Mega-Tsunami Warning: 1,000-ft Wave Could Devastate Atlantic Coast

A potential mega-tsunami, triggered by a volcanic eruption on the island of La Palma in the Canary Islands, could send a 1,000-foot wave across the Atlantic, devastating the eastern seaboard of the United States, according to some scientists.

The long-dormant Cumbre Vieja volcano on La Palma is the focal point of concern, with a flank of the island potentially prone to collapse into the ocean, unleashing a massive displacement of water. While the likelihood of such an event is debated and the timing remains uncertain, the potential consequences are significant enough to warrant attention and further research, according to the original reports that resurfaced this week.

The scenario, initially explored in a 2001 study by Steven Ward and Simon Day at the University of California, Santa Cruz, posited that a substantial portion of the island’s western flank could detach and plunge into the Atlantic Ocean. This catastrophic landslide would generate a mega-tsunami, dwarfing typical tsunami events caused by earthquakes. The wave’s immense size and energy could allow it to traverse the Atlantic, impacting the coasts of North and South America, as well as parts of Europe and Africa.

While the 2001 study gained considerable attention, it also sparked debate within the scientific community. Some researchers argue that the original model overstated the potential for a single, massive landslide, suggesting that a more gradual and fragmented collapse is more likely. This would still generate a significant tsunami, but one considerably smaller and less devastating than the 1,000-foot mega-tsunami.

Despite the differing opinions on the scale of the potential event, the underlying concern remains valid: volcanic activity on La Palma poses a legitimate tsunami risk. The island has experienced eruptions in recent years, including the 2021 eruption that lasted for several months, causing widespread damage and displacement. This recent activity underscores the dynamic nature of the island and the need for ongoing monitoring and risk assessment.

The potential impact of a mega-tsunami on the U.S. East Coast is difficult to fully comprehend. A wave of that magnitude could inundate coastal communities, destroy infrastructure, and cause widespread loss of life. Cities like Miami, New York, and Boston, with their dense populations and low-lying coastal areas, would be particularly vulnerable. The economic consequences would be staggering, potentially disrupting global trade and causing trillions of dollars in damage.

The key factors influencing the size and impact of a potential tsunami include the volume of the landslide, the speed at which it enters the water, and the bathymetry (underwater topography) of the ocean floor. These factors would determine the wave’s initial height, speed, and direction, as well as how it propagates across the Atlantic.

“The specific characteristics of the landslide would have a significant impact on the tsunami’s characteristics,” said a tsunami expert not connected to the original Yahoo! article. “A slower, more fragmented collapse would generate a smaller, less energetic tsunami compared to a rapid, massive landslide.”

Ongoing research and monitoring efforts are crucial for understanding the potential risks associated with Cumbre Vieja and other volcanically active islands. Scientists are using a variety of techniques, including satellite imagery, GPS measurements, and seismic monitoring, to track the volcano’s activity and assess the stability of its flanks.
