所罗门群岛拉塔镇以西海域发生6.4级地震：震源深度17公里、无海啸威胁
美国地质调查局（USGS）测定，2026年11月9日03时34分59秒（UTC）所罗门群岛发生6.4级地震，震中位于该国 Temotu 省圣克鲁斯群岛拉塔镇（Lata）西南偏西30公里海域，震源深度17公里，震中坐标为南纬10.8669度、东经165.5616度。换算为所罗门群岛当地时间为11月9日14时35分，美西时间为11月8日19时35分。USGS 已对本次测定完成审核（reviewed）。
USGS 的 PAGER 灾损评估系统对本次地震发布绿色警报，意为出现人员伤亡与重大经济损失的可能性较低；USGS 事件页的海啸标志为0，太平洋海啸预警中心未发布海啸警报，马来西亚气象局亦表示本次地震对马来西亚无海啸威胁。截至发稿，未见人员伤亡与财产损失的报道。
中国地震台网最初测定本次地震为6.3级、震源深度10公里；各国台网对同一地震的初步测定存在差异，GSM 以 USGS 审核后的6.4级、深度17公里为准。

Magnitude 6.4 Earthquake Strikes West of Lata, Solomon Islands: 17 km Deep, No Tsunami Threat
The U.S. Geological Survey (USGS) recorded a magnitude 6.4 earthquake in the Solomon Islands at 03:34:59 UTC on November 9, 2026, with its epicenter 30 kilometers west-southwest of Lata, in the Santa Cruz Islands of Temotu Province, at a depth of 17 kilometers (10.8669 degrees south, 165.5616 degrees east). That is 2:35 p.m. local time on November 9 in the Solomon Islands and 7:35 p.m. Pacific time on November 8. The USGS solution has been reviewed.
The USGS PAGER system issued a green alert for the event, meaning a low likelihood of casualties and major economic losses. The USGS event page carries no tsunami flag, the Pacific Tsunami Warning Center issued no tsunami alert, and Malaysia's meteorological department said the quake posed no tsunami threat to Malaysia. As of publication, there were no reports of casualties or property damage.
China's earthquake networks initially measured the event at magnitude 6.3 with a depth of 10 kilometers; initial measurements by different national networks often differ, and GSM follows the reviewed USGS figures of magnitude 6.4 and 17 kilometers.
The Solomon Islands sit on the boundary between the Australian and Pacific plates, one of the world's most seismically active zones, and the Santa Cruz Islands area has seen repeated earthquakes above magnitude 6. (Source: U.S. Geological Survey)
