NatGeo film series, Tsunami: Race Against Time, debuts Nov. 24

It’s been more than a generation since the last seriously devastating tsunami hit the Hawaiian Islands, and most residents have no memory of the threat.

We should remember—so that next time we can protect ourselves and the people for whom we are responsible.

 


 

The 1946 April Fool’s Day Aleutian quake sent a tsunami that devastated Hawaiian coastlines from Hawai’i Island to Kaua’i. The 1957 Aleutian quake’s tsunami caused significant coastal property damage in the Islands. Both destroyed homes and ran up rivers, taking out bridges. The 1960 Chilean quake's tsunami swept in from another direction. Between them, those three events killed more than 200 Hawai’i residents.

The history of the tsunamis of the Hawaiian Islands is kept by Hilo’s Pacific Tsunami Museum

Now a new series of films from National Geographic graphically reminds us of the hazard. It is a warning built on the biggest tsunami disaster in centuries—the Christmas tsunami in the Indian Ocean, which hit December 26, 2004. 

The series is Tsunami: Race Against Time.

That series of waves was generated by one of the largest quakes in recorded history, undersea off Sumatra, Indonesia. It was an unbelievably massive event, calculated at magnitude 9.1. The 1960 Chile quake was larger at 9.5, but did not cause as much death and damage.

I reviewed the film series. It contains footage you’ve never seen, and graphically describes the events that killed more than 200,000 people in Thailand, Sri Lanka, Indonesia and other islands and coastlines struck by the tsunami.

It contains first person interviews with survivors, heartbreaking stories, often with real-time imagery of those same people. It describes helplessness and heroism in the face of overwhelming conditions. And the desperate effort of Hawai’i’s tsunami scientists to warn the residents of a different ocean.

“The pure carnage of rushing water,” says one orphaned survivor, who lost his parents in the tsunami.

Among the most tragic images are of families holding each other and then torn apart by swirling gray water. Or of the clueless people who wait too long to run, or who watch until the water washes them away. Of bodies drifting in the water. And of wounded people who die in the aftermath, because the disruption was so severe that it was not possible to get medical care in time.

Most of us followed news footage of the quake and its tsunami in the final days of 2004 and early 2005. But that coverage could not provide the perspective of time. Twenty years later, survivors and rescuers and scientists provide that perspective.

Here is how the film’s producers describe their project:

“Marking 20 years since one of the deadliest natural disasters in history which spanned 14 countries, TSUNAMI: RACE AGAINST TIME provides a 360-degree view into the heart-stopping events of the 2004 Indian Ocean tsunami.

“The powerful series, from executive producers Tanya Winston and Danny Horan of multi-award-winning Blast Films and directed by Daniel Bogado, Emmy Award-winning filmmaker of Nat Geo’s ‘9/11: One Day in America,’ features personal accounts from survivors, scientists who raced against time to understand the catastrophic disaster and warn the world, journalists who broke the shocking news, and the fearless rescuers who risked their lives to save others.

“Told through harrowing video and gripping stories of survival and courage – some both seen and heard for the first time – the four-part series offers a comprehensive and immersive look at the destructive wave as it surged across the ocean, leaving a trail of devastation in its wake.”

The four-part series premieres Nov. 24 at 4 p.m. (Hawai`i time) on National Geographic and streams starting on the 25th on Disney+ and Hulu.

China fires missile into the South Pacific. Provocation? Islanders are concerned.

China just launched a nuclear-capable ballistic missile smack into the central South Pacific, without bothering to notify the target country.

What the heck could that mean?

The rocket didn’t come near Hawai’i. It was at little over 2,000 miles south. 

But that rocket flew some 7,000 miles from China to its watery landing spot. The distance from Beijing to Hawaii is just 5,000. Beijing to San Francisco is 6,000.

Was the Sept. 25, 2024, missile a message, or, as China suggests, just a routine test? Not routine, certainly, since China hasn’t done anything like this in more than 40 years.

