After 15,000 years, it's waking up

Thermo variation occurs, heat melts ice, or its frozen elements.  Heat expansion occurs, I know this through Aerospace Industry.  Metal expansion occurs outward for outside diameters, inside squeeze or expands inward.  House 🏠 for example is heated during the day, and the temperature 🌡 drops wood boards shrink quicker than the steel nails and you'll hear the creaks on the ceiling. Starts to settle. The mountains I climbed in the morning, when the sun 🌞 comes up heats the rock formations.  Sun heats it up, which then causes rock pop or like small explosion.  Rocks then tend pop off the rock wall.  I have 360VR interactive footage of this occurring above me luckily, I had a helmet ⛑️ 📷 
Great show and overall an Awesome channel.
