Local media reports claim that the impact of natural disaster was also felt in the capital Jakarta.
An quake struck off the coast of Indonesia's Java island on Friday, swaying buildings as far away as the capital and prompting national authorities to urge coast dwellers to head to higher ground to avoid potential 3-meter tsunami.
"Please look for higher ground at least 10 meters (33 feet) high, stay calm and keep monitoring information from the geophysics agency", Karnawati told a news conference.
It said the epicenter was in the Sunda Strait, 65 miles from the city of Tugu Hilir in the province of Banten, on the island of Java.
"It was so scary", said Gustiani Pratiwi, who was carrying two children near an apartment block in Jakarta when she felt the quake strongly. Television footage showed workers and residents running out of high-rise buildings.
That quake triggered a massive tsunami that killed around 226,000 people along the shorelines of the Indian Ocean, including more than 126,000 in Indonesia.
Last September, a magnitude-7.5 quake and tsunami killed more than 2,000 people, leaving large swathes of Palu, on Sulawesi island, razed to the ground.
The quake alsocaused some blackouts, plunging some of the affected areas into darkness.
The quake brought back bad memories in Banten's Pandeglang region, which encompasses Unjung Kulon National Park and popular beaches, and is where a deadly tsunami struck in the dark without warning last December. His agency has also launched projects to educate people living along the coastline on how to respond to a tsunami threat, he said.
