De los terremotos a los huracanes: así funcionan los sensores que revolucionan la predicción de tormentas
Investigadores de seguimiento interno de huracanes en la Universidad de Stanford demostraron que instrumentos usados para estudiar el movimiento de la Tierra también pueden revelar cómo funciona un huracán por dentro. El estudio, publicado en Science, apunta a una vía para mejorar la previsión de cómo evolucionan y se intensifican estas tormentas.
Los sismómetros y los micrófonos de infrasonido pueden ayudar a entender y prever mejor los huracanes porque registran dos señales clave cerca de la superficie: la turbulencia de la capa límite y las fluctuaciones de presión atmosférica. Al comparar esos datos con mediciones convencionales, los investigadores comprobaron que ambos sensores permiten seguir rasgos internos de la tormenta, incluido el paso del ojo y de la pared del ojo.

La investigación se apoyó en el paso del huracán Isaac por la costa de Luisiana en 2012, cuando la tormenta atravesó estaciones que ya estaban instaladas para cartografiar el interior de la Tierra. Qing Ji, autora principal del estudio, afirmó que hallaron “una forma nueva y eficaz de recopilar información valiosa sobre huracanes a partir de sensores sísmicos y acústicos”.
El experto realizó la investigación como estudiante de doctorado en el laboratorio de Eric Dunham, profesor de geofísica en la Escuela de Sostenibilidad Doerr de Stanford y autor principal, quien sostuvo que el estudio mostró que la geofísica y la ciencia atmosférica pueden aportar información mutua.
En este caso, los sismómetros detectan los movimientos del suelo y permiten precisar cuándo un huracán toca tierra. Los micrófonos de infrasonido, por su parte, registran ondas sonoras de baja frecuencia inaudibles para el oído humano y siguen los cambios de presión atmosférica a lo largo del tiempo.

Ese doble registro resulta útil en la capa límite, la zona más próxima al suelo donde se mezclan viento, calor y humedad. Medir la turbulencia en esa franja es clave para prever si una tormenta se fortalece o se debilita.
Los investigadores añadieron a los datos sísmicos los registros de infrasonido y obtuvieron una medición continua de las fluctuaciones de presión turbulentas. El conjunto combinado identificó con claridad el ojo tranquilo del huracán Isaac al pasar sobre ciertas estaciones, antes y después de la pared del ojo.
Después compararon ese material con datos convencionales de la capa límite y encontraron una gran concordancia. Ji dijo que el trabajo demuestra “la validez de este enfoque y la oportunidad que ofrece para utilizar este tipo de datos de una manera diferente”.
El origen del hallazgo fue accidental, porque Isaac pasó cerca de estaciones instaladas para otro proyecto geofísico en una región con pocos sensores sísmicos. Ji reconoció que tuvieron “algo de suerte” por la cercanía de los equipos a la trayectoria del huracán.

En un estudio previo sobre esas estaciones, Ji y Dunham descartaron la idea de que la instrumentación quedara saturada por ondas sísmicas superpuestas de toda la tormenta. Dunham explicó que observaron que la señal del sismómetro estaba dominada por la turbulencia local a una escala de pocos kilómetros.
La colaboración se amplió con Ipshita Dey, doctorada en Ciencias del Sistema Terrestre en 2024, que estudiaba la capa límite en el laboratorio de Morgan O’Neill. Dey señaló que esa cooperación permitió comprobar si las señales sísmicas procedían de rasgos de pequeña escala dentro del huracán y que ese trabajo conjunto llevó el estudio “al siguiente nivel”.
Los métodos habituales para obtener datos de la capa límite incluyen aeronaves que lanzan sensores en paracaídas, además de boyas, torres de medición de viento y radares. Las boyas y las torres solo ofrecen lecturas cercanas a la superficie, el radar aporta instantáneas y los vuelos pueden poner en peligro a los pilotos.
Isaac tocó tierra como tormenta de categoría 1 y en unos 100 segundos movió el suelo una fracción de milímetro, en una señal comparable a la de un pequeño terremoto imperceptible. El equipo prevé ampliar el análisis a otros huracanes y plantea añadir sensores para crear estaciones multifuncionales con utilidad sísmica y atmosférica.
Si ese enfoque se consolida, podría ampliar la base de datos para estudiar huracanes y otras tormentas intensas. Esa información también podría influir en decisiones sobre infraestructuras, evacuaciones, mensajes públicos y preparación ante tormentas para proteger a las comunidades.

