East Coast, USA – The category four hurricane was 500 miles southeast of Wilmington, North Carolina this morning, and is set to unleash torrential rain and high winds from Thursday to Saturday. Meteorologists are particularly concerned about the slow-moving nature of the hurricane, as this means areas will receive a concentrated burst of rain and wind. Parts of the Carolinas and the mid-Atlantic are likely to get 15 and 25 inches of rain by the end of the weekend. The National Hurricane Centre (NHC) said wave heights of up to 83 feet were measured this morning to the northeast of the hurricane.

The Zimbabwean Ministry of Health and Child care has declared the ongoing cholera outbreak in the capital Harare a state of national emergency as the death toll rose to 20. Over 2,300 suspected cases have been reported in Harare since the outbreak was confirmed on September 1.

Middle East respiratory syndrome coronavirus (MERS-CoV) infection – Republic of Korea

Volcanos

Roundup of Global Volcanic Activity – New Activity for the week of 5 September -11 September 2018

Etna | Sicily (Italy) : INGV reported that during 3-9 September activity at Etna was characterized by gas emissions at the summit craters, with periodic Strombolian activity from vents in Bocca Nuova, Northeast Crater (NEC), and New Southeast Crater (NSEC). A few Strombolian explosions at NSEC were recorded on 5 September; an explosion at 0536 generated an ash plume that produced local ashfall around the vent and in the Valle del Bove, and quickly dispersed. A similar but less intense event occurred earlier that day, at 0316. Similar Strombolian events continued during 6-9 September, at intervals of a few hours. Strombolian activity at the N vent (BN-1) in Bocca Nuova occurred at 3-5-minute intervals, ejecting incandescent material that fell within the crater confines. Gas emissions were sometimes punctuated with ash emissions. Intense degassing was characteristic of the second vent (BN-2). Strombolian activity occurred at NEC, and a few times explosions were accompanied by ash emissions.

Krakatau | Indonesia : Based on satellite data, the Darwin VAAC reported that on 8 September ash plumes from Anak Krakatau rose to altitudes of 4.9-5.5 km (16,000-18,000 ft) a.s.l. and drifted W and NW. During 9-10 September ash plumes rose to 1.5 km (5,000 ft) a.s.l. and drifted W. The Alert Level remained at 2 (on a scale of 1-4); residents and visitors were warned not to approach the volcano within 2 km of the crater.

Veniaminof | United States : On 4 September low-level ash emissions (less than 3 km or 10,000 ft a.s.l.) from Veniaminof were evident in webcam images and confirmed by observers in Perryville (35 km S), prompting AVO to raise the Aviation colour Code to Orange and the Volcano Alert Level to Watch. Seismicity was elevated. During 4-6 September pulsating, low-altitude ash plumes were visible from a Perryville webcam and reported by a pilot, and a small thermal anomaly was visible in satellite data. On 7 September the thermal signal increased, suggesting lava fountaining at the summit. Webcam images the next day showed minor ash or steam near the summit cone. Ash deposits on the snowfield formed a “V” shape from the summit, extending to the SSW and SE. On 9 September a lava flow, about 800 m long, was identified on the S flank in satellite data. Witnesses aboard a ferry passing Veniaminof early the next morning noted lava fountaining and an active lava flow. Lava flows continued on 11 September, though were confined to the summit caldera.
