Seismic direction reversed now South to East

Today at around 11:12 Hrs IST (+5:30 GMT) I felt seismic activity of low intensity and I noticed that it had reverse direction than the seismic tremors I have felt few days back.

Direction : going from South (approx. 40 degrees in West) towards East (approx. 10 degrees in North)
nature : Shortwave (rapid bumps)
intensity : low
duration : 20 sec approx.

I have made an illustration of seismic activity on Globe map posted here under
