M4.9 Earthquake near Mid-Indian Ridge — April 19, 2026
2026-04-19 08:07:34 UTC (10 hours ago)
Aftershock of the M5.5 mainshock.
On April 19, 2026 at 08:07 UTC, a magnitude 4.9 shallow crustal earthquake struck near Mid-Indian Ridge, at a depth of 10.0 km and coordinates -21.7318°, 68.8140°. This earthquake was detected by 34 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 369, placing it among routine seismic activity.
This earthquake is part of an ongoing aftershock sequence following the magnitude 5.5 mainshock that occurred 15 days ago near Mid-Indian Ridge. Since the mainshock, the USGS has recorded 4 aftershocks in this area. Aftershock activity is expected to continue for days to weeks as stresses on surrounding faults redistribute.

How strong was the magnitude 4.9 earthquake near Mid-Indian Ridge?
The magnitude 4.9 earthquake that struck near Mid-Indian Ridge on April 19, 2026 at 08:07 UTC had a depth of 10.0 km. For context, this was a light earthquake commonly felt near the epicenter.
Where did the earthquake occur?
The earthquake epicenter was located at -21.7318°, 68.8140°, which is near Mid-Indian Ridge.
Were there aftershocks?
Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 4.9 earthquakes can continue for several days and gradually diminish over time.
Is this the same earthquake as the M5.5 one earlier?
No. This magnitude 4.9 earthquake is an aftershock of the larger magnitude 5.5 mainshock that occurred earlier near Mid-Indian Ridge. Aftershocks are smaller earthquakes triggered by stress changes from the mainshock.
What should I do after an earthquake?
If you were in the affected area: check yourself and others for injuries, inspect your home for damage, and be prepared for aftershocks. For detailed guidance, see our earthquake safety guide and emergency planning resources.
