Japanese officials have lifted the tsunami warning they issued for the nation's Pacific coastline after strong earthquakes struck the Kuril Islands northeast of Japan earlier Wednesday.
Earthquake monitoring agencies recorded a quake with a magnitude of at least 7.8 followed by three tremors with magnitudes of 6 or higher.
Japanese officials advised people in Pacific coastal areas to flee to higher ground, but only minimal waves were reported in northern Japan.
The Japanese Meteorological agency warns other waves still could follow and urged continued caution.
Strong earthquakes have the potential to generate a destructive wave that can strike coastlines near the epicenter within minutes of the quake.
