Introduction: Indonesia experienced a powerful earthquake with a magnitude of 6.5 on Saturday night, originating in West Java province. Despite the significant intensity of the quake, no tsunami alert was issued, and initial reports suggest minimal damage and no casualties.
Epicenter and Timing: The earthquake occurred at 23:29 Jakarta time (1629 GMT) on Saturday, with its epicenter located 151 km southwest of Garut Regency. The depth of the earthquake was recorded at 10 km, indicating a relatively shallow focus.
Impact and Effects: The tremors of the earthquake were felt across a wide area, including in Jakarta, the capital of Indonesia, and the nearby province of Banten. Reports indicate that high-rise buildings swayed for about a minute in Jakarta, while strong shaking was experienced in two-story homes in Bandung, the capital of West Java province, as well as in surrounding cities like Depok, Tangerang, Bogor, and Bekasi.
Intensity and Areas Affected: According to the country’s meteorology, climatology, and geophysics agency, the intensity of the quake was felt at IV MMI (Modified Mercalli Intensity) in Sukabumi town and Tasikmalaya town, and III to IV MMI in Bandung city. This indicates that the shaking was felt strongly in these areas, potentially causing minor damage to buildings and infrastructure.
Tsunami Alert and Safety Measures: Despite the significant magnitude of the earthquake, no tsunami alert was issued by the agency. This decision was based on the assessment that the tremors were not expected to generate giant waves that could pose a threat to coastal areas.
Conclusion: The earthquake in West Java province serves as a reminder of Indonesia’s vulnerability to seismic activity due to its location along the Pacific Ring of Fire. While the impact of this earthquake appears to be relatively minor, it underscores the importance of preparedness and safety measures in earthquake-prone regions.