Hawai’i folks have expressed concern about North Korean rockets gaining the capacity to fly as far as the Hawaiian archipelago, but China has long had that capacity, and it demonstrated that with the Sept. 25 launch, which reportedly terminated within the exclusive economic zone of Kiribati, near Caroline Island.

Caroline is an uninhabited atoll south of the Equator, in the Southern Line Islands. French Polynesia is to the south and east of it. The Cook Islands are to the west. U.S.-controlled Jarvis and Palmyra are to the north.

China warned the United States and Russia of the proposed launch, which is required by treaty, but did not bother notifying the target nation, Kiribati. France, New Zealand and Australia also got notice. Japan and French Polynesia did not.

China reported the missile carried a dummy warhead.

The Center for Strategic and International Studies reports that China has three models of nuclear-weapon-capable intercontinental ballistic missiles, known as Dongfeng, or East Wind. They are the DF-5, DF-31 and DF-41. Sources differed over whether the Sept. 25 missile was a DF31 or 41.

All three of the missiles have the range to reach either Hawai’i or the West Coast. The DF-5 is silo-based while the other two are transported on mobile carriers, some of which are off-road-capable.

The nation of Kiribati, which has benefitted from Chinese investment in recent years, expressed concern about the launch of a military rocket into its waters. 

French Pacific waters are just south of the rocket landing zone, and officials in Papeete also expressed concern. Radio New Zealand reports that China threw a dinner party in French Polynesia to calm the waters.

The international only news magazine The Diplomat suggested the launch was hardly “routine,” as China suggested. It was the first Chinese launch into international waters since 1980—more than four decades.

That doesn’t mean it was provocative. “Beijing’s motivation for this test launch might not have been the desire to send a political signal, but rather a need for technical data,” The Diplomat wrote.

That said, officials of numerous of the nations of the Pacific have expressed concern. China has been actively courting Pacific nations on the trade front, but until now, it has not suggested that it carries a big stick behind the open pocketbook.

Wrote The Diplomat

“China has made progress in winning over some of the Pacific Island states, but has run into resistance from others that fear turning the region into an arena of China-U.S. strategic competition. Firing a nuclear-capable missile into the midst of the islands not only stokes that fear, it positions China as an aggressor.”

As Florida cleans up from two hurricanes, Hawai`i is dodging the bullet. Instead, we get hot and dry.

 Hawai’i has benefitted in recent years from the lack of strong hurricanes, while the folks on the Atlantic coasts have taken multiple hits from big spinning storms.

Tropical storm activity can be cyclical. Sometimes it’s higher in the Atlantic; sometimes in the Pacific. That seesaw pattern has been linked to the El Nino Southern Oscillation, a climate pattern associated with ocean water temperature, air temperature, jet streams and rainfall patterns.

During El Nino events, warm water pushes into the eastern Pacific, and tropical cyclones are more likely and stronger in the Pacific. They call El Nino the warm phase. In La Nina, those waters are cooler, and the storm action moves into the Atlantic. They call it a cool phase.

Currently, we’re in a neutral period, but NOAA says we’re likely moving into another La Nina.

Back in May 2024, the National Weather Service predicted a lower-than-normal hurricane season for the Islands, anticipating that shift from neutral to a cooler phase. In a May 21, 2024 press release, NOAA reported:

“Hurricane season in the central Pacific region is likely to be below average this year,” said Matthew Rosencrans, lead seasonal hurricane forecaster at NOAA’s Climate Prediction Center, a division of NOAA’s National Weather Service (NWS). “A key factor influencing our forecast is the predicted arrival of La Nina this summer, which typically contributes to less tropical cyclone activity across the central Pacific Ocean basin.” 

So far, only Hurricanes Gilma and Hone, at the end of August, came near enough to Hawai’i to cause significant weather events locally.

Meanwhile, the Atlantic has been ravaged, pretty much as predicted.

Nine hurricanes in the Atlantic so far this year, four of them Category 4 or greater. The Eastern U.S. has been hit by two powerful and destructive cyclones in just the past month: Helene and Milton.

