Mount Pelée (// pə-LAY; French: Montagne Pelée [mɔ̃taɲ pəle], meaning "bald mountain" or "peeled mountain") is a volcano at the northern end of Martinique, an island and French overseas department in the Lesser Antilles island arc of the Caribbean. Its volcanic cone is composed of stratified layers of hardened ash and solidified lava. The volcano has been dormant since its most recent eruption in 1932.

The stratovolcano's eruption in 1902 destroyed the town of Saint-Pierre, killing 28,000 people in the space of a few minutes, in the worst volcanic disaster of the 20th century. The main eruption, on 8 May 1902, left only two survivors in the direct path of the blast flow: Louis-Auguste Cyparis survived because he was in a poorly ventilated, dungeon-like jail cell; Léon Compère-Léandre, living on the edge of the city, escaped with severe burns. Havivra Da Ifrile, a young girl, reportedly escaped with injuries during the eruption by taking a small boat to a cave down the shore, and was later found adrift 3 km (1.9 mi) from the island, unconscious. The event marked the only major volcanic disaster in the modern history of France and its overseas territories.
Geographical setting and descriptionEdit
Mount Pelée is the result of a typical subduction zone. The subduction formed the Lesser Antilles island arc, a curved chain of volcanoes approximately 850 kilometres (530 mi) in length, between Puerto Rico and Venezuela, where the Caribbean Plate meets Atlantic oceanic crust belonging to the South American Plate. Other volcanoes in the island arc are also known for their volcanic activity, including Saint Vincent's La Soufrière, Guadeloupe's La Grande Soufriere volcano, Montserrat's Soufrière Hills, and the submarine volcano Kick 'em Jenny.
Volcanologists have identified three different phases in the evolution of Mount Pelée volcano: initial, intermediate, and modern. In an initial phase, called the "Paléo-Pelée" stage, Mount Pelee was a common stratovolcano. The cone of Paléo-Pelée was composed of many layers of lava flows and fragmented volcanic debris. Remains of the Paléo-Pelée cone are still visible at the northern view at the volcano today.
A second stage, now called the intermediate phase, started around 100,000 years ago, after a long period of quiescence. This stage is grouped by the formation of the Morne Macouba lava dome, then later on, the Morne Macouba caldera. During the intermediate phase, there were several eruptions which produced pyroclastic flows like those that destroyed Saint-Pierre in the 1902 eruption. Around 25,000 years ago, a large southwest sector collapse occurred, forming a landslide. This event is similar to the eruption of Mount Saint Helens in 1980.
The modern stage of the evolution of Mount Pelée has created most of the current cone, with deposits of pumice and the results of past pyroclastic flows. More than 30 eruptions have been identified during the last 5,000 years of the volcano's activity.
3,000 years ago, following a large pumice eruption, the Étang Sec (French for Dry Pond) caldera was then formed. The 1902 eruption took place within the Étang Sec crater. This eruption formed many pyroclastic flows and produced a dome which filled the caldera.
The following eruption in 1929 formed a second dome in the Étang Sec caldera, and produced pyroclastic flows emptying into the Blanche River valley. This last eruption is mainly responsible for the current state of Mount Pelée.

Before the 1902 eruption, as early as mid-1900, signs of increased fumarole activity were present in the Étang Sec (Dry Pond) crater near the summit. Relatively minor phreatic eruptions that occurred in 1792 and 1851 were evidence that the volcano was active and potentially dangerous. The indigenous Carib people knew it as "fire mountain" from previous eruptions in ancient times.
Eruptions began on 23 April 1902. In early April, excursionists noted the appearance of sulfurous vapors emitting from fumaroles near the mountaintop. This was not regarded as important, as fumaroles had appeared and disappeared in the past. On 23 April there was a light rain of cinders on the mountain's southern and western side, together with seismic activity. On 25 April the mountain emitted a large cloud containing rocks and ashes from its top, where the Étang Sec caldera was located. The ejected material did not cause a significant amount of damage. On 26 April the surroundings were dusted by volcanic ash from an explosion; the public authorities still did not see a reason to worry.