El-Sayed win kicks Democrats’ Midwest ideological battle into high gear — and some Dems fear November fallout
Wisconsin gubernatorial candidate Francesca Hong pressed on past far-left comments
Wisconsin Democratic gubernatorial candidate Francesca Hong defends her past controversial social media posts during an interview with Dana Perino. Hong discusses her support for defunding police, abolishing ICE and her socialist platform. Recent polling shows Hong trailing her Republican opponent Tom Tiffany by three percentage points as campaign finance reports reveal a massive fundraising gap between the candidates.

The battle between the left-wing and the center-left establishment for the ideological future of the Democratic Party is staying put in the Midwest.
After far-left candidate Abdul El-Sayed narrowly edged out more moderate Rep. Haley Stevens this week in battleground Michigan’s high-stakes Democratic Senate primary, the spotlight now shifts to nomination showdowns next week in Wisconsin and Minnesota.
At stake: a top-tier Senate showdown in Minnesota that’s among a dozen races nationwide that will determine if the Democrats can win back control of the chamber from the GOP, and a gubernatorial face-off in crucial swing-state Wisconsin where Republicans are aiming to flip the governor’s mansion.
«Michigan proved that working people are ready for something different, and Wisconsin is next,» Democratic candidate for governor Francesca Hong wrote following El-Sayed’s victory.
EL-SAYED’S VICTORY GIVES DEMOCRATS’ LEFTWARD LURCH MORE LEGS

Hong, a state representative and Democratic Socialists of America (DSA) member, is the polling frontrunner in a Democratic gubernatorial nomination showdown that’s been rocked this summer after two major contenders dropped out and another candidate re-entered the race.
The primary winner will likely face off in the general election with Republican Rep. Tom Tiffany, the overwhelming polling and fundraising frontrunner for the GOP gubernatorial nomination, in the race to succeed Democratic Gov. Tony Evers, who decided against running for a third term.
Hong, a former chef, is backed by top nationally known progressives, including Reps. Ilhan Omar of Minnesota and Ro Khanna of California, a potential 2028 Democratic presidential contender.
She is running on a platform that includes guaranteed paid leave and a one-year moratorium in Wisconsin on building AI data centers. Hong has faced scrutiny over years-old social media posts calling for defunding and abolishing the police. Hong says she no longer supports cutting police budgets or abolishing police departments.
MEET THE FAR LEFT INSURGENTS WAGING WAR ON THE DEMOCRATIC PARTY IN THE 2026 MIDTERMS

But Hong’s made national headlines in recent days over a resurfaced 2020 social media post that the country should «cancel Thanksgiving» in order to «stop celebrating colonialism and the original superspreader event that killed Indegenous folx [sic.] and women.» It’s a comment she has since walked back amid backlash, and now says that Thanksgiving is her «favorite holiday.»
There’s a growing number of moderate Democrats who worry that if Hong captures the gubernatorial nomination, as many expect, it will give Tiffany a big boost in his bid to flip the governor’s office.
A Wisconsin-based Democratic strategist who asked to remain anonymous to speak more freely argued with Hong at the top of the ticket, «it will hurt Democrats down ballot, in key congressional and legislative races» in the Midwestern battleground.
In Minnesota, which also holds primaries next Tuesday, the Democratic Party’s civil war is also on display as progressive Lt. Gov. Peggy Flanagan and more moderate Rep. Angie Craig are the top two contenders battling for the party’s nomination. The current senator, Democrat Tina Smith, is retiring at the end of this year.

