Photo captured by Senior Seismic Technician on 29th December 2020 shows new dome (with steam) in crater following an effusive eruption


At Morne Ronde 18 earthquakes were felt on April 29th and the Crater Lake was observed to be steaming with emissions seen from Wallibou and Richmond. Earthquakes were felt on the north side of the volcano, particularly strong on the west coast at Morne Ronde and increased in number and intensity.

On Monday, 30th May 2005, the Seismic Research Unit in collaboration with the Soufriere Monitoring launched the Volcanic Hazard Atlas of the Lesser Antilles, the first of its kind in the world.  This comprehensive reference text on volcanism in the Lesser Antilles provides an up-to-date summary of the current understanding of the evolution of West Indian volcanoes. It is pertinent to a broad audience ranging from island residents wanting to learn about nearby volcanoes to volcanologists from other regions interested in these impressive volcanoes.

A volcano is a mountain that opens downward to a reservoir of molten rock below the surface of the earth. Unlike most mountains, which are pushed up from below, volcanoes are vents through which molten rock escapes to the earth's surface. When pressure from gases within the molten rock becomes too great, an eruption occurs. Eruptions can be quiet or explosive. There may be lava flows, flattened landscapes, poisonous gases, and flying rock and ash that can sometimes travel hundreds of miles downwind.

Before a Volcanic Eruption:

The following are things you can do to protect yourself, your family and your property in the event of a volcanic eruption.

During a Volcanic Eruption:

Follow the evacuation order issued by authorities and evacuate immediately from the volcano area to avoid flying debris, hot gases, lateral blast and lava flow.

Be aware of mudflows. The danger from a mudflow increases near stream channels and with prolonged heavy rains. Mudflows can move faster than you can walk or run. Look upstream before crossing a bridge and do not cross the bridge if a mudflow is approaching.
Avoid river valleys and low-lying areas.

After a Volcanic Eruption:

Go to a designated public shelter if you have been told to evacuate or you feel it is unsafe to remain in your home. Find your local shelter here (linked to local shelter section)

Local authorities may not immediately be able to provide information on what is happening and what you should do. However, you should watch TV, listen to the radio or check the Internet often for official news and instructions as they become available.
