India – Death Toll Rises – A series of powerful super storms that tore through India this week have killed 143 people, as officials warned on Friday the death toll could rise with more extreme weather expected. A deadly dust storm claimed 121 lives in Uttar Pradesh, Rajasthan, Uttarakhand and Punjab, while an electric storm, in which lightning struck an estimate 40 000 times, left 21 people dead in the country’s south. Thousands of people in Uttar Pradesh and Rajasthan had their homes destroyed by the freak storm, which was packing winds of up to 130km/h. A total of 76 people were killed in Uttar Pradesh, India’s most populous province, the state disaster management department said, with Agra district one of the worst hit areas, with at least 43 people killed.

British Columbia, Canada – Rivers and creeks continue to swell across B.C. as emergency officials warn flooding conditions could worsen next week. As of Thursday, 12 evacuation orders and 11 evacuation alerts were in place across the province. In the small recreational community of Tulameen, about 26 kilometres northwest of the town of Princeton, residents have been asked to be ready to leave on short notice.


Simian Revenge

A Sudanese farmer was rescued from a savage attack by a monkey, said to be the father of a young monkey the farmer killed years ago.

Khartoum’s SudaNow reports the Central Darfur farmer’s wife was able to beat the attacking primate to death as it was biting her husband’s thighs and legs.

The magazine reports monkeys once dug up seeds the farmer had planted until he chased them away about five years ago, killing the assaulting monkey’s offspring in the process.

Locals say they have witnessed monkeys stalking their enemies for decades after being wronged.

Elderly Arachnid

The world’s oldest known spider was killed at the age of 43 by a wasp attack in Western Australia.

Scientists at Curtin University said the trapdoor spider was the subject of a long-term study and outlived the previous record-holder by 15 years, mainly from living her entire life in one burrow.

“We’re really miserable about it,” lead researcher Leanda Mason told The Telegraph. “We were hoping she could have made it to 50 years old.”

Trapdoor spiders ambush small prey that have the misfortune of passing by their burrows.


Global Temperature Extremes

The week’s hottest temperature was 122 degrees Fahrenheit (50.0 degrees Celsius) in Newabshah, Pakistan.

The week’s coldest temperature was minus 94.0 degrees Fahrenheit (minus 70.0 degrees Celsius) at Vostok, Antarctica.

Temperatures were tabulated from the more than 10,000 worldwide synoptic weather stations. The United Nations World Meteorological Organization sets the standards for weather observations, and provides a global telecommunications circuit for data distribution.


Dengue fever – Reunion

In a follow-up on the dengue epidemic on the Indian Ocean island of Reunion, French health officials report an additional 298 biologically confirmed and probable cases in the past week, bringing the total to 2,119 cases for the year. Fifty-nine people have required hospitalization for their illness to date.

Kenyan Rains Raise Risk of Large-Scale Disease Outbreak

Heavy rains and flooding in Kenya compounded a cholera outbreak and a chikungunya epidemic and increased the risk of large-scale spread of the diseases, the United Nations said. A cholera outbreak in 15 of Kenya’s 47 counties has left at least 55 people dead, the agency said. The flooding also heightened the risk of disease including malaria, chikungunya and dengue fever.

Legionnaires’ Disease – Melbourne, Australia

Two men are in intensive care fighting Legionnaires’ disease while a third is also in hospital connected to a Gladstone Park outbreak.

The Department of Health issued a warning over the outbreak today after all three men became ill following visits to the Airport West and Gladstone Park Shopping Centres between April 20 and 26. Health officers are now investigating cooling towers in the northern suburb area to determine the cause of the outbreak.


Hawaii’s Kilauea Volcano Erupts Dramatically After a 5.1-Magnitude Quake

After authorities had warned for several days of an impending eruption, Hawaii’s Kilauea volcano delivered Thursday. White clouds of steam and volcanic gases rose high in the sky above the southeastern part of Hawaii Island.

A river of destructive lava flowing underground was released around 4:30 p.m. local time into a residential subdivision, prompting people in the area to pack their belongings and abandon their homes.

On some streets the bright red-orange lava could be seen spurting out of cracks in the ground. The deafening sound of grinding rocks filled the air and “white, hot vapor and blue fumes emanated” from the cracking.


Roundup of Global Volcanic Activity – Ongoing Activity for the week of 25 April – 1 May 2018

Agung | Bali (Indonesia) : PVMBG reported that at 2245 on 30 April an event at Agung generated an ash plume that rose 1.5 km above the crater rim and drifted SW. Seismicity was dominated by low-frequency earthquakes related to gas-and-steam emissions. The Alert Level remained at 3 (on a scale of 1-4) and the exclusion zone continued at a 4-km radius.

