A 7.0 magnitude earthquake struck offshore in the Solomon Islands. While there are no reports of injuries, there are reports of damage in Honiara and power is reported to be out in some areas and radio services are off the air. The earthquake was followed by at least three aftershocks in the same area, the largest a magnitude 6.0. There are no current Tsunami warnings in effect.
Another very deep M7.0 earthquake occurred south of the Fiji Islands at a depth of 578.2 km (359 miles). The earthquake was followed by a few aftershocks (M4.4 - M5.1). This is the third cluster of earthquakes that have occurred in this region in the past week. The epicenters were located about 334 km (207 miles) SE of Levuka, Fiji and 348 km (216 miles) WNW of Nuku‘alofa, Tongatapu, Tonga. There is no risk of a tsunami from earthquakes at this depth.
A magnitude 7.3 earthquake occurred about 211 km (131 miles) east south-east of Neiafu, Tonga at a depth of 24.8 km (15.4 miles). There are no reports of damage or injuries. A tsunami advisory was issued and later lifted.
A very deep M6.8 occurred south of the Fiji Islands at 09:38 UTC at a depth of 628 km (390 miles). The earthquake was followed by this M7.0 earthquake at 09:51 UTC at a depth of 665 km (413 miles). Once this larger earthquake occurred, the M6.8 is considered a foreshock. This mainshock was then followed by a M6.6 aftershock at 10:14 UTC at a depth of 623 km (387 miles). The epicenters were located about 845.4 km (525.3 miles) SW of Vaini, Tonga, and 870.2 km (540.7 miles) S of Suva, Fiji. There is no risk of a tsunami from earthquakes at this depth.
A magnitude 7.6 earthquake struck southwestern Mexico on Monday, killing one person and prompting evacuations and causing buildings to sway in Mexico City. It occurred on the same day the country marks the anniversaries of two devastating quakes in 1985 and 2017 which killed thousands of people.
