SEA LEVEL READINGS INDICATE A SMALL TSUNAMI WAS GENERATED. IT MAY
HAVE BEEN DESTRUCTIVE ALONG COASTS NEAR THE EARTHQUAKE EPICENTER.
FOR THOSE AREAS - WHEN DAMAGING WAVES HAVE NOT OCCURRED FOR AT
LEAST TWO HOURS THEN LOCAL AUTHORITIES CAN ASSUME THE THREAT IS
PASSED. DANGER TO BOATS AND COASTAL STRUCTURES CAN CONTINUE FOR
SEVERAL HOURS DUE TO RAPID CURRENTS. AS LOCAL CONDITIONS CAN
CAUSE A WIDE VARIATION IN TSUNAMI WAVE ACTION THE ALL CLEAR
DETERMINATION MUST BE MADE BY LOCAL AUTHORITIES.
NO TSUNAMI THREAT EXISTS FOR OTHER COASTAL AREAS IN THE INDIAN
OCEAN ALTHOUGH SOME OTHER AREAS MAY EXPERIENCE SMALL SEA LEVEL
CHANGES AND STRONG OR UNUSUAL COASTAL CURRENTS.

THIS WILL BE THE FINAL BULLETIN ISSUED BY THE PACIFIC TSUNAMI

BECOMES AVAILABLE.

THE JAPAN METEOROLOGICAL AGENCY MAY ISSUE ADDITIONAL INFORMATION
FOR THIS EVENT. IN THE CASE OF CONFLICTING INFORMATION...THE
MORE CONSERVATIVE INFORMATION SHOULD BE USED FOR SAFETY.

There seems to be a lot of earthquakes all of a sudden.

A question: The area is volcanically active. Can this be indication of an eruption of any of its many volcanos, namely Tambora or Toba?

It may signal something yet to come, lurker.

Those poor people in Indonesia! They can't catch a break. That was a monster sized quake and aftershock.

Every 200 years, Indonesia is more seismically active. The 1800s had Tambora (1815) and Krakatoa (1883). Tambora is the biggest eruption in recent history. Much larger and more dust than Krakatoa.

Unfortunately, Indonesia lies along the Ring of Fire.

That area is also home to a super Volcano . I wonder if all this activity could hasten an eruption???

Toba or officially, Lake Toba, is the supervolcano. I think the earthquakes have been in that area, but I don't have earthquake data to pinpoint if it is close to Lake Toba.

The Tambora eruption of 1815 led to the "Year without a Summer" in Europe and North America in 1816.
