In order to make structures more seismic safe there are various ways by which one can build earthquake resistance structures which are far better than conventional ones.
The pyramidal or triangular shape structures contain less number of sides.A structure containing less number of sides frames greater resistance shape.
A rigid structure is more crumble and is more prone to annihilation.So the structure should be flexible.If we compare a taller building with a shorter one,the tall structure is more flexible.The shorter builds can not withstand the force of earth quakes.
During the construction of buildings,one should introduce the foundational plates .The layered foundational plates help buildings or other structures from destruction as they allow the sliding movement of the earth quake.

Answer:
the cosmic microwave background gives a snapshot of the universe when the temperature dropped enough to allow electrons and protons to form hydrogen atoms and by that making the universe nearly transparent to radiation as light was no longer scattered off free electrons.
Explanation:
the cosmic microwave background is the electromagnetic radiation filling all the space from the early stages of the universe and is the oldest dating to the epoch of recombination.
