Middle East respiratory syndrome coronavirus (MERS-CoV) – Saudi Arabia

From 1 June through 16 September 2018, the International Health Regulations (IHR 2005) National Focal Point of Saudi Arabia reported 32 additional cases of Middle East Respiratory Syndrome (MERS), including 10 deaths.

Dengue Fever – Mexico

Health authorities of the state of Chiapas, on the southernmost tip of Mexico, are reporting a large number of dengue fever cases, prompting a health alert in the area. The state Department of Public Health has revealed that 2,600 cases have been treated this year, 1,350 confirmed and 8 deaths have been recorded.

Measles – Brazil – Update

The Brazil Ministry of Health reported that as of October 1, there are 1,935 measles cases confirmed throughout the country. In Amazonas, there are 1,525, and in Roraima, 330. The outbreaks are all related to importation, as the genotype of the virus (D8) that is circulating in the country is the same that circulates in Venezuela, a country that has been facing an outbreak of the disease since 2017.

More Cholera Cases – Nigeria

The Yobe State Ministry of Health reported Oct 1 that 36 additional cholera cases have been reported from four local government areas (LGAs)–Gujba, Gulani, Damaturu and Fune. No new fatalities were reported.


Roundup of Global Volcanic Activity – New Activity for the week of 26 September – 2 October 2018

Kerinci | Indonesia : Based on satellite and wind model data, the Darwin VAAC reported that during 28-30 September and 2 October ash plumes from Kerinci rose to an altitude of 4.3 km (14,000 ft) a.s.l. and drifted SW and W.

Langila | New Britain (Papua New Guinea) : Based on analyses of satellite imagery and model data, the Darwin VAAC reported that on 29 September an ash plume from Langila rose to an altitude of 2.4 km (8,000 ft) a.s.l. and drifted NE.

Piton de la Fournaise | Reunion Island (France) : OVPF reported that the eruption at Piton de la Fournaise continued during 26 September-2 October, and tremor levels were stable. The cone continued to grow; one vent was active and ejected spatter. Lava flows were mostly confined to lava tubes, emerging 150-200 m downstream, S of the cone. During a field inspection on 29 September OVPF staff observed a small lava flow at the foot of the cone.

Sarychev Peak | Matua Island (Russia) : KVERT reported that a thermal anomaly over Sarychev Peak was visible in satellite images on 22 September. The Aviation colour Code remained at Orange.

Semisopochnoi | United States : AVO reported that during 19-25 September seismicity at Semisopochnoi remained elevated, alternating between periods of continuous and intermittent bursts of tremor. Tremor bursts at 1319 on 21 September and at 1034 on 22 September produced airwaves detected on a regional infrasound array on Adak Island; no ash emissions were identified above the low cloud deck in satellite data, and the infrasound detections likely reflected an atmospheric change instead of volcanic activity. The Aviation colour Code (ACC) remained at Yellow and Volcano Alert Level (VAL) remained at Advisory.

Soputan | Sulawesi (Indonesia) : PVMBG reported that increased seismicity at Soputan was notable on 2 October, characterized by an increased number of signals indicating emissions and avalanches (which began in September and mid-July, respectively), increased RSAM values, and a higher number of volcanic earthquakes (since September). Data from a thermal camera showed increased summit temperatures, indicating the presence of lava. The Alert Level was increased to 3 (on a scale of 1-4) on 3 October; residents and tourists were advised not to approach the craters within a radius of 4 km, with an additional expansion to 6.5 km in WSW direction due to increased risk from a breach in the crater rim. An eruption commenced at 0847 on 3 October, producing a dense ash plume that rose 4 km above the summit and drifted W and NW. Based on seismic data the event lasted six minutes. Events at 1044, 1112, and 1152 produced ash plumes that rose 2 km, 2.5 km , and 5 km above the crater rim, respectively. A thermal anomaly identified in satellite data significantly increased, and incandescent ejecta at the summit was clearly observed by residents. Avalanches of material traveled 2.5 km down the NE flank.

Veniaminof | United States : AVO reported that the eruption at Veniaminof continued during 26 September-2 October, as evidenced by nighttime incandescence recorded by the FAA web camera in Perryville (35 km S), elevated surface temperatures in thermal satellite data, and elevated tremor levels. A gas plume was occasionally visible during clear daytime conditions. On 26 September lava fountains, visible in webcam images, rose from a second vent located 75 m N of the vent producing lava flows. Minor ash emissions associated with lava fountaining possibly rose as high as km (15,000 ft) a.s.l. and quickly dispersed. The lava flow had traveled 1 km down the S flank of the summit cone by 1 October. The Aviation colour Code remained at Orange and the Volcano Alert Level remained at Watch.
