Tern-niversary / by Michael Johns

Today is the 5-year anniversary of the great microburst of 2012, a brief yet destructive meteorological phenomenon that effectively put an end to a remote long-term seabird monitoring camp on Tern Island in French Frigate Shoals. This event also prematurely ended my scheduled six month deployment as a field tech on this tiny island in the middle of the Pacific. I wrote about my experience of the great storm back in 2012, and decided to repost the old blog here. The following is my account of that day, along with some grammatical fixes and updated photos.

Sunday December 9th, 4:30 AM:

I awoke as I always did around 4:30 in the morning to start the day. It was muggy and warm when I went to bed so I left my windows open to get some breeze. It had apparently rained throughout the night, slightly flooding my room. I normally got up this early to use the unlimited download time we were given for the internet (from midnight to 6am), but it had been down the night before, and I wasn’t sure if I wanted to bother getting out of bed to test it. But the lightning outside was pretty cool, and a cup of coffee sounded really good, so I got up anyway. The lightning was indeed amazing; it was like storms I had seen visiting my brother in Alabama, the sky lit up like a dying light bulb blinking every few seconds. It kept going, never really producing any bolts, it just lit the clouds a brilliant purple hue. Although it was raining steadily, the direction the rain was falling kept the water off the porch, so I sat outside with my coffee in the warm morning air and photographed the lightning show. The wind was coming from the south, so I stayed relatively dry sitting in the lee of the building.

5:45 AM:

After watching the weather for a while, trying to catch the occasional lightning bolt, the wind abruptly swung from the south to the north, driving the rain straight onto the porch. At first it was tolerable, but then the rain grew heavier, getting me and my camera gear wet. I immediately took my tripod down and went back inside, and as I shut the front door to keep the rain out I noticed that the temperature had rapidly dropped at least ten degrees, like I was standing in front of an open freezer door. It got so cold I almost felt I could see my breath. I didn’t think much of it. I figured the cold front had just passed over us, explaining the shift in the wind and the sudden increase in rain.  Although this had never happened before, so I thought it noteworthy. In the meantime the lighting intensified, it was now producing proper bolts and very loud thunder, the storm was right on top of us. With nothing else to do I sat down at my computer in the radio room and gave the internet a shot. Amazingly, it worked enough for me to send an email out to Casey, bragging about how cool the lightning was and how monstrous the surf sounded.

Sometime around 6:00 AM:

I had just sent Casey an email, and was sitting at my computer thinking what I was going to write about the storm (I usually wrote up or edited a journal entry in the morning), when out of the blue the VHF radio on a shelf behind me started producing static, like the sound an analog TV makes when it’s not receiving a signal. I had never heard it do this before, I wasn't even aware the radio was on, so it startled me. With this and the extremely cold air minutes earlier, I began to worry that something was off. Then the sky just opened up and dumped the heaviest rain I had ever heard, as if the building was sitting beneath a massive waterfall. The radio kept chattering and the rest happened so fast it’s hard to describe. Like a shockwave the pressure in room grew so strong my ears started popping, and I began hearing a faint rumbling sound that swiftly grew louder. This was immediately followed by a swift blast of cold wind to the face, as if someone had just kicked open the emergency exit of a plane in mid flight. Books from the shelf behind me and pieces of debris started flying about the room, and I instinctively dove under the computer desk and covered my face. At this point the rumbling was all around me. It sounded like metal and wood were being run through a blender, lots of banging, cracking and screeching. It was the most violent sound I had ever heard. I had visions of the movie Twister playing in my head, dairy cows levitating and all, but I had no idea was going on and I thought for sure the whole building was falling down. I wondered if the Mayans had been right all along, the world was coming to an end (This was 2012 after all). I figured I was going to be buried in a pile of rubble when it was all over. The chaos lasted for about 5 seconds and then stopped. The rain, the wind, everything was calm again. I stayed under the desk, not knowing what was going on. Then I heard Morgan say from the hall, “where’s Mike?”, and at that point I got my first glimpse of the extent of the damage. Initially, I was shocked to see one of the interior walls and the door to the radio room had been knocked down, and the place was littered with soggy books and sheets of data.

