Stockholm Resilience Center. “Shifting to a circular economy is really important. That means changing materials and products so they can be reused, not wasted,” Villarrubia-Gómez added.

Wildlife

Pollination Stress

Bees, butterflies and other pollinators exposed to common air pollution are significantly impaired in their ability to sniff out the plants that depend upon them, according to new field research.

British scientists say the pollution, combined with land use changes, are also responsible for an up to 70% drop in the number of pollinating insects. Writing in the journal Environmental Pollution, the team said they exposed a test field to levels of pollution commonly found near highways and observed up to 90% fewer flower visits by the pollinators. They believe the pollution changes the scents of flowers, making them harder to find.

Global Temperature Extremes

The week’s hottest temperature was 46.1 degrees Celsius (115 degrees F) at Robertson, South Africa.

The week’s coldest temperature was minus 54.4 degrees Celsius (-66 degrees F) at Oimyakon, Siberia.

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 – South Africa

South Africa’s Western Cape Province on Thursday said over 10 million South African rands have been spent on 14 major wildfires and dozens of smaller fires in the province during this summer’s fire season. The most prominent fire affected 5,372 hectares of land and most of the major wildfires happened last week throughout the province.

Record Blast

The explosive force of the massive volcanic blast off Tonga earlier this month appears to have far exceeded that of the biggest nuclear detonation ever conducted. The global network of 53 seismic, underwater acoustic and surface infrasound detectors used by the Comprehensive Nuclear-Test Ban Treaty Organization measured the low-frequency boom, which was heard as far away as Alaska, 6,200 miles to the north. Those measurements show it was more powerful than the Soviet Union’s 1961 Tsar Bomba.

Roundup of Global Volcanic Activity – Ongoing Activity for the week 19 January – 25 January 2022

Aira – Kyushu (Japan) : JMA reported that incandescence from Minamidake Crater (at Aira Caldera’s Sakurajima volcano) was visible at night during 17-24 January. Sulfur dioxide emissions were somewhat high on 17 January at 1,000 tons per day. Two explosions on 18 January produced ash plumes that rose as high as 2 km above the crater rim and ejected ballistics 1-1.3 km away from the crater.

Great Sitkin – Andreanof Islands (USA) : AVO reported that slow lava effusion at Great Sitkin likely continued during 18-25 January, and seismicity remained at very low levels. Elevated surface temperatures were identified in satellite data during 19-22 January.

Kanlaon – Philippines : PHIVOLCS issued a special notice for Kanlaon on 21 January, noting that a total of 18 volcanic earthquakes were recorded in the past day. Four of those events were classified as shallow “tornillo” signals indicating gas movement along shallow fractures in the upper part of the volcano. Ground deformation data from continuous GPS and tilt measurements indicated slight inflation of the volcano since mid-October 2021. The seismic activity and ground deformation was likely caused by shallow hydrothermal processes and could generate phreatic events.

Karymsky – Eastern Kamchatka (Russia) : KVERT reported that on 15 and 17 January explosions at Karymsky produced ash plumes that rose as high as 7 km (23,000 ft) a.s.l. and drifted 172 km W. A thermal anomaly was visible in satellite images on 16 January.

Kilauea – Hawaiian Islands (USA) : HVO reported that lava effusion resumed at the vent in the lower W wall of Kilauea’s Halema`uma`u Crater at around 1045 on 18 January. By 1630 the level of the lava lake had risen 12 m, slightly surpassing the high recorded on 12 January, but then slightly dropped within 30 minutes. The W part of the lake was active. The sulfur dioxide emission rate was about 2,100 tonnes per day the next day. During 19-20 January lava oozed out along the SE and NW margins of the lake, though by the afternoon of the 20th the active portion of the lake was small and located N of the cone. Just after 0400 on 21 January the effusion rate increased and the W half of the lake was again active. Notable overflows of lava later that evening sent flows NW, SW, and SE. The lake level dropped 9 m during the morning of 22 January, and again only a small portion of the lake was active. Lava oozed out from the E and NW lake margins. Lava input into the small lake became intermittent starting at around 1500 on 23 January, though lava oozed out along the NW and S margins. The effusion rate increased at 0552 on 25 January and lava flowed W and N along the crater margins. By 0820 the lava lake had risen 11 m.

Merapi – Central Java (Indonesia) : BPPTKG reported no significant morphological changes at Merapi’s lava domes, located just below the SW rim and in the summit crater, during 14-20 January. Seismicity remained at high levels. As many as 91 lava avalanches traveled a maximum of 2 km SW down the Bebeng drainage, and one pyroclastic flow traveled 2 km SW.

