Earthquake Alerts in Northern Israel Mistakenly Triggered by Controlled Explosions in Lebanon
In a startling turn of events, a wave of earthquake alerts swept across northern Israel early this morning, October 26, 2024, impacting communities in regions like Haifa and the Golan Heights. However, residents soon learned that this was not due to tectonic activity. Instead, the alerts were mistakenly activated by an explosion in southern Lebanon. This blast, confirmed as a controlled detonation linked to Israeli Defense Forces (IDF) operations, was initially detected by Israel’s advanced earthquake alert system, Teru’a, which mistook the seismic energy from the explosion for an earthquake.
The Teru’a system, launched in 2022, is renowned for its sophisticated sensors and ability to distinguish between explosions and genuine seismic events. However, today’s blast was particularly close to a sensor, leading to a mistaken reading. The Geological Institute of Israel explained that the system’s automatic response distributed earthquake alerts to nearly 300 communities across northern Israel and the West Bank, prompting an outpouring of concerned reactions from citizens who initially feared an imminent natural disaster.

Responding to the widespread alerts, the IDF clarified that there was no threat to public safety and confirmed that the explosion sounds were tied to military operations in Lebanon, not to any form of security breach. Even international monitoring networks, including European systems, initially registered the explosion as seismic activity, adding to the initial confusion.
Residents in Haifa and surrounding areas recounted moments of alarm as their phones issued urgent earthquake warnings, advising them to take immediate safety measures. This misinterpretation understandably led to heightened anxiety, as the region holds a longstanding belief that a major earthquake is due in the near future. Israel’s history of seismic activity includes significant quakes approximately once a century, with the last major one occurring 96 years ago in 1927.
The Teru’a system’s success is vital to Israel’s readiness for seismic events, and maintaining its functionality remains a priority for public safety. When the system launched, Professor Zohar Gvirtzman, Director of the Geological Institute, emphasized that sustained funding is critical for the system’s maintenance and upgrades to ensure it can continue to serve as a reliable safeguard. Despite today’s unusual scenario, Teru’a’s development is a crucial step in earthquake preparedness in Israel, a region where seismic events are historically rare but potentially severe.
Today’s events highlight the heightened alertness of both the public and Israeli authorities, underscoring the importance of this system’s accuracy in emergencies. While today’s mistaken alerts caused widespread disruption, they serve as a powerful reminder of the need to remain vigilant and prepared for real seismic threats that may occur in the future.