A primary victory by Flanagan, who is backed by progressive champions Sens. Bernie Sanders of Vermont and Elizabeth Warren of Massachusetts, may boost the GOP hopes of flipping the seat in a blue-leaning but competitive state.
Michigan’s primary came in the wake of left-wing victories in Democratic primaries this spring and earlier this summer in deep blue congressional districts across the country, including in New York City and Denver, and in the extended race for Maine’s Democratic Senate nomination.
More than $80 million was spent on the Michigan Senate primary, making it the most expensive Democratic Senate nomination contest in history. Much of the money came from outside groups supporting Stevens or opposing El-Sayed. The largest spender was United Democracy Project, a political action committee aligned with the American Israel Public Affairs Committee, which is best known by its acronym AIPAC.
Adam Green, co-founder of the Progressive Change Campaign Committee (PCCC), a leading group on the left, referred to El-Sayed’s narrow margin over Stevens and told Fox News Digital that «any win against $60 million dollars of outside spending by AIPAC and corporate interests is a giant win and sets us on a path of proving our case in November to shake up the system.»
El-Sayed’s razor-thin win was accompanied by two other progressive victories.
William Lawrence, a co-founder of the Sunrise Movement climate advocacy group, edged out two more moderate Democrats in Michigan’s 7th Congressional District, a Republican-controlled swing seat that is among roughly two dozen races expected to help determine control of the House.
Lawrence, who was backed by Sanders and El-Sayed as well as several prominent progressive groups, will face Republican Rep. Tom Barrett in the general election.

And in Michigan’s heavily Democratic 13th Congressional District, Rep. Shri Thanedar, who was supported by top House Democratic leaders, was narrowly defeated by state Rep. Donovan McKinney. McKinney was backed by Sanders, El-Sayed and «Squad» members Reps. Ilhan Omar of Minnesota, Ayanna Pressley of Massachusetts and Summer Lee of Pennsylvania.
There was a setback for the far-left: DSA member and former Squad member former Rep. Cori Bush of Missouri was crushed by Democratic Rep. Wesley Bell in their rematch, as she unsuccessfully tried to win back her old seat in Congress representing St. Louis.
But El-Sayed’s victory and the potential wins by the left next week are further fueling the ongoing Republican push to characterize all Democrats on the ballot in the midterms as far left radicals, or as President Donald Trump calls them, «communists.»
ONLY ON FOX DIGITAL: MIKE ROGERS ARGUES ABDUL EL-SAYED IS ‘A SPECIAL SAUCE OF CRAZY’
Vice President JD Vance, in an interview Wednesday on Fox News «The Ingraham Angle,» argued that «the base of the Democratic Party just wants radicals. It wants these DSA types, it wants people who hate even the idea of private property ownership.»
Whether the GOP messaging is effective will be answered on Election Night, in November’s midterms.

US says North Korea missile launch poses no immediate threat, ‘consulting closely’ with allies
NEWYou can now listen to Fox News articles!
U.S. Indo-Pacific Command vowed Thursday that the U.S. «remains committed to the defense of the U.S. homeland and our allies in the region» after North Korea test-fired a ballistic missile.
The launch of the short-range ballistic missile unfolded ahead of large-scale, annual exercises to be conducted by the U.S. and South Korean militaries later this month. South Korea’s Joint Chiefs of Staff said a projectile from North Korea’s eastern Wonsan area was detected around 5 p.m. local time.
«We are aware of the missile launch and are consulting closely with our allies and partners. Based on current assessments, this event does not pose an immediate threat to U.S. personnel or territory, or to our allies,» U.S. Indo-Pacific Command said in a statement.
«The United States remains committed to the defense of the U.S. homeland and our allies in the region,» it added.

South Korea’s military bolstered its surveillance posture and is closely coordinating with the U.S. and Japan in the wake of the event, according to South Korea’s Joint Chiefs of Staff.
Japanese Defense Minister Shinjiro Koizumi said the missile landed in the waters off North Korea’s east coast and that there were no reports that the weapon reached Japanese territory.
Koizumi added that North Korea’s repeated missile launches pose a threat to Japan and the region and that Tokyo lodged a protest to Pyongyang through their embassies in Beijing. South Korea’s presidential national security council called the North Korean launch «a provocation» that violates U.N. Security Council resolutions and urged the North to stop it.
It was North Korea’s first ballistic missile launch since late June, when it tested a tactical ballistic missile with a «special mission» warhead and other weapons. After watching the testing activities, leader Kim Jong Un said at the time that the military needed to bolster its «deadly and destructive offensive posture.»