Aira | Kyushu (Japan) : JMA reported that there were nine events and 30 explosions at Minamidake crater (at Aira Caldera’s Sakurajima volcano) during 20 April-1 May. Tephra was ejected as far as 1.3 km from the crater, and ash plumes rose as high as 3.3 km above the crater rim. Crater incandescence was visible at night on 20, 23, 26, and 30 April. The Alert Level remained at 3 (on a 5-level scale).

Dukono | Halmahera (Indonesia) : Based on analyses of satellite imagery, wind model data, and notices from PVMBG, the Darwin VAAC reported that during 25 April-1 May ash plumes from Dukono rose to altitudes of 1.5-2.1 km (5,000-7,000 ft) a.s.l. and drifted NE, E, and SE.

Ebeko | Paramushir Island (Russia) : Volcanologists in Severo-Kurilsk (Paramushir Island), about 7 km E of Ebeko, observed explosions during 21 and 25 April that sent ash plumes as high as 2.5 km (8,200 ft) a.s.l. The Aviation Color Code remained at Orange (the second highest level on a four-color scale).

Kikai | Japan : JMA reported that the number of volcanic earthquakes at Satsuma Iwo-jima, a subaerial part of Kikai’s NW caldera rim, was low during 20-26 April. White plumes rose as high as 700 m above the Iwo-dake lava dome; incandescence from the crater had not been visible since 12 April. During field surveys on 25 and 26 April observers noted a slight expansion of a thermally anomalous area compared to 24-25 March observations, and a decrease in sulfur dioxide flux from 600 tons/day on 24 March to 300 tons/day. The Alert Level was reduced to 1 (on a 5-level scale) on 27 April.

Pacaya | Guatemala : INSIVUMEH and CONRED reported that during 27-28 April seismicity at Pacaya had increased, and moderate-to-strong explosions ejected material as high as 150 m above the crater rim. Lava originating from the 2010 fissure traveled about 500 m NW, towards Cerro Chino. The report noted that ejected material has filled the crater.

Popocatepetl | Mexico : CENAPRED reported that each day during 25 April-1 May there were 63-114 steam and gas emissions from Popocatépetl, often containing ash. Incandescence from the crater was visible at night. As many as five explosions per day were recorded during 25-29 April, with resulting eruption plumes rising around 1 km above the crater rim. The Alert Level remained at Yellow, Phase Two.

Reventador | Ecuador : During 24 April-1 May IG reported a high level of seismic activity including explosions, long-period earthquakes, harmonic tremor, and signals indicating emissions at Reventador. Steam, gas, and ash plumes sometimes rose higher than 1 km above the crater rim and drifted NE, NW, and W. On 27 April incandescent blocks rolled as far as 800 m down the flanks, and a small pyroclastic flow traveled down the E flank.

Sabancaya | Peru : Observatorio Vulcanológico del Sur del IGP (OVS-IGP) and Observatorio Vulcanológico del INGEMMET (OVI) reported that explosive activity at Sabancaya was similar to the previous week; explosions averaged 22 per day during 23-29 April. Seismicity was dominated by long-period events and signals indicating emissions. Gas-and-ash plumes rose as high as 2 km above the crater rim and drifted 30 km NE and SE. The report noted that the public should not to approach the crater within a 12-km radius.

Sheveluch | Central Kamchatka (Russia) : KVERT reported that a weak thermal anomaly over Sheveluch was identified in satellite images during 21 and 23-25 April. The Aviation Color Code remained at Orange.

Stromboli | Aeolian Islands (Italy) : INGV reported that on 24 April an intense explosive sequence occurred at vents on Stromboli’s south-central crater terrace area. The first explosion, recorded at 1105, ejected an abundant amount of ash, incandescent material, and large blocks to a height of 250 m that fell onto the summit area and along the Sciara del Fuoco. An explosive event at 1106 was characterized by modest lava fountaining. The last event, recorded at 1110, ejected pyroclastic material, though it was less intense than the first. An ash plume from the sequence quickly dispersed SE.

Suwanosejima | Ryukyu Islands (Japan) : Based on JMA notices and satellite data, the Tokyo VAAC reported an explosion at Suwanosejima on 24 April, and that events during 27-29 April produced plumes that rose 1.2-2.1 km (4,000-7,000 ft) a.s.l. and drifted in multiple directions.
