“Our data goes back 10 years, and no earthquakes measuring a magnitude of 4.2 or higher have been detected within 300 km (186 mi) of this epicentre.”
The organisation said the centre of this earthquake had a “very shallow depth of 10 kilometres”, and shallow earthquakes usually have a larger impact compared to earthquakes deep in the earth.
While residents have reported feeling the ground shaking, there have been no reports of damage or injuries resulting from either event.
Most tsunamis are triggered by earthquakes that originate directly under or close to the sea. However, there were no tsunami warnings.
