Is it possible to reduce earthquakes by reducing tension between tectonic plates in fault lines?
It would require an insane amount of energy to cause a slip to occur, more than we have at our disposal in our nuclear arsenal. And, if we did have enough nuclear bombs, we don't even know if we would be successful. Nor would we want to release that much radiation on our planet all at once.
Earthquakes can't be moderated. We can't control the amount of tension between the tectonic plates, nor can we cause it to be released at any given time. All we can do is understand where earthquakes likely occur, how often, and at what magnitude, and then prepare accordingly.
Well, there could be a gigantic earthquake underwater everywhere at the same time, creating gigantic tsunamis that would wipe over the continents, sweeping everything into the ocean.
Or, the same earthquake would happen but this time the salt water from the ocean would sweep over the polar icecaps, then the salt from the ocean would cause all the ice to melt thus rising the water levels high enough to drown everything, from plants to animals to humans (without plants land animals will have nothing to eat).
Then, once all the land animals are dead, the tectonic plates suddenly pull apart, causing the water to sink and evaporate in the heat of the earth's core, thus killing every, sea animal. And with the heat of the earth gone (lost it while heating up all the sea water), earth slowly dies. :(
A divergent margin is another term for a mid-ocean ridge or a rift valley.
At divergent margins, plates move apart and new crust and lithosphere are created. This usually occurs at a Mid-Ocean Ridge, but divergent margins can also occur on land. The Great Rift Valley of Africa is a example of a divergent margin that is splitting the African Continent into two parts.

Is there a blank tectonic plates map on the internet?
It is harder than I imagined to find such a map. However, the website below has a really good interactive map, that you can add and remove layers from, so you can remove the plate names, or any other layer. Give it a try.
They produce Earthquakes when they collide
The largest plate The Circum-Pacific Belt or the Pacific Ring of Fire has the most violent and aggressive volcanoes than others.
They slide in the Asthenosphere which is a Hot Plastic Zone.
They cause Himalayas , The Andes Mountains To form .
They sometimes create tall mountains
A tectonic plate is a piece of the Earth's crust and uppermost mantle (together referred to as the lithosphere). The surface of the Earth consists of ten major tectonic plates and many more minor ones.
The plates are around 100 km (60 miles) thick and consist of two principal types of material: oceanic crust (also called sima from silicon and magnesium) and continental crust (sial from silicon and aluminium). Under both lies a relatively plastic, although non-molten, layer of the Earth's mantle called the asthenosphere.
The composition of the two types of crust differs markedly. Oceanic crust consists largely of basaltic rocks ("mafic"), while the continental crust consists principally of lower density granitic rocks rich in aluminium and silica ("felsic"). The two types of crust also differ in thickness, with continental crust considerably thicker than oceanic.
The churning of the asthenosphere carries the plates along in a process known as continental drift, which is explained by the theory of plate tectonics. Interaction between the plates creates mountains and volcanoes, as well as giving rise to earthquakes and other geological phenomena.
The boundaries of the plates do not coincide with those of the continents. For instance, the North American Plate covers not only North America, but also far eastern Siberia and northern Japan.
As far as is known, the Earth is the only planet in the Solar System to possess active plate tectonics, although there are suggestions that different styles of plate tectonics were in operation on Mars, Venus, and some of the Galilean satellites in the past.
