New Your, USA – The New York City metropolitan area was flooding Wednesday night as the remnants of Hurricane Ida flooded subways, roads, and homes. At least 38 were killed in New York and New Jersey, and at least 43 in the Northeast total. Ida’s remnants didn’t just batter the tristate area, though. It raked its way up the Eastern Seaboard, leaving devastating rainfall in its wake, and spawning tornadoes along the way. At least four were dead in Pennsylvania, where the storm deluged Philadelphia, bringing major flooding to the Schuylkill River.


Nuclear Contamination

Contaminated water now stored in about 1,000 tanks at Japan’s crippled Fukushima nuclear power plant will be released offshore into the Pacific through a newly planned undersea tunnel.

Operators say they will drill through bedrock beneath the seabed and begin releasing the water about 40 feet below the ocean’s surface beginning in the spring of 2023. They say the scheme is designed to avoid interfering with local fishing.

The stored water from the plant’s meltdowns will first be diluted with large amounts of seawater to reduce the concentration of the radioactive material.

Northernmost Land

Members of a Danish research expedition to Greenland’s northern coastal waters say they accidently discovered what is now believed to be the northernmost island on the planet. While unsuccessfully trying to locate and land on Oodaaq Island to collect samples, they instead “landed on a strange unvegetated bunch of mud, moraine deposits and gravel surrounded by sea ice on all sides.”

After checking their position, the found they were not on Oodaaq, but on land about 3,600 feet farther north than what was previously thought to be the island nearest to the North Pole. The team wants the newly discovered island to be named Qeqertaq Avannarleq, which means “the northernmost island” in Greenlandic.


Global Warming

Disasters Soar

Natural disasters such as deadly heat waves and floods are now occurring five times more often than they did 40 years ago, which the U.N. weather agency says is directly linked to human-driven global heating.

The World Meteorological Organization’s new “Atlas” reviews the human tragedies and economic losses from weather extremes and water, and is said to be the most detailed ever produced. It shows that such disasters have killed more than 2 million people since 1970 and have cost $3.64 trillion in losses.


Unnatural LED Lights

The switch to more energy-efficient light-emitting diodes (LEDs) in many of the world’s streetlamps has not only disrupted insect behavior, but researchers say it is also leading to a decline in at least some insect populations.

Researchers from the U.K. Center for Ecology & Hydrology say they found 50% fewer moth caterpillars living immediately around the LED lights along rural roads in southern England, compared to their numbers near traditional illumination. The scientists say the trend is alarming since small birds, hedgehogs and predatory insects feed on the caterpillars, while larger birds and bats eat the adult moths.


Global Temperature Extremes

The week’s hottest temperature was 124 degrees Fahrenheit (51.1 degrees Celsius) Bordj Badji Mokhtar,Algeria.

The week’s coldest temperature was minus 98.0 degrees Fahrenheit (minus 72.2 degrees Celsius) at the South Pole, 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.

Ebeko – Paramushir Island (Russia) : According to volcanologists in Severo-Kurilsk (Paramushir Island), about 7 km E of Ebeko, explosions during 20-21 and 24-25 August produced ash plumes that rose as high as 4.6 km (15,100 ft) a.s.l. and drifted SE. A thermal anomaly was identified in satellite images during 20 and 23-25 August.

Etna – Sicily (Italy) : INGV reported that activity at Etna was concentrated at the Southeast Crater (SEC) during 23-29 August. Gas emissions rose from Bocca Nuova crater. A series of explosions at SEC that began at 1530 on 27 August and continued through the next morning produced ash puffs. Strombolian activity began in the early afternoon of 29 August and within an hour, lava fountains were visible rising up to 400 m above the vent. Ash emissions rose a few hundred meters. The activity varied in intensity and during intense periods, ash plumes rose up to 10 km above the summit. Ash and lapilli fell in areas to the E, including in Fornazzo, Milo, San Alfio, and Giarre. Lava flows from the SEC traveled SW and one from the E base traveled E toward the Valle del Bove.

Great Sitkin – Andreanof Islands (USA) : AVO reported that the lava dome at Great Sitkin continued to grow, reaching 880 m in diameter by 25 August and 1,090 m during 28-29 August. Elevated surface temperatures and small earthquakes were detected during 25-31 August, consistent with the growing dome.

