Asteroid impact damage from the Planet X system
David Meade
In this article, we’ll look at a variety of expert opinions on the catastrophic earth damage from the flyby of a Near Earth Object such as the Planet X system.

Abbott believes that a space object
about 300 meters in diameter hit the Gulf of Carpentaria, north of
Australia, in 536 A.D. An object that size, striking at up to 50,000
miles per hour, could release as much energy as 1,000 nuclear bombs.
Debris, dust and gases thrown into the atmosphere by the impact would
have blocked sunlight, temporarily cooling the planet—and indeed,
contemporaneous accounts describe dim skies, cold summers and poor
harvests in 536 and 537. “A most dread portent took place,” the
Byzantine historian Procopius wrote of 536; the sun “gave forth its
light without brightness.” Frost reportedly covered China in the
summertime. Still, the harm was mitigated by the ocean impact. When a
space object strikes land, it kicks up more dust and debris, increasing
the global-cooling effect; at the same time, the combination of
shockwaves and extreme heating at the point of impact generates nitric
and nitrous acids, producing rain as corrosive as battery acid. If the
Gulf of Carpentaria object were to strike Miami today, most of the city
would be leveled and the atmospheric effects could trigger crop failures
around the world.
Asteroid Strikes – Impact – Ocean Strikes/Mega-Tsunamis
A large ocean strike would create tsunamis more than a mile high that would make it hundreds of miles inland.

Defense Conference, 5-9 March 2007 (Washington, D.C.). [Online] Tsunami Threats from a Large Asteroid
Since 72% of the Earth’s surface is
covered with oceans, there is a 72% random probability that a comet or
asteroid impact will occur in the ocean. An ocean impact would excavate a
large transient cavity approximately 20 times the diameter of the
impactor.
An ocean impact will create a
compression wave in the water. The compression wave may be sufficient
to implode deeply submerged objects, such as submarines.
A large ocean impact will produce a large tsunami. Tsunami
is Japanese for “harbor wave.” Tsunami generally travel quickly across
the ocean, typically at speeds of 380 mph (0.17 km/s). In deep water,
the impact tsunami height might be several thousand feet high for a
Cretaceous/Tertiary (K/T) size impactor, but the height may increase
dramatically as the waves reach the shoreline because the wave slows in
shallow water and the energy becomes more concentrated. The impact
tsunami may produce several mile-high wave fronts that could travel
several hundred miles inland. Tsunamis are of concern because they
propagate over great distances and much of the world’s populations are
located near coastal regions.
What mitigation? – A strike will shut down all global communications.

Threat Impact Analysis,” Paper presented at the 2007 AIAA Planetary
Defense Conference, 5-9 March 2007 (Washington, D.C.). [Online] Communications Cut Down by Asteroid Strike
Large quantities of ionizing radiation
will be produced by the impact and can severely change the environment
of the upper atmosphere, producing heavily ionized regions, which can
disrupt electromagnetic waves passing through those zones. The trapping
mechanism for these high-energy electrons may be similar to that which
produces the Van Allen radiation belts. This radiation will cause
significant interruption of communications. This will interfere with all
surviving telephone, television, computer and radio traffic. There will
be so much static in the signal that it will be almost unintelligible.
For a large impact, these disturbed regions can easily be global in size
and can persist for tens of hours. This could essentially temporarily
shut down all worldwide communications.
Asteroid Strikes
Recovery from a large strike would take thousands of years.

Defense Conference, 5-9 March 2007 (Washington, D.C.). [Online] Asteroid Strike Causes Volcanism
A deep impact produces two zones of
destruction: one at the point-of-impact and the other on the opposite
side of the globe. The destruction at the point-of-impact produces a
regional area of great devastation that wrecks havoc for several days.
The shockwave from the impacts traveled through the Earth fracturing the
Earth’s crust on the opposite side of the planet, producing a jumbled
debris field and triggering massive mantle plume volcanism. The area of
devastation on the opposite side of the Earth is significantly greater
and the devastation is long-term extending thousands of years. It is
this component that produces global devastation by releasing massive
quantities of volcanic magma, which in turn generates acidic and
poisonous gases. The gases combine with moisture to form acids that are
primarily responsible for extinguishing life across the entire planet.
The gas generation is also responsible for the drawdown of oxygen levels
below minimally acceptable levels. These deep impacts are not random;
rather, they occur with regularity in geological time.
