Mexico – Tropical Storm Cristobal is already bringing damaging and deadly flooding to parts of Mexico and Central America and it is forecast to bring heavy rainfall over southern Mexico and parts of the Yucatan Peninsula this week. The Pacific Coast from Chiapas to Guatemala and El Salvador will also see heavy rainfall, which could cause widespread life-threatening flash floods and mudslides.

Uganda – Gardens, roads, and homes in five sub-counties of Dokolo district have been submerged by the rising water levels of Lake Kwania, making over a thousand families homeless. The people affected have moved to higher grounds as the devastating floods continue to wreak havoc in the district.

Bushmeat Hunting, Wildlife Declines, and Fish Supply in West Africa

The multibillion-dollar trade in bushmeat is among the most immediate threats to the persistence of tropical vertebrates, but our understanding of its underlying drivers and effects on human welfare is limited by a lack of empirical data. We used 30 years of data from Ghana to link mammal declines to the bushmeat trade and to spatial and temporal changes in the availability of fish. We show that years of poor fish supply coincided with increased hunting in nature reserves and sharp declines in biomass of 41 wildlife species. Local market data provide evidence of a direct link between fish supply and subsequent bushmeat demand in villages and show bushmeat’s role as a dietary staple in the region. Our results emphasize the urgent need to develop cheap protein alternatives to bushmeat and to improve fisheries management by foreign and domestic fleets to avert extinctions of tropical wildlife.

Volcanos

Roundup of Global Volcanic Activity – New Activity for the Week 27 May 2020 – 2 June 2020

Cleveland | Chuginadak Island (USA) : A small explosion at Cleveland was recorded at 1032 on 1 June and produced an ash plume that rose to 6.7 km (22,000 ft) a.s.l. and drifted S. The local geophysical stations and web camera were unavailable due to an ongoing network outage. AVO raised the Volcano Alert Level to Watch and the Aviation colour Code to Orange.

Ijen | Eastern Java (Indonesia) : PVMBG reported that on 29 May a gas explosion at Ijen generated a plume that rose 250-500 m above the surface of the lake. According to news articles two sulfur miners heard the explosion from under the water at 1230, which created 3-m-high waves in the lake; the miners ran but one tripped and fell into the lake. Search efforts were unsuccessful after three hours and, due to weather conditions and an increased amount of gas in the crater area, had to be suspended. PVMBG noted that patterns of various types of earthquakes did not indicate increased activity during 17 Janury-29 May. The temperature of the lake water fluctuated between 24.5 and 40.3 degrees Celsius. A lot of rain in the past few months increased the volume of the lake, possibly contributing to a disruption in the system, though these seasonal changes were within normal ranges at the volcano. The Alert Level remained at 1 (on a scale of 1-4), and residents and visitors were advised to not approach the crater rim or descend to the crater floor.

Karymsky | Eastern Kamchatka (Russia) : KVERT reported that a thermal anomaly over Karymsky was visible in satellite images during 23 and 25-28 May. Ash plumes were also identified and drifted 185 km SE and SW on 24, 26, and 28 May. The Aviation colour Code remained at Orange (the second highest level on a four-colour scale).
