New Jersey, USA – Wednesday’s severe thunderstorms with high winds and tropical downpours caused chaos on central Jersey roads. Emergency responders were busy assisting motorists caught in the floods. Flooding however, remained localized.

India – At least 16 people have died in Maharashtra as heavy rains and overflowing rivers swamped five districts, forcing authorities to move more than 140,000 people to safer places, a government official said on Wednesday. Rivers in the region were flooded as authorities released water from dams that had filled after some districts such as Kolhapur received as much as 670 mm (26.4 inches) of rainfall in a week.

Scotland – People in Edinburgh have been left reeling after significant flooding hit the city for the second time this summer. The first flooding reports came in from Leith and Restalrig, where portions of roads were left underwater and buses were diverted. Bankhead and Sighthill were also heavily hit, with Bankhead Crossing left underwater with collapsed manhole covers after a drain burst in the area. Train travelers were also affected with a number of railway lines under water.

Amazon Deforestation Shot Up by 278% Last Month

Deforestation of the Amazon rainforest increased by 278% in July 2019 compared with July 2018, resulting in the destruction of 870 square miles (2,253 square kilometers) of vegetation, new satellite data from the Brazilian National Institute for Space Research (INPE) show.

That’s an area about twice the size of the city of Los Angeles. And, while the forest still spans some 2.1 million square miles (5.5 million square km — just a little bit bigger than Mexico), the spike in tree loss is part of a dangerous trend.

Brazilian President Jair Bolsonaro, a climate change skeptic who vowed on the campaign trail to open more of the Amazon to various mining, logging and agricultural interests, despite environmental protections on the land called the report “a lie” and vowed to hire a private firm to monitor rain forest loss.

Record Number of Sea Turtle Nests in Florida, USA

“Amazing!” That’s the word turtle rescuers are using to describe the number of sea turtle nests found on Tampa Bay area beaches.

Sarasota and Manatee counties are seeing the highest number of sea turtle nests in 38 years. Mote Marine is tracking 5,063 nests along a 35-mile stretch of beach between Longboat Key and Venice. That includes 4,888 loggerhead nests, 170 green turtle nests, and five others.

Trump Administration Reauthorizes Wildlife-killing M-44 ‘Cyanide Bombs’

The Trump administration has reauthorized use of sodium cyanide in wildlife-killing devices called M-44s. These “cyanide bombs” received approval from the U.S. Environmental Protection Agency despite inhumanely and indiscriminately killing thousands of animals every year. They have also injured people.

The devices spray deadly sodium cyanide into the mouths of unsuspecting coyotes, foxes and other carnivores lured by smelly bait. Anything or anyone that pulls on the baited M-44 device can be killed or severely injured by the deadly spray.

Global Volcanic Activity – New Activity for the week of 31 July – 6 August 2019

Awu | Sangihe Islands (Indonesia) : The Darwin VAAC reported that on 4 August an ash plume from Awu was visible in satellite images rising to an altitude of 1.8 km (6,000 ft) a.s.l. and drifting N.

Karangetang | Siau Island (Indonesia) : PVMBG reported that beginning at 1858 on 20 July incandescent avalanches of material from Karangetang’s Main Crater traveled as far as 1 km W down the Pangi and Kinali drainages. By 22 July incandescent material had traveled another 500 m down the same drainages, and 1 km down the Nanitu and Beha drainages. Based on analyses of satellite imagery and model data, the Darwin VAAC reported that during 30-31 July intermittent discrete ash plumes rose to an altitude of 7.6 km (25,000 ft) a.s.l. and drifted W, and continuous ash emissions rose to 3 km (10,000 ft) a.s.l. A thermal anomaly was visible. On 5 August ash plumes rose to 3 km (10,000 ft) a.s.l. and drifted E; a thermal anomaly was again visible. The Alert Level remained at 2 (on a scale of 1-4).

Semisopochnoi | United States : AVO reported that during 31 July-6 August seismicity at Semisopochnoi remained elevated and was characterized by periods of weak, continuous tremor and discrete low-frequency earthquakes. Satellite images were mostly cloudy, though a possible steam plume was visible during 5-6 August. The Volcano Alert Level remained at Watch and the Aviation colour Code remained at Orange.

Shishaldin | Fox Islands (USA) : AVO reported that satellite images of Shishaldin acquired on 28 July showed a small spatter cone with lava flows in the summit crater. During 31 July-6 August continuous weak tremor was recorded by the seismic network and elevated surface temperatures were sometimes visible in satellite images. A small steam plume was observed in a few satellite and web camera images. The Aviation colour Code remained at Orange and the Volcano Alert Level remained at Watch.

Tangkubanparahu | Western Java (Indonesia) : PVMBG reported that an eruption at Tangkubanparahu’s Ratu Crater, recorded at 2046 on 1 August, generated a dense black ash-and-sediment-laden plume that rose about 180 m from the bottom of the crater, and light-coloured ash plumes mixed with water vapor that rose 200 m and drifted N and NE. The event lasted 11 minutes and 23 seconds based on seismic data. Ash and sediment fell in areas around the crater. Four eruptive events were recorded during the morning of 2 August, though ash emissions were not visually observed. The Alert Level was raised to 2 (on a scale of 1-4). A period of continuous ash emissions was recorded during 2-4 August.

Ulawun | New Britain (Papua New Guinea) : RVO reported that during 1-2 August white-to-grayish vapor plumes rose from Ulawun’s summit crater and drifted NW. Incandescence from the summit crater was visible at night and jetting noises were audible for a short interval. RSAM values fluctuated but peaked at high levels. During the night of 2-3 August crater incandescence strengthened and roaring noises became louder around 0400. An eruption began between 0430 and 0500 on 3 August; booming noises commenced around 0445. By 0600 dense light-gray ash emissions were drifting NW, causing ashfall in areas downwind including Ulamona Mission. Ash emissions continued through the day and grew from light to dark gray with time. The eruption intensified at 1900 and a lava fountain rose more than 100 m above the crater rim. A Plinian ash plume rose 19 km and drifted W and SW, causing ashfall in areas downwind such as Navo and Kabaya, and as far as Kimbe Town. The Darwin VAAC reported that the ash plume expanded radially and reached the stratosphere, rising to 19.2 km (63,000 ft) a.s.l. The plume then detached and drifted S and then SE. The Alert Level was raised to Stage 3 (the second highest level on a four-stage scale). The areas most affected by ash and scoria fall were between Navo (W) and Saltamana Estate (NW). Two classrooms at the Navo Primary School and a church in Navo collapsed from the weight of the ash and scoria; one of the classroom roofs had already partially collapsed during the 26 June eruption. Evacuees in tents as a result of the 26 June eruption reported damage. Rabaul town (E) also reported ashfall. Seismicity declined rapidly within two hours of the event, though continued to fluctuate at moderate levels. According to a news source flights in and out of Hoskins airport in Port Moresby were cancelled on 4 August due to tephra fall. The Alert Level was lowered to Stage 1. Small amounts of white and gray vapor were emitted from the summit crater during 4-6 August.

Veniaminof | United States : Low-level tremor at Veniaminof coincided with a pilot observation of a steam plume at 1230 on 1 August, prompting AVO to raise the Aviation colour Code to Yellow and the Volcano Alert Level to Advisory. On 2 August AVO noted that tremor had subsided, though low-level seismicity persisted at least through 6 August. Elevated surface temperatures were visible in satellite images. A small steam plume was also visible on 3 August.
