England – In the East Midlands, shops, homes and streets were flooded as parts of the area were deluged in a short space of time. It followed storms on Tuesday, which saw lightning strikes damage homes and cause buildings, including Walsall Manor Hospital, to flood. The Met Office warned of potential flooding to homes and businesses as well as possible “lightning strikes, hail or strong winds”. On Wednesday afternoon trains were disrupted between Birmingham New Street and Whitlocks End due to heavy rain flooding the railway line. There were also reports of roads being flooded across the region.

Global Warming

Burning coal in Siberia ignited by volcanic eruptions led to catastrophic global warming that caused the Earth’s most severe extinction event 250 million years ago

Burning coal may have been to blame for a catastrophic global warming event 250 million years ago that wiped out 96 per cent of marine and 70 per cent of terrestrial species on Earth.

For years it has been attributed to extensive volcanic eruptions in Siberia over two million years, which belched tons of carbon dioxide into the atmosphere.

But now scientists have uncovered evidence that the boiling lava ignited coal seams buried in the Earth, which released more greenhouse gases and exacerbated the disaster.

Volcanos

Roundup of Global Volcanic Activity – New Activity for the Week 10 June 2020 – 16 June 2020

Cleveland | Chuginadak Island (USA) : AVO reported that unrest at Cleveland likely continued during 10-16 June, though no activity was identified in cloudy satellite images nor detected by regional geophysical networks. AVO noted that local seismic, infrasound, and web camera data are unavailable due to an equipment failure, Cleveland continued to be monitored with regional seismic and infrasound stations on nearby islands, along with lightning and satellite data capabilities. The Volcano Alert Level remained at Watch and the Aviation Color Code remained at Orange.

Karymsky | Eastern Kamchatka (Russia) : KVERT reported that a weak thermal anomaly over Karymsky was identified in satellite images during 10-11 June. The Aviation Color Code remained at Orange (the second highest level on a four-color scale).

Makushin | Fox Islands (USA) : AVO reported that over a period of several hours on 15 June there were two earthquakes in the vicinity of Makushin that were greater than M 4 and one greater than M 3. The events were located about 11 km SE of the summit at a depth of about 8 km, and felt in Unalaska (14 km E). Numerous smaller earthquakes were recorded, though not felt by Unalaska residents. AVO noted that the earthquakes represented a departure from background levels and were possibly indicative of volcanic unrest; the Aviation Color Code and Volcano Alert Level were respectively raised to Yellow and Advisory. The report noted that aftershocks were continuing.

Sangay | Ecuador : IG reported that for the past year, activity at Sangay is centered at two summit vents: the Central Crater which produced ash-and-gas emissions and the Ñuñurcu dome (located 190 m SSE of Central Crater) which effused lava. Lava, pyroclastic flows, and collapsed material were channeled down the Volcán River drainage on the SE flank. Activity at Sangay intensified during 8-9 June with lava-flow collapses, pyroclastic flows on the SE flank that reached the Upano River, and significant ash emissions that drifted W. No variation in seismic data was noted prior to a period of increased activity. A comparison of webcam images from 2 September 2019 and 10 June 2020 showed that the drainage had widened, deepened, and lengthened. In recent weeks ash plumes had risen as high as 2.9 km above the crater rim and had been carried farther by strong winds. Ashfall was reported in the provinces of Chimborazo, Bolívar, Guayas, Santa Elena, Los Ríos, and Morona Santiago. Activity slightly increased during 11-12 June, characterized by ash-and-gas plumes rising higher (1.5-2.8 km above the crater rim) and drifting farther (over 600 km W and SW), and an increased number of thermal anomalies on the SE flank from intensified lava effusion. A pulse of increased seismic activity was also detected. Ashfall was additionally reported in the provinces of Tungurahua and Cotopaxi.