Pavlof – United States : AVO reported that the eruption at Pavlof was ongoing during 18-25 January, with periods of elevated tremor. Small daily explosions were recorded on local and regional infrasound sensors during 18-22 January. A satellite image from 19 January showed that the lava flow on the E flank was 1.3 km long, and a lahar on the same flank was 4.4 km long. Elevated surface temperatures consistent with the active lava flow persisted through 25 January.

Reventador – Ecuador : IG reported that a high level of activity continued at Reventador during 18-25 January. Gas-and-ash plumes, often observed multiple times a day with the webcam or reported by the Washington VAAC, sometimes rose higher than 1 km above the summit crater and drifted mainly NW, W, and SW. Crater incandescence was visible at night during 19-20 January. Cloudy weather sometimes prevented visual observation during 21-23 January. Lava flows on the E and NE flanks were visible during 23-25 January and continued to advance.

Rincon de la Vieja – Costa Rica : OVSICORI-UNA reported that two eruptions were recorded at Rincón de la Vieja, at 2227 on 20 January and 0225 on 23 January, though weather conditions prevented visual confirmation of plumes. Each event was 1-2 minutes long. At 1139 on 25 January an eruption produced a plume that rose 500-1,000 m.

Santa Maria – Guatemala : INSIVUMEH reported that the eruption at Santa María’s Santiaguito lava-dome complex continued during 19-25 January. Crater incandescence was visible at night. Avalanches generated by both lava effusion at the W and SW part of Caliente dome and collapsing material descended the W, SW, and SE flanks, often reaching the base of the dome. Periodically the avalanches produced curtains of ash along their paths that dissipated near the volcano. Almost daily explosions produced ash plumes that rose 700-900 m above the summit and drifted 10-15 km W and SW; ashfall was reported in areas downwind during 21-23 January including in San Marcos Palajunoj (8 km SW) and Loma Linda (6 km WSW). Lava flows on the W and SW flanks were 500 and 700 m long, respectively.

Semeru – Eastern Java (Indonesia) : PVMBG reported that an eruptive event at 0911 on 21 January produced an ash plume that rose 200 m above Semeru’s summit and drifted N. A second event, recorded at 0741 on 25 January, generated an ash plume that rose 200 m and drifted SE. The Alert Level remained at 3 (on a scale of 1-4). The public was warned to stay at least 500 m away from Kobokan drainages within 17 km of the summit, along with other drainages originating on Semeru, including the Bang, Kembar, and Sat, due to lahar, avalanche, and pyroclastic flow hazards.

Semisopochnoi – Aleutian Islands (USA) : AVO reported that low-level eruptive activity at Semisopochnoi’s North Cerberus cone continued during 18-25 January. Seismicity was elevated, characterized by periods of tremor and low-frequency earthquakes. Steam emissions were periodically visible in webcam images during 18-19 January and minor explosions were recorded by local seismic and infrasound sensors on 19 January. Steam and low-level ash emissions were visible in webcam and satellite images during 20-25 January. Daily explosions were recorded during 21-25 January, and elevated surface temperatures were identified in satellite data during 22-23 January.

Sheveluch – Central Kamchatka (Russia) : KVERT reported that a thermal anomaly over Sheveluch was identified in satellite images during 14-21 January. Intense steam-and-gas emissions with ash were visible during 15-16 January; plumes rose as high as 6.5 km (21,300 ft) a.s.l. and drifted 77 km W.

Stromboli – Aeolian Islands (Italy) : INGV reported that during 17-23 January activity at Stromboli was characterized by ongoing explosions from five vents in Area N (North Crater area) and two vents in Area C-S (South-Central Crater area). Explosions from Area N vents (N1 and N2) averaged 7-14 events per hour; explosions from two vents in the N1 vent ejected lapilli and bombs 80 m high and those at three N2 vents ejected material less than 80 m high. Spattering at N2 had been intense the week before, depositing material onto the upper part of the Sciara del Fuoco that then rolled down the flank to the coastline on 16 January; spattering was again intense on 22 January. No explosions occurred at the S1 and C vents in Area C-S; explosions at the two S2 vents occurred at a rate of 3-4 per hour and ejected coarse material mixed with fine ash higher than 80 m.

Suwanosejima – Ryukyu Islands (Japan) : JMA reported that incandescence at Suwanosejima’s Ontake Crater was visible nightly during 17-24 January. There were 46 explosions recorded, producing ash plumes that rose at least 1.8 km above the crater rim and ejected material up to 1 km away from the crater. Rumbling sounds and ashfall were reported in Toshima village (3.5 km SSW).