On 27 April several excursionists climbed the mountaintop to find Étang Sec filled with water, forming a lake 180 m (590 ft) across. There was a 15 m (50 ft) high cone of volcanic debris built up on one side, feeding the lake with a steady stream of boiling water. Sounds resembling a cauldron with boiling water were heard from deep underground. The strong smell of sulfur was all over the city, 6.4 km (4.0 mi) away from the volcano, causing discomfort to people and horses. On 30 April Rivière des Pères and the river Roxelane swelled, carrying boulders and trees from the mountaintop. The villages of Prêcheur and Sainte-Philomène received a steady stream of ash.
At 11:30 p.m. on 2 May the mountain produced loud explosions, earthquakes and a massive pillar of dense black smoke. Ashes and fine-grained pumice covered the entire northern half of the island. The explosions continued at 5–6 hour intervals. This led the local newspaper Les Colonies to indefinitely postpone a proposed picnic on the mountain, originally planned for May 4. Farm animals started dying from hunger and thirst, as their sources of water and food were contaminated with ash.
On Saturday, 3 May the wind blew the ash cloud northwards, alleviating the situation in Saint-Pierre. The next day the ash fall intensified, and the communication between Saint-Pierre and the Prêcheur district was severed. The ash cloud was so dense that the coastal boats feared to navigate through it. Many citizens decided to flee the city, filling the steamer lines to capacity. The area was covered with a layer of fine, flour-like white ash.
On Monday, 5 May, activity appeared to decrease, but at about 1:00 p.m., the sea suddenly receded about 100 metres (330 ft) and then rushed back, flooding parts of the city, and a large cloud of smoke appeared westwards of the mountain. One wall of the Étang Sec crater collapsed and propelled a mass of boiling water and mud (a lahar) into Blanche River, flooded the Guérin sugar works and buried about 150 victims under 60 metres (200 ft) to 90 metres (300 ft) of mud. Refugees from other areas rushed into Saint-Pierre. That night, the atmospheric disturbances disabled the electric grid, sank the city into darkness and added to the confusion.
The next day, at about 02:00, loud sounds were heard from within the depth of the mountain. On Wednesday, 7 May at around 04:00, activity increased; the clouds of ash caused numerous bolts of volcanic lightning around the mountaintop, and both the craters glowed reddish orange into the night. Through the day, people were leaving the city, but more people from the countryside were attempting to find refuge in the city, increasing its population by several thousand. The newspapers still claimed the city was safe. News of the volcano Soufrière erupting on the nearby Saint Vincent island reassured the people that the internal pressures in the mountain were being relieved. However, Captain Marina Leboffe, of the barque Orsolina, left the harbor with only half of his sugar cargo loaded, despite shippers' protests, clearance refused by the port authorities, and threats of being arrested. Many other civilians were refused permission to leave town. Governor Louis Mouttet and his wife stayed in the city. By the evening, the mountain's tremors seemed to calm down again.
On the morning of May 8, 1902, the night shift telegraph operator was sending the reports of the volcano's activity to the operator at Fort-de-France, claiming no significant new developments; his last transmission at 07:52 was "Allez", handing over the line to the remote operator. In the next second, the telegraph line went dead. A cable repair ship had the city in direct view; the upper mountainside ripped open and a dense black cloud shot out horizontally. A second black cloud rolled upwards, forming a gigantic mushroom cloud and darkening the sky in a 50-mile (80 km) radius. The initial speed of both clouds was later calculated to be over 670 kilometres (420 mi) per hour. The horizontal pyroclastic surge hugged the ground and sped down towards the city of Saint-Pierre, appearing black and heavy, glowing hot from the inside. It consisted of superheated steam and volcanic gases and dust, with temperatures exceeding 1,075 °C (1,967 °F). In under a minute it reached and covered the entire city, instantly igniting everything combustible.
A rush of wind followed, this time towards the mountain. Then came a half-hour downpour of muddy rain mixed with ashes. For the next several hours, all communication with the city was severed. Nobody knew what was happening, nor who had authority over the island, as the governor was unreachable and his status unknown.
There are unnamed eyewitnesses to the eruption, probably survivors on the boats at the time of the eruption. One eyewitness said "the mountain was blown to pieces, there was no warning," while another said "it was like a giant oil refinery." One said "the town vanished before our eyes." The area devastated by the pyroclastic cloud covered about 21 km2 (8 sq mi), with the city of Saint-Pierre taking the brunt of the damage.