South Korean and U.S. officials haven’t yet released details about this year’s Ulchi Freedom Shield joint exercise, but the drills are typically held in the latter half of August.
«This annual exercise aims to build understanding between Combined Forces Command, United States Forces Korea, the United Nations Command, and ROK Joint Chiefs of Staff (JCS), ROK government agency, ensuring their ability to fortify the combined defense posture and enhance Alliance response capabilities against a spectrum of security threats,» United States Forces Korea said about the exercises on its website.
«It will feature live, virtual, constructive and field-based training, engaging personnel from the various military services,» it added.

Burrito debate rips open GOP civil war on affordability: ‘We will lose, and deserve it’
NEWYou can now listen to Fox News articles!
A debate over whether a burrito should cost $20 has ignited a Republican civil war over affordability and the party’s appeal to younger voters ahead of the midterm elections.
The clash began Wednesday when Turning Point USA spokesman Andrew Kolvet shared a college student’s complaint that basic purchases have become prohibitively expensive.
«One of our TPUSA college students gave me his take on affordability: ‘A burrito shouldn’t cost $20,’» he posted to X on Wednesday. «Yeah, a lot of this is a hangover from Covid and Biden-era inflation, but the lived experience is the same: It just feels like basic things cost too much.»
Fiscal conservatives took the position that food is generally affordable if one cooks for themselves and that purchasing a $20 burrito should be considered an occasional luxury. Those aligned with the populist wing of the GOP, meanwhile, argued that traditional conservatives are out of touch with the youth and that the Republican Party faces electoral peril unless it can meaningfully address affordability concerns.
NEW POLL COMPLICATES VANCE’S STATUS AS TRUMP’S LIKELY 2028 HEIR APPARENT

«Just hearing about this dumb $20 burrito debate so just thought I’d make the losers on social media angry before going to bed,» Rep. Dan Crenshaw wrote on Wednesday night. «Stop whining, get a job, eat Ramen like the rest of us did in college, on a budget with 4 roommates. The market doesn’t care what you think something ‘should’ cost.»
RealClearInvestigations senior writer Mark Hemingway, however, said that such an approach to affordability concerns could prove toxic to the GOP.

«Andrew [Kolvet] is absolutely right about this, and pundits deflecting because you can cook at home cheaper are not helping,» he said. «Eating a burrito once in a while should not be an aspirational lifestyle, for crying out loud.»
«The comments saying stick to the dining hall or buy microwaveable burritos are missing the ENTIRE point,» Defense of Freedom Institute spokeswoman Angela Morabito said. «If the Right’s ‘solution’ to the affordability crisis is telling people to eat worse food, we will lose, and we will deserve it.»
Chipotle burritos generally run between about $9 and $12 depending on location, with cheaper restaurants, such as Taco Bell, offering more affordable options. Some fiscal conservatives also pointed out that young people can save money by preparing meals at home.
«A burrito only costs $20 when you buy it on Door Dash because you’re too lazy to walk over to Chipotle or Taco Bell (where you can get one for $3.99),» Fox News contributor Marc Thiessen wrote in response to a populist arguing that the GOP could surrender ground to socialists by not addressing affordability. «When I graduated I lived on ramen noodles, had two roommates, and worked two jobs. I didn’t whine about affordability, I worked hard so I could one day afford a better life.»

Vice President JD Vance then added to the debate, responding to Thiessen.
«I’m surprised to hear Mark say this. If you’ve ever met him in person, it’s quite obvious the man has never missed a burrito,» the vice president wrote.
Bradley Devlin, politics editor at the Daily Signal, claimed that some involved in the burrito discourse were ignorant of financial sacrifices he says are quite common among young people.
«The Burrito Discourse has exposed that so people with thoughts on the youths have not spoken to one in years,» he wrote. «They do not expect to live off delivered food from bespoke restaurants and live on their own. I don’t know a single 20 something who lives on their own right now. Having a college degree and two jobs is around the highest it’s ever been. ‘The college premium’ has dried up.»
Others responded to the debate in jest.
«I don’t care for burritos,» Daily Wire host Michael Knowles posted.
