Weird banging noises @ 4 different corners at a time in the sky lasting for 10-15 min.

Heard what sounded like weird banging noises at four separate corners of the sky, each taking turns banging. It was nothing we had ever heard and as consistent as a heart beat. Almost like thunder but each was about 10 seconds’ apart give or take. This lasted for about 10 to 15 min. It sounded like the ground was thumping.
