Somalia – After a poor rainy season early this year, parts of southern Somalia now are being hit with severe floods. The rainy season that began in October has caused flooding along the Shebelle and Juba Rivers. The U.N. Food and Agriculture Organization warns that’s making ongoing food insecurity even worse. The U.N. estimates more than one-million people in Somalia are in urgent need of assistance – a 20-percent increase in the past six months. What’s more, it says another two-million people are facing threats to their food security. Much of Somalia’s farming takes place along the Shabelle and Juba Rivers. Along the Shabelle, the town of Belet Weyne is the worst hit. Along the Juba, flooding is reported in Dollow, Jilib and Jamame.

Space Events

Solar Salvo Sends Blasts Into Space

The largest group of sunspots seen in nearly a quarter-century sent a barrage of solar flares into space, three of which were among some of the most powerful that the sun can create.

Solar flares are gigantic explosions on the surface of the sun, which send streams of dangerous charged particles rushing into space.

If Earth happens to be in the path of the blasts, the resulting geomagnetic storms can knock out satellite electronics, disrupt high-frequency communications and even bring down power grids.

Such storms also produce vivid aurora displays.

The only significant effects on Earth from the latest blasts by the AR 12192 sunspot were radio blackouts at some frequencies. This is mainly because the solar eruptions did not send out blasts of plasma, known as coronal mass ejections.

The largest sunspot in history was observed in 1947 and grew to be three times larger than the one currently producing the swarm of flares.

Many skywatchers who were taking photos of the partial solar eclipse across North America during the previous week managed to capture images of the massive sunspot as well.

Middle East respiratory syndrome coronavirus (MERS-CoV) – Qatar

Roundup of Global Volcanic Activity

Shishaldin (United States, Aleutian Islands): Eruptive activity at the volcano continues. Most of the time, it seems to be weak, probably strombolian in nature, but there have been episodes with more intense activity, possibly lava fountaining, evidenced by strong tremor and elevated surface temperatures. Such an episode occurred during 25-28 Oct. Elevated surface temperatures were observed in satellite images beginning on October 25, and early that evening seismic tremor began to be recorded on nearby seismic stations, accompanied by stronger thermal anomalies. New deposits of ash and ballistics darkened the summit area, indicating the activity was energetic enough to eject material from a depth of several hundred meters (~600 ft / 200 m) within the summit crater. The activity was recorded on infrasound arrays located in Akutan, 90 mi (145 km) to the southwest, and Dillingham, 363 mi (585 km) to the northeast. (AVO)
