Earthquakes

Magnitude 5+ Earthquakes – Global

8.1 Earthquake hits offshore Chiapas, Mexico.

The magnitude 8.1 earthquake that hit the country is the biggest the country has seen in a century. Authorities in Mexico say that a hotel in Oaxaca has collapsed, while 12 people have reportedly died. Tsunami waves were possible, but no reports of unusual waves were received. Buildings as far away as Mexico City swayed in the tremor which caused residents to rush out into the streets. More than a million people were left without power. 62 aftershocks have hit the country so far.

Solar Strandings

A string of powerful solar storms interacting with Earth’s geomagnetic field may have been the cause of 29 beachings of sperm whales around the North Sea last year, scientists say.

Researchers from Germany’s University of Kiel found that the solar storms distorted the planet’s magnetic field by hundreds of miles, interfering with the whales’ sense of orientation.

Klaus Heinrich Vanselow and colleagues conclude that the whales would have been confused by the magnetic shifts because they grew up in the eastern Atlantic where such solar disruptions are typically much weaker.

Wildlife Conflicts

Animal rights groups expressed outrage at the Romanian government’s move to kill or relocate 140 bears and 97 wolves following a number of attacks on humans.

The World Wildlife Fund (WWF) strongly denounced the measure and blamed the attacks on deforestation. “The authorities should first address the problems that have prompted bears to get closer and closer to human settlements in the search for food,” Cristian Papp, the head of WWF’s Romanian branch, told Agence France-Presse.

About 6,000 brown bears roam in and around the country’s Carpathian Mountains.

Huge Jelly Blobs Spotted Off Norway Coast

Giant, jelly-like blobs have been sighted off the western coast of Norway, but the identities of these mysterious objects have scientists stumped.

The blobs are about 3.3 feet (1 meter) in diameter and are translucent, except for a strange dark streak running through their center, Science Nordic reported. No one knows what they are, or what made them.

The Norwegian blobs could be squid egg masses, but their appearance is different from any squid egg sac that has been identified before now. Researchers suggest the mystery could be solved by doing an DNA test on the jelly and compare the results to known DNA codes.

Brazil announces end of yellow fever outbreak

The Brazilian Ministry of Health announced Wednesday the end of the yellow fever outbreak. The last case was registered in June. The outbreak that started in Dec 2016 accounted for 777 confirmed cases and 261 deaths. The southeastern region was the hardest hit seeing the vast majority of cases. Nearly 37 million yellow fever vaccine doses were dispensed.

Cholera Outbreak in the Philippines

More than 100 people have been sickened by cholera in a barangay, or village near the beaches in the municipality of Oas in Albay province, according to an Abante report. One individual has died. The outbreak began Saturday when residents of the area started reported symptoms of vomiting and diarrhea.

Middle East respiratory syndrome coronavirus (MERS-CoV) – Saudi Arabia

Between 13 and 30 August 2017, the National IHR Focal Point of Saudi Arabia reported 12 additional cases of Middle East respiratory syndrome coronavirus (MERS-CoV), including one death and, and one death from a previously reported case.

Foot and Mouth Disease – Zimbabwe

The government of Botswana announced on Thursday that it has donated a vaccine for Foot and Mouth Disease (FMD) to neighbouring Zimbabwe in order to assist the country to tackle the current disease outbreak. Botswana, once an avid exporter of beef to the European Union (EU) faced serious challenges with several outbreaks of FMD over the last couple of years, greatly jeopardizing the growth of the country’s beef sector. Most of the previous FMD outbreaks in Botswana started in the northern and northwestern regions of the country, where it shares a border with Zimbabwe.

Roundup of Global Volcanic Activity – Ongoing Activity for the week of 30 August – 5 September 2017

Aira | Kyushu (Japan) : JMA reported that six explosive events at Showa Crater (at Aira Caldera’s Sakurajima volcano) during 28 August-4 September ejected material as far as 800 m. Ash plumes rose as high as 2.2 km above the crater rim. Crater incandescence was observed at night. The Alert Level remained at 3 (on a 5-level scale).

Bagana | Bougainville (Papua New Guinea) : Based on analyses of satellite imagery and model data, the Darwin VAAC reported that on 31 August ash plumes from Bagana rose to an altitude of 2.1 km (7,000 ft) a.s.l. and drifted N, W, and SW.