And the continuing transition into another La Nina does not bode well for the Atlantic coastlines.

With two months to the end of the hurricane season, Hawai’i can hold its breath with a little hope. A storm might come, but it’s less likely than average.

So what about next year? The latest NOAA El Nino forecast suggests the incoming La Nina will last into the beginning of next year. Beyond that, it’s hard to know what will happen.

But all this is playing against a background of significant climate warming. The World Meteorological Organization notes that El Nino/La Nina is not the only climate driver. It is predicting warmer temperatures over all land areas and all oceans, besides the La Nina-impacted eastern Pacific.

As you’ll see from the World Meteorological Organiation chart below, that cooler weather is south of the Hawaiian Islands. Like most of the rest of the globe, we in the Hawaiian Islands have warmer than normal weather likelihood. 

The WMO also suggests rainfall for Hawai’i will likely be lower than normal from September through November 2024. 

Hotter and drier. Welcome to the future.

Anti-disease forest fungi thrive when they can hear their neighbors: a lesson in diversity

 

There is such value in diversity.

We can take a lesson from a new bit of science that suggests that life performs better when surrounded by its community.

This study found that certain fungi grow faster—many times faster—in an environment that includes sound, even if the species itself does not make sounds.

In the soil, if you were to insert a sensitive microphone, you would pick up the rustle of ants, the scuffling of scurrying beetles, the whisper of larvae, the swooshing of earthworms on their liquid missions and the motion of all the other critters that normally occupy a healthy underground environment.

Fungi don’t have ears, but from this study, clearly they can sense the presence of other creatures by the impacts of their movements, and you could anthropomorphize that they appreciate the company. They certainly behave as if they do.

This particular study was published in the journal Biology Letters. It was reviewed in the New York Times here. 

Wrote Times writer Veronique Greenwood: “Playing sound to Trichoderma harzianum, a green microscopic fungus that defends tree roots from pathogens, led to growth rates seven times as fast as those of fungus grown in the sound of silence. If the laboratory findings can be replicated in nature, then sound could be an unexpected new tool for improving the health of forests, encouraging beneficial microbes to take root and thrive.”

In this case, the researchers just played white noise for the green fungi, and saw dramatic increases in growth compared to the fungi grown in silence.

And here’s a leap.

A totally other piece of science, from the 13 September 2024 issue of Science magazine, expressed concern that the survival of Asian forest trees that contain anti-cancer properties is threatened. People are going into the forest and harvesting the trees to rarity and endangered status.

“Without these trees, cancer patients will lose access to a vital treatment,” wrote authors Gao Chen, Xiang-Hai Cai, Jia Tang, Guillaume Chomicki and Susanne Renner.

In Hawai’i, we have seen the impacts of loss of diversity. If you lose a pollinating bird species, you risk losing the plants they pollinate, and then the insect and fungal communities that rely on those plants. Round and round it goes.

Back to the fungus study, researchers aren’t sure how the fungi are sensing the sound.

“The mechanism responsible for this phenomenon may be fungal mechanoreceptor stimulation and/or potentially a piezoelectric effect; however, further research is required to confirm this hypothesis,” wrote authors Jake M. Robinson, Amy Annells, Christian Cando-Dumancela and Martin F. Breed.

But it was clear that in the presence of sound—all other things being equal—this little green fungus, Trichoderma harzianum, produces lots more biomass and also produces more spores, than in silence.

And they give back to their forest community. These little life forms colonize tree roots, and then protect the trees from disease and rot-causing fungi. They’re so good at it that they’re used as a natural fungicide—applied to leaves, seeds and the soil around valued plants.

Nature’s message is that a diverse community is a far healthier, more productive one.

Navy: Targeting Ka'ula Island bird refuge weekly with bombs and guns would only result in "incidental" take

 The Navy’s new proposal to expand bombing and gunnery practice at Ka’ula Island seems insupportable, both morally and as a matter of federal law.

Here is the Draft Environmental Assessment that includes the Ka’ula impacts.

