insane: Is it plausible for an earthquake shockwave to jave travelled that far in under a minute (assuming time is roughly synchronised)?
According to the interwebs, earthquake waves travel at about 8 km/sec. At that rate it would have taken about 45 seconds for it to reach my butt.
That speed (about 500 km/hour) is for earthquake waves in rock. I remember hearing that tsunami energy waves travel very quickly. Just checked and in water tsunami energy travels at around 800 km/hour.
Sometimes I just sit and think. Other times I just sit.
