Namibia – The Hydrological Services of Namibia has warned communities in the northern and north-eastern parts of the country to be on high alert for possible flooding as water levels in the Zambezi, Kavango and Kunene rivers continue to rise.

Yemen – Heavy rains have been causing floodwaters to sweep through some areas of war-torn Yemen, overturning cars and damaging shops especially in the capital Sanaa and in Ma’rib.

Wildlife

World’s Longest Animal

Despite advances in technology and research methods, much of the natural world is still waiting to be discovered.

Now scientists from the Schmidt Ocean Institute, exploring the ocean off Western Australia’s coast, have made some astounding discoveries – including what they believe to be 30 new species, along with what may be “the longest animal ever seen”.

One of the biggest discoveries was a siphonophore measuring an estimated 150 feet (46 metres). Siphonophores are deep-sea predators made up of many small clones that act together as one and spread out like a single long string in the water. Researchers think this particular siphonophore may be the longest yet found. Siphonophores feed in much the same way as jellyfish. They dangle stinging tentacles in the water. If an unlucky fish makes contact with the tentacles they are stung, paralysed, and then pulled up into the body of the siphonophore.

Roundup of Global Volcanic Activity – New Activity for the Week 8 April 2020 – 14 April 2020

Kerinci | Indonesia : According to the Darwin VAAC, PVMBG reported that on 10 April an ash plume from Kerinci rose 600 m above the summit and drifted NW. On 13 April an observer noted that an ash plume rose to 900 m above the summit; the emission was not visible in satellite data. An ash plume rose 400 m above the summit on 14 April; meteorological clouds obscured views. The Alert Level remained at 2 (on a scale of 1-4), and the public was warned to remain outside of the 3-km exclusion zone.

Krakatau | Indonesia : PVMBG reported that at 2158 and 2235 on 10 April an eruptive event at Anak Krakatau generated dense white, gray, and black ash plumes that rose as high as 2 km above the summit and drifted S and E. The events were followed by Strombolian activity that ejected incandescent material onto the crater floor and summit areas; video revealed lightning visible in the ash cloud. The Darwin VAAC issued a notice at 0145 on 11 April stating that an eruption plume had risen to 14.3 km (47,000 ft) a.s.l., but noted low confidence in the altitude due to the possible mixing of the eruption plume with meteorological storm clouds. An intense thermal anomaly was visible. An hour later the VAAC reported an on-going sulfur-rich plume rising to 11.3 km (37,000 ft) a.s.l. and drifting W; the previous plume remained visible and continued to drift NW. Later that day ash plumes rose to 3 km (10,000 ft) a.s.l. and drifted N. During 12-13 April plumes comprised mostly of sulfur dioxide and steam rose to 3 km (10,000 ft) a.s.l.; the plumes did not have a strong ash signal. The Alert Level remained at 2 (on a scale of 1-4), and the public was warned to remain outside of the 2-km-radius hazard zone from the crater.

Semeru | Eastern Java (Indonesia) : PVMBG reported that during 6-12 April dense white-gray plumes rose 200-500 m above Semeru’s summit. Incandescent material was ejected 20 m above the Jonggring-Seloko Crater. Incandescent material from the ends of lava flows descended 200-1,000 m, reaching a maximum distance of 750-1,500 m from the crater. 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.

Shishaldin | Fox Islands (USA) : AVO reported elevated seismicity at Shishaldin during 8-13 April characterized by occasional low-frequency earthquakes. Minor steaming from the summit crater was sometimes seen in satellite and webcam data. A small thermal anomaly was visible in satellite data during 8-9 April. The Volcano Alert Level remained at Watch and the Aviation colour Code remained at Orange.
