East Coast, USA – Hurricane Florence’s leading edge battered the Carolina coast Thursday, bending trees and shooting frothy sea water over streets on the Outer Banks, as the hulking storm closed in with 100 mph (160 kph) winds for a drenching siege that could last all weekend. Tens of thousands were without power. Winds and rain were arriving later in South Carolina, and a few people were still walking on the sand at Myrtle Beach while North Carolina was getting pounded. Forecasters’ European climate model is predicting 2 trillion to 11 trillion gallons of rain will fall on North Carolina over the next week, according to meteorologist Ryan Maue of weathermodels.com. That’s enough water to fill the Empire State Building nearly 40,000 times. More than 1.7 million people in the Carolinas and Virginia were warned to evacuate over the past few days, and the homes of about 10 million were under watches or warnings for the hurricane or tropical storm conditions.

Wildlife

Whaling Wins

A nearly two-decade effort to create a whale sanctuary across the southern Atlantic was shot down by pro-whaling nations at the fractious International Whaling Commission meeting in Brazil.

While 39 countries backed establishing a haven for the marine mammals, 25 voted against it, including Russia and pro-whaling Japan, along with commercial whaling nations Iceland and Norway. This caused the vote to fall short of the required three-quarters majority.

Environment

Desert Greening

Building solar and wind farms across the vast Sahara Desert could cause a lot more rain to fall throughout the arid region and allow more plants to grow.

The Sahara Solar Breeder Project aims to power half the world by 2050 with massive solar panel farms.

A team led by scientists from the University of Maryland also found that adding wind turbines to the mix would create rougher and darker land surfaces across the Sahara, causing more rain to fall.

Environment

Global Temperature Extremes

The week’s hottest temperature was 116 degrees Fahrenheit (46.7 degrees Celsius) in Hassi Messaoud, Algeria.

The week’s coldest temperature was minus 101.0 degrees Fahrenheit (minus 73.9 degrees Celsius) at Vostok, Antarctica.

Temperatures were tabulated from the more than 10,000 worldwide synoptic weather stations. The United Nations World Meteorological Organization sets the standards for weather observations, and provides a global telecommunications circuit for data distribution.

Roundup of Global Volcanic Activity – Ongoing Activity for the week of 5 September -11 September 2018

Aira | Kyushu (Japan) : JMA reported that there were two events and four explosions at Minamidake crater (at Aira Caldera’s Sakurajima volcano) during 3-10 September, with ash plumes rising as high as 1.7 km above the crater rim. Crater incandescence was occasionally visible at night. An explosion at 0304 on 9 September ejected material as far as 700 m. The Alert Level remained at 3 (on a 5-level scale).

Dukono | Halmahera (Indonesia) : Based on satellite data, wind model data, and notices from PVMBG, the Darwin VAAC reported that during 5-10 September ash plumes from Dukono rose to altitudes of 1.8-2.1 km (6,000-7,000 ft) a.s.l. and drifted SSE, SE, and E.

Ebeko | Paramushir Island (Russia) : Volcanologists in Severo-Kurilsk (Paramushir Island), about 7 km E of Ebeko, observed explosions during 31 August-7 September that sent ash plumes to 4.5 km (14,800 ft) a.s.l. Ash plumes were identified in satellite images drifting about 75 km N and S on 31 August and 4 September, and a thermal anomaly over the volcano was visible during 4-5 September. The Aviation Color Code remained at Orange (the second highest level on a four-color scale).

Karymsky | Eastern Kamchatka (Russia) : KVERT reported that a thermal anomaly over Karymsky was identified in satellite images on 31 August and 5 September. The Aviation Color Code remained at Orange (the second highest level on a four-color scale).

Kilauea | Hawaiian Islands (USA) : HVO reported that during 5-11 September weak lava activity at Kilauea’s Fissure 8 was characterized by occasional incandescence; during 9-10 September a small collapse pit formed and exposed hot material underneath. Seismicity and ground deformation remain low at the summit, and aftershocks from the M 6.9 earthquake in early May were located along faults on the south flank. The combined rate of sulfur dioxide emission from the summit and the LERZ (<1,000 tonnes/day) were lower than any time since late 2007. A series of small collapses at Pu’u ‘O’o Crater during 8-10 September generated visible brown plumes. The Volcano Alert Level remained at Watch and the Aviation Color Code remained at Orange.

Sabancaya | Peru : Observatorio Vulcanológico del Sur del IGP (OVS-IGP) and Observatorio Vulcanológico del INGEMMET (OVI) reported that explosions at Sabancaya averaged 17 per day during 3-9 September. Hybrid earthquakes were infrequent and of low magnitude. Gas-and-ash plumes rose as high as 3.5 km above the crater rim and drifted 50 km SW, E, and NE. The MIROVA system detected seven thermal anomalies, and on 3 September the sulfur dioxide gas flux was high at 2,380 tons/day. The report noted that the public should not approach the crater within a 12-km radius.

Sangay | Ecuador : Based on satellite images and wind model data, the Washington VAAC reported that during 5-8 and 10 September ash emissions from Sangay rose to 4.3-6.7 km (14,000-22,000 ft) a.s.l. and drifted at least 170 km W. A thermal anomaly was visible on 5 September.

Semeru | Eastern Java (Indonesia) : Based on analysis of satellite images and wind model data, the Darwin VAAC reported that during 6-7 September ash plumes from Semeru rose to an altitude of 4.3 km (14,000 ft) a.s.l. and drifted SW.

Sheveluch | Central Kamchatka (Russia) : KVERT reported that a thermal anomaly over Sheveluch was identified in satellite data during 1-7 September. The Aviation Color Code remained at Orange (the second highest level on a four-color scale).

Stromboli | Aeolian Islands (Italy) : INGV reported that during 3-9 September activity at Stromboli was characterized by ongoing Strombolian activity and degassing from multiple vents within the crater terrace. Explosions mainly from two vents (N1 and N2) in Area N (north crater area, NCA) and three vents (C, S1, and S2) in Area C-S (South Central crater area) occurred at a rate of 2-15 per hour. Low-to-medium-intensity explosions from the N1 vent ejected lapilli and bombs mixed with ash as high as 120 m. Explosions of variable intensity at the N2 vent ejected tephra 150 m high. Vent C produced gas emissions, and periodic low-intensity explosions ejected tephra 80 m high. Incandescent material from S1 jetted 120 m above the crater. Low-intensity explosions at S2 ejected tephra less than 80 m high.

Turrialba | Costa Rica : OVSICORI-UNA reported that passive gas-and-ash emissions from Turrialba were continuous during 27 August-5 September, with plumes rising 100 m above the vent. Emissions on 6 September were mostly gas, punctuated by small and sporadic ash plumes. At 1210 on 10 September an event produced an ash plume that rose 300 m above the crater rim and drifted NW.
