Morocco – At least seven people were killed in flash floods in Morocco on Wednesday, following torrential rains in mountains in the south of the country near Taroudant, 600 kilometers (373 miles) south of Rabat, local authorities said.

Caribbean – Hurricane Dorian is gaining strength at it approaches Florida, with forecasters warning it could grow into a dangerous storm before it hits the east coast state. The hurricane has moved out into open waters after hitting Puerto Rico and the US Virgin Islands, where it caused power cuts and flooding in places.

Global Warming

Global Warming, Drought Drying Up Siberian Rivers, Cutting Off Far North

Global warming combined with the most serious drought in more than 30 years has led both to massive forest fires throughout Russia east of the Urals and to an abnormal drop in the water levels of major rivers, putting a halt to most river traffic and thus leaving many in the far north without the supplies they will need for the coming winter.

The hardest hit of the rivers is the Lena, 77 percent of whose route crosses through the rapidly melting permafrost; and the hardest hit of the regions are the northernmost portions of the Sakha Republic, many of which are beyond any rail or highway and depend on the river.

In Yakutsk, the republic capital, the water level of the Lena has fallen two and a half meters, leaving many vessels stranded in the mud and killing off the fish on which residents depend. As a result, Russian experts say, villages and towns will have to be supplied by air or be put at risk of depopulation.

If the river fleet dies, it is likely that almost all of those who moved into the region in Soviet and post-Soviet times will leave and the remaining population of indigenous peoples will be forced to return to a life of subsistence. If that occurs, a large part of what is shown as Russia on the map won’t be Russian at all.

Wildfires

Wildfires – Bolivia

Based on information received from the Ministry of Environment and Water (MMAyA) on August 26th, 521 thousand hectares are affected by fire forest in the Chiquitania region, Department of Santa Cruz, and 274 hectares of crops affected. Medias inform that the fires destroyed 738 thousand hectares.

Disease

Ebola – DR Congo

In the past week, from 19 August to 25 August, 77 new confirmed Ebola virus disease (EVD) cases, with an additional 54 deaths, have been reported from nine health zones in three affected provinces in the Democratic Republic of the Congo (DRC).

Tularemia – Sweden

In a follow-up on a report about two weeks ago, Swedish health officials are reporting a significant rise in tularemia cases since the end of July. As of Monday, about 560 human cases have been reported.

Malaria – India

Cases of falciparum malaria has spiked in Bareilly district in Uttar Pradesh state, with officials reporting 550 Plasmodium falciparum (PF) cases in the past month compared to about 150 in the first seven months of 2019.

According to reports, the less serious Plasmodium vivax (PV) malaria has accounted for more than 18,000 cases in the district year to date, including 5,600 in the past month. In addition dozens have been infected with both malaria strains.

Volcanos

Global Volcanic Activity – New Activity for the week of 21 August – 27 August 2019

Asamayama | Honshu (Japan) : JMA reported that at 1928 on 25 August a small eruption at Asamayama generated a grayish-white ash plume that rose 600 m above the crater rim and drifted E. Large blocks were also ejected from the crater. Minor ashfall was reported in Karuizawa Town, Nagano Prefecture, about 4 km E. The plume then turned white and continuous emissions rose 200 m during 25-26 August. The Alert Level remained at 2 (on a scale of 1-5).

Shishaldin | Fox Islands (USA) : AVO reported that during 21-28 August continuous, low-level tremor at Shishaldin was recorded by the seismic network and elevated surface temperatures were often visible in satellite images. The spatter cone in the crater had grown and partially filled the summit crater. NOAA scientists took video of the eruption during an overflight on 17 August and noted repetitive minor explosive activity within the summit crater. The Aviation colour Code remained at Orange and the Volcano Alert Level remained at Watch.

Stromboli | Aeolian Islands (Italy) : INGV reported that a paroxysmal explosive event at Stromboli began at 1216 on 28 August with a series of explosions likely from the Area C-S (South Central crater area). The event of strongest intensity occurred at 1217, generating an ash plume that rose more than 2 km above the crater area and a pyroclastic flow that traveled down the Sciara del Fuoco and several hundred meters out to sea. The report noted a similarity in intensity of the eruption to the 3 July paroxysmal event based on the seismic data.

Tangkubanparahu | Western Java (Indonesia) : PVMBG reported that during 19-25 August phreatic events at Tangkubanparahu’s Ratu Crater continued to produce sometimes dense gray-to-white plumes that rose as high as 200 m above the vent, and dense black ash plumes that rose as high as 180 m. Ashfall was localized around Ratu Crater. The seismic network recorded continuous tremor. The Alert Level remained at 2 (on a scale of 1-4), and the public was warned to stay 1.5 km away from the active crater.

Veniaminof | United States : AVO lowered the Volcano Alert Level to Normal for Veniaminof and the Aviation colour Code to Green on 25 August, noting that the volcano returned to background activity after low-level tremor was detected and a pilot saw steaming on 1 August.
