FYI, there has been a 7.1 earthquake north of Bali here in Indonesia. The quake happened in deep ocean. No, I did not feel it.

Tectonic Summary

The 515-km-deep August 28, 2023, M 7.1 earthquake north of the Bali and Lombok islands, Indonesia, occurred due to normal faulting within the deeper (>500 km depth) portion of the Java arc subduction zone. The earthquake occurred where the Australia plate subducts northward beneath the Sunda plate. At the location of the earthquake, the Australia plate moves approximately northward with respect to the Sunda plate at a rate of 73 mm/yr. Trench parallel normal faulting earthquakes are commonly observed near the base of the subducting slab.

Earthquakes with focal depths greater than 300 km are called "deep-focus" earthquakes. Deep-focus earthquakes cause less damage on the ground surface above their foci than similar-magnitude shallow-focus earthquakes. Still, large deep-focus earthquakes may be felt at great distances from their epicenters.

Within the past century, six earthquakes of M6.5 or larger have occurred within 250 km of the August 28, 2023, earthquake. The closest earthquake was a 510-km-deep March 10, 2011, M 6.5 event approximately 20 km from this event.
