15:44 UTC UPDATE : INDONESIAN GOVERNMENT LIFTS TSUNAMI ALARM.

NOAA Tsunami bulletin EVALUATION

 A DESTRUCTIVE WIDESPREAD TSUNAMI THREAT DOES NOT EXIST BASED ON
 HISTORICAL EARTHQUAKE AND TSUNAMI DATA.

 HOWEVER - THERE IS THE POSSIBILITY OF A LOCAL TSUNAMI THAT
 COULD AFFECT COASTS LOCATED USUALLY NO MORE THAN A HUNDRED
 KILOMETERS FROM THE EARTHQUAKE EPICENTER. AUTHORITIES FOR THE
 REGION NEAR THE EPICENTER SHOULD BE AWARE OF THIS POSSIBILITY.
 AREAS FURTHER FROM THE EPICENTER COULD EXPERIENCE SMALL SEA
 LEVEL CHANGES AND STRONG OR UNUSUAL COASTAL CURRENTS.

ESTIMATED INITIAL TSUNAMI WAVE ARRIVAL TIMES AT FORECAST POINTS
WITHIN THE WARNING AND WATCH AREAS ARE GIVEN BELOW. ACTUAL
ARRIVAL TIMES MAY DIFFER AND THE INITIAL WAVE MAY NOT BE THE
LARGEST. A TSUNAMI IS A SERIES OF WAVES AND THE TIME BETWEEN
SUCCESSIVE WAVES CAN BE FIVE MINUTES TO ONE HOUR.
