Japan Observes Tiny Tsunami After 6.7 Magnitude Quake
On Sunday evening, Japan reported tiny tsunami waves hitting its northern Pacific coast following an offshore earthquake measuring 6.7 magnitude.
Tsunami Details
- The first tsunami reached Miyako, Iwate, at 5:37 pm (4:37 pm Singapore time), but it was too small for the Japan Meteorological Agency (JMA) to measure its size.
- Two minutes later, a 10cm wave arrived at Ofunato, according to the JMA.
Earthquake and Warnings
The earthquake struck around 5:03 pm off the coast of Iwate. The JMA issued a tsunami advisory warning waves could reach up to 1 meter high.
The US Geological Survey recorded the quake at magnitude 6.8.
"A tsunami advisory has been issued" for the Iwate coast, the JMA said in a bulletin, warning that waves could approach at any moment.
Aftershocks and Regional Activity
Following the main quake, aftershocks ranged from magnitude 5.3 to 6.3, the JMA reported.
Earlier that day, the same region experienced six offshore quakes between magnitudes 4.8 and 5.8, which were barely felt on land and did not trigger tsunami alerts.
Historical Context
The region still remembers the devastating 9.0 magnitude undersea earthquake in 2011 that caused a tsunami resulting in about 18,500 deaths or missing persons.
Observation
Live Japanese television showed calm seas during the events.
"The region is haunted by the memory of a massive 9.0-magnitude undersea quake in 2011, which triggered a tsunami that left around 18,500 people dead or missing."
