The 5.1 magnitude tremor struck in Kangin, Indonesia, soon after 2.15pm, and was felt inland. This was 130 miles off the coast of the holiday hotspot island. It follows another 5.1 magnitude tremor that stuck at 2.20pm UK time on neighbouring island Java. Currently no tsunami warning has been issued.
The earthquake hit at a depth of six miles.
It is not yet known if there were any casualties or serious damage.
Bali sits on the Ring of Fire, a hotbed of seismic activity where 81 percent of the world’s earthquakes occur.
Volcanic eruptions and earthquakes occur regularly along the ring.
This is because it is the major fault line where the majority of the world’s earthquakes occur.
The capacity of the Indonesian emergency and rescue services to deal with large natural disasters is limited.
Indonesia is an island archipelago made up of more than 17,000 volcanic islands so is a frequent target of the Ring of Fire.
The Ring of Fire is a huge horseshoe-shaped ring that goes around the Pacific basin.
It is made up of a string of volcanoes and seismic activity.
The Ring of Fire was formed after the earth’s oceanic plates and continental plates interacting.
Indonesia has suffered a number of serious earthquakes over the last year.
On 28 September 2018, a 7.4 magnitude earthquake and tsunami hit Central Sulawesi on 28 September 2018, affecting the Donggala, Palu, Sigi and Parigi Moutong regions and causing significant loss of life, casualties and widespread damage.
Earlier in the same year in July and August 2018, the north-east of the island of Lombok experienced a series of significant earthquakes that were followed by many aftershocks in the same area.
The earthquakes killed more than 500 people and caused significant damage to buildings and infrastructure in north and west Lombok.
