Puerto Rico – Hurricane Maria is likely to have “destroyed” Puerto Rico, the island’s emergency director said Wednesday after the monster storm ripped roofs off buildings and flooded homes. Intense flooding was reported across the economically strained U.S. territory, particularly in San Juan, the capital, where many residential streets looked like rivers. The National Weather Service issued a flash flood warning for the entire island shortly after 12:30 a.m. ET. Maria battered the northwestern coast of Puerto Rico with sustained winds of up to 115 mph (185 km/h), knocking out power on the entire island.

Thailand – Heavy rain briefly pounded several districts in Bangkok on Wednesday. Phra Khanong was hardest hit by the downpour with 61.5 millimetres of rain. Some roads in 12 districts were flooded before the water drained later in the day. The flood situation remained serious in Kalasin, Phitsanulok and Satun due to the impact of storm Doksuri, which flooded 12 provinces from Friday to Tuesday.

Disease

Hepatitis A in Sydney, Australia

There are reports of a serious hepatitis A outbreak across Victoria and Sydney. Affecting sexually active gay men, the disease is believed to be spread by European travelers and has been reported in four Sydney-based men already.

Since 2016, hepatitis A outbreaks among MSM (male to male sexual contact) have been reported in 16 European countries and numerous states in the USA. In total, there have been around 1,500 confirmed cases in Europe. The strain detected in Sydney is similar to that circulating in Europe, further solidifying beliefs that the disease has been spread from these travelers.

Volcanos

Roundup of Global Volcanic Activity – New Activity for the week of 13 September-19 September 2017

Agung | Bali (Indonesia) : Increased seismicity at Agung, as well as the severity of past eruptions, prompted PVMBG to raise the Alert Level to 2 (on a scale of 1-4). The report noted that volcanic earthquakes (VA) began to be recorded on 10 August and shallow volcanic earthquakes (VB) began to be recorded on 24 August. Local tectonic earthquakes were also recorded and began to increase consistently on 26 August. PVMBG warned the public to stay at least 3 km away from the crater. On 13 September a climber observed a sulfatara plume rising from the bottom of the crater as high as 50 m above the crater rim. During 14-18 September four earthquakes centered around Agung were felt. On 18 September PVMBG reported that the number of VA and VB events continued to increase; the Alert Level was increased to 3. The exclusion zone was increased to 6 km, with an additional expansion to 7.5 km in the N, SE, and SSW directions. Elevations above 950 m were also restricted.

Dieng Volcanic Complex | Central Java (Indonesia) : PVMBG reported that during 8 July-14 September measurements indicated an increase in water temperature at Sileri Crater lake (Dieng Volcanic Complex) from 90.7 to 93.5 degrees Celsius. Soil temperatures also increased, from 58.6 to 69.4 degrees Celsius. At Timbang Crater temperatures in the lake increased from 57.3 to 62.7, and in the soil they decreased from 18.6 to 17.2. The report noted that conditions at Timbang Crater were normal. Temperature increases at Sileri, along with tremor detected during 13-14 September, prompted PVMBG to raise the Alert Level to 2 (on a scale of 1-4). PVMBG warned the public to stay at least 1 km away from the crater rim, and for residents living within that radius to evacuate.

Zhupanovsky | Eastern Kamchatka (Russia) : Based on visual observations, KVERT reported that on 17 September explosions at Zhupanovsky generated gas-and-steam plumes with small amounts of ash that rose to altitudes of 6-7 km (19,700-23,000 ft) a.s.l. and drifted 20 km SW. The Aviation colour Code was raised from Green to Orange, the second highest level on a 4-colour scale. About 30 minutes later satellite images showed ash plumes drifting 10 km E. Later that day gas-and-steam plumes rose 4 km (13,100 ft) a.s.l. The Aviation colour Code was lowered to Yellow, and then on 20 September it was lowered to Green.
