Thera are in Bali  about 1000 Swedish tourists  waiting the flight back to Swedn. Flights are cancelled  yet.

Where is Bali is there r alternative ways to travel  back  home from Bali?frpm, Bali to  Australia 1300 km. Thera are boats. 1300 is as long a journey  as from Helsinki to the uttermost  Northern point of Finnish lapland.  Lappland.

Agung Volcano, Bali, Indonesia
A summit eruption occurred at Agung volcano, Bali, Indonesia, 21st November 2017. Small ash cloud rising 700 m above summit and drifting east. Five villages affected by the ash, including Pidpid, Nawakerti, Bukit Galah, Sebudi and Abang.

Ambae Volcano, Vanuatu
A summit eruption has been reported at Ambae volcano, Vanuatu. A new cinder cone formed in the summit lake, and a lava pond is visible. This is the first time a lava pond has been observed at Ambae volcano.

Agung Volcano, Bali, Indonesia
On 22nd September 2017, Agung volcano, Bali was raised to maximum level 4 alert. 35,000 people were evacuated. Previous reported eruptions of Agung were in 1963, 1843, 1821?, 1808. The last eruption in 1963 was similar in magnitude/intensity to Mt St Helens (1980) and Mt Vesuvius (79 AD).

Ambae Volcano, Vanuatu
Activity increased at Ambae volcano, Vanuatu on 23 September 2017. Ash emissions occurred from the summit. The alert level was raised to 4 (out of a maximum 5). Preparations were being made to evacuate up to 5000 people.

Agung Volcano, Bali, Indonesia
On 18th September 2017, Agung volcano, Bali was raised to level 3 alert (out of a maximum 4). People are advised not to climb or camp inside Agung crater, and in areas within a 6 km radius of Agung, or at elevations above 950 m from sea level. The exclusion zone radius is increased to 7.5 km in the North, Southeast and South-Southwest. An increase in earthquakes at the volcano is caused by magma pressure cracking rocks. The history of activity at Agung indicates the potential threats of pyroclastic falls, pyroclastic flows, and lava flows. Agung volcano last erupted in 1963. The eruptions of Agung volcano in 1963 created a crimson sunset glow over America and Europe.

About Submarine´s fate

http://edition.cnn.com/2017/11/23/americas/argentina-submarine/index.html

An explosion incidence  can  be    possible according  registered  data.  Searching of  the submarine is going on under  difficult circumstances, stormy weather,  waves can be 8 meter high. The  sea bottom  along Argentine coast line has also very peculiar  complex geomorphology   with  a   steeps towards abyssus , where no  rescue is possible.  Searching  is made in   frames of possibilities and probabilities.   Enormous international  searching operation  is going.

Abstract

In the framework of the Vulnerable Marine Ecosystems (VME) of the High Seas of the South West Atlantic, large areas of the Argentine Continental Margin (ACM) between 44°30’S and 48°S have been swath-mapped for the first time, obtaining full data coverage of the seafloor in this region between the outermost continental shelf and the middle slope down to 1600 m water depth.

The slope is characterized by the presence of smooth terraces (Nagera, Perito Moreno and Piedra Buena) that widen towards the south, limited by morphological steps with evident signs of erosion in the form of scours. These terraces form part of the Argentine contourite depositional systems, generated by the interaction of the northwards flowing Antarctic water masses with the seafloor. Within the studied area, seven canyons and their multiple branches dissect the upper and middle continental slopes, from west to east, across the terraces and the steps.

 

These canyons, which belong to the Patagonia submarine canyon system and are collected at a depth of ~ 3.5 km by a slope-parallel, SSW–NNE-oriented channel known as the Almirante Brown transverse canyon, display a large variety of morphologies. These include incisions from just a dozen of metres to 650 m, straight to highly meandering sections with sharp bends, well-developed levees and walls that reach 35° in slope gradient, hanging branches, conspicuous axial incisions and multiple knickpoints. Only the northernmost canyon indents in the continental shelf, whereas the others start at the limit between the upper and middle slopes, and are often fed by small, straight, leveed gullies.

The action of both across-slope processes represented by submarine canyons and along-slope processes represented by terracing and scouring conform the ACM as a peculiar mixed margin, with the presence of both contour and gravity currents at the same place at the same time. We propose that at present, along-slope erosion and transport mainly occurs along the Perito Moreno terrace, whereas across-slope processes are much more dominant in the Nagera terrace. Erosive bedforms such as crescent scours, generated by contour currents, contribute to the progressive bottom-up erosion of the Nagera terrace and act as an initial collector of across-slope transported sediment, that later, due to flow focusing and recurrence, incise and interconnect creating definitive canyons that progress upslope by retrogressive erosion until their head indents the shelf break.

Changes in the balance between across-slope and along-slope transport would imply a disequilibrium in the combination of processes leading to canyon formation, producing canyon abandonment, and partial or total filling. These changes could be produced by a variation in the depth of the main interfaces of Antarctic water masses leading to either an increase or a decrease in the erosion and transport capacity of contour currents, and/or by an enhancement of across-slope transport related to an increase of sediment availability.

Missing submarine

CNN 21.11. 2017

How long could the crew survive?

In a “worst-case scenario,” the missing sub could run out of oxygen in two days, Argentine navy spokesman Enrique Balbi said Monday.

Under normal circumstances, the vessel has sufficient fuel, water, oil and oxygen to operate for 90 days without external help, said Balbi, and the vessel could “snorkel” — or raise a tube to the surface — “to charge batteries and draw fresh air for the crew.”

If the sub is bobbing adrift on the surface and the hatch is open, it will have an available air supply and enough food for about 30 days, he said.

But if it is submerged and cannot raise a snorkel, its oxygen may last only about seven days. When the sub last made contact on Wednesday, five days ago, it was submerged, Balbi said.

“This phase of search and rescue is critical,” he said. “This is why we are deploying all resources with high-tech sensors. We welcome the help we have received to find them.”

PM of Lebanon went to Saudia

http://www.i24news.tv/en/news/international/middle-east/159975-171111-lebanon-demands-riyadh-explain-pm-hariri-s-absence

Lebanon’s president urged Saudi Arabia on Saturday to explain why Saad Hariri had not returned to Beirut since his surprise resignation as prime minister a week ago.

Hariri announced on November 4 in a televised statement from Riyadh that he would be stepping down from the post, sending shock waves through Lebanese politics.

The premier has yet to return to Lebanon and rumors have swirled that he is being held in Saudi Arabia against his will.
