Wildfires

Wildfires – USA

Very strong winds in Kansas and the panhandles of Texas and Oklahoma caused wildfires to spread very rapidly Wednesday. Blowing dust also caused severe visibility problems, and prompted the street lights to come on at noon in at least one area.

Oklahoma – The Cobb Fire in the Oklahoma panhandle caused the residents on the northwest side of Guymon to evacuate. Heat data from satellites at 1:55 p.m. CST indicated it had burned approximately 5,000 acres northwest of Guymon. The Oklahoma Forest Service said at 7 p.m. it had grown to about 10,000 acres.

Texas – The North 207 Fire in Carson County has burned an estimated 15,000 acres about 5 miles southeast of Borger. The Texas Forest Service said it has crossed Highway 152. The Parker Creek Fire started in Oldam County and spread into Hartley County southeast of Channing, about 14 miles south of Dumas. The TFS said at 6:08 p.m. it had burned 3,500 acres but satellite heat data indicates it could be larger.

Kansas – There are also numerous fires in western Kansas, also pushed by strong winds out of the west measured in at least one location at 100 mph. The New York Times reported that two fires merged in Russell and Ellsworth Counties in the central part of the state to form a massive blaze about 40 miles long, according to Eric Metzger, a meteorologist with the National Weather Service.

Volcanos

Roundup of Global Volcanic Activity – New Activity for the week 8 December – 14 December 2021

Awu – Sangihe Islands (Indonesia) : PVMBG reported that volcanic seismicity at Awu had increased beginning in October. Notably, the number of shallow volcanic earthquakes increased to 7-26 events per day from the previous maximum of 5 daily events. The number of deep volcanic earthquakes also increased. The Alert Level was raised to 2 (on a scale of 1-4) and the public was warned to stay 1 km away from the summit crater. The report also noted that no emissions nor any other surficial activity had been visible during 1 September-10 December, though weather sometimes hindered views.

Davidof – United States : Earthquake swarms either related to tectonic processes or volcanic unrest were recorded in the vicinity of Davidof during 8-10 December. The largest earthquake was a M 4.2 recorded at 1045 on 10 December. AVO raised the Aviation Color Code to Yellow and the Volcano Alert Level to Advisory due to the possibility of escalating volcanic unrest. Small earthquakes continued to be detected during 11-14 December, though at a lower rate and amplitude. Cloudy or mostly cloudy satellite and webcams views showed no volcanic activity.

Semeru – Eastern Java (Indonesia) : PVMBG reported that lava avalanches from the end of the 700-m-long lava flow on Semeru’s SE flank descended 500 m during 7-8 December. Lava avalanches were detected by the seismic network almost daily during 9-14 December, though weather conditions prevented visual confirmation. During 9-11 December crater incandescence was visible and gray-white ash plumes rose 300-1,000 m above the summit. White plumes rose as high as 1 km above the summit during 12-14 December. According to BNPB, the death toll from the 4 December collapse event rose to 48 by 13 December, 12 people were still missing, 21 were seriously injured, and 9,374 people were in 129 evacuation centers.
