Somalia – Further flooding has struck in parts of Somalia, with over 10,000 people affected in South West State over the last few days. Wide areas of the country have seen unusually strong “Hagaa season” rainfall which has caused flash and riverine flooding in particular from mid July. Since then, 6 fatalities have been reported and at least 120,000 people displaced and 191,000 affected in Hirshabelle, South West, Jubaland States and Banadir region. Further flooding struck after rivers broke their banks in Marka district, South West State, on 01 August, 2020. According to the UN Office for the Coordination of Humanitarian Affairs (UN OCHA), flooding has damaged homes and crops. Around 6,000 people have been displaced and moved to nearby Internally displaced people (IDPs) sites.

Saudi Arabia – Saudi Arabia’s General Directorate of Civil Defense (CDD) reports that ongoing heavy rain across the country has prompted dozens of high water rescues. Rescues were carried out in Makkah, Al Madinah, ‘Asir, Jizan, and Al Bahah regions. In a period 26 July to 04 August, a total of 77 people have been rescued and around 600 evacuated their homes and moved to temporary shelter. Asir region was reportedly the worst affected. In addition, CDD reported that 3 people have died in separate flood incidents in Baish in Jizan, Adham in Makkah and Najran in Najran Region.


Penguin Disovery

There are now 20% more known colonies of emperor penguins around Antarctica, thanks to satellite images that revealed more of the imperiled birds to scientists. Emperors are the only penguin species that breed on sea ice instead of on land, making them highly vulnerable to climate change. “Whilst this is good news, the colonies are small and so only take the overall population count up to … just over half a million penguins,” said lead researcher Peter Fretwell at the British Antarctic Survey. He made the discovery by examining images from Europe’s Sentinel-2 spacecraft. Fretwell says there still may be one or two other very small colonies yet to be discovered.


Global Temperature Extremes

The week’s hottest temperature was 122 degrees Fahrenheit (50.0 degrees Celsius) in Al Ahsa, Saudi Arabia.

The week’s coldest temperature was minus 101.0 degrees Fahrenheit (minus 73.9 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.

Roundup of Global Volcanic Activity – Ongoing Activity for the Week 29 July 2020 – 4 August 2020

Dukono | Halmahera (Indonesia) : Based on information from PVMBG and satellite data, the Darwin VAAC reported that ash plumes from Dukono rose to 2.1 km (7,000 ft) a.s.l. and drifted in multiple directions during 29 July-3 August. The Alert Level remained at a 2 (on a scale of 1-4), and the public was warned to remain outside of the 2-km exclusion zone.

Ebeko | Paramushir Island (Russia) : KVERT reported that a thermal anomaly over Ebeko was identified in satellite images during 23-24 and 28 July. Volcanologists in Severo-Kurilsk (Paramushir Island), about 7 km E, observed explosions during 26-30 July that sent ash plumes up to 3.5 km (11,500 ft) a.s.l. and drifted S and E. The Aviation colour Code remained at Orange (the second highest level on a four-colour scale).

Fuego | Guatemala : INSIVUMEH reported that at 2050 on 29 July lahars descended the Las Lajas and El Jute drainages on Fuego’s SE flanks. There were 6-13 explosions per hour recorded during 29 July-4 August, generating ash plumes as high as 1.1 km above the crater rim that generally drifted 15-20 km NW, W, and SW. Shock waves rattled buildings within a 20-km radius, particularly in areas on the S flank. Incandescent material ejected 100-350 m high caused avalanches of blocks in the Ceniza (SSW), Seca (W), Trinidad (S), Taniluyá (SW), Las Lajas, and Honda drainages; avalanches sometimes reached vegetated areas. Ashfall was reported in several areas downwind including Morelia (9 km SW), Panimaché I and II (8 km SW), Finca Palo Verde, San Pedro Yepocapa (8 km NW), and Sangre de Cristo (8 km WSW).

Ibu | Halmahera (Indonesia) : PVMBG reported that during 29-30 July white-to-gray plumes rose 200-800 m above Ibu’s summit and drifted NW; weather conditions prevented visual observations during 31 July-1 August. The Darwin VAAC reported a thermal anomaly in satellite images on 31 July. The Alert Level remained at 2 (on a scale of 1-4), and the public was warned to stay at least 2 km away from the active crater, and 3.5 km away on the N side.

Kadovar | Papua New Guinea : Based on satellite and wind model data, the Darwin VAAC reported that on 30 July an ash plume from Kadovar rose to an altitude of 1.5 km (5,000 ft) a.s.l. and drifted NW. An ash plume rose to 1.2 km (4,000 ft) a.s.l. and drifted NW on 3 August.

Karymsky | Eastern Kamchatka (Russia) : KVERT reported that a thermal anomaly over Karymsky was identified in satellite images during 24-31 July. Strombolian and Vulcanian explosions during 27-30 July produced ash plumes that rose to 3-3.5 km (10,000-11,500 ft) a.s.l. and drifted 250 km SW and SE. The Aviation colour Code remained at Orange (the second highest level on a four-colour scale).

Nevado del Ruiz | Colombia : Servicio Geológico Colombiano’s (SGC) reported that a seismic signal associated with fluid movement beneath Nevado del Ruiz was recorded at 0636 on 30 July. Concurrently a small gas-and-ash plume visible with the webcam rose as high as 560 m above the summit. The Alert Level remained at 3, Yellow (the second lowest level on a four-colour scale).

Pacaya | Guatemala : INSIVUMEH reported that during 29 July-3 August Strombolian explosions at Pacaya’s Mackenney Crater ejected material as high as 150 m above the crater rim. No active lava flows were visible.

Santa Maria | Guatemala : INSIVUMEH reported that during 29 July-4 August explosions at Santa María’s Santiaguito lava-dome complex generated ash plumes that rose 900 m above the crater and drifted as far as 1 km W and SW. Avalanches of blocks descended the SE, S, and SW flanks of Caliente cone; some reached the base of the cone and were sometimes accompanied by small pyroclastic flows. Minor ashfall was noted in areas downwind including San Marcos (10 km SW), Loma Linda (6 km WSW), and Palajunoj (18 km SSW) during 29-30 July and 2-4 August.

Semeru | Eastern Java (Indonesia) : PVMBG reported that activity at Semeru continued during 29 July-4 August, though weather conditions often prevented visual confirmation. White-and-gray ash plumes rose 200-400 m above the summit and drifted S on 29 July. The Alert Level remained at 2 (on a scale of 1-4), and the public was reminded to stay outside of the general 1-km radius from the summit and 4 km on the SSE flank.

Sheveluch | Central Kamchatka (Russia) : KVERT reported that a thermal anomaly over Sheveluch was identified in satellite images during 24-31 July. The Aviation colour Code remained at Orange (the second highest level on a four-colour scale).

Suwanosejima | Ryukyu Islands (Japan) : JMA reported that nighttime incandescence at Suwanosejima’s Ontake Crater was occasionally visible during 24-31 July. Occasional eruptive events were recorded. An explosion at 1200 on 27 July generated a gray plume that rose as high as 2 km above the crater rim. The Tokyo VAAC reported that during 1-3 August ash plumes rose to 1.8-2.4 km (6,000-8,000 ft) a.s.l. and drifted NW and W. The Alert Level remained at 2 (on a 5-level scale).
