I think it is 7.1 if am true, and almost at the same time that of earlier, real hardship times for people of Nepal. 

Don't know.. In news it is still showing 7.4. 

Yes it was on almost same time, and as per prediction we can still more quakes is soon time..

A series of quakes took place with different intensities ranging from 7.1 to 7. 8 on the Richter scale. Earthquakes rocked Afhhanistan and China also but with less intensity.

Yes.. Outside Nepal its intensity has decreased. I saw in the news that in Delhi its scale was around 5. But still many felt it.

As I said, the intensity of the quakes varied frm region to region.

The intensity of quake is highest around its epicenter, and slowly all sorts of place the intensity of quake decrease around its spreading areas. 

Intensity of a quake reduces as it goes away from the epicenter.

Earthquake is intense violations of seismic conditions, inside crust of earth, which becomes kinetic energy at the surface. Tectonic plates are always moving inside crust of earth but they sometimes struck due to friction of its edges which causes earthquake. 

Friction between tectonic plates is the reason behind the earth quakes. This part is known. But how to act and what precautions are to be taken when an earth quake strikes is the vital part of the thread about which the link article dealt in detail in a layman's language in the link article .
