What volcano erupted in the Caribbean in 2024?

Published in Caribbean Volcanic Activity 2 mins read

While no major volcanic eruption has been widely reported or confirmed for a Caribbean volcano in 2024, La Soufriere Volcano in St. Vincent and the Grenadines did exhibit significant signs of increased thermal activity in October 2024, prompting concerns.

Recent Volcanic Activity at La Soufriere (2024)

Despite the absence of a confirmed full-scale eruption, monitoring systems detected notable thermal changes at the summit of La Soufriere Volcano. This activity indicated increased unrest, leading to heightened vigilance among authorities and the public.

  • Detection Event: A low thermal anomaly was identified at the summit of La Soufriere. This signifies temperatures rising above existing background or baseline levels, indicating a potential increase in heat flow within the volcano.
  • Date of Detection: The anomaly was precisely detected on Sunday, October 6, 2024, at 2:38 p.m.
  • Detection System: The thermal signature was captured by the NASA FIRMS hot spot detection system, a satellite-based system used globally for monitoring thermal anomalies related to fires and volcanic activity.
  • Reporting Bodies: This crucial information was provided by the Seismic Research Centre and subsequently communicated by NEMO (the National Emergency Management Organisation) of St. Vincent and the Grenadines.
  • Implications: The detection of this thermal anomaly sparked fears of another volcanic eruption in St. Vincent, reflecting the volcano's inherent dynamism and the importance of continuous monitoring for public safety.

Understanding Volcanic Thermal Anomalies

A thermal anomaly is a critical indicator in volcanology. While it does not constitute an eruption, it suggests the movement of magma closer to the surface or increased hydrothermal activity within the volcanic edifice. Such anomalies can often precede an eruption, making their detection vital for early warning systems and for guiding emergency preparedness measures. Continuous monitoring of these subtle changes is essential for assessing a volcano's state and forecasting potential hazards.
