Rename the PTWC To Be Accurate; Call It the ‘United States Tsunami Warning Center’

(This is a "two-blog" post; it’s also found today at our sister blog, CHORE – Citizens Helping Officials Respond to Emergencies.)

Yet another tsunami has killed Pacific islanders, but at least America was well informed about the status of the threat. “The system worked,” said a Hawaii Civil Defense official in praise of the Pacific Tsunami Warning Center’s network of buoys and seismographs.

Can it truly be said “the system worked” when people die? Are we so concerned about our own safety that we applaud a system that was incapable of warning unsuspecting islanders that they were in imminent danger of losing their lives?

Wanted: A Vision

How appropriate to quote Solomon in Proverbs as we look for lessons in the Solomon Islands tsunami:

“Where there is no vision, the people perish.”

What might the vision be for a tsunami warning network that actually saves lives? The current version demonstrably doesn’t do that. More than 230,000 people died in the December 2004 tsunami; at least 30 died in the Solomons, and the toll is rising.

Clearly, the way the network is put together doesn’t work if “work” is defined as being a life-saver. So let’s give the vision thing a try.

Start with a goal: An effective tsunami warning network will be structured and operated in such a way that lives will not be lost – even in a locally generated tsunami.

Apply that goal to all high-threat islands, countries and territories in the Pacific where we know with certainty killer tsunamis are generated. Analyze the existing warning capabilities – sirens, radio stations, networks. Test their reaction time.

Does the System Work?

Analyze the test results. What worked and what didn’t? Is there any possible way the existing system can warn people that a locally generated tsunami may kill them?

If not, change the system!

Argue, debate and harangue local authorities until they agree to relinquish their control of the system; holding on isn’t worth the potential loss of their citizens’ lives.

Work with the United Nations. Establish funding for system enhancements. Install a fast-alert capability that sounds sirens and scrambles radio station personnel within minutes when a threat is recognized. Set a threshold that seems reasonable – perhaps a magnitude 7.5 quake in a region that historically experiences tsunamis.

Whatever you do, NOAA, do something! The current system is not working for Pacific Islanders – so don’t call it a Pacific Tsunami Warning system.

Be honest and rename the center in Hawaii to reflect its true function. Call it the United States Tsunami Warning Center. That’s what it does well – alerts and warns the states and territories of the United States.

But don’t pretend to be a Pacific-wide life-saving tsunami warning system. Your current vision isn’t big or bold enough.

Information Still Sparse on Solomon Tsunami; Were Media Used for Time-Sensitive Warning?

News reports are short on details about the timing of the tsunami that followed the magnitude 8 earthquake in the Solomon Islands yesterday.

HONIARA, Solomon Islands (AP) -- Tsunami waves churned by an undersea earthquake crashed ashore in the Solomon Islands on Monday, wiping away entire villages and triggering alerts from Australia to Hawaii, officials said. At least 13 people were killed, and the prime minister warned that the toll would likely grow. In the South Pacific nation's west, where the devastation appeared centered, there were reports of people being swept away as waves plowed up to a half-mile inland. The magnitude-8 quake that created the tsunami was followed by more than two dozen aftershocks, including at least four of magnitude-6 or stronger.

The tsunami presumably came so quickly -- one report says only 5 minutes after the quake -- that islanders had little time to escape the waves. The questions that interest us here at Tsunami Lessons are these:

• When did islanders receive media reports – i.e., radio broadcasts – about the quake’s severity and the likelihood of a tsunami?

• Which radio outlets – local or international – carried reports of the quake, and when?


It’s one thing to issue warnings and alerts via electronic means, including email, and it’s another thing altogether to issue warnings that result in lives saved. This has been our consistent message since the onset of this blog on January 2, 2005 following the devastating Indian Ocean tsunami one week earlier.

Unless a warning can be effectively communicated by electronic news media to populations in peril, the warning has accomplishing virtually nothing.

We’ll be looking for reports from the region to learn more about the sequence of events. Here’s one of the early versions of what happened taken from an Associated Press report:

“There wasn’t any warning – the warning was the earth tremors,” Alex Lokopio, the premier of the Solomon’s Western Province, told New Zealand’s National Radio. “It shook us very, very strongly and we were frightened, and all of a sudden the sea was rising up.”

It's possible no broadcast message could have reached the island in time to warn the residents, but we don’t yet know for sure. We need to know when the first tsunami alert/warning went out from the Pacific Tsunami Warning Center and when they were recycled into the first warning broadcasts. What did radio stations in the Solomons do with the warning they presumably received?

All we have to go on is this assessment: “There wasn’t any warning….”

Tsunami Awareness Month Begins with No Jokes; New PTWC Technology Touted as Enhancement

"One goal of the improved instruments is to avoid having too many warnings, which erodes confidence in the system, McCreery said. 'The gap is really trying to keep the public prepared to do the right thing when the situation occurs.'"

That paragraph is the final one in a Honolulu Star-Bulletin story today on new instruments installed at the Pacific Tsunami Warning Center. The irony should be obvious to anyone familiar with the complete absence of a useful warning after the December 2004 Indian Ocean tsunami. (New visitors to Tsunami Lessons might want to start reading on this subject at our first post on January 2, 2005, "No Tsunami Warning -- Why?")

Tomorrow's second part of this two-part series is titled "Getting the public to respond to tsunamis" -- potentially another irony-laden angle in light of the 2004 tsunami warning failure.

Our observations are long overdue here on improvements made in NOAA's standard operating procedures to disseminate tsunami warnings using the news media -- the #1 subject we've flogged for the past two years. Enough has been written about these improvements in the past few months to conclude that NOAA has indeed restructured its early-warning procedures to engage the news media earlier than ever.

For now, we'll wait for more news during Tsunami Awareness Month to see how the PTWC actually will use its new technology to accomplish its mission -- which is to warn.
