the recent slowdown in booms is a piece of welcome relief for light sleepers and the easily startled.
Gas-X? 😁🤙
I wonder if the booms slowing down are related to “glacial rebound”. The massive ice pushed down on the earth and when it melted, the rocks rebounded, rising upwards. Sometimes this movement can cause small earthquakes, and I imagine even smaller fractures in the rock where the gas can escape. It wouldn’t surprise me that after 10,000 years the amount of movement has slowed.
