Kenya – Heavy rains kill four people in Nairobi as floods cause havoc across the city. A six-storey residential building collapsed under the heavy rain in the Kenyan capital late on Friday, killing at least three people.

Argentina – Water levels in the flood-hit Argentine town of Villa Paranacito have risen so much that the best way for residents to commute is by boat. The floods have swamped the soy crop causing substantial losses to farmers and the local economy.

Disease

Zika Virus – Puerto Rico

Puerto Rico announced Friday that it has recorded the first Zika-related U.S. death amid an outbreak of the mosquito-borne virus in the U.S. territory.

Officials said the unidentified man recovered from initial Zika symptoms, but then developed a condition in which antibodies that formed in reaction to the Zika infection started attacking blood platelet cells. He died after suffering internal bleeding in less than 24 hours after seeking help at a health centre.

Bovine Disease – India

Outbreak of Haemorrhagic septicaemia (HS), an acute, fatal, septicaemic disease of cattle and water buffaloes in the districts of Peren and Dimapur is under control, according to the Animal Husbandry and Veterinary Department. At least 90 % of the disease outbreak among the buffaloes has been brought under control.

The disease had affected six villages under Peren district namely Punglwa, Gaili, Ngwalwa, Heninkunglwa, Dunki-Lamhai and Saijang. An estimate of 314 buffaloes succumbed to the disease within a span of one month.

Farmers in the said areas are fully dependent on the buffaloes for ploughing the rice fields. There more than 1500 buffaloes owned by the six villages. With the outbreak of HS, around 20% of the buffaloes have already died.

Wildfires

Wildfires – Ireland

The Irish Wildlife Trust (IWT) has voiced concerns about the amount of wildfires taking place. The organisation said it received reports of 19 separate wildfires across Ireland over the 10 days from 16-26 April.

Some 11 of the fires took place in areas protected for nature conservation, with Killarney National Park, the Slieve Aughty mountains, the Blackstairs mountains, and the Beara peninsula in Cork all being affected.

The organisation said repeated fires across Ireland’s uplands have become an annual feature and are “causing tremendous damage to wildlife, landscape, water and air”.

Volcanos

Roundup of Global Volcanic Activity

Kliuchevskoi (Kamchatka): As had been previously suggested, the volcano’s most recent eruptive phase had become both effusive and explosive: in addition to ash-generating strombolian explosions from the summit vent, a new, but short-lived lava flow appeared during 23 or 24 April and descended approx. 800 m on the south-eastern flank of the volcano (along the Apakhonchich ravine). It seems that the lava flow remained active at least until Tue (26 April) according to KVERT’s daily reports and images from the local observatory, but seems to have stopped by now; glow is no longer visible on clear webcam imagery from yesterday and today. A significant, continuous steam plume suggests that mild explosive activity continues.

Ruapehu (North Island): An earthquake swarm has been occurring at the volcano since 26 April. According to Geonet, such seismic swarms indicating small rock-fracturing events have been rare at the volcano in recent years. Ruapehu’s typical seismic activity is rather dominated by events reflecting internal circulation of fluids such as tremor.

White Island (New Zealand): A small phreatic explosion occurred inside the main crater of the volcano on the evening of 27 April around 21:50 local time, Geonet reported. The volcanic alert level was raised to 3 and aviation color code to Orange. Since the eruption, the volcano has returned to quiet / normal activity and the alert level was again lowered to 2 (although aviation color code remains orange for the time being as other explosions could occur).

Cleveland (Aleutian Islands, Alaska): The Alaska volcano observatory lowered the alert level to yellow, after no more activity has been observed at the volcano since the small explosion on 16 April. “Seismicity returned to low levels within an hour of the explosion, and there have been no infrasound (pressure sensor) signals detected. Recent satellite views indicate that the August 2015 lava dome is gone and has been replaced with a small cinder cone within the summit crater. Based on seismic levels remaining low since the eruption, and no observations or reports of continued eruptive activity, AVO is reducing the Aviation Color Code to YELLOW and the Volcano Alert Level to ADVISORY.”
