Are there too many earthquake swarm around cratons co ok ak nv ca mo and do they indicate awaking of the supervolcano?

No. Earthquakes in California, Nevada, and Alaska are primarily the result of normal tectonic acitvity. Some earthquakes in Alaska and northern California are associated with volcanoes, but not supervolcanoes. Earthquakes in Colorado, Missouri, and Oklahoma are related to intraplate stresses and have nothing to do with volcanic activity. Some earthquakes in Oklahoma may be triggered by hydraulic fracturing used to extract oil and natural gas.

What are facts about the interior plains?
The Interior Plains Region is located in Canada and the United States. The Interior Plains were formed when cratons collided and welded together. The Interior Plains Region is mostly flat due to more than 500 million years of relative tectonic stability. The only exception to the flatness is the Black Hills of South Dakota. The Interior Plains region in Canada is called Canada's breadbasket. There are more than 4,000,000 people in the interior plains region. Metamorphic and igneous rocks now form the basement of the Interior Plains and make up the stable important elements of North America. The Interior Plains were covered by shallow inland seas. Sediments from the shield and the Rocky Mountains were deposited in these seas over millions of years.

How long ago did the earth crust cooled and harden?
It varies tremendously as new crust is being created all the time (for example at erupting volcanoes and mid-ocean-ridges) which are literally creating crust as you read this, up to the most ancient continental "cratons", the very ancient interiors of continents such as the Canadian shield which may be anywhere in the range from about 3.7 to 4.28 billion years.
How does erosion affect the earth's surface?
It gives it most of its topography - but over the Earth's life is also responsible for allowing terrestrial life to develop. Without erosion the basic "shape" of the landscape would otherwise be the flat, featureless plains of cratons, or rather ordinary-looking plateaux, hills and mountain-ridges lifted by tectonic processes. Erosion creates valleys etc - -but it also is responsible over geological time for creating sediment deposits that become sedimentary rocks. When in turn these are uplifted into hills and plateaux, their differing characteristics give differing erosion results, enriching the landscape's variety. It also creates the matrix of rock particles and soluble minerals needed as the basis of soil, necessary to support vegetation hence terrestrial life. In fact had their been no erosion at all since the planet formed, the landscape would be of nothing but igneous rock, and mostly bare rock at that. The only vegetation on land, if any, to have evolved would have been very highly-specialised algae and bacteria. But whence would they have drawn their nutrients? If their only source of food was the rock then that would have created a very slow form of erosion.
Where are the diamonds found?
The mineral diamond is found on earth where volcanic pipes have blasted it to the surface from where it is formed, deep within the earth's mantel. Diamonds have been found in India, Africa -- several countries -- Brazil, Canada, Australia and even in the United States. Geologists find 'trace minerals', including kimberlite, that may indicate -- about one in 200 times -- that diamonds are included in the volcanic situation. When water flows over the top of a diamond-producing volcanic pipe and tumbles diamond stones along, diamonds can be found in riverbeds, or at the mouths of rivers as they empty into salt water. When a productive volcanic pipe is located, the land owner may choose to mine the area for diamonds.
What is the geologic name of the areas with the least amount of earthquake activity?
Cratons, large geologically stable areas in continental interiors.
What do cratons do?
Cratons contain the ancient crust of igneous rocks.
The ancient continent cores are called?
cratons
What are cratons?
The part of a continent that is stable and forms the central mass of the continent; typically Precambrian.
What areas are dimonds mined from?
Old Continental cratons with diatremes or in sediments derived from such.
How do the sequence of sedimentary rocks in cratons differ from those in mountain belts?
The sequences of sedimentary rocks in cratons are typically thin and are relatively undeformed or gently warped. The sequences in mountain belts, meanwhile, are thick and extensively folded and faulted.

What are the ancient continent cores called?
Areas of ancient continental interiors are called cratons.
Do cratons contain diamonds if so how do they get there?
According to Wikipedia, a craton is an "...old and stable part of the continental lithosphere" -- the earth's outermost rocky shell. Kimberlite pipes, where diamonds are commonly found, are sometimes rooted in cratons. You can read more by following the link, below.
Where is kimberlite locations?
Kimberlite rocks are typically found in regions with ancient cratons, such as Africa, Canada, Russia, and Australia. These rocks are known for their diamond-bearing potential and are often associated with volcanic activity. Mining companies often search for kimberlite deposits as they can indicate the presence of diamonds.
Where on earth are diamonds normally found?
In old areas of continental crust called "cratons" in volcanic structures called "kimberlite pipes".
What are some facts about interior plains?
It was formed when cratons collided and welded together.I dont know if he is right but i think that he is really good I dont know what it means.
