Since the occupation of the island of Martinique by European settlers, in 1635, there are 4 records of eruptions from Mt. Pelee volcano. 2 phreatic eruptions in 1792 and 1851, then 2 magmatic eruptions in 1902 and 1929.
However, thanks to the analysis of deposits, volcanologists have identified more than 30 major eruptions from the volcano in the past 5,000 years.

From March 1929, several witnesses reported an abnormal fumarollic activity at the summit of the volcano.
On August 16th, at about 9:45 pm, a sudden outburst threw a vapor column, and light ash falls over the settlements on the leeward side of mount Pelée. Some landslides were reported thereafter on the summit.
In the following weeks, the intensity of the observed phenomena decreased progressively.
On September 16th, 1929, at 10:00 pm, a violent eruption caused spontaneous evacuations of all the villages around the volcanoes. The population was allowed to return to their homes at the beginning of October, after an assessment made by a visiting geologist.
On October 14th, at 4:00 am, a new eruption, far more violent than the previous ones, threw dense ashfalls on Prêcheur.
The eruption of October 18th started at 1:00 am and covered the whole western side of the volcano with ashes.
On October 22nd, at 5:00 am a new eruption delivered a  pyroclastic flow (nuee ardente) which took 10 minutes to reach the sea along the Blanche river valley.  Mt. Pelee erupting, 1930
(ph. Perret / Carnegie Institution of Washington) The frequency of the eruptions then increased although they were less violent. The avalanches were caused by the collapses of a second dome growing in the caldeira. Similar avalanches occurred until December 1932 and all of them were travelling along the valley of the Blanche river.
