Update on polio in central Africa – polio confirmed in Equatorial Guinea, linked to outbreak in Cameroon

In Equatorial Guinea, three new wild poliovirus type 1 (WPV1) cases have been reported on 14 April 2014, the first polio in the country since 1999. Genetic sequencing indicates these cases are linked to an ongoing WPV1 outbreak in Cameroon which has subsequently been detected in Equatorial Guinea. The cases had onset of paralysis on 28 January 2014, 19 January 2014 and 24 March 2014, from Centro Sur, Bioko Norte and Litoral. Outbreak response in Equatorial Guinea is currently being planned, including National Immunization Days (NIDs) with bivalent oral polio vaccine (OPV) on 21-24 April 2014. An estimated 40% of children are fully immunized against polio in the country.

Roundup of Global Volcanic Activity

Etna (Sicily, Italy): Occasional weak explosions continue at the New SE crater: two very small events were observed today at 03:45 and 04:05 (local time).

Kilauea (Hawai’i): (21 Apr) Here on Kilauea over the past week we have seen the lava lake at the summit rise and drop several times! This is due to the several DI tilt events that have occured. Gas emissions continued to be elevated at the summit as well. On the East Rift Zone, near Pu’u ‘O’o we have seen no major changes – Spatter cones on the floor of Pu’u ‘O’o crater displayed strong glow and the lava level of the circulating lava pond was elevated within the collapsed northeast spatter cone. USGS Webcams recorded continued activity from the small tube breakout that started Saturday morning and at the flow front.

Big meteorite strikes in Russia – again!

Unlike the celestial object that exploded over the town of Chelyabinsk last year, this recent one injured no one on the ground according to local reports.

Video has emerged of a huge meteorite streaking through the sky near the northern Russian city of Murmansk. The moment was captured by many residents as the white-blue light of the meteorite moved through the sky in the early hours of Saturday morning.

Some 500 meteorites reach Earth each year, though many are small and are not spotted.

Dengue Fever Outbreaks

Dengue Fever Outbreak Reported In Mozambique’s Northern Cabo Delgado Province

Sixteen dengue fever cases have been confirmed and another nine suspected in the city of Pemba, the capital of the northern Cabo Delgado Province in the southeastern African country of Mozambique.

Health officials attribute the outbreak of the mosquito-borne viral disease to the heavy rains in the province in recent months while people already carry the virus.

Dengue fever outbreak imminent in Nigeria

Nigeria is in danger of Dengue fever outbreak, another deadly fever in the class of Ebola virus disease, said to be transmitted by two types of mosquitoes now rife in the country.

Dr Adeniji, Director of World Health Organisation (WHO) National Polio Laboratory, Department of Virology, University of Ibadan (UI), named the mosquitoes as Aedes aegypti mosquito (yellow fever mosquitoes) and Aedes albopictusis (tiger mosquitoes), adding that the mosquitoes had been observed in Nigeria and that they spent their lifetime in or around homes.

According to Dr Adeniji, “there is no house that these mosquitoes are not present, including big hotels. We have all the four stereotypes of Dengue fever in Nigeria. Although not all mosquitoes are infected with Dengue virus, if bitten by an infected one, it will spread the virus.”

The expert said these mosquitoes, black and tiny, with white patches on it, look alike, adding that a recent case people thought was Ebola virus disease turned out be a case of Dengue fever.

Roundup of Global Volcanic Activity

Fuego volcano (Guatemala): strong explosions, increase of activity. Activity at the volcano continues to be elevated and increased yesterday, prompting INSIVUMEH to issue a special bulletin yesterday, in which the agency warns that a possible new paroxysm could occur in the near future. The volcano observatory reported moderate to strong explosions with plumes up to 1 km height and drifting 12 km, causing ash falls ash on the villages Panimaché, Morelia, Santa Sofia and others. This activity was also accompanied by increased tremor. As of today, it has decreased again, but remains high, and the occurrence of another paroxysm is still a potential scenario. In this case, strong explosions and associated ash plum rising significantly more than 1-2 km above the summit, lava flows and potentially pyroclastic flows on the southern slopes could be expected.

Dukono volcano (Halmahera, Indonesia) activity update Explosions that are strong enough to leave ash plumes visible on satellite data continue to occur almost every day. This morning, VAAC Darwin reported an ash plume at 8,000 ft (2.4 km) altitude.

Merapi volcano (Central Java, Indonesia): powerful explosion yesterday morning A new explosion occurred at the volcano early yesterday morning (Sun, 20 April), at around 4:25 am local time. VAAC Darwin reported an ash plume rising to approx. 30-35,000 ft (9-11 km) altitude and drifting NWN, and raised the aviation alert level to red. VSI in turn has not changed the alert status (currently at 1, “normal”, out of 4) of the volcano because it seems that scientists think that the explosion was phreatic in nature, i.e. not caused by fresh magma, but interaction of penetrating (rain) water into the hot rocks in the upper conduit system of the volcano. No unusual seismic activity is currently detected at Merapi. The explosion was not observed during the nighttime, but heard in several kilometres distance away, and ash falls occurred in villages around the volcano, prompting residents to wear dust masks and clean up roofs and streets from ash.

Wildfires in Siberia

Russian Emergency Situations Ministry uses 30 aircraft to extinguish wildfires in Far East, Siberia spokesperson Alexander Drobyshevsky said on Saturday.

As of Saturday morning, in Russia continue 103 wildfires at 27,412 hectares, including big 26 wildfires in the Far East and in Siberia,” he said.

On Friday, 147 new fires began at 12,509 hectares, and 150 were extinguished at 5,437 hectares. Emergency situation has been introduced in the regions with most complicated situations – in the Amur region, in the Maritime and Baikal territories, he said.

The space monitoring has located 1,587 thermal points, where 1,362 thermal point were confirmed later on. Over 800 specialised vehicles, 30 aircrafts and 3,247 people are involved in extinguishing of the wildfires. Besides, 100 rescuers with knapsack fire extinguishers are working on the sites.

“On Friday, the aviation made 17 flights, 107 droppings of 1,175 litres of water.”

EMERCOM is using in the Far East and Siberia planes Be-200 and Il-76, and helicopters Mi-8 and Mi-26.

More than 100 forest fires were registered in the Far East during the day.

In the Far East region 111 forest fires were registered per night, 48 of which were eliminated, according to Department of Forestry.

Roundup of Global Volcanic Activity

Momotombo (Nicaragua): INETER reported that the shore of Lake Managua retreated in some areas close to the epicenters of the recent earthquakes. Residents from the area Xiloá-Apoyeque, located about 2 km east of Comarca el Marañonal (at km 17 on the Xiloá highway) observed that the beach retreated for 16 meters on a strech of 500 m length. This regression corresponds to a drop in lake level by 40 cm, but could also be a result of uplift of this area by the same amount. The latter seems a more plausible explanation, given that it appears that the lake shore only regressed in this area. As of 19 April, seismic activity has continued to show a gradual decrease as aftershocks from the 10 and 11 April quakes become less and less frequent.

Ubinas (Peru): A relatively strong ash emission was reported from last night (19:00 local time), inferred by seismic and infrared data. VAAC Buenos Aires issued an alert of an ash plume at 28,000 ft (8 km) altitude drifting SE. MODIS hot spot data show an increased thermal anomaly present at the volcano’s summit, suggesting that the amount of lava present there has grown.
