Earth is fighting to stay alive. Mass dieoffs, triggered by anthropogenic assault and fallout of planetary defense systems offsetting the impact, could begin anytime!

1 Million Ukrainians Displaced by Conflict

More than 1 million people have been displaced since the conflict began in Ukraine, says the United Nations refugee agency (UNHCR).

“It’s safe to say you have over a million people now displaced as a result of the conflict, internally and externally together,” Reuters quoted director of the UNHCR’s bureau for Europe, as saying.

“I mean 260,000 [internally displaced] in Ukraine—it’s a low estimate—and 814,000 [have fled to] Russia.”

There has been a surge in the number of war refugees internally displaced in Ukraine since about mid August, local media reported.

Bardarbunga Eruption

Volcanic activity continues in Holuhraun lava filed webcam images show, The rate of flow remains steady with no visible change in activity since Monday, with effusive lava eruption and fountains, said IMO.

The largest earthquake to hit the volcano system measured 3.1Mw, which occurred in the northern part of the magma field with additional seismicity detected beneath the glacier rim.

IMO said:

  • The eruption has not created any ash-fall. A white plume of steam and gas rises from the eruption on Holuhraun, reaching an elevation of about 4.5 km above sea level. Downwind, a volcanic cloud extends from the eruption site. Yesterday afternoon a white cloud from the eruption extended 60 km to the north-north-east.
  • In comparison to yesterday, more [sulfur] dioxide has been measured in the eruption cloud.
  • Sandstorms on the floodplain around the eruption site have contributed fine-grained particles to the eruption cloud. This was seen as a light-brown haze earlier today near to Egilsstaðir.
  • The eruptive fissure is about 1.5 km in length, positioned about 4.5 km from the ice margin of Dyngjujökull.
  • At 14:00 UTC yesterday, the lava flow was 4.2 km2 in area. At 08:00 UTC the edge had extended 1.5 km to the east-south-east.

 Tungurahua shows  increased activity: Ecuador Seismologists

Dozens of explosions were recorded at the volcano on Monday, as experts warned of renewed sudden increases in explosive activity.

The volcano has been ejecting plumes of ash to heights of about to 3km since Wednesday.

The 5,023-m volcano has been active since 1999, and has shown signs of increased activity since February 1, 2014.

Throat of Fire,” as it’s known in the in the local Quechua language, is one of nine or so active volcanoes in Ecuador, located about 140 km  south of the capital, Quito.

 Flash Floods in Sweden and Denmark

Extreme Rain Events triggered flash floods causing traffic chaos in Sweden and Denmark, submerging occupied vehicles, and forcing the evacuation of residents in some areas, AP reported.

Some 120mm (4.7 inches) of rain fell in about three hours, inundating the Danish capital, Copenhagen.

Many Dead or Missing after Severe Flooding in SW China

Extreme Rain Events triggered widespread flash floods and landslides in southwest China’s Chongqing Municipality, leaving dozens dead or missing, said a report.

Fissure eruption reported in Holuhraun lava field, Dyngjujokull glacier, Iceland

The eruption breached surface in Holuhraun lava field about 5km north of Dyngjujokull about 00:02 GMT on Friday, said IMO.

Seismic activity has decreased as a result of the pressure release, however a significant amount of earthquakes is still detected in the magma dike, between the eruption site and south to about 5 km into Dyngjujökull.

The aviation color-code was raised to “red” and back to “orange,” as there was no ash emission.

A significant shock measuring 5.2Mw centered at 64.770°N, 17.335°W occurred at a depth of 7.5km at 12:21UTC, said USGS/EHP.

Tavurvur Volcano Erupts in Papua New Guinea (PNG)

Mount Tavurvur on PNG’s East New Britain Island erupted violently at 3.00 a.m. local time,  said Rabaul Volcanological Observatory.

It ejected plumes of smoke and ash to a height of about 17,000m over the South Pacific island country, forcing the authorities to warn local residents to stay indoors, and causing airlines to alter some flight paths.

“Flight paths between Sydney and Narita (Tokyo) and Sydney and Shanghai have been altered as a result of the volcanic ash cloud over Rabaul in eastern Papua New Guinea,” Qantas spokeswoman told Reuters.

The eruption reached the top of the atmosphere at 50,000 feet, which is the same height as which planes travel, could disrupt air flights from Australia, said the Volcanic Ash Advisory Center in Darwin, Australia.

M5.6 Quake Strikes South of Athens, Greece

Centered at 36.738°N, 23.757°E, about 137km south of Athens, the quake struck at a depth of 91.8km, said USGS/EHP.

The quake was felt in Athens; however, there were no reports of casualties or severe damage, as of posting.

Tavurvur Ejects Clouds of Ash in PNG

Rabaul Volcano’s Tavurvur Cone Spews Ash

On June 25, 2009 Fire Earth Moderators  said:

FEWW expects ongoing activity, punctuated by explosive eruptions by the volcano, for the rest of 2009 and possibly most of 2010.


Since a major eruption in 1994 that forced the complete evacuation of the nearby city of Rabaul [it covered parts of the city in more than a foot of ash,] Rabaul Volcano on the island of New Britain has remained intermittently active. Rabaul is a large caldera volcano whose eastern rim has been breached and flooded by the sea. Numerous vents and cones occur around the rim, including Tavurvur Cone, which was erupting when this image was captured by the Advanced Land Imager on NASA’s Earth Observing-1 (EO-1) satellite on November 30, 2009.

From November 20–26, strong eruptions from Tavurvur shot ash plumes 1.5 km  into the air and “showered the flanks with lava fragments that were incandescent at night.” said a report.  Rabaul Caldera was formed after an eruption that occurred  about 2,500 (± 1,000) years ago.
