Ethiopia – The government in Ethiopia reports that unprecedented flooding caused by the overflow of the Awash River has displaced more than 144,000 persons in Afar Regional State. Flooding in the state has affected 240,000 people, demolished 105 schools, 200 rural roads, 6 bridges, and killed over 21,000 domestic animals. Flooding has also damaged around 60,000 hectares of crops and farmland.

New York Metronome Clock Displays Global Warming Deadline

The New York City Metronome digital clock in Manhattan has been reprogrammed to show the critical window within which global warming must be stopped. The display, called The Climate Clock, now indicates that the world has to stop global warming in about 7 years — otherwise, the impacts would be irreversible. The artists behind the project say that they have based their timing on calculations by the Mercator Research Institute on Global Commons and Climate Change in Berlin.

Roundup of Global Volcanic Activity – New Activity for the Week 16 September 2020 – 22 September 2020

Erta Ale | Ethiopia : Satellite data showed thermal anomalies in both of Erta Ale’s S and N pit craters in mid-August, though by 5 September only the N pit had anomalous temperatures.

Pavlof | United States : On 21 September AVO announced that the Volcano Alert Level for Pavlof was raised to Advisory and the Aviation Color Code was raised to Yellow. Seismicity had increased above background levels during the previous day and was characterized by ongoing tremor.

Sangay | Ecuador : IG reported a high level of activity at Sangay during 15-22 September. Seismicity was characterized by high levels of explosions, harmonic tremor, long-period earthquakes, and signals indicating emissions. Weather clouds sometimes prevented visual observations of the volcano, but the Washington VAAC and IG webcams recorded daily ash plumes that rose as high as 2 km above the summit and drifted in multiple directions. Pyroclastic flows descended the SE flank almost daily. An explosion at 0420 on 20 September was the largest such event in the recent months. Within 10 minutes several satellite images showed a large ash cloud rising 6-10 km above the summit; high-altitude parts of the cloud drifted E while lower parts drifted W. Servicio Nacional de Gestión de Riesgos y Emergencias (SNGRE) reported that 32 districts within the provinces of Chimborazo, Bolívar, Guayas, and Los Ríos were affected by ashfall. Authorities in the districts of Bucay and Cumandá restricted driving, the opening of businesses, and outdoor activities due to ashfall. The José Joaquín de Olmedo Airport in Guayaquil suspended its operations for seven hours to clean the runways. Ashfall was most significant in Chimborazo, particularly in the districts of Guamote, Alausí, Chunchi, Pallatanga, and Cumandá, with photos showing poor visibility and ashfall covering streets, cars, and houses. Ashfall significantly impacted agriculture fields. Authorities inspected the confluence of the Volcán River (SE flank) and Upano River, and observed significant deposits of tephra, some of which had damned the river and created an immense lagoon. Normally the Upano was about 25 m wide in that area but because of the deposits it was more than 250 m across and had almost no water in it. After the explosion, IG noted that activity returned to levels similar to previous months with ash plumes rising 1-2 km above the volcano during 20-22 September.
