Supposedly - scalar waves can be created using some type of equipment. Unlike regular waves - scalar waves are all spin and have no side to side or up down motion (think of a whirlpool that spins vs ocean waves that go up and down). The theory is that when two scalar waves meet (ie two whirlpools) they can interfere with each others spin thereby releasing the energy in them as regular waves that move up and down or side to side.

With regards to Fukushima, it's believed that the DS caused several scalar waves to meet up right at the weakest point in the fault line which caused the earthquake in Japan and the eventual meltdown.

Although I have heard about 'electrical' scalar waves - possibly being created by HAARP - which could heat the upper atmosphere and create/change storms and the directions they travel in; and about the possibility of using electrical scalar waves to melt rocks (near fault zones) deep underground which could cause earthquakes - I didn't know about the possibility of creating non-electric scalar waves such as those found on 11/11/2018

Either way - it's possible that they have some new technology which they are keeping under wraps. The biggest problem with electrical scalar waves though is that there is the possibility that we accidentally create a doomsday scenario. It seems that even creating small electrical scalar waves caused the sun to start belching solar flares in earth's general direction. Perhaps they have fine tuned their devices, but it still remains a possibility that misusing this technology (or using it incorrectly) can cause an extinction level event where the entire surface of the planet gets burned off. Followed by all of the hundreds of nuclear reactors going into meltdown mode making the planet uninhabitable for tens of millions of years... if we ever get the atmosphere back.
