Roundup of Global Volcanic Activity – Ongoing Activity for the week 16 November – 22 November 2022

Aira – Kyushu (Japan) : JMA reported ongoing eruptive activity at Minamidake Crater (at Aira Caldera’s Sakurajima volcano) and nighttime crater incandescence during 14-21 November. Sulfur dioxide emissions were slightly high on 14 November at 1,100 tons per day. Six eruptive events and four explosions (during 15-16 and 20-21 November) produced volcanic plumes that rose as high as 2.2 km above the crater rim and ejected large blocks as far as 900 m from the vent.

Alaid – Kuril Islands (Russia) : Activity has been gradually decreasing since the last ash plume was recorded on 26 October. A thermal anomaly continued to periodically be identified in satellite images when weather conditions permitted views, though the temperature of the thermal anomaly began decreasing on 29 October.

Ebeko – Paramushir Island (Russia) : KVERT reported that moderate activity at Ebeko was ongoing during 10-17 November. According to volcanologists in Severo-Kurilsk (Paramushir Island, about 7 km E) explosions during 12-13 and 16 November generated ash plumes that rose to 2.6 km (8,500 ft) a.s.l. and drifted in eastern directions. Ash fell in Severo-Kurilsk on 16 November. A thermal anomaly was identified in satellite images on 16 November; weather clouds prevented satellite views on the other days of the week.

Great Sitkin – Andreanof Islands (USA) : AVO reported that slow lava effusion continued at Great Sitkin during 15-22 November and the flow field continued to grow. Flow lobes extended about 600 m E of the vent and about 430 m S. Seismicity was low, with the occasional detection of low-frequency earthquakes. Satellite and webcam images were often cloudy through the week.

Karymsky – Eastern Kamchatka (Russia) : KVERT reported that a thermal anomaly at Karymsky was identified in satellite images on 13 and 15-17 November. Gas-and-steam emissions persisted.

Kerinci – Central Sumatra : PVMBG reported that brown ash plumes from Kerinci, often dense, rose as high as 150 m above the summit and drifted NE, E, and SE during 16-18 and 20-21 November. Weather clouds prevented visual observations during 18-20 November.

Kilauea – Hawaiian Islands (USA) : HVO reported that lava continued to effuse from a vent in the lower W wall of Kilauea’s Halema`uma`u Crater during 16-22 November entering the lava lake and flowing onto the crater floor. The active part of the lake remained at a steady level all week.

Manam – Northeast of New Guinea : The Darwin VAAC reported that on 20 November ash plumes from Manam rose to 1.8 km (6,000 ft) and drifted NW based on satellite images.

Pavlof – Alaska Peninsula, Alaska: AVO reported that a minor eruption at a vent on Pavlof’s upper E flank was ongoing during 16-22 November and nearly continuous seismic tremor was recorded. Almost daily elevated surface temperatures were identified in satellite images; weather clouds prevented views during 21-22 November. Webcam images showed occasional minor steaming and minor ash emissions in addition to a recent mass flow and ash deposits on the upper to lower flanks visible during 15-16 November, and incandescence at the vent during 16-17 November possibly associated with lava spattering or fountaining.

Semeru – Eastern Java : PVMBG reported that the eruption at Semeru continued during 16-22 November. White gas-and-steam plumes rose 100-200 m above the summit and drifted in various directions during 16-17 November. Emissions were not visible during 18-20 November, though weather conditions sometimes prevented visual observations. At 0608 on 21 November a white-to-gray ash plume rose around 400 m and drifted E. On 22 November white-to-gray ash plumes rose 300 m and drifted S at 0405, 600 m at 0503, and 800 m at 1541.

Semisopochnoi – Aleutian Islands (USA) : AVO reported ongoing low-level seismicity at Semisopochnoi characterized by intermittent seismic tremor and occasional low-frequency earthquakes during 16-22 November. Satellite and webcam views were mostly obscured by weather clouds, though during clear views continuous gas-and-steam emissions from the N crater of Mount Cerberus were visible.

Sheveluch – Central Kamchatka (Russia) : KVERT reported that the ongoing eruption at Sheveluch during 11-17 November was generally characterized by explosions, hot avalanches, lava-dome extrusion, and strong fumarolic activity. A daily thermal anomaly was identified in satellite images. Collapses generated hot avalanches and ash plumes that drifted 85 km ENE during 13-14, and 16-17 November.

