Thailand – The downtown of Nakhon Si Thammarat was under water on Wednesday after the southern province was hit by overnight heavy rains. Several areas in the heart of Muang district were flooded as thevolume of rain overwhelmed the drainage system.

Philippines – A 22-year old man was reported missing as thousands of individuals in Eastern Visayas were affected by Tropical Depression ‘Samuel’ on Tuesday.

Texas, USA – Once every 100 years. That’s the mark of a major flood. That means homes have a one percent chance of experiencing a flood in any given year. Texas has had three 100-year flood events in five years. Scientists say it’s a sign of the times.

Disease

Ebola – DR Congo – Update

The Democratic Republic of the Congo (DRC) Ministry of Health (MOH) recorded 13 more new cases of Ebola bringing the cumulative number of cases is 386. Of this total, 339 are confirmed and 47 are probable. In total, there were 219 deaths (172 confirmed and 47 probable).

Measles – Colombia

A measles outbreak in Colombia has prompted the Centers for Disease Control and Prevention (CDC) to issue a travel notice last week. Between March and October this year, Colombia has reported 129 confirmed measles cases. Of the 129 confirmed cases, 45 were imported, 75 were import-related (25 cases of secondary transmission among persons coming from Venezuela).

Global Malaria Cases Plateau

Reductions in malaria cases have stalled after several years of decline globally, according to a new World malaria report. For the second consecutive year, the annual report produced by WHO reveals a plateauing in numbers of people affected by malaria: in 2017, there were an estimated 219 million cases of malaria, compared to 217 million the year before. But in the years prior, the number of people contracting malaria globally had been steadily falling, from 239 million in 2010 to 214 million in 2015.

In 2017, approximately 70% of all malaria cases (151 million) and deaths (274 000) were concentrated in 11 countries: 10 in Africa (Burkina Faso, Cameroon, Democratic Republic of the Congo, Ghana, Mali, Mozambique, Niger, Nigeria, Uganda and United Republic of Tanzania) and India. There were 3.5 million more malaria cases reported in these 10 African countries in 2017 compared to the previous year, while India, however, showed progress in reducing its disease burden.

Volcanos

Roundup of Global Volcanic Activity – New Activity for the week of 14 November – 20 November 2018

Fuego | Guatemala : INSIVUMEH and CONRED reported that activity at Fuego increased on 18 November, heralding the fifth effusive phase of 2018. Incandescent material was ejected 200-300 m above the crater rim and a lava flow in the Ceniza (SSW) drainage reached 2.5 km in length. Avalanches of material from the lava flow reached vegetated areas. Explosions occurring at a rate of 8-17 per hour generated ash plumes that rose at least 1.2 km and drifted 20-25 km W and SW. Ashfall was reported in areas downwind including Morelia (9 km SW), Santa Sofia (12 km SW), Sangre de Cristo (8 km WSW), Panimaché I and II (8 km SW), and Finca Palo Verde. Volcanic material also accumulated in the Taniluyá (SW) and Seca (W) drainages causing increased risk of avalanches. Later that day explosions became stronger, and incandescent material was ejected 400 m high. Ashfall continued to be reported in local communities. CONRED reported that a portion of National Route 14 was closed, and evacuations began in some local areas. Strombolian activity continued to intensify on 19 November with stronger explosions and increased seismicity. Incandescent material was ejected as high as 1 km above the crater. Ash plumes rose as high as 3.2 km and drifted 20-60 km W, SW, and NE. Pyroclastic flows descended the Seca drainage, and, along with ash emissions from the crater, caused ashfall in multiple areas including Santa Sofia, Sangre de Cristo, Panimaché I and II, and Finca Palo Verde. The lava flow in the Ceniza drainage advanced to 3 km long and produced avalanches from the flow front. Avalanches of tephra also descended the Seca, Ceniza, Taniluyá, Las Lajas, and Honda (E) drainages, reaching vegetated areas. CONRED noted that 3,925 people had been evacuated. INSIVUMEH noted that the effusive phase was over at 1800 on 19 November, having lasted for 32 hours. Explosions continued during 19-20 November, generating ash plumes which rose 0.8-1 km and drifted 10-15 km NW, W, and SW. Ash fell in areas downwind including El Porvenir (8 km ENE), Morelia, Santa Sofia, Sangre de Cristo, Panimaché I and II, and Finca Palo Verde. Incandescent material was ejected 100-300 m high, casing avalanches, some that traveled long distances. Some explosions generated shock waves that rattled nearby structures.

Mayon | Luzon (Philippines) : PHIVOLCS reported that during 14-20 November white steam plumes emitted from Mayon drifted downslope and then in multiple directions. Crater incandescence was visible at night. The Alert Level remained at 2 (on a 0-5 scale) and PHIVOLCS reminded residents to stay away from the 6-km-radius Permanent Danger Zone and the 7-km Extended Danger Zone on the SSW and ENE flanks.

Suwanosejima | Ryukyu Islands (Japan) : JMA reported that four explosions at Suwanosejima’s Ontake Crater were recorded during 9-16 November. The highest ash plume rose 2 km, the first time a plume from Ontake Crater rose that high since 4 April. Material was ejected 700 m from the crater. Ashfall was reported in an area 4 km SSW on 15 November. The Alert Level remained at 2 (on a 5-level scale).