Then I saw the common room. It was just after six now, still too early for the sun, and the whole building was dark. The lightning flashed and revealed all the walls were gone. It was such an eerie sight. Every time the lighting went off, where the entertainment center stood, the bookshelves, the chalkboard with our daily schedule, it was all just an open view of a tumultuous sea and a nasty sky. The wind was blowing salt spray and rain right through our dining area, chairs were strewn about the room, and the kitchen was covered with knives, pots and pans – it was a mess. The wind had been so strong it moved stoves in the kitchen, and blew a heavy freezer full of old video tapes clear through a wall and out the building. We had just rearranged the movie area, and set up the Christmas tree for the holidays, and it was now a massive pile of junk. Broken glass, bad novels, random debris had been blown out with the east walls, landing in a fan outside on top of albatrosses incubating eggs. The entire scene was a disaster.

Four rooms, including mine, had been completely blown out. It was a jungle of shattered drywall and mangled aluminum framing that had been ripped from their foundations. Fortunately I wasn’t in my room, and all other occupied rooms only received minor damage. The west end of the hallway was so mangled the last three rooms were inaccessible. One unused bed was buried under three different walls. If anyone had been sleeping there they would have been crushed. We really lucked out.

The damage was extensive. The boathouse looked like a bomb had gone off, the tractor shed had gaping holes in its concrete walls, there were many leaks in the plumbing, the solar panels were torn from the braces, radio antennas were stripped off the roof, six bedrooms, one office, two bathrooms, the laundry room, and all of the common room had their exterior walls blown out, and a few other structures including fuel storage units and a couple fiberglass boat hulls were scattered around the west portion of the island. We took a big hit, and it was all a major shock to witness.

Even more disturbing was searching for injured and buried birds. I can’t imagine what it must have been like for rescue workers on scene at the World Trade Centers or in Japan after the tsunami. It was very difficult seeing albatrosses, birds that I have been admiring for years, with broken wings and bloody necks stuck beneath sheets of wall panels. Some were killed instantly by projectiles, others were flattened on their nests, and many were simply limping around with mangled wings. Since the debris from our buildings had inflected the most damage to the wildlife, it was our responsibility to euthanize the suffering birds. Something I hope to never have to do again. The death count is as follows: 62 Brown Noddies, 97 Black Noddies, 10 White Terns, 17 Red-footed Boobies, 6 Great Frigatebirds, 1 Pacific Plover, 24 Laysan Albatross, and 22 Black-footed Albatross, for a total of 239 birds of which 79 were banded.

It’s amazing how selective these storms can be. You always hear stories about how tornados will completely disintegrate one home, and leave another only feet away untouched. The microburst we experienced only affected the west end of the island where all of our facilities stood. The east end of the island showed no signs of damage. It appeared every leaf and branch hadn’t even been rustled. The wind apparently stopped at the warehouse to the east, and was most intense near the boathouse to the west. As much as I can gather from Wikipedia, a microburst forms by the rapid evaporation of highly saturated air in a thunder head. As the mass of air evaporates, it cools. The sudden cooling forces the air mass to descend from the cloud, accelerating as it falls through the wet air below. When the air mass eventually collides with the ground it can reach speeds of 150 mph, leveling anything that stands in its way. At least that’s what I think happens. Either way the point is it gets very windy very fast, and causes intense localized destruction.

The storm carried on for three days. It was difficult to sleep the first night after the disaster. No longer did we trust the integrity of the building. We were convinced that the next big gust could blow the whole place down. The rooms in the north wing where we moved all of our valuables and beds were mostly intact, although the roofing had been compromised and new leaks had sprung open.  We were able to recover most of the archived data, although some had been saturated, and luckily all of our expensive computers and camera gear survived. My computer was covered in dirt and debris and had a desk lamp fall on the keyboard, but it still worked. We boarded up the kitchen and the exposed hallway, and somehow managed to recover the internet, although its functionality was limited. The solar panels were damaged, but remained intact enough to still charge the battery bank. Chad fixed the broken pipes in the plumbing and shunted all water to the north hall. We limped along for 10 days. In the meantime we piled all the wooden debris on the runway for a bonfire, and did what we could to secure all other lost items that might otherwise blow around and cause more injury to the birds.
