Magnitude 5+ Earthquakes – Global

There are no magnitude 5+ earthquakes reported today so far.

Sinking Islands

An Australian study says that sinking caused by seismic activity around some Pacific islands may pose a greater threat to their survival than rising sea levels.

Researchers from the University of Newcastle found that sea levels around American Samoa rose at five times the global average due to the sinking effect brought on by 2009 Samoa-Tonga earthquakes.

They found the predicted subsidence is as much, if not more, than the official U.N. climate panel’s projected sea rise from man-made climate change. Other countries, such as Japan and New Zealand, may see their land areas rise, mitigating rising sea levels in those locations.

Libya – A wave of heavy rainfall and thunderstorm has hit the south western region of Libya. The rainfall commenced on the 28 May 2019 and intensified on the 2 June. The municipality of Ghat has been severely affected, including: Silila, Ta’ala, Ghat, Albakat, Saya, Alfiywat, Al-Sharika and Al-Siniyah. The water levels have not receded and vary between 0.5 to 2 meters depending on the area. Over 20,000 people have been affected by the floods and an estimated 2,500 have been displaced to nearby areas. Most of the displaced families are hosted with relatives or sheltered in three schools habilitated by the municipality. Human casualties have been reported. To date, four died (including three children and one adult) and 30 people suffered minor injuries.

USA – Before and After Images

Record-shattering rainfall swamped the south-central U.S. over the past few weeks, leading to catastrophic flooding along the Arkansas River in both Oklahoma and Arkansas. In several locations, the river was at its highest level ever recorded, including Fort Smith, Ark. Elsewhere, eight states along the Mississippi River endured the longest period of flooding since the Great Flood of 1927. Images captured Feb. 25 and June 1 at Fort Smith and Moffett.

Early Migration

East Africa’s annual wildebeest migration began nearly a month early due to unusual weather patterns this season. The premature start in late May caught many safari resorts and tour operators off guard.

“Climate changes such as heavy rains in Tanzania as well as depletion of resources in one area are among the reasons we are having an early wildebeest migration,” said Shadrack Ngene of the Kenya Wildlife Service.

Kenyan weather experts say the rainy seasons have become unreliable and do not follow the schedules of just a few decades ago.

Everest clean-up

Nepali climbers have retrieved four bodies and collected some 11 tonnes of decades-old garbage from Mount Everest and its approach below the base camp as part of a drive to clean up the world’s highest mountain.

Climbers returning from the 8,850-metre mountain say its slopes are littered with human excrement, used oxygen bottles, torn tents, ropes, broken ladders, cans and plastic wrappers left behind by climbers, an embarrassment for a country that earns valuable revenue from Everest expeditions.

The garbage, along with the bodies of some of the 300 people who have died over the years on Everest’s slopes, are buried under the snow during winter, but become visible when the snow melts in summer.

Plastic Pollution

Humans on Earth eat at least 50,000 particles of microplastic on average each year and inhale a comparable amount as well, according to new research that looked at data from 26 previous studies. Some experts estimate the level being absorbed by people is actually much higher.

The plastic pollution is entering the human food chain and environment due to the disintegration of plastic bags, bottles and other litter, which has now reached virtually every corner of the planet.

Another study cautions that pathogens and other organisms have been found to grow on microplastics in fresh water, posing a potential threat to the health of humans and wildlife.

Global Volcanic Activity – Ongoing Activity for the week of 29 May – 4 June 2019

Agung | Bali (Indonesia) : PVMBG reported that at 1142 on 31 May an explosion at Agung produced a dense gray ash plume that rose 2 km and drifted NE and E. Roaring was audible from the Agung Volcano Observatory in Rendang (about 8 km SW). The Alert Level remained at 3 (on a scale of 1-4) with the exclusion zone set at a 4-km radius.

Aira | Kyushu (Japan) : JMA reported that during 27 May-3 June very small eruptive events at Minamidake crater (at Aira Caldera’s Sakurajima volcano) were recorded as well as periodic crater incandescence. The Alert Level remained at 3 (on a 5-level scale).

Asosan | Kyushu (Japan) : JMA reported that very small eruptive events at Asosan’s Nakadake Crater on 29 and 31 May generated plumes that rose 400 m above the crater rim and, according to the Tokyo VAAC, drifted S and N, respectively. Sulfur dioxide emissions continued to be high at 2,000 tons per day. The Alert Level remained at 2 (on a scale of 1-5).