Taal – Luzon (Philippines) : PHIVOLCS reported that unrest at Taal continued during 18-25 January. Low-level background tremor persisted; one volcanic earthquake was recorded during 18-19 January. Hot volcanic fluids were upwelling in the crater lake, and daily gas-and-steam plumes rose 0.6-2.4 km above the lake and drifted SW. Sulfur dioxide emissions continued to be elevated, averaging 10,986 and 11,228 tonnes/day on 20 and 23 January, respectively.

Turrialba – Costa Rica : OVSICORI-UNA reported that periodic eruptive events, lasting 1-2 minutes each, were recorded at Turrialba’s West Crater during 19-24 January. At 0546 on 19 January an eruption produced an ash plume that rose 200 m above the summit and drifted W. A small eruption at 1052 generated a plume that rose 50 m and drifted NW. At 0706 on 24 January an event generated a plume that rose 100 m and drifted SW. Two points of incandescence on the internal SW crater wall were also visible.

Roundup of Global Volcanic Activity – New Activity for the week 19 January – 25 January 2022

Ambrym – Vanuatu : On 25 January the Vanuatu Meteorology and Geo-Hazards Department (VMGD) raised the Alert Level for Ambrym to 2 (on a scale of 0-5) due to a significant increase in activity beginning at around 0400. Steam emissions rose from Marum Crater, and at 0515 a steam, gas, and ash plume rose from Benbow Crater. Satellite data recorded increased sulfur dioxide emissions from Benbow, and residents of Ambrym and surrounding islands reported seeing incandescence from crater overnight.

Hunga Tonga-Hunga Ha’apai – Tonga Islands : No additional eruptive events were detected at Hunga Tonga-Hunga Ha’apai after the large and explosive eruption on 15 January. The gas, steam, and ash plume produced during that eruption rose into the stratosphere and drifted W. Based on volcanic ash advisories issued by the Wellington VAAC and then by the Darwin VAAC, the horizontal extent of the plume grew from 18,000 square kilometers at 1739 on 15 January to 12 million square kilometers by 1300 on 19 January. The plume narrowed and lengthened along an E-W axis, moving W over Australia. The Aviation Color Code was lowered to Green on 19 January. According to the Darwin VAAC the plume continued to drift W at altitudes between 12.8 and 19.2 km (42,000 and 63,000 ft) a.s.l. during 19-22 January; the ash was diffuse and difficult to distinguish from meteorological clouds, though the sulfur dioxide signal was stronger. By 22 January the leading-edge of the plume had reached the E coast of Africa. By 2150 the Darwin VAAC noted that ash was no longer detectable. Tsunami waves generated by the 15 January eruption caused an oil spill near at the La Pampilla refinery along Peru’s coast, affecting a 38-km-stretch of beach from Ventanilla to Peralvillo Beach in Chancay, according to Peru’s Agency for Environmental Assessment and Enforcement (OEFA). An estimated 6,000 barrels of oil were spilled, significantly impacting an estimated 180 hectares of beach, almost 715 hectares of ocean, and local fisherman. In a media release on 21 January, the Government of Tonga reported that ashfall and tsunami had damaged all islands. International humanitarian aid had reached the islands the day before, five days after the eruption ceased. Inter-island and international communication remained challenging though was partially restored; a relief flight from New Zealand brought telecommunication equipment and a repair vessel was en-route to the damaged seafloor fiber-optic cable. Floating debris, likely including pumice, hindered sea transportation. Domestic flights remained suspended, though international flights carrying relief supplies were able to land and aerial surveys of damage were conducted. According to a social media post from 23 January residents swept ash off of a Salote Pilolevu Airport runway in Ha’apai. News reports shared stories of survivors and showed images of damage around the islands. Dozens of earthquakes, M 4.5-5, were centered in the vicinity of the volcano after the eruption, at least through 24 January. The type of earthquake signal was unknown, though they likely represented post-eruption movement along existing faults and not magma movement.

Wolf – Isla Isabela (Ecuador) : IG reported that the eruption at Wolf continued during 18-25 January. Daily thermal alerts counts were in the hundreds, centered over the advancing lava flows on the SE flank. Diffuse gas emissions were visible drifting SW during 18-20 January. Activity levels were stable during the beginning of the week then began to trend downward by 21 January.

Putting a Cost on Climate Change

Led by the deadly and costly Hurricane Ida and massive flooding in Europe, the world racked up $329 billion in economic losses linked to severe weather last year, and only 38% of that bill was covered by insurance. Total economic losses tallied $343 billion, Aon said, $329 billion of which resulted from weather and climate-related events such as hurricanes, flooding, wildfires, tsunamis and drought. That left 2021 as the third costliest year on record after adjusting for inflation.

“There’s no question that the finger prints of climate change are already here today, more intense weather, impacting more things in harm’s way,” Steve Bowen, meteorologist and head of catastrophe insight at Aon.
