- Mount Pelée is showing renewed seismic activity after decades of dormancy, with a significant spike in earthquakes recorded in July 2026.
- In July 2026, 331 volcanic earthquakes were recorded, averaging 85 per week, with 124 earthquakes detected in the week ending July 31, nearly triple the previous week's 45.
- Since May, there has been several inches of ground movement near the summit, with the surface shifting at close to half an inch per month.
- The alert level for Mount Pelée is currently at YELLOW, indicating elevated unrest, but the observatory states that the probability of eruptive activity in the short term remains low.
- The 1902 eruption of Mount Pelée killed around 30,000 people and completely destroyed the town of Saint-Pierre.
- The last eruption of Mount Pelée occurred between 1929 and 1932, marking a long period of dormancy until recent activity.
- Since 2019, unrest has been fueled by a network of superheated water and steam beneath the volcano.
Mount Pelée, located in Martinique, is awakening from decades of dormancy, raising alarms due to its catastrophic history, including the 1902 eruption that killed 30,000 people in minutes. Recent seismic activity has seen 124 earthquakes recorded in the last week of July, nearly triple the previous week.123489
The Martinique Volcanological and Seismological Observatory reported that the volcano has been relatively quiet since 1932, making the recent activity concerning. The earthquakes, averaging 85 per week in July, are linked to magma or pressurized fluids fracturing rock beneath the volcano. Although none exceeded magnitude 1, experts are closely monitoring the situation.
Ground deformation has also been observed, with the summit inflating due to pressure about 0.6 miles below the surface. The observatory stated, "The probability of eruptive activity in the short term remains low. However, considering the observations accumulated over the past months and years, an evolution of the situation in the medium term (weeks to months) cannot be excluded."67
The alert level for Mount Pelée is currently set at YELLOW, indicating elevated unrest. While officials have not issued warnings of an imminent eruption, scientists emphasize the need for continued observation to assess whether the pressure beneath the volcano is subsiding or increasing.
A major eruption could have devastating effects, sending clouds of gas and ash across northern Martinique and disrupting air travel in the Caribbean.
“The Martinique observatory recorded 331 volcanic earthquakes in July, with 124 in the final week—nearly triple the prior week's 45—though none exceeded magnitude 1. Ground movement near the summit, linked to a pressurized source 0.6 miles below, has slowed slightly, but experts say several more weeks of observation are needed to confirm pressure is easing.”
