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

Significant earthquakes strike Ethiopia, New Zealand

More than two dozen Earthquakes strike Eritrea, Ethiopia

The swarm included two significant shocks measuring 5.7Mw and striking at depths of about 8 km.

The earthquake swarm occurred within the Afar Triangle where the Arabian Plate, and the two parts of the African Plate (the Nubian and the Somalian) diverge. The swarm’s center was located about 100km ESE of Erta Ale volcano, and about 160km NE of the Dabbahu Fissure.

FIRE-EARTH believes there’s a strong probability that the quakes may have primed one or more regional volcanoes for eruption.

At 120 meter below sea level, Ethiopia’s Afar Depression is one of the lowest and hottest places on Earth, famous for its salt mines.

New Zealand Earthquakes

Since earlier this morning local time a swarm of at least a dozen earthquakes have struck Christchurch, New Zealand. The largest shocks measured 5.2 and 6.0Mw, USGS/EHP reported.

At least 10 people were injured and several buildings have collapsed/were damaged as a result of the earthquakes, reports said.

Volcanic Explosions Could Split More Than Africa

Posted by feww on November 4, 2009

Volcanic Explosions and Large Earthquakes Could Splinter Several Continents, Countries

Large earthquakes and volcanic explosions could split Arabian Plate, North American Plate, Pacific Plate [in multiple places] and shatter Filipino Plate.

Erta Ale is part of the so-called Afar Triangle, a highly active volcanic region which includes Dabbahu Volcano, located in the remote Afar Region of Ethiopia. Dabbahu eruption in 2005 created a large fissure in the ground, called the Dabbahu fissure. The volcano is the hottest place on Earth’s  surface.

Leading to Dabbahu’s only known eruption in recorded history, which formed a 500 meter long fissure and a 30 meter wide pumice cone at the fissure’s southern end, on September 26, 2005 the ground swelled as a cluster of more than 130 tremors shook the area near the volcano.

Researchers say volcanic activity could split the African continent in two, a claim supported by a recent ground rupture that appeared in northeastern Ethiopia.

The 60-kilometre (35-mile) split in the desolate Afar region, which was the result of two volcanic eruptions in September 2005 [Dabbahu Episode, Afar,]  has enabled scientists to further examine the earth’s tectonic movements, said a report published in the Geophysical Research Letters.

“The significance of the finding is that a huge magnetic deformation can happen within a few days like in oceans,” Atalay Arefe, an Ethiopia-based university professor who was part of the study, told AFP in an interview.

Faults and fissures that normally occur on the ocean floor largely contribute to the continents breaking off  and moving away [spreading] from each other, in the same way African continent broke away from South American plate 100 million years ago.

“Normally, such phenomena happens beneath the ocean, which is inaccessible, expensive and very difficult to make experiments. But in Afar, it’s quite a natural laboratory for us to carry those out,” Atalay said.

Atalay, who was part of an international group of scientists who have been undertaking studies since the eruptions, said the event indicated what was likely to happen in the mainland.

“The ocean’s formation is happening slowly, likely to take a few million years. It will stretch from the Afar depression (straddling Ethiopia, Eritrea and Djibouti) down to Mozambique,” he said.

At 120 meter below sea level, Ethiopia’s Afar Depression is one of the lowest and hottest places on Earth, famous for its salt mines.
