First tsunami information:
Indonesian Earthquake Triggers Local Tsunami Warning (Update1)
July 5 (Bloomberg) -- A 6.7 earthquake struck off the coast of Indonesia's Sumatra island at 8:52 a.m. local time, which may trigger a tsunami that could affect some areas in the region, the Pacific Tsunami Warning Center said.
The earthquake struck near the island of Simeulue off the coast of Aceh province in Sumatra, the center said. The U.S. Geological Survey revised the magnitude from 6.8 and said the epicenter was about 30 kilometers (18.9 miles) below the sea floor and 190 kilometers west of Sibolga in Sumatra.
``Earthquakes of this size sometimes generate local tsunamis that can be destructive along coasts located within a few hundred kilometers,'' the center said in an e-mail alert sent to Bloomberg.
Sumatra has been struck by thousands of aftershocks since the magnitude-9 earthquake that triggered a tsunami across the Indian Ocean on Dec. 26. The disaster, the world's worst in 40 years, left more than 220,000 people dead or missing. Indonesia is on the Pacific Rim's ``Ring of Fire,'' a zone of active volcanoes and earthquakes.
``Tremors may be felt in the West coast Peninsular Malaysia, the Malaysian Meteorological Service said on its Web site. ``No tsumani is expected.''
The earthquake struck about 530 kilometers from Kuala Lumpur and 1,400 kilometers from Jakarta.
``We have not issued a tsunami alert because we are too far away to be affected by today's earthquake,'' said M.M.P. Mendis, a duty officer in Sri Lanka's weather office in a phone interview from Colombo. ``There is a local tsunami alert in Indonesia but we won't announce one and we are keeping an eye on the situation.''
Sri Lanka is about 3,000 kilometers from Sumatra.

I guess there are differing opinions:
"A 6.7 earthquake struck off the coast of Indonesia's Sumatra island at 8:52 a.m. local time, which may trigger a tsunami that could affect some areas in the region, the Pacific Tsunami Warning Center said."

Well... I guess they are just being cautious after December.
HOWEVER... an earthquake of 7.0 magnitude or higher would have to strike in the Pacific to issue a Tsunami Warning for the U.S. West Coast or Alaska and Hawaii. A 6.7 would not get one.
