GPS Could Speed Tsunami Warnings and in addition GPS modules could be used to monitor the activity of volcanoes and landslides in real time. Findings in this direction were presented at the American Geophysical Union conference in San Francisco 5–9 December 2005 (a conference I have mentioned a couple of times earlier).
Epicentre and hypocentre. The hypocentre, more often called the focus, is the actual point where the earthquake starts (more or less deep underground), while the epicentre is the point on the earth's surface directly above the focus of the earthquake.
