Earthquake aftershocks

[Will storm]

I was up watching Tv on the 21st August early on about 4:37 and I saw my glass of water ripple for about 5 seconds along with my lamp shade swaying very slightley. I thought it was just me but I just went on the british geological survey website I saw that there had been a 1.5 magnitude earthquake 1/4 mile from my village. I also felt 2.8 magnitude earthquake on the 5th April. There have been many small aftershocks from the main quake on the 27th Feb but there was a lull in activity after April 8th with near nothing. Why in July and August has the activity picked up again? Are these separate events or are they still related to the main quake?

you would think separate due to length of time in between

You must be pretty observant to notice a quake of only 1.5!

I remember hearing something earlier this year, about how there hadn't been any earthquakes in that particular area for a long time and that perhaps Februarys earthquake has reactivated and an old fault, so perhaps it's just normal background activity?
