It looks like USGS has already downgraded the magnitude to 6.9. That's still a very large quake.

is there still a tsunami warning?
The small 3.5-km-wide island of Tinakula is the exposed summit of a massive stratovolcano that rises 3-4 km from the sea floor at the NW end of the Santa Cruz islands.
Tinakula resembles Stromboli volcano in containing a breached summit crater that extends from the 851-m-high summit to below sea level.
Landslides enlarged this scarp in 1965, creating an embayment on the NW coast.
The satellitic cone of Mendana is located on the SE side.
The dominantly andesitic Tinakula volcano has frequently been observed in eruption since the era of Spanish exploration began in 1595.
In about 1840, an explosive eruption apparently produced pyroclastic flows that swept all sides of the island, killing its inhabitants.
Frequent historical eruptions have originated from a cone constructed within the large breached crater.
These have left the upper flanks of the volcano and the steep apron of lava flows and volcaniclastic debris within the breach unvegetated.