Kadovar – Papua New Guinea : Based on satellite and wind model data, the Darwin VAAC reported that on 27 and 30 August ash plumes from Kadovar rose to altitudes of 1.2-1.5 km (4,000-5,000 ft) a.s.l. and drifted W and WNW.

Katmai – United States : AVO reported that on 28 August strong winds in the vicinity of Katmai and the Valley of Ten Thousand Smokes picked up unconsolidated ash and drifted SE towards Kodiak Island at an altitude up to 1.8 km (6,000 ft) a.s.l. The ash was originally deposited during the Novarupta eruption in 1912.

Lewotolok – Lembata Island (Indonesia) : PVMBG reported that the eruption at Lewotolok continued during 25-30 August. White, gray, and sometimes black plumes rose as high as 1.2 km above the summit and drifted W and NW.

Merapi – Central Java (Indonesia) : BPPTKG reported that of Merapi’s two lava domes, the dome just below the SW rim was more active than the dome in the summit crater during 20-26 August. The SW dome grew and shed material down the flanks, increasing in height by just 3 m overall. On 25 August the volume of the SW dome was estimated at 1.4 million cubic meters and the summit lava dome was stable at an estimated 2.831 million cubic meters. A total of two pyroclastic flows descended the SW flank as far as 2 km; as many as 211 lava avalanches traveled a maximum of 2 km SW. Based on satellite images the Darwin VAAC noted that during 28-29 August ash plumes rose to 3-3.7 km (10,000-12,000 ft) a.s.l. and drifted SW, W, and NW.

Deformation data indicated minor changes. Gas-and-steam emissions were sometimes visible in satellite data and webcam images rising as high as 1.2 km above the summit and drifting NW and W. These emissions sometimes contained ash; on 26 August an ash emission rose 490 m and drifted WNW.

Rincon de la Vieja – Costa Rica : OVSICORI-UNA reported that small eruptive events at Rincón de la Vieja were recorded at 1915, 2049, and 2053 on 26 August, though weather conditions prevented visual confirmation of emissions. A one-minute-long phreatic eruption was recorded at 1446 on 27 or 28 August and produced an eruption plume that rose 1 km above the crater rim.

Sabancaya – Peru : Instituto Geofísico del Perú (IGP) reported a daily average of 36 explosions at Sabancaya during 23-30 August. Gas-and-ash plumes rose as high as 3.5 km above the summit and drifted S, SW, N, and NE. Ten thermal anomalies originating from the lava dome in the summit crater were identified in satellite data. Minor inflation continued to be detected near Hualca Hualca (4 km N).

Sheveluch – Central Kamchatka (Russia) : KVERT reported that the lava dome at Sheveluch continued to grow and produced hot lava avalanches during 20-27 August. A daily bright thermal anomaly was identified in satellite images and gas-and-steam plumes containing some ash drifted 307 km NE, E, and SE. At 1100 on 29 August an ash plume 14×15 km in dimension drifted 30 km W at altitudes of 2.5-3 km (8,200-10,000 ft) a.s.l. On 28 August the Kamchatka Branch of Geophysical Services (KBGS; Russian Academy of Sciences) posted photos of the incandescent dome and avalanches, noting that small landslides and hot avalanches periodically traveled down the S and SE flanks of the dome. Larger landslides were observed 2-4 times per night.

Sinabung – Indonesia : PVMBG reported that on most days during 25-31 August white gas-and-steam plumes from Sinabung rose as high as 500 m above the summit and drifted in multiple directions. Lava avalanches traveled 700 m down the flanks on 25 August.

Stromboli – Aeolian Islands (Italy) : INGV reported that during 23-29 August activity at Stromboli was characterized by ongoing explosive activity from three vents in Area N (North Crater area) and six vents in Area C-S (South-Central Crater area). Explosions from the N1 vent (Area N) ejected lapilli and bombs 80 m high, and produced minor ash emissions. Explosions at N2 vents (Area N) averaged 4-5 events per hour and ejected material 80 m high. Explosions from the S1 and S2 vents in Area C-S were sporadic and occurred at a rate of 5-12 per hour; coarse material was ejected 120 m high. Gas emissions rose from the C vent.
