by The earthquake of the strength 8.8 off the coast of the Russia Kamchatka Peninsula had a wave of water races at the speed of a jetliner towards Hawaii, California and Washington State, which stayed warnings and alarm on Wednesday.
But when the Tsunami waves arrived, they did not cause devastation or death in the United States, and the flooding seemed to be in some places where warnings were issued.
This does not mean that the Tsunami was a “bust” that it was poorly predicted or that it was not a risk that said earthquake and tsunami researchers.
“You hear that Tsunami warnings warn and everyone immediately thinks of the last Hollywood film you saw, and then it comes at 3 feet and the people are like” What is it? “” We should count as a victory that a tsunami took place, we got a warning and it wasn’t the worst scenario. “
Here is what to know.
How strong was Kamchatka’s earthquake? And why did it change so much?
The first reports on the earthquake of Kamchatka from the United States Geological Survey have set it as 8.0 magnites. Later it was improved to a quake of 8.8 size.
“This is not unusual in these first minutes for very, very large earthquakes,” said Tobin. “Our standard algorithms to determine the size of an earthquake quickly saturate. It is like an amplifier and a lot of distortion.”
One of the first signs The earthquake was stronger than the initial seismic reports was a first measurement of a buoy about 275 miles southeast of the Kamchatka peninsula.
The buoy, which is part of the dart system (deep-ocean assessment and reporting of the tsunamis) of the national oceanographic and atmospheric administration, is connected to a sea floor printing sensor below the surface.
The sensor registered a 90-centimeter wave that is conspicuous for tsunami researchers.
“This is the second largest recording that we have ever seen in the Tsunami world,” said Vasily Titov, a high-ranking tsunami modeler in the Pacific Marine Environmental Laboratory from Noaa and added that it “a catastrophic tsunami propagation in the sea”.
Titov said the only higher reading was from the earthquake of Tōhoku and Tsunami 2011, which caused almost 16,000 deaths in Japan.
Seismic models later confirmed that the earthquake was a size of 8.8 on Wednesday, which means that according to a USGS calculation tool, it excluded almost 16 times as much energy as an earthquake of size 8.0.
Tōhoku was much bigger.
Tobin estimated that the earthquake solved 2-3 times as much energy as was observed in Kamchatka. Titov said the tsunami in Japan was also about three times larger.
In addition, Tobin said that the earthquake of Tōhoku “creates an anomally large shift of the sea floor”, which staggered and moved more water even for an earthquake of its size.
At Kamchatka “It is likely that there was less shift in the sea floor than in the worst case or in a worst case or worse for a size 8.8,” said Tobin, although more research is required to confirm this theory.

How did researchers make a forecast? How good was the forecast?
In two hours, the researchers produced a Tsunami forecast for “pretty much the entire Pacific and for warning points along the US coast,” said Titov with predictions in the water level at coastal teases and also for flooding the floods.
The tsunami took about eight hours to reach Hawaii and 12 hours to reach the California coast.
Titov, building the warnings of the national tsunami warning centers in Hawaii and Alaska, Titov, which was used, said, said that the models rely on seismic data and the network of more than 70 darts bojen, which along the Pacific Rim on the spot. The United States owns and operated more than half of the dart booths.
Titov said the models stated that North Shore areas from Hawaii Tsunami waves of about two meters or less would be preserved.
“Hilo was predicted two meters [6.5 feet] And it materialized at about 150 centimeters or 1.5 meters [5 feet]Titov said. “It is exactly the way we want it – a bit conservative.”
The same trend in parts of California, said Titov.
It will take some time to assess how well the models have been flooded, as reports on the extent of the floods are still in.
“We know that the floods have taken place in Hawaii. We do not know exactly that, but from the reports I saw on TV, it looks exactly as we have predicted,” said Titov.

Why were people in Hawaii evacuated for a five-foot wave?
Yong Wei, a Tsunami modeler and senior research scientist at the University of Washington and the NOAA Center for Tsunami research, said a 1.5 meter [5 foot] The Tsunami wave can be very dangerous, especially in flat waters in front of Hawaii.
Tsunami waves contain far more energy than wind waves that are far shorter in the wavelength (time between waves) and slower at speed.
Wei said that Tsunami waves of size that Hawaii hit can rise in the interior of “ten meters”, cause dangerous currents and cause damage to boats and other movable objects.

“People die. If they stay there and don’t get a warning, two meters can definitely kill people,” said Wei. “When they are on the beach, strong currents can definitely pull them into the sea and people will drown.”
Tobin said that the initial warnings were conservative, but appropriate, in his view.
“I don’t want people to think, oh, we had a warning and not much has happened, and it is POO IT -” I can ignore it, “said Tobin.” Warnings of nature have to be a bit of caution. “
Was that a historical event?
No. The Kamchatka Peninsula has a long history of earthquakes.
“This was an area that was ready for another earthquake, and in the past few weeks there have been many earthquakes in this region,” said Brealinyn Macinnes, professor at the Department of Geological Sciences at Central Washington University, which indicates an increased risk.
Before scientists had a strong understanding of the plate tectonics in 1952, an earthquake of 9.0 was able to step the Kamchatka peninsula off the coast in the same region and send a tsunami to the city of Severo-Kurilsk.
“The people in Russia were not really prepared for it. It was a very large earthquake, a big tsunami and they were unprepared,” said Macinnes.
According to Macinnes, the tsunami produced was between 30 and 60 feet in southern parts of the peninsula.
“Thousands of people were killed and basically the city was destroyed,” said Joanne Bourgeois, emeritus professor of sedimentology at the University of Washington, who has been studying the region’s earthquake history for about three decades.
How would the Tsunami warning system occur if the earthquake was closely at home?
The Kamchatka Tsunami is a megathrust -earthquake that is generated along the great rejection of the subduction zone when a tectonic plate is forced under another. The US west coast has a similar mistake called the Cascadia -subduction zone and which drives from North California to North California to North Vancouver Island off the coast.
“This is a kind of reflection in the Pacific,” said Tobin. “An 8.8 in a relatively low depth in Cascadia is definitely in the area of the scenarios. We could have a similar event here.”
In fact, Cascadia has the potential to produce much larger quakes, said Tobin. The modeling suggests that Cascadia Tsunami could produce up to 100 feet.
The earthquakes of the subduction zone typically generate tsunamis that come ashore in about 30 minutes to an hour, Titov said what the skills of the forecastists would put a strain on the prediction of tsunami effects along the US west coast.
According to Titov, more sea floor sensors, more computer processing and innovation with artificial intelligence algorithms are required to accelerate the prediction.
Tobin said the successful tsunami warning on Tuesday should stimulate investments in marine floor sensors and seismic surveillance stations off the coast along the subduction zone.
“This shows the value and meaning of Noaa and the USGS [U.S. Geological Survey] In these times when some of these government agencies were considered, “said Tobin. They showed their value.”
