• Observatoire du Morne des Cadets

    The Morne des Cadets Volcanological Observatory, located on Morne Moustin since the 1930s, monitors Mount Pelée and seismic activity across Martinique. Built after the 1929–1932 eruption, it succeeded the first observatory erected in 1902 and abandoned in 1925. The site still houses a monumental, fully operational seismograph, one of the island’s earliest reinforced‑concrete structures.

The Montagne Pelée Volcanological Observatory, located on Morne des Cadets, is responsible for monitoring volcanic and seismic activity and conducting related research. After the 1902 eruption, Professor Alfred Lacroix had a small hut built on Morne des Cadets to serve as an observatory.

He worked there with a few geophysical measuring instruments, but as the volcano showed no further signs of activity, the decision was made to stop the observations. Four years later, the major 1929 eruption caused no casualties but did result in material damage.

A permanent observatory was then built and inaugurated on Morne Moustin, facing the historic installation on Morne des Cadets, from which it inherited its name.

Today, the observatory monitors not only the volcano but also the island’s subsurface seismic activity.

An information and exhibition room is open to the public during the observatory’s visiting hours.

The site has been listed as a Historic Monument since 2012.
