The 2021 Eruption: A Timeline of Fire

The eruption at the Cumbre Vieja volcanic ridge, comprising the southern half of the Spanish island of La Palma in the Canary Islands, took place between September 19 and December 13, 2021. This event marked a significant period of intense geological activity, captivating the world's attention. Specifically, the volcanic eruption of La Palma in 2021 began on Sunday, September 19, 2021, at 2:10 PM local time, in the municipality of El Paso, near the village of Las Manchas on the island of La Palma. The initial eruption site was in the Montaña Rajada area, close to the town of El Paraíso, also within the municipality of El Paso.

When the Cumbre Vieja volcano erupted in September 2021, it released a horror of molten lava and poisonous gases, devouring houses and transforming the landscape. The lava flows were relentless, consuming everything in their path. Authorities on the Spanish island quickly declared a volcanic eruption, initiating emergency protocols to ensure public safety. The eruptive episode ended after almost three months, with the Instituto Geográfico Nacional (IGN) volcano observatory confirming that the activity at the volcano had ceased. This declaration on December 13, 2021, brought a collective sigh of relief, though the aftermath presented a new set of challenges.

The Geological Heartbeat of La Palma

La Palma, like the other islands of the Canary Islands archipelago, is a volcanic ocean island. These islands are formed by volcanic activity originating from a hot spot beneath the Earth's crust, leading to successive eruptions over millions of years. The La Palma volcano itself is a colossal structure, rising almost 7 km (4 mi) above the floor of the Atlantic Ocean, making it one of the tallest insular masses in the world when measured from its base. This immense scale underscores the sheer power and geological forces at play.

The 2021 eruption led to the formation of new geological features. The eruptions have created cinder cones and new lava deltas where molten rock flowed into the ocean. The new cone formed during the eruption has even been given a name: Tajogaite, or Tajogaite volcano. It is classified as a monogenetic volcano, meaning it originated from a single eruptive event, located in the municipality of El Paso. The volcanology institute INVOLCAN, in collaboration with INGV Catania, published a preliminary digital surface model (DSM) of the new cone, providing crucial data for scientists studying the volcano's evolution. This digital surface model of the new cone, updated on February 8, 2022, offers a detailed topographical map of the newly formed landmass, highlighting the dramatic changes to the island's geography.

Devastation and Resilience: The Human Cost

The human toll of the La Palma volcano eruption was immense. Hundreds of properties were destroyed, and thousands of people were forced to flee their homes after the volcanic eruption on La Palma in the Spanish Canary Islands. The images of houses covered with ash, or worse, completely engulfed by slow-moving rivers of lava, became a symbol of the disaster. A fissure was seen next to a house covered with ash on the Canary Island of La Palma, illustrating the immediate and overwhelming impact of the eruption.

Impact on Infrastructure and Livelihoods

The lava flows did not discriminate, consuming not only homes but also agricultural land, roads, and critical infrastructure. Banana plantations, a cornerstone of La Palma's economy, were obliterated, leaving many residents without their primary source of income. Roads were cut off, isolating communities and complicating evacuation and relief efforts. The sheer scale of destruction meant that entire neighborhoods ceased to exist, replaced by vast fields of solidified black lava. The emotional and psychological impact on those who lost everything was profound, necessitating extensive support and long-term recovery plans. The 2021 Cumbre Vieja volcano eruption notably destroyed over 300 homes in its path, but the actual number of affected properties grew significantly higher over the three months of activity.

The New Landscape Post-Eruption

Despite the devastation, the eruption also created new land. As lava flowed into the Atlantic Ocean, it solidified, extending the island's coastline and forming new lava deltas. While these new landforms offer scientific interest and potential for future ecological development, they also represent a stark reminder of the land that was lost. A series of maps and charts explaining what happened after an eruption in the Spanish Canary Islands became vital tools for authorities and the public to understand the progression of the lava flows and the areas affected. The new landscape, though scarred, embodies the duality of nature, as the French phrase beautifully puts it: "Le volcan La Palma, né en septembre 2021, incarne la dualité de la nature, détruisant et créant avec une force majestueuse." The La Palma volcano, born in September 2021, embodies nature's duality, destroying and creating with majestic force.

The Terrifying Tsunami Theory: Fact or Fiction?

One of the most widely discussed and often sensationalized aspects surrounding the La Palma volcano eruption was the terrifying tsunami theory put forward by some sources. This theory suggested that a catastrophic collapse of the volcano's flank could generate a mega-tsunami capable of devastating distant coastlines, particularly the east coast of North America.

