Hairline horizontal cracks in plaster

firsttimebuyer15

I've noticed in the last few weeks that there are a few hairline cracks that run horizontally in both up and downstairs rooms. None of the cracks are bigger than 1-2mm but they seemed to have opened up a little more since the cold weather. I'm just curious as to how to monitor and what is the likely cause of horizontal vs vertical cracks? 

The house a 120 year old mid-terrace.

Have the walls been dot and dabbed, or are they wet plastered?

Im not sure if I'm honest. Is there a way for me to tell?

Any chance of a couple of photos

Possibly movement cracks given the recent bouts of cold weather?

This shows an example of one of the cracks. This is just under 1mm in width and runs in a horizontal line across the wall and around the chimney breast.

How high from the floor is this crack ?

it's about 3 feet above the floor and this is on the first floor but there is a couple of similar cracks on ground floor.
