Overview
- The USGS, which reported the event at 04:37 UTC Tuesday, located it 153 kilometers west of Neiafu at about 237 kilometers deep.
- The Pacific Tsunami Warning Center reported no tsunami threat because deep quakes rarely displace enough seawater to generate one.
- Tonga’s disaster office urged people in low-lying coastal areas to move inland or to higher ground and to avoid beaches until an all-clear.
- Early checks found no injuries or damage, and the USGS issued a Green alert that signals a low risk of casualties and economic losses.
- USGS estimates suggest about 21,000 people felt moderate shaking and 85,000 felt light shaking following a day-earlier M6.2 in this active stretch of the Pacific Ring of Fire.