Suwanosejima – Ryukyu Islands (Japan) : JMA reported that the eruption at Suwanosejima’s Ontake Crater continued during 14-21 November and crater incandescence was visible nightly. Eruption plumes generally rose 600 m above the crater rim and blended into weather clouds. An explosion at 0251 on 15 November ejected blocks 500 m from the vent and produced an eruption plume that rose 2.3 km above the crater rim and drifted SE.

Saudi Arabia – Two people have died in floods that swept across Saudi Arabia’s coastal city of Jeddah on Thursday due to record rain levels. The floods have also caused flight delays at King Abdulaziz International Airport, school closures and blocked the road to Mecca, Islam’s holiest city. According to Saudi Arabia’s National Center for Meteorology, the rainfall in Jeddah’s southern area between 8am and 2pm on Thursday, which stood at 179 millimeters, was the “highest” ever recorded.

Portugal – Authorities in the municipality of Esposende in Braga District of northern Portugal report that 2 people have died after a landslide following heavy rainfall. A landslide and large rocks destroyed part of a single-family home in Palmeira de Faro in Esposende early on 23 November 2022. Two people died and 4 people were rescued unharmed.

Wildlife

Extinct Bird Rediscovered

An exotic bird thought to have gone extinct 140 years ago has been “rediscovered” by researchers on a tiny island off Papua New Guinea. The black-naped pheasant pigeon was spotted in images from remote cameras on Fergusson Island.

“It is the kind of moment you dream about your entire life as a conservationist and birdwatcher,” said expedition co-lead John Mittermeier. The team initially had help from one local who reported seeing the pheasant-pigeon several times in an area with steep ridges and valleys, and described hearing the bird’s distinctive calls.

Shark Protection

Representatives attending the world’s largest wildlife summit have voted for the first time to regulate the hunting of sharks, which kills millions of the fish each year to meet the huge demand for shark fin soup.

The 186-nation Convention on International Trade in Endangered Species of Wild Fauna and Flora, or CITES, signed an agreement to regulate the commercial fishing of 54 shark species, including tiger, bull and blue sharks, which are the most targeted for the fin trade.

Environment

Reproduction in Crisis

Drops in sperm counts of more than 60% in North American, European and Australian men between 1973 and 2018 means humans could face a reproductive crisis.

Writing in the journal Human Reproduction Update, researchers warn the decline is accelerating and that declines were also occurring in Central and South America, Africa and Asia. It’s unclear what might be behind the apparent trend, but exposure to endocrine-disrupting chemicals or other environmental factors could be factors.

Environment

Global Temperature Extremes

The week’s hottest temperature was 44.0 degrees Celsius (111 degrees F) at Rivadavia, Salta, Argentina.

The week’s coldest temperature was minus 51.0 degrees Celsius (-60 degrees F) 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 – New Activity for the week 16 November – 22 November 2022

Ahyi – Mariana Islands (USA) : On 18 November the USGS reported that hydroacoustic and seismic signals suggestive of underwater eruptive activity at Ahyi Seamount had declined over the past week. No other signs of volcanic unrest were detected at the seamount.

Bezymianny – Central Kamchatka (Russia) : KVERT reported that during 11-17 November a daily thermal anomaly over Bezymianny was identified in satellite images. Gas-and-steam emissions were visible and occasional collapses from the growing lava dome produced avalanches of hot material.

Copahue – Central Chile-Argentina : Based on information from Observatorio Argentino de Vigilancia Volcánica (OAVV), SERNAGEOMIN and SEGEMAR reported a minor increase of activity at Copahue. RSAM values based on volcanic tremor began to increase on 13 November. Weather conditions prevented views of the volcano during 13-14 November. On 15 November an increase in the magnitudes of tremor signals was accompanied by increased and denser gas emissions rising 200 m above El Agrio Crater. The emissions, seen in webcam images, were mostly whitish and contained particulate material.

Klyuchevskoy – Central Kamchatka (Russia) : KVERT reported that a thermal anomaly over Klyuchevskoy was first identified on 13 November and was visible daily through 20 November. An explosive Strombolian eruption began at 2330 local time on 17 November, the same day that the thermal anomaly intensified. Gas-and-steam plumes drifted SE. The Strombolian eruption and gas emissions persisted.

