Moderate earthquake of magnitude 4.9 just reported 120 km southwest of Bandar Lampung, Indonesia

4.9 quake 12 Jul 9:52 am (GMT +7)
The United States Geological Survey reported a magnitude 4.9 quake in Indonesia near Bandar Lampung, Lampung, only 20 minutes ago. The earthquake hit in the morning on Tuesday, July 12th, 2022, at 9:52 am local time at a moderately shallow depth of 35 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.
A second report was later issued by the citizen-seismograph network of RaspberryShake, which listed it as a magnitude 4.9 earthquake as well. Other agencies reporting the same quake include the German Research Centre for Geosciences (GFZ) at magnitude 5.0, and the European-Mediterranean Seismological Centre (EMSC) at magnitude 4.9.
Towns or cities near the epicenter where the quake might have been felt as very weak shaking include Bandar Lampung (pop. 800,300) located 120 km from the epicenter.

please share your experience and submit a short "I felt it" report! Other users would love to hear about it!
If you did NOT feel the quake although you were in the area,
please report it! Your contribution is valuable to earthquake science, seismic hazard analysis and mitigation efforts. You can use your device location or the map to indicate where you were during the earthquake. Thank you!
Aftershocks
[More info]
Based on its magnitude, the fault that was active during the quake ruptured along a surface of approx. 13 km
2 (=5 sqare miles) as a first-order estimate. The length of the rupture zone thus was probably around 6 km (4 mi).
Aftershocks typically occur during the days and weeks following the quake at or near the same fault, at distances of up to approx. two times the length of the rupture zone.
The often broadly linear arrangement of aftershock epicenters encompasses the rupture zone of the main shock (check on the
map below to verify).
Recorded aftershocks, latest first (0 quake)
So far, no aftershocks have been registered.
