As reported by our readers, the USGS ShakeMap gives a strong intensity for the whole island. This can cause moderate damage to buildings. So far, no reports indicate any damage or destruction.

A magnitude 7.1 earthquake occurred only a few km north of Guam, according to preliminary USGS data. The hypocenter was located in a depth of approx. 130 km. This makes the earthquake less dangerous and reduces the chance for a tsunami. NO warnung was issued, althouth small, non-destructive waves along the coast of Guam can not be excluded.

The shaking of the earthquake was felt very strongly on Guam, according to reports we received.