San Miguel – Eastern El Salvador : MARN reported that an eruption at San Miguel’s central crater began on 15 November, and by 1100 on 20 November a total of 62 phreatic explosions had been recorded, averaging 10 per day. An additional 24 explosions were recorded from 1100 on 20 November to 1100 on 21 November and 12 more were recorded between 1100 and 1100 during 21-22 November. Explosions generated gas, ash, and steam plumes that generally rose around 500 m above the crater rim, though at 1336 on 18 November and 1206 on 19 November eruption plumes rose as high as 1.1 km. Some of the events were accompanied by crater incandescence during 15-20 November. Sulfur dioxide emissions generally averaged 100-170 tons per day, below the baseline of 300 tons per day. Specific measurements during explosive events revealed that the emissions were sometimes higher; 1,200 tons per day was measured on 19 November during one of the largest explosions, and 378 tons per days was measured during an explosion on 21 November. Seismicity was characterized by volcano-tectonic events, long-period events, and tremor. Deformation data showed no significant changes.

Takawangha – Andreanof Islands (USA) : The number of small earthquakes detected near the volcano had increased during from 16 November and intensified during 17-18 November. The earthquakes were located at depths of 3-6 km below sea level with the largest magnitudes between 2 and 3. The seismicity possibly indicated magma movement at depth. The intensity of the seismicity was variable during 19-22 November.

Villarrica – Central Chile : During an overflight of Villarrica on 19 November, SERNAGEOMIN scientists observed a cone on the crater floor with an incandescent vent at its center, containing a lava lake. Deposits of ejected material were seen on the flanks. That same day a 75-minute-long series of volcano-tectonic earthquakes began at 1940. There was a total of 21 events located 7.8 km ESE of the crater. The largest event, a M 1.6, occurred at 2007 at a depth of 2.5 km based on data collection and analysis of Red Nacional de Vigilancia Volcánica (RNVV) and Observatorio Volcanológico de los Andes del Sur (OVDAS), respectively.

Italy – A wave of severe weather swept across Italy from 22 November 2022, including strong winds, high waves, storm surge and heavy rain. Emergency services carried out 2,500 interventions in 8 regions. Local media said the severe weather was brought by Storm Denise, which also affected the French island of Corsica. Many of the interventions were in response to damage caused by strong winds, including roofs ripped off buildings, and downed trees, branches and power lines. Vigili del Fuoco reported winds of more than 100 km/h in Trieste in Friuli Venezia Giulia Region. Stormy weather and roughs seas also affected areas in Sicily where ferry services were disrupted from the port at Milazzo.

Panama – Civil Protection authorities in Panama report that two people have died after heavy rain triggered a landslide in Colón Province. Meanwhile flooding continues to affect communities in Los Santos and Herrera Provinces where dozens of homes have been damaged. Heavy rain since the start of November has caused flooding and landslides in several provinces of the country. The rain is expected to continue until at least the end of the month.

Guyana – Torrential rain flooded large parts of Georgetown yesterday afternoon underlining the vulnerability of the capital to inundation in the context of climate change and a key pump went down after it came into a contact with a piece of wood. Although all other pumps and sluices were operable, the four inches of rain that drenched the capital left knee-high floods as kokers could not be opened due to the high tide.

Australia – Flooding in New South Wales continues with residents in Euabalong having been ordered to evacuate now as the Lachlan River rises toward a record peak. Moulamein residents are preparing to be isolated for weeks while Condobolin residents hope the worst of the crisis has passed.

Venice Flooding

Tourists know to beware of the ‘acqua alta’ in the fall and winter. The higher-than-normal high tides from the Adriatic Sea rush into the Venice Lagoon and over ancient squares, into ground floors and leave priceless monuments submerged. City leaders turned the tide and placed temporary glass barriers to protect the 900-year-old St. Mark’s Basilica.

A four-foot glass wall now surrounds the church to block priceless mosaics, marble, art, historical objects and crypts from the corrosive water. Engineers finished sinking the glass panels into the pavement to build the ring just in time for the November high tides. NASA scientists say that the Adriatic’s level is rising about 0.09 inches a year. Venice suffered only two high water events during the first half of the 20th Century, but recently, the city has been assaulted by 40 per decade. The city is also sinking. One study states that Venice sinks by 0.04 to 0.08 inches per year due to plate tectonics.

How China Avoids Paying for Climate Damage

In 1992, the United Nations classified China as a developing country, as hundreds of millions of its citizens lived in poverty.

A lot has changed since then: China is now the world’s second-largest economy and the biggest annual emitter of planet-warming greenhouse gases. Average Chinese today are 34 times richer and nearly four times more polluting. But the classification has stayed the same for the past three decades, frustrating diplomats from developed nations who say it has allowed Beijing to avoid paying its fair share to help poor countries cope with the ravages of climate change.
