Elephant Culling in Zimbabwe

Zimbabwe is considering the mass killing of elephants for the first tie since 1988 to reduce the 100 000 strong population.

The Government of Zimbabwe, which has the world’s second largest elephant population after Botswana, maintains that the large number of animals is leading to the destruction of habitat needed by other species and an increasing number of dangerous human-elephant interactions.

Roundup of Global Volcanic Activity – New Activity for the Week 28 April 2021 – 4 May 2021

Asosan – Kyushu (Japan) : Volcanic tremor amplitude increased at Asoson at around 2100 on 2 May, prompting JMA to raise the Alert Level to 2 (on a scale of 1-5) at 2255. The public was warned to stay at least 1 km away from the crater. Sulfur dioxide emissions were low, at 200 tons per day on 3 May, and white steam plumes rose as high as 300 m above the crater rim.

Dieng Volcanic Complex – Central Java (Indonesia) : PVMBG reported that a phreatic eruption at the Sileri Crater lake (Dieng Volcanic Complex) occurred at 1825 on 29 April, ejecting rocks 200 m S and E and mud 400 m S and 300 m E. According to a news article a local road was temporarily closed because rocks (about 10 cm in diameter) from the eruption were scattered along the road and the mud made conditions slippery. The closest residents are 1 km away. The Alert Level remained at 1 (on a scale of 1-4), and the public was warned to stay 500 m away from the crater rim.

Karymsky – Eastern Kamchatka (Russia) : KVERT reported that a weak thermal anomaly over Karymsky was visible in satellite images during 22-23 and 29 April. The Aviation colour Code remained at Orange (the second highest level on a four-colour scale).

Piton de la Fournaise – Reunion Island (France) : OVPF reported that the eruption at Piton de la Fournaise continued during 28 April-4 May, though inclement weather obscured visual observations during most of the week. Both craters were active, producing lava flows that mainly traveled though lava tubes. Lava emerged from the end of the flow field, advancing E and setting fire to local vegetation. Minor inflation of the summit area was recorded. Lava fountaining was weak at the smaller vent to the SE during 3-4 May and a small lava pond occupied the crater of the larger cone, just NW at the higher elevation. On 4 May weak fountaining at the smaller cone occasionally ejected material just above the crater rim and the pond was active in the larger crater. The lava flow advanced another 180 m, reaching 1,500 m elevation. According to a news article two students in their 20s were found dead in the caldera on 22 April, near the active cones. The cause of death was not immediately known. The Alert Level remained at 2-2.