Dukono | Halmahera (Indonesia) : Based on satellite and wind model data, and notices from PVMBG, the Darwin VAAC reported that during 29 May-4 June ash plumes from Dukono rose to altitudes of 2.1-2.4 km (7,000-8,000 ft) a.s.l. and drifted NW and W. The Alert Level remained at 2 (on a scale of 1-4), and the public was warned to remain outside of the 2-km exclusion zone.

Ebeko | Paramushir Island (Russia) : Volcanologists in Severo-Kurilsk (Paramushir Island), about 7 km E of Ebeko, observed explosions during 25-28 May that sent ash plumes up to 3 km (10,000 ft) a.s.l. A thermal anomaly over the volcano was identified during 27-28 May. The Aviation colour Code remained at Orange (the second highest level on a four-colour scale).

Ibu | Halmahera (Indonesia) : The Darwin VAAC reported that on 31 May multiple ash plumes from Ibu rose to an altitude of 2.1 km (7,000 ft) a.s.l. and drifted W based on satellite data. On 2 June ash plumes rose to an altitude of 3 (10,000 ft) a.s.l. and drifted W. The Alert Level remained at 2 (on a scale of 1-4), and the public was warned to stay at least 2 km away from the active crater, and 3.5 km away on the N side.

Karymsky | Eastern Kamchatka (Russia) : KVERT reported that an ash plume from Karymsky was identified in satellite images drifting 45 km NE on 24 May and a thermal anomaly was visible during 28-29 May. The Aviation colour Code remained at Orange (the second highest level on a four-colour scale).

Klyuchevskoy | Central Kamchatka (Russia) : KVERT reported that ash plumes from Klyuchevskoy were last observed on 22 April and a weak thermal anomaly was last identified on 15 May. KVERT lowered the Aviation colour Code to Yellow (the second lowest level on a four-colour scale) on 31 May.

Krakatau | Indonesia : PVMBG reported that Anak Krakatau’s seismic network detected two eruptive events on 29 May and two events on 2 June. None of the events were followed by visible ash emissions, though observations were hindered by weather conditions. The Alert Level remained at 2 (on a scale of 1-4), and the public was warned to remain outside of the 2-km radius hazard zone from the crater.

Merapi | Central Java (Indonesia) : PVMBG reported that during 24-30 May the lava-dome volume at Merapi did not change and was an estimated 458,000 cubic meters, based on analyses of drone footage. Extruded lava fell into the upper parts of the SE flank, generating one block-and-ash flow that traveled 1.1 km down the Gendol drainage. White plumes rose as high as 400 m above the summit. A news article stated that block-and-ash flows descended the Gendol drainage during 1-2 June, traveling as far as 1.2 km. In addition, incandescent dome material traveled 750 m on 2 June. The Alert Level remained at 2 (on a scale of 1-4), and residents were warned to remain outside of the 3-km exclusion zone.

Poas | Costa Rica : OVSICORI-UNA reported that multiple phreatic eruptions at Poás recorded during 29 May-1 June produced plumes that rose as high as 500 m above the vent.

Santa Maria | Guatemala : INSIVUMEH and CONRED reported that during 29-30 May lahars descended Santa María’s San Isidro drainage (tributary of El Tambor), carrying blocks 1-3 m in diameter and tree trunks. The lahars were 20 m wide and 1.5 m deep; CONRED noted that the 29 May lahar was hot and had a sulfur odor. Explosions recorded during 30 May-4 June generated ash plumes that rose as high as 800 m above the crater and drifted E and SE. Avalanches of material descended the E and SE flanks.

Sheveluch | Central Kamchatka (Russia) : KVERT reported that a thermal anomaly over Sheveluch’s lava dome was identified daily in satellite images during 24-31 May. The Aviation colour Code remained at Orange (the second highest level on a four-colour scale).

Suwanosejima | Ryukyu Islands (Japan) : JMA reported that crater incandescence at Suwanosejima’s Ontake Crater was occasionally visible at night during 24-31 May. An eruption at 1629 on 30 May generated a plume that rose 1.1 km above the crater rim. The Alert Level remained at 2 (on a 5-level scale).
