India – Barely a week before harvest season farmers in Bengal have been hit by floods following heavy rainfall in neighbouring states. Water level in several rivers such as the Ajay, Mayurakshi, Dwaraka and Kopai has risen alarmingly in Bengal following heavy rainfall in Bihar and Jharkhand over the past few days. Ferry services between East Burdwan and Nadia district have been suspended by the authorities. Movement of vehicles have been affected in parts of the Bharatpur-Kandi state highway in Murshidabad.

Anthrax in Namibia Spreads

In a follow-up on the anthrax outbreak in Bwabwata National Park in Namibia that killed scores of hippos, local media now report that approximately 20 dead buffalo were counted during an aerial assessment.

In a statement this week, the Environment Ministry said that the authorities are working around the clock to find an appropriate action to take. “We urge the public to refrain from touching and using the meat for consumption as this might be catastrophic,” they said.

Monkey Rescue

Scientists are scrambling in the wake of Hurricane Maria to save the more than 1,500 rhesus macaques that live on a small island off Puerto Rico.

The monkeys have been studied there since the 1930s, when they were imported from Southeast Asia.

Maria wiped out Cayo Santiago’s lush vegetation and wrecked the structures that provided fresh water.

Scientists from several universities have launched a relief effort to rebuild the research infrastructure and assure there is ample food for the monkeys until the island’s natural vegetation grows back.

Tainted Honey

A new study has found that most of the honey sampled from every continent except Antarctica during a recent five-year period was contaminated with a common class of bee-harming insecticides.

Researchers from the University of Neuchâtel in Switzerland found that 75 percent of the samples had “quantifiable amounts” of at least one of the neonicotinoids, which have also been linked to reduced colony growth and queen production in bumblebees.

The scientists say 86 percent of the samples collected in North America were contaminated, followed by 80 percent in Asia, 79 percent in Europe and 57 percent in South America.

Wildfires

Wildfires – California

Massive wildfires sweeping through California have now killed at least 31 people and damaged thousands of homes, businesses and other buildings, authorities said. Firefighters were still battling 21 large wildfires in multiple counties as of Thursday morning. Intensified by strong winds, the flames have charred more than 190,000 acres of land, damaged or destroyed at least 3,500 structures and forced more than 20,000 residents to evacuate, according to the California Department of Forestry and Fire Protection.

Roundup of Global Volcanic Activity – Ongoing Activity for the week of 4 October – 10 October 2017

Aira | Kyushu (Japan) : JMA reported that during 2-10 October there were 19 events detected at Showa Crater (at Aira Caldera’s Sakurajima volcano), three of which were explosive. Plumes rose as high as 1.6 km above the crater rim. An explosion on 5 October ejected material as far as 800 m. The Alert Level remained at 3 (on a 5-level scale).

Bezymianny | Central Kamchatka (Russia) : On 6 October KVERT reported that a thermal anomaly at Bezymianny was identified in satellite images during 1-2 and 4-5 October, and that lava probably continued to flow down the W flank of the dome. The Aviation Color Code was lowered to Yellow (the second lowest level on a four-color scale).

Cleveland | Chuginadak Island (USA) : AVO reported that no significant activity at Cleveland was observed in seismic or infrasound data during 4-10 October, though elevated surface temperatures identified in satellite data on 6 October suggested that the lava dome in the summit crater (first noted on 30 September) continued to grow. Elevated surface temperatures were identified during 8-9 October. The Aviation Color Code remained at Orange and the Volcano Alert Level remained at Watch.

Dukono | Halmahera (Indonesia) : Based on analyses of satellite imagery, model data, and notices from PVMBG, the Darwin VAAC reported that during 4-10 October ash plumes from Dukono rose to altitudes of 1.8-2.1 km (6,000-7,000 ft) a.s.l. and drifted N, NW, W, and SW. Ash plumes drifted 140-170 km on 8 October.

Ebeko | Paramushir Island (Russia) : Based on observations by volcanologists in Severo-Kurilsk (Paramushir Island), about 7 km E of Ebeko, explosions during 29-30 September and 1 and 5 October generated ash plumes that rose 1.5 km (4,900 ft) a.s.l. The Aviation Color Code remained at Orange (the second highest level on a four-color scale).

