Gravity alteration as extermination tool viable?

An alien race was rubbed the wrong way by humans being humans and decided that humankind has to go. However, unlike many other science fiction stories, they do not intend to give the humans even a semblance of a sporting chance by sending their equivalent of an invasion force. These aliens are capable of manipulating the fundamental interactions and instead have decided on using gravity as their tool.

Before humanity can realise the gravity of their situation, the aliens will flip a switch, at which point the strength of Earth's gravitational pull will be multiplied by 10 without any alteration of mass for a period of 24 hours. So for instance a person weighing 60kg will suddenly become 600kg with no prior warning and no other change. After this 24 hour period, Earth's gravity will return to its prior normal level of 1G.

Is this sufficient to guarantee the extinction of the human race? Will this also end all life as we know it on Earth?
