tremblor

That first tremblor was followed by the main more destructive quake which flung him to the ground.

The strong tremblor killed 157 people and left thousands homeless.

Japanese officials are worried another devastating tremblor could happen again.

On Friday, the drill simulated the aftermath of a fictional 7.3-magnitude tremblor in central Tokyo at 7 a.m.

The disruption caused by the magnitude 7.4 tremblor has shone a spotlight on Japan's leading role in producing precision components vital for electronics and autos production when global supply chains are under COVID-19 pandemic related strain.
