23 May
Summary
- A magnitude 6.0 earthquake struck Hawaii island's western flank.
- The U.S. Geological Survey upgraded the quake's magnitude.
- The Pacific Tsunami Warning Center confirmed no tsunami was generated.

A significant earthquake with a magnitude of 6.0 occurred on the western flank of Mauna Loa on Hawaii island late Monday night. Initially assessed at a magnitude 5.9 by the U.S. Geological Survey, the tremor's strength was later upgraded. This seismic activity prompted immediate concern regarding potential tsunamis.
However, the Pacific Tsunami Warning Center swiftly assessed the situation and confirmed that the earthquake did not generate any tsunami. The quake was centered approximately 8 miles south of Honaunau-Napoopoo and was felt across all the Hawaiian islands, including Maui and Oahu, with strong shaking reported in some areas. A magnitude 3.2 aftershock followed the main event about six minutes later, further reinforcing the focus on public safety.
