The US Geological Survey said it was 6.0-magnitude earthquake, occurring at a depth of 43 kilometers offshore the western part of Java island. There are no reports of casualties or serious damage (yet). There was also no threat of a tsunami.

Still, it was a scary happening with buildings shaking heavily for about 30 seconds.

Indonesia's Metereology, Climatology and Geophysics Agency (BMKG) said it was a 6.4 magnitude earthquake that struck off the coast of West Java, with its epicenter in the Indian Ocean, 81 kilometers southwest of Lebak (Banten), at a depth of ten kilometers.

Due to the movements of major tectonic plates and volcanic activity in the region, Indonesia is regularly hit by earthquakes. In December 2017 a 6.5-magnitude earthquake caused three deaths on Java.

According to research conducted by the World Bank, natural disasters - including earthquakes - cost Indonesia about 0.3 percent of gross domestic product (GDP) on an annual basis. In a 2015 report on disaster risk management prepared by the Indonesian government it was mentioned that a major earthquake, occurring once every 250 years, could cause losses in excess of USD $30 billion, or 3 percent of GDP.
