The Israel Defense Forces blew up a 1.2 mile-long Hezbollah tunnel filled with weapons and supplies near the border, with the blast so powerful that it triggered earthquake alarms on Saturday.

The IDF said the tunnel was just one of several located in southern Lebanon that was being prepped for Hezbollah’s elite Radwan forces to one day invade Israel in an attack similar to the Oct. 7 massacre.

Inside the tunnels, Israeli troops found AK-47 rifles, explosives, rocket launchers, sniper rifles and anti-tank guided missiles and launchers.

The soldiers also found a massive stash of food, including canned goods, chocolates and even pickled olives — with enough goodies to feed more than 100 fighters, the IDF said.

The base had working electricity and plumbing, along with several bedrooms and bathrooms for the terrorists.

Officials said they discovered the tunnel during a 48-hour operation in southern Lebanon, where Israeli forces battled with Hezbollah fighters stationed near the tunnel system.

After killing off the terrorists – along with four other Hezbollah operatives at a nearby, smaller tunnel – the soldiers made their way inside the 1.2 mile-long underground base.

The tunnel was filled with Hezbollah’s booby traps and mines, with IDF troops successfully clearing them out so its forces could investigate.

The IDF then lined the tunnel system with about 400 tons of explosives and blew it up on Saturday, with the force so great that false-earthquake alarms were set off across northern Israel.

The massive seismic activity was detected across 284 communities in Israel and the West Bank, according to the Jerusalem Post.

A similar incident unfolded in Russia last month when a Ukrainian drone struck a weapons depot in Toropets, with the immense blast registering on earthquake monitoring stations across the region.

Along with the tunnel destroyed on Saturday, the IDF has allegedly flagged at least three Hezbollah tunnels that were being prepped for the terror group’s alleged “Conquer the Galilee” operation, which Israel said involved an invasion over the border.

The existence of the tunnels so close to the border is a clear violation of the UN Security Council’s Resolution 1701, which ended the Israeli-Lebanon war in 2006 and created a buffer zone along the border where the IDF and Hezbollah were prohibited from operating in.
