Israel says it destroyed Hezbollah's underground HQ in a blast felt like a 4.1 quake

The blast that shook the ground near the Israel-Lebanon border was not an earthquake, but it registered like one. Israel's military said it destroyed a major underground Hezbollah base in a powerful explosion that the US Geological Survey recorded as the equivalent of a magnitude 4.1 earthquake. The sheer force of the detonation, measured by a US government agency, underscores how far the conflict has moved beyond the limited exchanges of rockets and drones that defined the early months of the current escalation. For executives watching the region, the number is a useful proxy: this was not a pinprick strike, it was a deliberate attempt to erase a fortified command node from the battlefield.