At the time of the eruption, Saint-Pierre had a population of about 28,000, which had swollen with refugees from the minor explosions and mud flows first emitted by the volcano. Legend has previously reported that out of the 30,000 in the city, there were only two survivors: Louis-Auguste Cyparis, a felon held in an underground cell in the town's jail for wounding a friend with a cutlass, and Léon Compère-Léandre, a man who lived at the edge of the city. In reality, there were a number of survivors who made their way out of the fringes of the blast zone. Many of these survivors were badly burned, and some died later from their injuries. A number made their way to Le Carbet, just south of St. Pierre behind a ridge that protected that town from the worst of the pyroclastic flow; survivors were rescued on the beach there by Martinique officials.
Compère-Léandre stated the following when asked about his survival:
I felt a terrible wind blowing, the earth began to tremble, and the sky suddenly became dark. I turned to go into the house, with great difficulty climbed the three or four steps that separated me from my room, and felt my arms and legs burning, also my body. I dropped upon a table. At this moment four others sought refuge in my room, crying and writhing with pain, although their garments showed no sign of having been touched by flame. At the end of 10 minutes one of these, the young Delavaud girl, aged about 10 years, fell dead; the others left. I got up and went to another room, where I found the father Delavaud, still clothed and lying on the bed, dead. He was purple and inflated, but the clothing was intact. Crazed and almost overcome, I threw myself on a bed, inert and awaiting death. My senses returned to me in perhaps an hour, when I beheld the roof burning. With sufficient strength left, my legs bleeding and covered with burns, I ran to Fonds-Saint-Denis, six kilometers from Saint-Pierre.
One woman, a housemaid, also survived the pyroclastic flow but died soon after. She said that the only thing she remembered from the event was sudden heat. She died very shortly after being discovered. A third reported survivor was Havivra Da Ifrile, a 10-year-old girl who had rowed to shelter in a cave. Included among the victims were the passengers and crews of several ships docked at Saint-Pierre.
One passenger steamship, the Roraima, which went missing on 26 April, was believed to have been engulfed by ash from a preliminary explosion. However, it reached the port of Saint-Pierre at 06:30, shortly before the eruption, and was set aflame by the pyroclastic flow. It later sank; its wreck is still present offshore of Saint-Pierre. 28 of her crew, and all the passengers except two (a child and her creole nurse), were killed by the cloud.

At about 12:00 the acting governor of Martinique sent the warship Suchet to investigate what had happened and the warship arrived off the burning town at about 12.30. The fierce heat beat back landing parties until nearly 15:00, when the captain came ashore on the Place Bertin, the tree-shaded square with cafés near the center of town. Not a tree was standing; the denuded trunks, scorched and bare, lay prone, torn out by the roots. The ground was littered with dead. Fire and a suffocating stench prevented any deeper exploration of the burning ruins.
Meanwhile, a number of survivors had been plucked from the sea by small boats; they were sailors who had been blown into the water by the impact of the blast, and who had clung to wreckage for hours. All were badly burned. In the village of Carbet, shielded from the fiery cloud by a high promontory at the southern end of the city, were more victims, also badly burned; few of these lived longer than a few hours.
The area of devastation covered about eight square miles. Inside this area, the annihilation of life and property was total; outside was a second, clearly defined zone where there were casualties, but the material damage was less, while beyond this lay a strip in which vegetation was scorched but life was spared. Many victims were in casual attitudes, their features calm and reposeful, indicating that the eruption blast had reached them without warning; others were contorted in anguish. The clothing had been torn from nearly all the victims struck down outdoors. Some houses were almost pulverized; it was impossible even for those familiar with the city to identify the foundations of the city landmarks. The city burned for days. Sanitation parties gradually penetrated the ruins, to dispose of the dead by burning; burial was not possible given the number of dead. Thousands of victims lay under a shroud of ashes, heaped in windrows several feet deep, caked by the rains; many of these bodies were not retrieved for weeks, and few were identifiable.
