Thailand – Torrential rain on Tuesday night triggered flash floods that hit parts of the five southern provinces of Krabi, Surat Thani, Songkhla, Phatthalung and Yala yesterday, affecting thousands of people. In Krabi, the downpours caused flash floods from 3am onward in several communities in Khao Phanom district. In Yala, more than 500 houses in the flood-prone zones of this district were flooded yesterday. Several roads, at least 40 houses and more than 500 rai of farmland in three tambons of this district — tambon Phru Tiaw, tambon Khao Phanom and tambon Khao Din — were affected by the sudden flooding. Schools in affected areas were closed for two days.

Wildlife

Seahorses Return

A breeding population of short-snouted seahorses has been discovered living in England’s River Thames in what biologists say is proof the once-polluted waterway is becoming cleaner.

The creatures are typically found from the Mediterranean Sea and Canary Islands to the English Channel.

Announcement of the discovery was delayed until the species became protected under law, with fines or imprisonment imposed on those found killing, injuring or capturing the seahorses.

Bat Slaughter

The carcasses of dozens of rare grey-headed flying foxes have been found along Australia’s Queensland coast after a slaughter locals describe as “horrific.”

The protected species is Australia’s largest bat and is crucial for pollination in Queensland’s forests.

The killings are the latest in a spate of animal mutilations that have mainly been focused in Victoria state, and include kangaroo, wallaby and koala.

Those who found the bat carcasses said they tried to help the baby bats whose mothers had been killed, but were able to save only two.

Environment

Global Temperature Extremes

The week’s hottest temperature was 113 degrees Fahrenheit (45.0 degrees Celsius) in Catamarca, Argentina.

The week’s coldest temperature was minus 55.0 degrees Fahrenheit (minus 48.3 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 8 November – 14 November 2017

Agung | Bali (Indonesia) : PVMBG reported that white plumes from Agung rose as high as 500 m above the crater rim during 8-14 November. The Alert Level remained at 3 (on a scale of 1-4), and the exclusion zones remained intact (at 6 km, and an additional expansion to 7.5 km in the NNE, SE, S, and SW directions).

Aira | Kyushu (Japan) : JMA reported that an explosion at Minamidake summit crater (at Aira Caldera’s Sakurajima volcano) detected at 1025 on 7 November generated an ash plume that rose 1.3 km above the crater rim. A very small event occurred at the same crater on 13 November. The Alert Level remained at 3 (on a 5-level scale).

Cleveland | Chuginadak Island (USA) : AVO reported that during 8-13 November elevated surface temperatures in Cleveland’s summit crater were identified in satellite data, possibly indicative of a lava flow in the crater. No significant eruptive activity was detected by seismic or infrasound sensors; both sensors detected a signal associated with low-level emissions during 0056-0059 on 12 November. A small explosion was recorded at 0315 on 14 November. The Aviation colour Code remained at Orange and the Volcano Alert Level remained at Watch.

Dukono | Halmahera (Indonesia) : Based on analyses of satellite imagery, wind model data, and notices from PVMBG, the Darwin VAAC reported that during 8-14 November ash plumes from Dukono rose to an altitude of 2.1 km (7,000 ft) a.s.l. and drifted in multiple directions.

Ebeko | Paramushir Island (Russia) : Based on observations by volcanologists in Severo-Kurilsk (Paramushir Island), about 7 km E of Ebeko, explosions during 5 and 7-8 November generated ash plumes that rose as high as 2 km (6,600 ft) a.s.l. The Aviation colour Code remained at Orange (the second highest level on a four-colour scale).

Katmai | United States : On 13 November AVO reported that a cloud of ash, resuspended by strong winds in the vicinity of Katmai and the Valley of Ten Thousand Smokes, was blown about 120 km SE over Shelikof Strait and Kodiak Island at an altitude of up to 3 km (10,000 ft) a.s.l. The ash was originally deposited during the Novarupta eruption in 1912. The Volcano Alert Level remained at Normal and the Aviation colour Code remained at Green.

Kilauea | Hawaiian Islands (USA) : During 8-14 November 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, ceased entering the ocean at Kamokuna on 8 November but then began reentering the ocean during 12-13 November. Surface lava flows were active above and on the pali, and on the coastal plain, and new breakouts were observed.

Sabancaya | Peru : Observatorio Vulcanológico del Sur del IGP (OVS-IGP) and Observatorio Vulcanológico del INGEMMET (OVI) reported that explosive activity at Sabancaya increased compared to the previous week; there was an average of 66 explosions recorded per day during 6-12 November. Seismicity was dominated by long-period events, with signals indicating emissions. Gas-and-ash plumes rose 4 km above the crater rim and drifted 50 km NE, E, and SE. The MIROVA system detected six thermal anomalies. The sulfur dioxide flux was high, at 2,763 tons per day on 8 November. The report noted that the public should not to approach the crater within a 12-km radius.

San Cristobal | Nicaragua : INETER reported that a series of 14 explosions at San Cristóbal began at 2134 on 7 November. The first explosion was the strongest, causing an increase in RSAM to 150 units; RSAM dropped to 50 after the last explosion. Ash fell in areas to the W and NE, including in the communities of Los Farallones, San Agustín, La Mora, El Naranjo, and Chinandega.

Sheveluch | Central Kamchatka (Russia) : KVERT reported that a thermal anomaly over Sheveluch was identified in satellite images on 3, 6, and 8 November; weather clouds prevented observations on the other days during 4-10 November. Explosions on 8 November generated ash plumes that rose 8 km (26,200 ft) a.s.l. and drifted 990 km NE. The Aviation colour Code remained at Orange.

Sinabung | Indonesia : Based on observations by PVMBG, satellite and webcam images, and model data, the Darwin VAAC reported that during 9 and 11-12 November ash plumes from Sinabung rose 4.6-4.9 km (15,000-16,000 ft) a.s.l. and drifted E and ESE. The Alert Level remained at 4 (on a scale of 1-4).

Suwanosejima | Ryukyu Islands (Japan) : Based on JMA notices and satellite data, the Tokyo VAAC reported that on 10 November an event at Suwanosejima produced a plume that rose 1.8 km (6,000 ft) a.s.l. and drifted NW.

Turrialba | Costa Rica : OVSICORI-UNA reported that an ash emission at Turrialba began before 0730 on 13 November and intensified around 0830. An ash plume rose 500 m above the crater rim and drifted SW.
