LOS ANGELES >> Stress on the San Andreas Fault system has reached a 1,000-year high, according to new research from the University of Hawaii.

Higher stress on a fault means the pressure that causes earthquakes is building.

“Our results show that stress levels on multiple fault segments are now at or above the highest values seen in the past millennium and that the region may be capable of a large through-going rupture involving both fault systems,” said lead author Liliane Burkhard, research affiliate in the Hawai‘i Institute of Geophysics and Planetology at the UH-Manoa School of Ocean and Earth Science and Technology and a scientist at the University of Bern, Switzerland.

“We also found that Cajon Pass may act as an ‘earthquake gate:’ sometimes blocking large ruptures from crossing between the faults, and sometimes allowing them to pass through and involve both systems in a single event,” Burkhard said in a UH news release.

Multi-fault ruptures, where earthquakes continue from one fault to another, have occurred in multiple recent earthquakes, including the 2011 Tohoku, Japan, earthquake and became a part of the U.S. Geological Survey’s earthquake forecasting model in 2015.

This type of quake would be possible if the Cajon Pass, which is between the San Bernardino and San Gabriel mountains in Southern California, allows an earthquake to pass through it, meaning rather than affecting the area along one fault line, a quake could continue along a second fault and affect a larger area.

But Kate Scharer, a co-author of the study and a seismologist with the U.S. Geological Survey in Pasadena, said there’s no reason for California residents to be significantly more concerned than they were before hearing about the study.

While the stress has reached a milestone, the pressure was already high and the fault has been overdue for a large earthquake for some time, according to the study.

It has been over 100 years since a major tectonic rupture has affected the greater Los Angeles area, which means stress on the tectonic plates has been building, according to the study.

The 1857 Fort Tejon earthquake was the most recent “big one” to affect Southern California, while the San Jacinto Fault saw moderate earthquakes in 1918, 1968 and 1987, according to the study. A long period without seismic activity “raised concern that the next slip event in this region could be both large and complex,” the study says.

As more time passes, an earthquake becomes more likely because built-up energy needs to be released.

“We know for the southern San Andreas and the San Jacinto fault that they were just a little bit over the average (time between earthquakes) from looking at the geologic record,” Scharer said.

Those two faults are at highest risk for an earthquake because they are the fastest moving, she said.

The study looked at a geologic record of earthquake activity across the past 1,000 years, giving a new perspective on the total stress the San Andreas and San Jacinto fault systems are under. Tectonic plates are always moving and accumulating stress, save for those few seconds where an earthquake is happening.

When an earthquake releases built-up stress from hundreds to thousands of years of an interseismic period, energy is felt in the form of an earthquake, Scharer said.

Earthquake forecast models from the U.S. Geological Survey are “a reminder that damaging earthquakes are inevitable for California,” and the new study highlights just how much stress the fault systems are under as Californians prepare for the “big one,” according to the USGS.

The study’s importance is with the calculations of stress the researchers did. After a geologic record, which looks at prehistoric earthquakes and is assembled by digging trenches across faults and looking at layers that have been offset in the past, is created, the researchers were able to determine that the stress on the San Andreas fault is at a 1,000-year high.

The stress level could influence if the Cajon Pass facilitates an earthquake spreading from one fault to another, or if it stops an earthquake from doing so. When the stress levels on both faults are similar, both faults appear to rupture jointly, according to the study.

Using a physics-based computer model, the researchers found that that the stress that would normally be released in large earthquakes has continued to accumulate and is at unprecedented levels.

The Cajon Pass, the study suggests, could facilitate a joint rupture of both the San Andreas and San Jacinto faults simultaneously, which could be “significantly more damaging than a single-fault event,” affecting densely populated areas including Los Angeles, San Bernardino, Riverside and the Coachella Valley, according to the UH news release.

“This is not a prediction of when an earthquake will happen,” Burkhard said. “However, studies like this are important contributions to national and global earthquake hazard research in that we are using rigorous, quantitative science to better understand the risk facing millions of people. What we can say is that the system is critically stressed, and that physics-based models like this one give us a clearer picture of the range of scenarios we should be prepared for. That information matters for hazard assessments, infrastructure planning, and emergency preparedness.”

HONOLULU (HawaiiNewsNow) – The Honolulu Police Department shut down an illegal gambling operation in Kakaako.

On Thursday, officers with the Narcotics/Vice Gambling detail, along with the District 1 Crime Reduction Unit, Forfeiture Detail and Specialized Services Division, executed a search on a property on Kawaiahao Street.

HPD said they recovered 19 gaming machines and more than $7,000 in cash.

The department said they remain committed to addressing illegal gambling operations.

“The June 25, 2026, operation is the 19th illegal gambling search warrant executed so far in 2026 and the third in the month of June,” said HPD Maj. Jerome Pacarro. “Enforcing the law against these illegal operations helps prevent related criminal activity from taking root and strengthens the safety of our communities.”

To report illegal gambling, call the Narcotics/Vice 24-hour hotline at (808) 723-3933 or use the online form here.

For the 14th year, nonprofit Hawaii Island LGBTQ+ Pride will host a celebration of the LGBTQ+ community this Saturday in downtown Hilo, featuring a parade and festival.

The theme and slogan of this year’s festivities is “Strong Together, Proud Forever!” said HILGBTQ+ Vice President Phill Russell. He said the event’s planning committee chose the slogan to highlight the need to show resilience and strength amid the current political climate. The Trump administration has rolled back numerous protections for LGBTQ+ individuals.

“The LGBTQ+ community is facing a lot of challenges federally, and so it just becomes even more important for us to stand together,” Russell said. “We appreciate everyone in the community, all of our allies, everyone that steps up and helps uplift the LGBTQ+ community, calls out stigma and homophobia and transphobia when they see it, and looks out for our LGBTQ plus brothers and sisters here on the island.”

While he said the event has drawn some protesters in recent years, it is a small number compared to the 500 to 700 community members he estimates typically attend to celebrate and show support.

“Luckily, all the supporters in the love far outnumber the hate in the bigotry, so we’re able to kind of ignore that,” he said. “We are getting record-breaking crowds that increase every single year. Seeing all of the folks, the families — it’s very heartwarming.”

Russell said that he thinks having public events such as this one play a role in advancing LGBTQ+ rights and reducing hate and stigma.

“I feel like it’s important to keep Pride going, because the visibility matters … .,” he said. “It’s hard to hate someone for being gay when you generally like them, and you’re already friends with them, and you’ve been friends with them forever, or they’re your kid or they’re your auntie — so that kind of … breaks down those walls.”

While Pride events take place around the world throughout the month of June, Russell said the Hilo celebration is special, with a focus on being community-oriented and family-friendly.

“I’ve been told by so many people that come from other islands, from other events like, ‘wow, this is like the most wholesome, family-friendly Pride I’ve ever been to,” he said. “It’s that Hilo touch, that Big Island touch, that makes it what it is and all the people that come together to make it happen.”

This year’s parade will begin at 11 a.m. starting at Kamehameha Avenue and Ponahawai Street proceeding down Keawe Street, back to Kamehameha, and ending at the Mo‘oheau Bandstand, where the festival will kick off at noon.

The festivities will continue until 4:30 p.m., featuring drag and aerial arts performances, dozens of local vendors and info booths, food, a bounce-house, scavenger hunt for kids and live music.

“There’s a great lineup of bands and performers at the bandstand,” Russell said. “We want everyone to come out and dance, enjoy the day. It’s going to be beautiful.”
