Sri Lanka – Heavy rain since the start of August has caused flooding and landslides in Sri Lanka. As of 03 August at least 3 people had lost their lives and 2,374 were displaced. Sri Lanka’s Department of Meteorology reported 243.2 mm of rain fell in Norton in Nuwara Eliya District in 24 hours to 02 August 2022. The following day 212 mm of rain was recorded at the weather station near the Canyon Reservoir Dam, also in Nuwara Eliya District.

The Gambia – At least 2 people have died and over 230 households have been severely affected or displaced after the heaviest rainfall in over 20 years caused flooding in parts of the Gambia from late July 2022. Affected areas include the capital Banjul and Kanifing Local Government Area, as well as the West Coast and North Bank Regions. Two people died and 1 was severely injured in storms and floods in North Bank on 30 July 2022. At least 235 households have been affected after flooding damaged homes. Some of the residents have moved to safer areas, taking refuge in public buildings. Flood survivors are in urgent need of water, sanitation and hygiene (WASH) services.

Global Warming

The term “global warming” appeared for the first time in 1975

The term “global warming” appeared for the first time in print on August 8, 1975, with the publication of Wallace Smith Broecker’s paper “Climatic Change: Are We on the Brink of a Pronounced Global Warming?” in the journal Science.

Broecker argued that there was an increasingly likely scenario for this to happen: the ongoing rise of atmospheric carbon dioxide content created by fossil fuel emissions would soon begin to warm the planet, in turn warming surface waters in the ocean and melting ice into fresh water. This would reduce the waters’ density, thereby preventing cold water from sinking, altering ocean currents and effectively shutting off the conveyor belt. If that were to happen, he postulated, Europe would grow cooler as it did during the Ice Age. The more disruptive effect would come from unpredictable “on-and-off flickers” in global temperature. As Broecker put it in 1998, “the climate system is an angry beast and we are poking it with sticks.”


Wildfires – California, USA

A week ago, the scenic Northern California hamlet of Klamath River was home to about 200 people and had a community center, post office and a corner grocery store. Now, after the McKinney wildfire raged through the forested region near the Oregon state line, four people are dead and the store is among the few buildings not reduced to ashes.

More than 100 buildings ranging from homes to sheds have burned. Identifying the four people who were killed could take several days. The fire has charred nearly 90 square miles (233 square kilometers) and is the largest in California so far this year. The cause is unknown.

Monkeypox, Typhoid, Plague – DR Congo

From 1 January – 28 July 2022, the Democratic Republic of the Congo reported 2,266 suspected including 163 confirmed cases from 116 health zones across 20 provinces.

In 2022, from the beginning of the year to 10 July 2022, 1,021,535 suspected cases of typhoid fever including 471 deaths were recorded in the Democratic Republic of the Congo.

DRC reports 537 suspected plague cases in the health zone of Rethy, located in Djugu territory, Ituri province, DR Congo for the four month period of 27 Mar 2022 to 31 Jul 2022.

Crimean-Congo hemorrhagic Fever – Iraq

In a brief statement, the ministry stated that the number of hemorrhagic fever cases rose to 273, while 49 deaths were recorded.


Roundup of Global Volcanic Activity – New Activity for the week 27 July – 2 August 2022

Aira – Kyushu (Japan) : JMA lowered the Alert Level for Aira Caldera’s Sakurajima volcano to 3 (on a 5-level scale) on 27 July, noting that after the larger eruption on 24 July material had not been ejected more than 2 km from the crater; residents were warned to stay 2 km away from the crater. During 25 July-1 August the seismic network recorded about 11 explosions and 19 eruptive events, producing plumes that rose as high as 2.2 km above the summit and ejected material far as 1.1 km. Crater incandescence was visible nightly. No deformation was detected.

Askja – Iceland : On 27 July IMO stated that uplift at Askja began in August 2021 and since then had totaled 35 cm, centered in the W part of Askja lake. The uplift was rapid, compared to similar volcanoes around the world, and likely caused by a magmatic intrusion at an estimated depth of 2 km. Seismicity remained low.

Ioto – Volcano Islands : Satellite images of Ioto (Iwo-jima) acquired on 15 July showed a darker area in the water along the SE coast, possibly above or near the 2001 vent, and a plume of discolored water drifting NE. Video taken on or around 25 July showed a white plume rising from the same area. Satellite images during 30-31 July showed small rounded gray zones at the water surface.

Krysuvik-Trolladyngja – Reykjanes Peninsula : Icelandic Meteorological Office (IMO) reported that an intense earthquake swarm began around noon on 30 July within the Krýsuvík-Trölladyngja volcanic system. The earthquakes were located in an area just NE of lava field in Geldingadalir, along the dike intrusion that preceded the March-September 2021 eruption. The swarm was likely caused by a magmatic intrusion at depths of 5-7 km. Earthquakes were reportedly felt in SW Iceland, in Reykjanesbær, Grindavík, the Capital region, and as far as Borgarnes. Several earthquakes were above M 3; a larger M 4 event was recorded at 1403. IMO raised the Aviation Color Code to Yellow, based on above-background seismic levels. At around 1800 the epicenters shallowed to depths of 2-5 km. By 1527 on 31 July almost 3,000 earthquakes had been detected, with four of the events larger than an M 4. A larger M 5.4 earthquake was detected at 1748. IMO reported at 1749 on 2 August that deformation models indicated magma around 1 km below the surface. The intrusion rate was close to double that recorded prior to the 2021 eruption, though by the reporting time the intrusion and seismicity rates had slowed. IMO noted that a similar pattern of events took place prior to the last eruption and stated that the likelihood of an eruption had increased. An effusive eruption began at 1315 on 3 August in Meradalir, near the border of the previous flow field N of Fagradalsfjall. Webcam video showed lava fountains rising along a 300-m-long fissure.

Kuchinoerabujima – Ryukyu Islands (Japan) : JMA reported that the number of volcanic earthquakes with hypocenters near Kuchinoerabujima’s crater began increasing around 1000 on 30 July and remained elevated. The Alert level was raised to 2 (on a scale of 1-5) on 31 July. Around 40 volcanic earthquakes were recorded by 1500 on 1 August. JMA noted that daily emissions of sulfur dioxide gas remained low, with a rate less than 50 tons per day. No deformation was detected.

Raung – Eastern Java : According to PVMBG an eruption at Raung at 1719 on 27 July produced a gray ash plume that rose 1-1.5 km above the summit and drifted W and NW. On 28 July a thermal anomaly in the crater was identified in satellite images and data from the GPS network indicated inflation, likely from an intrusion of magma. Seismicity on 29 July was dominated by continuous tremor. The Alert Level was raised to 2 (on a scale of 1-4) that same day, and the public was warned to stay 3 km away from the crater.
