The 2017 Java earthquake occurred on 15 December 2017 when a moment magnitude 6.5 earthquake struck the Indonesian island of Java, specifically the city of Tasikmalaya on 23:47:58 West Indonesian Time (16:47:58 UTC) in West Java, Indonesia. The earthquake struck at a depth of 91 km and was categorized as a strong but deep earthquake.[2] It was initially registered as a 7.3 magnitude earthquake by Indonesian agencies. Widespread damages have been reported across Tasikmalaya, the nearest major city to the epicentre. A tsunami warning was immediately issued by the authorities but was subsequently cancelled.[3] Three people have been confirmed dead.[4]

Earthquake

The earthquake struck with a moment magnitude of 6.5 Mw near Tasikmalaya, West Java at 23:47 local time. The epicentre was reportedly located 11 km from Tasikmalaya. Strong shaking were widely reported across West Java, Central Java, Banten, Yogyakarta and Jakarta. Hundreds of people rushed out from high rise buildings in the capital Jakarta.[1] People in Yogyakarta also reported strong shaking during the earthquake.[1] In Bali the earthquake was registered as a light shaking in the Mercalli intensity scale. Strong shaking was also reported in Mataram, West Nusa Tenggara. The earthquake struck at 23:47, meaning that most residents were sleeping during the earthquake.

The earthquake was initially registered as a 7.3 Mw and prompted a tsunami warning due to its intensity.[5] Confusion and panic immediately ensued and sounds of horns were heard everywhere as streets were jammed.[6] People who were living in the coastal area were told to evacuate to high grounds. Tsunami warnings and advisory were in effect in several locations in Java, particularly in Tasikmalaya and Pangandaran. The Indonesian Agency for Meteorology, Climatology and Geophysics stated that tsunami warnings were issued in Ciamis and Tasikmalaya.[7] Tsunami advisories were in effect in the following regencies and cities in Java: Bantul, Kulonprogo, Cianjur (Sindangbarang), Garut, Sukabumi (Ujung-Genteng), Cilacap, Kebumen.[7]

Rise in water level has been reported in Tasikmalaya. However, Indonesian official later confirmed that there was no tsunami. The warning was subsequently cancelled on 02.26 WIB.[8] Authorities later advised people to return to their homes.[9]

A municipal hospital was damaged in Banyumas,[10] while a man was killed in Ciamis as his house collapsed due to the earthquake. An elderly woman was killed in a house collapse.[11] Another injury was reported in Kebumen after a house collapsed.
