Secret of The Hidden Underwater Continent

published on July 3, 2020

a phrase that quite accurately

characterizes our time has been floating

around the internet for a long time born

too late to explore the world born too

early to explore the universe

indeed humanity hasn't flown beyond the

limits of near-earth orbit but in terms

of discovering new lands the anonymous

author clearly spoke too soon

as it turns out in 2017 a new continent

was discovered Zealandia and a couple of

years later scientists discovered that

it was directly connected to the most

dangerous volcanoes on planet Earth

what do this hidden continent and the

Ring of Fire have in common back in the

70s we knew that an additional continent

may exist on our planet but in more

detail Zealandia wasn't studied until

2017 most of it about 49 million square

kilometers or 19 million square miles

an area larger than India is hidden

under the ocean only a few areas appear

on the surface in the form of the

islands of New Zealand New Caledonia and

several other small islands in the

region is most of us understand it a

continent cannot be underwater as a

continent is always mostly above sea

level however this is a better

definition of the word mainland as

continent refers primarily to a large

block of the Earth's crust including

both the protruding islands and the

underwater portion in the case of

Zealandia the underwater section

accounts for almost the entire continent

Zealandia could be mistaken for a

fragment of the ocean floor if it

weren't for its chemical composition

it's low magnesium and iron content for

scientists to categorize this section of

the Earth's crust

as a continent in addition the

continental crust around New Zealand is

clearly separated from the rocks of the

Australian and oceanic plates

however Zealandia was

not always under water over 85 million

years ago

it was part of the supercontinent

gondwana when this giant collapsed part

of Zealandia was covered by water and

formed the Tasman Sea other regions of

Zealandia together with Australia formed

one continent which also subsequently

collapsed approximately 60 million years

ago

this means that dinosaurs witnessed the

times when this part of the continent

still wasn't completely underwater the

most interesting thing in this region

occurred between 50 and 35 million years

ago during this time subduction occurred

across the whole planet this is the

collision and layering of a tectonic

plate on top of another during this

process the oceanic crust usually delves

beneath the continental crust resulting

in the formation of volcanoes and

earthquakes

thanks to these processes one of the

most dangerous places on our planet was

formed the Ring of Fire it encompasses

almost the entire coast of the Pacific

Ocean with the exception of Australia

90% of the most dangerous earthquakes on

earth occur inside this ring the most

dangerous volcanoes are also

concentrated in this region of the 540

active volcanoes on earth 328 are

located along the coasts of the Pacific

Ocean

according to geophysicist rupert

sutherland of victoria university of

wellington and Gerald are Dickins of

Rice University in Texas the formation

of these volcanoes led to the emergence

of modern Zealandia and made it an

independent continent when the slabs

began to overlap part of northern

Zealandia rose 3 kilometers or 186

miles while other sections sunk to

almost the same level as a result 95

percent of the continent was at a depth

of one kilometer or 06 miles underwater

it can be assumed that Zealandia was a

pretty picturesque place because it's

sunken territories are dotted with

mountains the largest of these is the

lord howe rise submarine mountain range

its length is about 2,500 kilometers or

15 hundred and 50 miles and its width

reaches 500 kilometers or 310 miles to

see these mountains you need to travel

more than 1500 meters or 5,000 feet

underwater they were formed when

Zealandia separated from Australia

60 million years ago and became a

dividing strip between the two

continents

the second flooded part of Zealandia the

challenger' plateau formed even earlier

during the collapse of Gondwana during

the collapse this 500 kilometer or 310

mile piece of land immediately went

underwater being covered by the Tasman

Sea the rest of Zealandia is covered by

other mountain systems it turns out that

the formation of this hidden continent

and the Ring of Fire were both parts of

the same process if such an active

movement of tectonic plates had not

occurred 50 million years ago perhaps

the earth would be a safer place the

number of devastating earthquakes

tsunamis and volcanoes would be much

lower there would have been no Fukushima

Daiichi nuclear disaster in 2011 nor the

2004 Indian Ocean earthquake and tsunami

the

problem with overpopulation would also

not be as acute since there would be a

territory the size of India free for

humans to settle on on the other hand

were very lucky that the Ring of Fire

formed before Homo sapiens appeared the

active movement of tectonic plates was

most likely accompanied by a long

powerful earthquake that modern mankind

could not have survived plate movement

in this region continues to this day

which sometimes causes devastating

earthquakes and volcanic eruptions in

places where two tectonic plates collide

hot magma or lava is pushed to the

surface and this all happens over a

distance of 40,000 kilometers or 24,900

miles almost the length of the equator

the highest volcano of the Ring is in

the Andes ojos del Salado located on the

border of chile and argentina reaches a

height of six thousand eight hundred and

ninety-three meters or twenty two

thousand six hundred and fifteen feet

this volcano is considered dormant in

the entire history of their observation

of it researchers haven't seen a single

eruption however ojos del Salado is not

extinct

which means future eruptions are quite

likely a little to the north in Mexico

at an altitude of 5000 426 meters or

17,000 800 feet

sits one of the most dangerous volcanoes

of the Ring Popocatepetl the problem is

that about 20 million people live near

this active volcano in the event of a

sudden eruption the complete evacuation

of so many people would be simply

impossible further north about 13

volcanoes of the Ring are located in the

area ranging from the American state of

Oregon to the Canadian state of British

lombija one of them is mount st helens

not far from Seattle and Portland it's

known for its eruption in 1980 which

killed 57 people in Alaska in the

surrounding Aleutian Islands

there are about 52 volcanoes that make

up part of the Ring of Fire

however the Aleutian trench located

nearby in the Pacific Ocean is of great

danger its depth reaches about 7680

meters or about 25,000 200 feet this

trench has regularly been the source of

the most powerful earthquakes in history

including the great Alaskan earthquake

of 1964 which had a magnitude of 18

point for the largest number of

volcanoes in the ring is on the opposite

side of the Pacific Ocean one of them is

located 90 kilometers or 56 miles from

Tokyo we're talking about Mount Fuji a

sleeping volcano that has not erupted

since 1708 but this doesn't mean nothing

could ever happen again

most of the volcanoes belonging to the

Ring of Fire are in Indonesia there are

about 130 from the moment scientists

began observing the volcanoes 76 of them

have erupted about 1,100 times as a part

of the Zealandia continent New Zealand

wasn't spared volcanic activity the

highest local volcano Mount Ruapehu is

known for playing the role of a road

ruin the volcano on which frodo baggins

was to destroy the One Ring in the movie

The Lord of the Rings the same processes

within the Earth's crust both create and

destroy the emergence of an underwater

continent and the most powerful volcanic

eruptions and earthquakes are two sides

of the same coin for

the processes that seem to be destroying

our planet now will become the

foundation for something new in the

future what do you think let us know in
