Indonesia's Meteorology, Climatology, and Geophysical Agency reported a magnitude 4.9 quake in Indonesia near Sewon, Yogyakarta, only 12 minutes ago. The earthquake hit early morning on Wednesday 24 February 2021 at 6:18 am local time at a shallow depth of 10 km. The exact magnitude, epicenter, and depth of the quake might be revised within the next few hours or minutes as seismologists review data and refine their calculations, or as other agencies issue their report.
Based on the preliminary seismic data, the quake should not have caused any significant damage, but was probably felt by many people as light vibration in the area of the epicenter.
Weak shaking might have been felt in Bambanglipuro (pop. 44,700) located 90 km from the epicenter, Pundong (pop. 24,100) 90 km away, Srandakan (pop. 29,500) 91 km away, Pandak (pop. 56,000) 94 km away, Bantul (pop. 58,700) 97 km away, Sewon (pop. 73,600) 99 km away, Kasihan (pop. 86,200) 104 km away, and Yogyakarta (pop. 636,700) 107 km away.
