Grenada

Located in the northern region of Grenada is the island’s only ‘live’ volcano, Mt. St. Catherine. This volcano has not erupted in historic time, but has the potential to erupt in the future. Download the full Grenada chapter.

Martinique

Martinique consists of several juxtaposed volcanic centres that belong to the old external arc and the young internal arc (end of Oligocene to present). Montagne Pelée, located in the northern part of the island, is the only active volcano. Download the full Martinique chapter.

Montserrat

Montserrat has one active volcanic centre, the Soufrière Hills Volcano. The volcano is formed of a cluster of andesite domes with flanks of associated pyroclastic deposits and volcaniclastic sediments and has an active history that can be traced back at least 175 ka.

Nevis

The entire island of Nevis is a single volcano with Nevis Peak being the main volcanic centre. Very little is known about the volcanic history of Nevis, though Nevis Peak did erupt significantly in the past to create the large domes present there today. Download the full Nevis chapter.

Saba

The island of Saba is a complex stratovolcano composed of over 20 andesitic domes produced by Pelean-style eruptions. Other eruptive styles have occurred in the past, but these are represented by only a small percentage of the island’s stratigraphy. Download the full Saba chapter.

St. Eustatius

The Quill on St. Eustatius is a young, central vent stratovolcano, almost entirely composed of pyroclastic deposits representing Pelean-, St. Vincent- and Plinian-style activity. Six recently drilled water wells on the flanks of The Quill have revealed heated groundwater suggesting that the volcano is potentially active. Download the full St. Eustatius chapter.

St. Kitts

Mt. Liamuiga rises to a height of 1155 m (3792 ft) and has a summit crater ~900 m wide and 244 m deep. The summit of Mt. Liamuiga exposes remnant lava flows and/or domes but the most common deposits identified on the lower flanks of Mt. Liamuiga are pyroclastic deposits. Download the full St. Kitts chapter.

Saint Lucia

The Soufrière Volcanic Centre, located in the southwestern region of the island, is the focus of the most recent volcanic activity in Saint Lucia. Download the full Saint Lucia chapter.

St. Vincent

La Soufrière is the youngest volcanic centre on St. Vincent. It occupies the northernmost third of the island and is considered to be the only volcano that is likely to erupt in the future. Download the full St. Vincent chapter.
