The epicenter was located about 1 423 km (884 miles) south of Little Grove, and 1 759 km (1 093 miles) south of Perth, Western Australia.
There is no tsunami threat from this earthquake.
The USGS has issued a Green alert for shaking-related fatalities and economic losses. There is a low likelihood of casualties and damage.
The quake was followed by M4.8 at 02:31 UTC and M5.2 at 04:56 UTC, both on June 8.
This region is situated in the remote southern Indian Ocean and is characterized by submarine ridges forming part of the boundary between the Indo-Australian and Antarctic tectonic plates. No major islands or populated landmasses are situated nearby, and the area is far from inhabited territories.
Tectonically, the Indian-Antarctic Ridge is an active spreading center where the Indo-Australian and Antarctic plates diverge, resulting in frequent moderate to strong seismic activity along the submarine ridge.
