Significant earthquakes strike near Bardarbunga volcano

At least 8 more earthquake measuring 4.0Mw or greater have occurred near Bardarbunga volcano in Iceland since Friday.

4 of the quakes measured 5.0Mw or greater, including three  shocks that registered 5.2Mw, according to the data provided by the Icelandic Met Office (IMO).

Meantime, IMO has issued the following warnings

  • Warning: Fissure eruption continues in Holuhraun lava field, north of Vatnajökull (Vatna Glacier).
  • Warning: Today (Sunday) volcanic gas emissions are expected to drift east and later to the northeast of the eruption site. Tomorrow (Monday) the pollution will affect areas to the north and northwest.

3 Earthquakes measuring magnitude 5.0 or greater strike near Bardarbunga volcano

At least 22 earthquakes measuring magnitude 3.0 or greater, including 3 measuring magnitudes 5.0, 5.1 and 5.3 have occurred near Bardarbunga volcano since Saturday, reported IMO.

Volcanic activity in Holuhraun Lava Field

Meantime, the fissure eruption continues “at a stable level,” said IMO. “No explosive activity is observed, the eruption remains an effusive lava eruption. Visual observation by webcam and low level volcanic tremor on seismometers do not show any obvious changes since [Sunday] evening.”

M5.1 quake occurs at northern rim of  Bardarbunga caldera: IMO

Centered at 64.675°N, 17.415°W, about 6.6km NE of Bardarbunga, the quake occurred at a depth of 5.2 km [USGS/EHP: 64.723°N 17.390°W depth=7.5km] on Sunday at 12:01:45GMT, said Iceland Met Office (IMO).

The quake was the largest to strike Bardarbunga volcanic system since a magnitude 5.4 shock on Saturday.

Meantime, a large fissure eruption continues in Holuhraun lava field, north of Vatnajokull [Glacier of Lakes.]

“A lava eruption started in Holuhraun shortly after 04 AM, on the same volcanic fissure, which erupted earlier this week. The fissure is estimated to be 1.5 km long.”

The lava extruding from the fissure was estimated at 1 km wide, 3 km long and several meters deep, oozing down in a northeasterly direction. The flow rate was about 1,000 m3 per second, said IMO.

The Aviation Color Code for Bárðarbunga has been downgraded from “red” to “orange” [because no ash has been detected] and the alert level for Askja to “yellow,” said IMO.

New fissure eruption near Bardarbunga prompts ‘Red Alert’

Iceland has once again raised its aviation warning to the highest level after a new fissure eruption in Holuhraun lava field near Bardarbunga volcano.

Volcanologists monitoring restive Bardarbunga observed a fissure eruption at 05:15GMT on Sunday, said IMO.

“It appears that the eruptive fissure is longer than in the last eruption. It is extending north and south on the same . The eruption is a very calm lava eruption and can hardly be seen on seismometers. Visual observation confirm it is calm, but continuous.”

Currently, only lava is erupting, but no ash has been observed, added IMO.

The eruption prompted IMO to raise the aviation warning code to ‘red’ for the large area that houses the Bardarbunga volcanic system.

The new fissure is located very close to the Friday’s, with the fracture extending further to the north, said a researcher.

The latest eruption is said to be far more more intense than Friday’s, with the lava flow estimated to be more than 10 times greater.

Meantime, seismicity continues on a 15-km-long region of the dyke intrusion, said IMO, “extending both into the Dyngjujökull glacier and the region north of the ice margin. Earthquakes have not migrated northwards during the last two days.”

An estimated 500 million cubic meters of lava has flowed from beneath the volcano in a long dyke since last week.

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.
