A powerful earthquake registered by the USGS as M6.9 struck off the coast of southwest Sumatra, Indonesia at 12:03 UTC on Aug 2. The agency is reporting a depth of 52.8 km (32.8 miles).
The epicenter was located 102 km (63.4 miles) WSW of Tugu Hilir, Indonesia.
There are approximately 40,000 people living within 100 km (62 miles).
Some 40 million people are estimated to have felt the shaking.
An early tsunami warning was issued (at 12:03 UTC) but was soon ended after no discernible change to the sea-level was observed.
There have been no reports of fatalities or major damage.
In addition, nearby volcanoes, particularly Sangeang Api, have been very active of late.
Seismic and Volcanic activity has been correlated to changes in our sun.
The recent global uptick in earthquakes and volcanic eruptions is likely attributed to the drop-off in solar activity, coronal holes, a waning magnetosphere, and the influx of Cosmic Rays penetrating silica-rich magma.
