Nikola Tesla was a great Croatian engineer, inventor and a mad scientist who is widely known as the inventor of Alternating Current (AC) electric system. Throughout his career, Tesla discovered, designed and developed many ideas for several important inventions, most of which were officially patented by other inventors. Because he sold those inventions patent rights for money.
In 1893, Nikola Tesla became the owner of a patent for inventing a steam-powered-mechanical-oscillator. This invention was intended for generating electricity from the vibration generated in the oscillator machine. In 1898, Tesla finished his work on this oscillator. When he continued to test his new device in the presence of reporters, in his laboratory building at 48E. Houston, New York City, the device shook in such a way that it looked as if the building was about to collapse.
“I was experimenting with vibrations. I had one of my machines going, and I wanted to see if I could get it in tune with the vibration of the building. I put it up notch after notch. There was a peculiar cracking sound. I asked my assistants where did the sound come from. They did not know. I put the machine up a few more notches. There was a louder cracking sound. I knew I was approaching the vibration of the steel building. I pushed the machine a little higher. “Suddenly, all the heavy machinery in the place was flying around. I grabbed a hammer and broke the machine. The building would have been about our ears in another few minutes. Outside in the street, there was pandemonium. The police and ambulances arrived. I told my assistants to say nothing. We told the police it must have been an earthquake. That’s all they ever knew about it.”

Tesla smashed the oscillator machine with a hammer. Otherwise, there was such a jolt that it seemed as if the building would collapse right in front of their eyes. Meanwhile, the people who were inside the laboratory went out immediately. Those people thought the quack was caused by an earthquake. Police and ambulance came in an instant. However, Tesla called his assistants and warned them not to tell the police. Police were told the quack was caused by an earthquake.
Inspired by this incident, Tesla came up with the idea of a Tele-geo-dynamic oscillator. Nowadays, we use the Richter Scale for measuring the intensity of the earthquake, and it was developed based on Tesla’s Oscillator.
On the other hand, the HAARP(High-Frequency Active Auroral Research Program) is a secret program conducted by the US Department of Defense. Perhaps they tried to use Tesla’s Oscillator machine’s technology to make a machine to create an artificial earthquake or tsunami and they succeeded.

The machine that created a huge artificial earthquake on the Island of Haiti was also made from the model of the earthquake machine invented by Nikola Tesla. HAARP created a deadly weapon with this technology. The name of this weapon is “ Tectonic Weapon,” and this weapon is used for an Artificial earthquake, Tsunami or Disrupting communication in a region.
All of these wonders came into reality and it was made possible by the great scientist whom everyone knows as “The Dark Knight” of modern science and invention, Nikola Tesla.
