Bali - The meteorology, climatology and geophysical agency in Indonesia said there's no risk of a tsunami, but it's important to be aware of the potential for aftershocks to happen.

The earthquake's preliminary magnitude was 7.4, but there's usually a big difference between the first one and the second. There were then aftershocks with a magnitude of 5.4-5.6 that went out just before dawn in Bali Sea. People in eastern Java, central Java, western nusa tenggara and eastern Nusa tenggara felt the earthquake and panicked as buildings shuddered for a few seconds.

People rushed to get to higher ground after hearing about the powerful shaking, but things calmed down after they got texts saying the earthquake had no effect on a tsunami. One Australian tourist said they thought the walls would come down on their hotel.

An Australian tourist reported on social media that the shaking was so severe that they thought the walls of their hotel would collapse. Residents of the neighbouring provinces of eastern Java, central Java, western nusa tenggara and eastern Nusa tenggara also reported feeling the shaking and experiencing panic as their homes and buildings swayed for a few seconds.

The magnitude of the earthquake was estimated to be 5.6, resulting in the death of 331 people and the injury of nearly 600 in the western city of Cianjur. This was the most serious disaster to hit Indonesia since a 2018 earthquake and tsunami in the island of Sulawesi claimed the lives of more than 2,340 people.

Indonesia is a large archipelago with 270 million people, and is prone to natural disasters due to its location on the so-called 'Ring of Fire', an arc of volcanic eruptions and faultlines in the Pacific Ocean. In 2004, an earthquake in the Indian Ocean triggered a devastating tsunami, resulting in the deaths of over 2,300 people, mostly in Aceh province.
