Welcome to the Vanuatu Geohazards Observatory Website (VGOW)
Welcome to the Vanuatu Geohazards (Volcanoes, Earthquakes and Tsunamis) Observatory homepage.
This site provides access to information about ongoing geophysical survey and research on Vanuatu. It is our goal to provide as much resource in information as possible, about all the programs of the Vanuatu Geohazards Observatory, within Vanuatu Meteorological and Geohazards Department.
The site is not designed to be exceedingly technical, but rather, suitable, useful and interesting to both the general public and to the scientific community.

|VVAL ||Frequently Active Volcano Group (Yasur, Lopevi, Ambrym)||'Dormant' Volcano Group (Ambae, Gaua, Vanua Lava) |
| || || |
|Lvl.?||Insufficient Monitoring to make assessment |
|Lvl.0||Normal low-level activity.||Normal, quiet.|
|Lvl.1||Increased activity, danger near crater only.||Signs of awakening.|
