The core of the Earth is a wildly hot and tempestuous place, which radiates massive amounts of heat. This heat is significant enough to move tectonic plates in such a way.
Radio waves (similar to electromagnetic radiation) travel at the same speed of light, that is 300,000 km/second.
Jupiter being at 630,000,000 km from earth, the time needed to get the radio waves on earth = 630,000,000/300,000 = 2,100 sec or 35 minutes