Bezymianny | Central Kamchatka (Russia) : KVERT reported that during 28-30 August a thermal anomaly over Bezymianny was identified in satellite images. A lava flow continued to flow down the W flank of the dome; incandescence from the dome was visible at night. The Aviation colour Code remained at Orange (the second highest level on a four-colour scale).

Bogoslof | Fox Islands (USA) : AVO reported that an explosive event at Bogoslof began at 0405 on 30 August and continued intermittently until 0555; the event produced a low-level ash plume that rose to around 6.1 km (20,000 ft) a.s.l. and drifted SSE. Later that day seismic and infrasound data showed quiet conditions, and a low-level plume (likely steam) drifted almost 65 km SSE. Satellite, infrasound, and seismic data showed nothing notable during 31 August-5 September. The Aviation colour Code remained at Orange and the Volcano Alert Level remained at Watch.

Cleveland | Chuginadak Island (USA) : AVO reported that elevated surface temperatures at Cleveland were identified in satellite data during 29-30 August and 4-5 September; cloudy weather sometimes prevented satellite and webcam observations. Small vapor plumes from the summit was observed in webcam images during 30-31 August. Nothing noteworthy was detected in seismic or infrasound data. 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 30 August-1 September and 3-5 September ash plumes from Dukono rose to altitudes of 1.5-2.4 km (5,000-8,000 ft) a.s.l. and drifted SW, W, and NW.

Ebeko | Paramushir Island (Russia) : Based on observations by volcanologists in Severo-Kurilsk (Paramushir Island), about 7 km E of Ebeko, explosions during 28-29 August generated ash plumes that rose as high as 2.2 km (7,200 ft) a.s.l. Minor amounts of ash fell in Severo-Kurilsk on 28 April. The Aviation colour Code remained at Orange (the second highest level on a four-colour scale).

Karymsky | Eastern Kamchatka (Russia) : KVERT noted gas-and-steam emissions at Karymsky since 12 August. The Aviation colour Code was lowered to Yellow (the second lowest level on a four-colour scale) on 30 August.

Kilauea | Hawaiian Islands (USA) : During 30 August-5 September 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. The 61G lava flow, originating from a vent on Pu’u ‘O’o Crater’s E flank, continued to enter the ocean at Kamokuna. Surface lava flows were active above the pali and on the coastal plain. Slumping of seaward portions of the delta continued, and cracks running parallel to the coastline continued to widen. HVO warned of the potential for larger-scale delta collapses.

Klyuchevskoy | Central Kamchatka (Russia) : Based on satellite data, KVERT reported that ash plumes from explosions at Klyuchevskoy rose 6 km (19,700 ft) a.s.l. and drifted 550 km in multiple directions during 24-25 and 30 August. On 6 September KVERT noted that activity had decreased and that there was snow on the flanks; ash emissions were last observed on 30 August. The Aviation colour Code was lowered to Yellow (the second lowest level on a four-colour scale).

Langila | New Britain (Papua New Guinea) : Based on analyses of satellite imagery and model data, the Darwin VAAC reported that during 1-2 September ash plumes from Langila rose 1.8 km (6,000 ft) a.s.l. and drifted N and NW.

Manam | Papua New Guinea : Based on analyses of satellite imagery and model data, the Darwin VAAC reported that on 2 September an ash plume from Manam rose 2.1 km (7,000 ft) a.s.l. and drifted NNW.

Nishinoshima | Japan : The Japan Coast Guard reported that visual observations of Nishinoshima from an aircraft during the afternoon of 11 August suggested that the eruption was continuing; a high temperature area at the ocean entry on the W flank and a steam plume indicated flowing lava. Lava in the central crater could not be confirmed; a small fumarolic emission rose from the crater’s edge. Observations on the afternoon of 24 August suggested no lava flowing into the ocean.

Sabancaya | Peru : Observatorio Vulcanológico del Sur del IGP (OVS-IGP) and Observatorio Vulcanológico del INGEMMET (OVI) reported that explosive activity at Sabancaya was similar to the previous week; there was an average of 44 explosions recorded per day during 28 August-3 September. The earthquakes were dominated by long-period signals, with fewer numbers of hybrid events and signals indicating emissions. Gas-and-ash plumes rose 3.2 km above the crater rim and drifted no more than 40 km SE and S. The MIROVA system detected five thermal anomalies. The report warned the public not to approach the crater within a 12-km radius.

Sheveluch | Central Kamchatka (Russia) : KVERT reported that a thermal anomaly over Sheveluch was identified daily in satellite images during 25 August-1 September. The Aviation colour Code remained at Orange.