The United States quickly offered help to Martinique authorities. On 12 May, US president Theodore Roosevelt instructed the Secretaries of War, Navy, and Treasury to start relief measures at once. U.S. cruiser Cincinnati, lying at Santo Domingo, and the Navy tug Potomac at San Juan, Puerto Rico, were ordered to proceed to the disaster area as soon as possible. President Roosevelt asked Congress for an immediate appropriation of $500,000 for emergency assistance to the victims of the calamity. The President said: "One of the greatest calamities in history has befallen our neighboring island of Martinique ... The city of St. Pierre has ceased to exist ... The government of France ... informs us that Fort-de-France and the entire island of Martinique are still threatened. They therefore request that, for the purpose of rescuing the people who are in such deadly peril and threatened with starvation, the government of the United States may send as soon as possible the means of transporting them from the stricken island." The US Congress voted for $200,000 of immediate assistance and set hearings to determine what larger sum might be needed when the full nature of the disaster could be learned. In an appeal for public funds the President empowered postmasters to receive donations for relief of the victims; a national committee of prominent citizens took charge of chartering supply ships.
On 20 May 1902, a second eruption similar to the first one in both type and force obliterated what was left of Saint-Pierre, killing 2000 rescuers, engineers, and mariners bringing supplies to the island. During a powerful eruption on August 30, 1902, a pyroclastic flow extended further east than the flows of 8 and 20 May. Although not quite as powerful as the previous two eruptions, the August 30 pyroclastic flow struck Morne Rouge killing at least 800, Ajoupa-Bouillon  (250 fatalities), and parts of Basse-Pointe (25 fatalities) and Morne-Capot, killing 10. A tsunami caused some damage in Carbet. To date, this was the last fatal eruption of Mount Pelée.
The study of the causes of the disaster marked the beginning of modern volcanology with the definition and the analysis of the deadliest volcanic hazard: pyroclastic flows and surges, also known as nuées ardentes (Fr: burning clouds). Eruptions of a similar type are now known as "Peléan eruptions". Among those who studied Mount Pelée were Angelo Heilprin and Antoine Lacroix. Lacroix was the first to describe the nuée ardente (pyroclastic flow) phenomenon.
The destruction caused by the 1902 eruption was quickly publicized by recent modern means of communication. It brought to the attention of the public and governments the hazards and dangers of an active volcano.
Mount Pelée continued to erupt until 4 July 1905. Thereafter, the volcano was dormant until 1929. On 16 September 1929, Mount Pelée began to erupt again. This time, there was no hesitation on the part of authorities and the danger area was immediately evacuated. Although there were pyroclastic flows, the activity was not as violent as the 1902 activity. It culminated in another "spine" or lava plug, albeit smaller than the 1902 plug, being emplaced at the summit. The activity ended in late 1932.
Beginning in October 1902, a large volcanic spine grew from the crater floor in the Étang Sec crater, reaching a maximum width of about 100 to 150 m (300 to 500 ft) and a height of about 300 m (1,000 ft). Called the "Needle of Pelée" or "Pelée's Tower", it grew in height by up to 15 m (50 ft) a day, reaching twice the height of the Washington Monument and more or less the same volume as the Great Pyramid of Egypt. It became unstable and collapsed into a pile of rubble in March 1903, after 5 months of growth.
The volcano is currently dormant. A few volcanic earthquakes occur on Martinique every year, and Mount Pelée is under continuous watch by geophysicists and volcanologists (IPGP). Before the 1902 eruption—as early as the summer of 1900—signs of increased fumarole activity were present in the Étang Sec crater (Scarth, p. 30). Relatively minor phreatic (steam) eruptions that occurred in 1792 and 1851 were evidence that the volcano was active. Signs of unrest are likely to precede any future eruptive activity from Mount Pelée, and its past activity (including the violent eruptions uncovered by carbon dating) is an extremely important factor for hazard assessment.
The city of Saint-Pierre was never fully rebuilt, though some villages grew up in its place. The estimated population of Commune of Saint-Pierre in 2004 was 4,544.

In this novel that retraces several generations of Martinique's history, Esternome, the protagonist of the novel's first part, witnesses firsthand the destruction caused by the volcano. Marie-Sophie Laborieux, Esternome's daughter and the novel's narrator, recounts her father's experiences and also discusses the traces of this event she has seen herself, including burn scars on her father's body and ossuaries in the ruins of Saint-Pierre. The eruption and its aftermath are discussed in the section "Amour grillée" ("Barbecued Love").
