Southern States, USA – A Tennessee hillside collapsed, roads were flooded and rivers were rising across the Southeast on Tuesday after a day of heavy rains that once again threatened a Mississippi lake where a dam previously was in danger of failing. The National Weather Service said minor to moderate flooding was expected from central Mississippi to north Georgia following downpours. The Tennessee River was predicted to crest about 7 feet above flood level at Perryville, Tennessee, on Sunday. Near Great Smoky Mountains National Park in eastern Tennessee, tons of rock and soil slid off a 70-foot high hillside. Multiple roads were covered with water or washed out because of rainfall that exceeded 5 inches in spots across central Alabama.

Wildfires

Wildfires – Corsica

Strong winds from Storm Ciara have fanned a wildfire on the island of Corsica. Several hundred firefighters are battling the blaze which has consumed more than 450 hectares to date.

Disease

Novel Coronavirus

USA – The Centers for Disease Control and Prevention (CDC) reported Wednesday evening on an additional infection with 2019 novel coronavirus (COVID-19) in the United States in California, bring the case total to 14.

China – Some 242 deaths from the new coronavirus were recorded in the Chinese province of Hubei on Wednesday – the deadliest day of the outbreak. There was also a huge increase in the number of cases, with 14,840 people diagnosed with Covid-19. Hubei has started using a broader definition to diagnose people – which accounts for most of the rise in cases. The new cases and deaths in the province have pushed the national death toll above 1,350 – with almost 60,000 infections in total.

Polio – Africa Travel Notice

The Centers for Disease Control and Prevention (CDC) renewed their polio travel notice for Africa Tuesday. There are polio outbreaks in several countries in Africa. The following 15 countries have been reporting outbreaks: Angola, Benin, Burkina Faso, Cameroon, Central African Republic, Chad, Democratic Republic of the Congo, Ethiopia, Ghana, Mozambique, Niger, Nigeria, Somalia, Togo and Zambia.

Volcanos

Roundup of Global Volcanic Activity – New Activity for the Week 5 February 2020 – 11 February 2020

Kuchinoerabujima | Ryukyu Islands (Japan) : JMA reported that after the 3 February eruption at Kuchinoerabujima’s Shindake Crater the number of volcanic earthquakes decreased, and very small eruptive events occurred intermittently though 5 February and on 9 February. A large amount of ashfall (including lapilli up to 2 cm in diameter) was confirmed on the SE flank during field observations on 3 and 6 February. Thermal image observations revealed 5-km-long pyroclastic flow deposits on the SW flank. The number of volcanic earthquakes began increasing on 9 February and continued to be elevated the next day. A large-amplitude volcanic tremor event was accompanied by fluctuating tilt at 1318 on 11 February. The Alert Level remained at 3 (the middle level on a scale of 1-5).

Piton de la Fournaise | Reunion Island (France) : OVPF reported that a seismic crisis at Piton de la Fournaise began at 1027 on 10 February, accompanied by rapid deformation. Volcanic tremor began just 23 minutes later, at 1050, heralding the start of a new eruption. During an overflight conducted during 1300-1330 in partly cloudy weather, observers noted that several fissures had opened on the E flank of Dolomieu Crater, between the crater rim and 2,000 m elevation. The fissures all were at least 1 km long and produced lava fountains that were no higher than 10 m. Lava flows had traveled E to 1,700 m elevation by 1315. In the evening mapping of the lava flows based on satellite data revealed a larger flow field that what was visually observed during the overflight hours before. Lava flows spanned from the E to the S, with the farthest flow traveling E to 1,400 m elevation. The data showed that the fissures at the highest elevation had opened in the same area as those from the 18 February and 11 June 2019 eruptions.

Reykjanes | Iceland : On 7 February IMO reported that data collected during the previous week indicated that a magma body was located 3-5 km beneath Reykjanes. Earthquake activity had decreased during the previous two days, though inflation was ongoing, reaching 5 cm. The Aviation Code remained at Yellow.

Semeru | Eastern Java (Indonesia) : The Darwin VAAC reported that on 5 February an ash plume from Semeru rose to an altitude of 4.3 km (14,000 ft) a.s.l., or 400 m above the crater rim, and drifted SE based on satellite images and weather models. PVMBG noted that on 7 February a gray ash plume rose 400 m and drifted S. The Alert Level remained at 2 (on a scale of 1-4).

Taal | Luzon (Philippines) : PHIVOLCS reported that whitish steam plumes rose as high as 300 m above Taal’s main vent during 5-11 February and drifted SW. Sulfur dioxide emissions ranged from values below detectable limits to a high of 116 tonnes per day (on 8 February). Weak steaming (plumes 10-20 m high) from ground cracks was visible along the Daang Kastila trail which connects the N part of Volcano Island to the N part of the main crater. According to the Disaster Response Operations Monitoring and Information Center (DROMIC) there were a total of 17,088 people in 110 evacuation centers, and an additional 211,729 people were staying at other locations as of 10 February. The Alert Level remained at 3 (on a scale of 0-5) and PHIVOLCS recommended no entry onto Volcano Island and Taal Lake, nor into towns W of the island within a 7-km radius.