Understanding the Speculation

The recent eruption on La Palma, in the Canary Islands, has stimulated speculation that the volcano might collapse, creating a tsunami that would devastate the east coast of North America. This idea is rooted in scientific studies that have identified potential instability in certain volcanic structures, including parts of Cumbre Vieja. The premise is that if a large section of the island were to suddenly slide into the ocean, it could displace an immense volume of water, generating a transoceanic tsunami. The concern gained traction partly due to the sheer size of the volcano and its steep slopes, which could theoretically facilitate such a collapse.

Scientific Consensus and Risk Assessment

While the concept of flank collapse and resulting tsunamis is a recognized geological phenomenon, the scientific community largely downplayed the immediate threat posed by the 2021 La Palma volcano eruption. Experts emphasized that such a catastrophic collapse, if it were to occur, would likely be preceded by clear geological warning signs over a long period, not spontaneously triggered by a relatively contained eruption. Furthermore, the scale and impact of any resulting tsunami would be highly dependent on numerous factors, making the "devastate the east coast" scenario highly improbable in the short term.

Leading volcanological and seismological institutes consistently stated that while the potential for flank collapse exists over geological timescales, there was no immediate evidence during or after the 2021 eruption to suggest such an event was imminent. The focus remained on monitoring the ongoing eruption and its direct hazards, rather than speculative, low-probability, high-impact scenarios. This distinction is crucial for maintaining public trust and avoiding unnecessary panic.

Netflix's La Palma: Disentangling Reality from Fiction

The La Palma volcano has gained significant attention in the highly anticipated Netflix series "La Palma," released on December 12, 2024. This blockbuster streaming series has been wowing audiences worldwide, leading many to question whether the disaster series is based on a true story. Indeed, Netflix's "La Palma" quickly became the No. 1 show in the U.S., fueling curiosity about its factual basis.

It is important to clarify: while La Palma isn't based on a true story in terms of its specific plot and characters, the stunning volcanic island is a real place — with a real disaster in its recent history. The Netflix series uses the dramatic backdrop of a volcanic eruption on La Palma as a setting for a fictional narrative. For instance, the show features a Norwegian family arriving for their seventh Christmas at a resort on the island of La Palma, with characters like Fredrik (Anders Baasmo) enjoying the familiarity of it all. These are fictional elements designed to create a compelling drama.

The series capitalizes on the public's awareness of the 2021 eruption and the associated tsunami theories, weaving them into a fictional disaster scenario. This has naturally led to questions like, "Did a volcano and tsunami really happen in La Palma?" The answer is nuanced: a real volcanic eruption did happen, causing immense destruction, and speculation about a potential tsunami exists in scientific circles, but a real, devastating tsunami caused by the 2021 eruption or an immediate future collapse did not occur. The Netflix show is a work of fiction that draws inspiration from real-world events and anxieties, rather than a direct retelling of the 2021 disaster.

Scientific Monitoring and Future Preparedness

The 2021 eruption underscored the critical importance of robust scientific monitoring and effective disaster preparedness. Institutions like the Instituto Geográfico Nacional (IGN) and the Volcanology Institute of the Canary Islands (INVOLCAN) played crucial roles in tracking the eruption's progress, issuing warnings, and providing vital data. Their continuous monitoring of seismic activity, gas emissions, ground deformation, and lava flow progression was indispensable for public safety and scientific understanding.

The collaboration between various scientific bodies, including INGV Catania (Italy's National Institute of Geophysics and Volcanology), in producing digital surface models of the new cone highlights the international cooperation essential for studying such complex natural phenomena. These models and a series of maps and charts explaining what happened after an eruption in the Spanish Canary Islands are invaluable for assessing long-term geological changes and planning for future events. The data collected from the La Palma volcano during and after the 2021 eruption will contribute significantly to global volcanological research, enhancing our ability to predict and respond to future volcanic crises.

Rebuilding and Recovery: The Road Ahead

For the residents of La Palma, the end of the eruption marked the beginning of a long and arduous recovery process. Rebuilding homes, infrastructure, and livelihoods in areas covered by meters of solidified lava presents unprecedented challenges. The Spanish government and regional authorities have committed to supporting the island's recovery, but the scale of the task is enormous. Many displaced families face an uncertain future, and the psychological scars of the disaster will take years to heal.

Efforts are underway to clear ash, establish new road networks over the lava flows, and explore innovative solutions for rebuilding. The resilience of the La Palma community, their strong ties to their land, and their determination to recover are evident. However, the path to full recovery will require sustained national and international support, careful urban planning, and a deep understanding of the new geological reality of the island. The La Palma volcano, though quiet now, remains a potent symbol of both destruction and the enduring spirit of those who call its slopes home.

Lessons from the La Palma Volcano

The 2021 La Palma volcano eruption serves as a powerful case study for understanding volcanic hazards, disaster response, and the interplay between scientific fact and public perception. It highlighted the unpredictable nature of volcanic activity, even in well-monitored regions.