Fuego | Guatemala | 14.473°N, 90.88°W : CONRED and INSIVUMEH reported that during 4-6 October increased explosive activity (8-12 explosions per hour) at Fuego generating ash plumes that rose as high as 1.3 km above the crater. Ash plumes drifted more than 20 km S, SW, and W; ashfall was reported in areas downwind including Panimaché I and II (8 km SW), Santa Sofía (12 km SW), Morelia (9 km SW), and El Porvenir. Incandescent material rose 300 m above the crater, and avalanches of material traveled as far as 1.5 km W down the Seca (Santa Teresa) ravine and SSW down the Ceniza ravine. Shockwaves vibrated local structures. An average of 4-6 explosions per hour were detected during 7-8 October. Ash plumes rose around 1 km and drifted 12 km W, NW, and N. Incandescent material was ejected 150 m above the crater, causing avalanches that were confined to the crater. Ash fell in local communities including San Pedro Yepocapa (8 km N), Sangre de Cristo (8 km WSW), and La Soledad. Vulcanian explosions during 8-9 October produced ash plumes that rose 1 km and drifted 15 km SW, W, and NW, again causing ashfall in Panimaché, Santa Sofía, Morelia, El Porvenir, San Pedro Yepocapa, and Sangre de Cristo. Block avalanches traveled 2 km down the flanks.

Karymsky | Eastern Kamchatka (Russia) : KVERT reported that an ash cloud was identified in satellite images drifting about 85 km ENE from Karymsky on 3 October. The Aviation Color Code was raised to Orange (the second highest level on a four-color scale).

Kilauea | Hawaiian Islands (USA) : During 4-10 October HVO reported that the lava lake continued to rise, fall, and spatter in Kilauea’s Overlook crater. Webcams recorded incandescence from long-active sources within Pu’u ‘O’o Crater and from a small lava pond in a pit on the W side of the crater. The 61G lava flow, originating from a vent on Pu’u ‘O’o Crater’s E flank, continued to enter the ocean at Kamokuna although the plume at the entry was weaker. Surface lava flows were active above and on the pali, and on the coastal plain.

Langila | New Britain (Papua New Guinea) : Based on analyses of satellite imagery and model data, the Darwin VAAC reported that on 4 October a minor ash emission from Langila rose 1.8 km (6,000 ft) a.s.l. and drifted N.

Reventador | Ecuador : During 3-10 October IG reported a high level of seismic activity including explosions, long-period earthquakes, harmonic tremor, and signals indicating emissions at Reventador. Steam, gas, and ash plumes rose sometimes higher that 1.1 km above the crater rim and drifted mainly NW, W, and SW. Incandescent blocks rolled as far as 800 m down the flanks. Weather clouds sometimes prevented visual observations.

Rincon de la Vieja | Costa Rica : OVSICORI-UNA reported that at 1048 on 9 October a small eruption at Rincón de la Vieja produced a plume that rose 700 m above the crater rim.

Sabancaya | Peru : Observatorio Vulcanológico del Sur del IGP (OVS-IGP) and Observatorio Vulcanológico del INGEMMET (OVI) reported that explosive activity at Sabancaya slightly declined; there was an average of 42 explosions recorded per day during 2-8 October. The earthquakes were dominated by long-period events, with fewer numbers of signals indicating emissions and hybrid events. Gas-and-ash plumes rose 3.5 km above the crater rim and drifted no more than 40 km N, NW, and W. The MIROVA system detected 10 thermal anomalies. The report warned the public not to approach the crater within a 12-km radius.

Sangay | Ecuador : In a special report from 4 October IG stated that the current eruption at Sangay which began on 20 July continued, and that the activity had not changed significantly during the previous two months. Activity was characterized by explosions at the central vent and lava from the Ñuñurco lava dome flowing down the E and ESE flanks. On each day during the previous week there were about 65 explosions, 25 long-period events, and a few harmonic tremor signals. Ash plumes rose 1 km above the crater rim and caused ashfall in areas to the W and NW (Culebrillas and Licto (35 km NW)).

Sheveluch | Central Kamchatka (Russia) : KVERT reported that a thermal anomaly over Sheveluch was identified daily in satellite images on 2 and 5 October. The Aviation Color Code remained at Orange.

Sinabung | Indonesia : Based on observations by PVMBG and BMKG, webcam and satellite images, and model data, the Darwin VAAC reported that during 4-5 and 7-9 October ash plumes from Sinabung rose 3-5.8 km (10,000-19,000 ft) a.s.l. and drifted in multiple directions.

Turrialba | Costa Rica : OVSICORI-UNA reported that an event at Turrialba at 0815 on 6 October produced a plume that rose 50 m above the crater rim and drifted NW. An event at 1040 on 9 October generated a plume that rose 200 m and drifted NW.
