LUGANVILLE: A powerful earthquake struck near Vanuatu’s northern islands on Monday evening, with the U.S. Geological Survey reviewing the event at magnitude 7.3 and placing its epicenter about 35 kilometers northeast of Luganville. The quake hit at 8:44 p.m. local time, or 08:44 UTC, at a depth of about 116 kilometers, according to the agency. Vanuatu’s Meteorology and Geo-hazards Department separately listed the main shock at magnitude 7.2, reflecting differing early seismic calculations released after the event.
The epicenter was near Espiritu Santo island, home to Luganville, Vanuatu’s second-largest city and the main urban center of Sanma Province. Despite the strength of the tremor, Pacific tsunami bulletins said there was no tsunami warning, advisory, watch or threat in effect after the quake. There were no immediate confirmed reports of deaths or major damage in the hours after the shaking, while the first assessments focused on the area nearest the offshore epicenter and on any disruption to essential services.
USGS assigned the earthquake a green PAGER alert and reported very strong shaking near the epicenter. The quake struck offshore but close to Santo, one of Vanuatu’s most populated islands outside the capital region. Vanuatu lies on a highly active tectonic boundary in the South Pacific, where earthquakes and volcanic activity are recurring hazards across the archipelago. Strong quakes are closely watched because of the country’s dispersed islands, vulnerable infrastructure and exposure to both ground shaking and tsunami risk.
No tsunami threat issued
Tsunami statements issued after the quake consistently said there was no threat to coastlines, an important detail for a country where many communities, roads and maritime links are concentrated along the shore. The Pacific Tsunami Warning Center listed the event at magnitude 7.2 in its initial bulletin, while later reviewed data from USGS placed it at 7.3. The differing figures reflected separate seismic assessments published in the first hours after the earthquake, alongside updated calculations for depth and location as more readings were processed.
Vanuatu’s Meteorology and Geo-hazards Department showed that the main shock was followed by several additional tremors in the same region over the next few hours. Those included earthquakes ranging from magnitude 4.0 to 5.3 in the Vanuatu Islands area, according to the department’s March 31 update. The sequence underscored continued seismic activity around Santo and nearby islands, even as the absence of a tsunami alert and the lack of immediate confirmed major damage eased fears of a broader regional emergency.
Recovery remains a national focus
The latest earthquake struck as Vanuatu continues recovery work from the destructive magnitude 7.3 earthquake that hit near Port Vila in December 2024. That disaster killed 14 people, injured hundreds and damaged public buildings, roads, port facilities and other infrastructure in and around the capital. Since then, reconstruction and repair efforts have remained a central national priority, making any new major earthquake a matter of immediate concern for government agencies, businesses and communities across the island nation.
For now, the clearest confirmed outcome from the March 30 Vanuatu earthquake is that it delivered strong shaking near Luganville without triggering a tsunami warning and without immediate confirmed reports of heavy casualties or severe destruction. Seismic monitoring continued into Tuesday as aftershocks were recorded, while the initial picture remained one of a major offshore earthquake with limited early signs of widespread impact. The event again underscored Vanuatu’s exposure to powerful earthquakes in one of the world’s most active seismic zones. – By Content Syndication Services.