It expands potential military operations at the tiny island to 55 per year, more than one a week. That is on an island that is a designated state seabird sanctuary (established 1978) and contains endangered and state and federally protected plants and birds, and marine protected species in the nearshore waters.

Ka’ula is one of the four islands of of Kaua’i County (Kaua’i, Ni’ihau, Lehua and Ka’ula). The designated weaponry impact area is 11 acres at the southern end of the 130-acre island.

Ka’ula is well known in Hawaiian history and chant. The bird life there was once so dense that the island was used as an example of overcrowding. 

(Hā’iki Ka’ula I ka ho’okē a na manu. There is no room on Ka’ula, for the birds are crowding. –from ‘Ōlelo No’eau by Mary Pukui.)

It has been bombed since 1952.

The Navy over the years has steadfastly resisted calls to end its bombing, from fishermen, from U.S. Congress members, the U.S. Secretary of the Interior, from the Kaua’i County Board of Supervisors (1961) and Kaua’i County Council (1975), and from federal fisheries and wildlife officials.

And from the State of Hawai’i, whose attorney general in 1978 asserted the island belongs to the state. That conflict over ownership was not resolved, and state officials now say the ownership is contested but no recent efforts to assert state control have been reported.

Weapon strikes are proposed to be limited to the designated 11-acre “impact area.” But that has not always been the case: 1) A 1978 fisherman’s report saw bombs exploding both in the water and among seabirds; 2) The Draft EA says there are likely live munitions on the island outside the impact area; 3) On one occasion in 1965, bombs intended for Ka’ula landed on Ni’ihau, more than 20 miles away.

The new proposal says only inert weapons will be deployed in the future.

The birds and seals of Ka’ula, as well as passing whales and dolphins, are protected by the US. Migratory Bird Treaty Act, the U.S. Marine Mammal Protection Act as well as the island’s designation as a State of Hawai’i bird refuge.

The Draft EA proposes that the impact of bombing, gunnery exercises, helicopter landings and other activities are acceptable. There are Hawaiian cultural sites, including stone temples and habitation sites, but they are outside the designated impact zones and so, “impacts on cultural resources would be less than significant.” (Page 3-86)

The Navy’s legal justification for harming wildlife is contained in a federal law, the 2003 National Defense Authorization Act. It “gave the Secretary of the Interior authority to prescribe regulations to exempt the Armed Forces from the incidental taking of migratory birds during authorized military readiness activities,” the Draft EA says.

Based on that, the Draft EA argues that targeting a wildlife refuge and protected bird nesting site with bombs, shells and landing helicopters would result in takes that are merely incidental. The Draft EA says (Page 3-30) that the Department of Defense has a responsibility to minimize and mitigate its impacts. But it seems at least problematic to argue incidental and minimized when the wildlife refuge is the target.

The Draft EA argues that health, safety and noise are not issues because there are “no human sensitive receptors” nearby. This, of course, does not address the impacts on the health, safety or hearing of protected sooty terns, threatened black-footed albatross or endangered Hawaiian monk seals.

The Navy asserts that it owns Ka’ula. That position has long been challenged by Hawai’i.

The island was set aside by the Territory of Hawaii for use by the U.S. Department of Commerce under the U.S. Lighthouse Service in 1924 as a lighthouse reserve. Commerce conveyed it to the Coast Guard, which operated a navigational light there until 1947, when it was permanently shut down.

Instead of returning the island to the territory, the Coast Guard in 1952 authorized the Navy to conduct bombing exercises, apparently without the authorization of territory. 

Kaua’i County residents began regularly protesting the activity within a few years, at the behest of anglers who said the bombing was impacting birds, which the fishermen depended on to locate schooling fish.

U.S. Rep. Patsy Mink in the early 1960s urged the island’s inclusion in the Hawaiian Islands National Wildlife Refuge, and the Department of Interior started but failed to complete that inclusion.

The Navy rejected the Hawaiian ownership arguments, and in 1965, U.S. Rep. Spark Matsunaga reported that the Coast Guard had transferred its authority over the island to the Navy.
