African Earthquakes Shift Into Middle East

Two large earthquakes in Africa create movement in the Indian Ocean and in the Middle East.

Two days ago, I posted a blog about two large earthquakes in Uganda, Africa, and I wrote:

Keep an eye out for more quakes in this region because they may be a signal that large movements are setting up in the Indian Ocean, east of Africa, in the Middle Eastern regions, and north of Africa in the Mediterranean Sea.

Well, it happened two days later on July 5, 2013 – three quakes hit east and north of Africa.

  1. 4.7 – Mid-Indian Ridge
  2. 4.8 – Yemen
  3. 4.5  – Yemen

Now, keep an eye on Greece.

Uncommon Quakes

Even though Uganda’s East African Rift Valley is one of the most active earthquake zones in East Africa, it is not common for Uganda to experience large earthquakes. When I saw two large quakes occurring within hours of one another on July 3, 2013, I figured that this signaled movement yet to come east and north of Africa.

And, it did.

The Indian Ocean is an area that experiences many strong earthquakes, and in 2004, the Sumatra megaquake spawned the devastating tsunami that slammed into Sri Lanka and southern India. When I see movement in Africa, I watch for movement in the Indian Ocean and in the Middle East.

The Middle East

Two earthquakes strike in Yemen two days after the Ugandan quakes.

Frequent and large earthquakes are also unusual in the Middle East, but they are beginning to occur more often these days, and this is something we need to watch carefully.

A Biblical scholar once told me that the End Times were near when a tsunami hits the Middle East. I am not one for apocalyptic predictions, but a Middle East tsunami is a possibility in the near future. Especially as more quakes strike in countries along the Persian Gulf and Arabian Sea, like Yemen.

All we can do is wait and see.

 

 

Two Large Earthquakes Shake Uganda

A 5.7 magnitude quake, followed three hours later by a 5.4 quake, shook the Lake Albert Region of Uganda, July 3, 2013.

The Nile

The Nile River flows into Lake Albert, and this part of Africa is a geologic “split” in the continent. Uganda lies almost completely within the Nile River Basin, and is home to some of the oldest life forms in Africa.

This region is the most seismically active region in Uganda and also one of the most seismically active zones in the East Africa Rift System because it is bounded by steep active faults. Landslides are commonly triggered by these earthquakes, which block roads and impede relief efforts.

Uganda is in one of the most active earthquake areas in Africa.

Crustal Downthrow

Earthquakes in this part of Africa are connected to one of two possible fault planes, and they signal significant crustal shifting. Earthquakes in this particular region are associated with surface faulting that results in a downthrow to the southeast. This typically signals movement occurring both east and north of the African Plate.

Keep an eye out for more quakes in this region because they may be a signal that large movements are setting up in the Indian Ocean, east of Africa, in the Middle Eastern regions, and north of Africa in the Mediterranean Sea.

 

Prehistoric Continents Discovered Off India And Brazil

On March 3, 2013, researchers found evidence of a landmass estimated to have existed between 2,000 and 85 million years ago.  The fragments of an ancient continent are buried beneath the floor of the Indian Ocean.

May 8, 2013, researchers announced that they found traces of a long-lost island/continent located at a high-rising mass of ocean floor about 930 miles offshore of Rio de Janeiro, Brazil.

Surfacing Our Past

The continents that we live upon today are the archeological remnants of ancient continents, and are merely terrestrial artifacts formed from the fragments of the breakup of older supercontinents, long extinct.

Over the past 500 million years, there have been five different sets of continents, called supercontinents. Sometime in the future, there will be a sixth supercontinent very different from what we know today. All prehistoric continents began as one massive landmass, or “supercontinent.”

Supercontinent #1 – Vaalbara

The earliest known supercontinent was Vaalbara. Vaalbara is believed to have formed about 3,600 million years ago (3.1 billion years ago [3.1 GA]). The basic structure of Vaalbara consisted of eastern South African rocks that match the same rocks found today in the northwest section of Western Australia.

Supercontinent #2 – Kenorland

After Vaalbara, the supercontinent Kenorland was formed around 2.7 billion years ago. Kenorland formed what we know as today’s North America, Greenland, Scandinavia, Western Australia, and the Baltic regions.

Supercontinent #3 – Columbia

After Kenorland, the supercontinent Columbia formed around 2.0–1.8 billion years ago and broke apart about 1.5–1.3 billion years ago[i]. Columbia was small, about 12,900 kilometers (8,000 miles) from North to South, and about 4,800 km (3,000 miles) across its broadest stretch. Fossil records show that the east coast of India was attached to Western North America during this time, and Southern Australia was pushed up against Western Canada. Most of South America was positioned where the western edge of modern-day Brazil lined up with Eastern North America, extending to the southern edge of Scandinavia. The Amazon region in South America first appeared on Columbia[ii].

Supercontinent #4 – Rodinia

The dinosaur disappeared after Rodinia.

After Columbia, the supercontinent Rodinia formed about 1.1 billion years ago, and broke up roughly 750 million years ago. This was a supercontinent that contained most of our present day landmasses, but geologic records show these continents were in an upside down world. Our present day continents were formed from the fragments of the breakup of Rodinia. 

Supercontinent #5 – Pangaea

Some 200 million years later, the broken pieces of Rodinia reconnected as Pangaea, and this was after the extinction that killed the dinosaurs.

Most of Rodinia was concentrated in the Southern Hemisphere, but the North and South poles had shifted at this time, pointing into the Sun. Pangaea was wrapped around the equator like a planetary belt. North America formed the core of Pangaea, called Laurentia, which was at the South Pole[iii].

The southeastern United States was wedged between Africa and South America. Australia, India, and Antarctica formed the largest landmass, called Gondwana, north of Laurentia.

Siberia, Russia was located just south of the equator between Gondwana and Laurentia, and Scandinavia, Europe, European Russia, and much of what is today’s Asia were in fragments along the north coast of Gondwana.

Supercontinent #6 – ????
