HONOLULU (KHON2) — A new type of technology is being introduced in the long fight against Little Fire Ants (LFA).
Lanikai Pillbox Trail to temporarily close for Little Fire Ant treatment
May is invasive species awareness month, and the Oʻahu Invasive Species Committee has been busy implementing new technology to aid in the fight against LFA eradication with the use of drones.
WakeUp2Day's Chris Latronic went live in Kahaluʻu to learn more. He met with Erin Bishop, the Outreach Coordinator for the Oʻahu Invasive Species Committee & Timo Sullivan of Aloha Aina Drone Company to witness their current engagement of an LFA infestation area using a heavy-duty aerial drone.
The Ka'iwa Ridge Trail, popularly known as the Lanikai Pillbox Trail, was recently closed and was determined that an aerial approach would be the best option to treat the tricky ridge terrain with Aloha 'Āina Drones selected to support the project.
Drones are being used to deliver growth-inhibiting treatments to areas that are difficult to access by foot or by traditional methods that would normally take excessive personal time and effort.

'Drone technology is advancing our efforts to move this site from an active infestation to eradication,' said Erin Bishop. 'Drones offer a faster, safer and more cost-effective way to treat large, steep areas.'
As of April 2025, there have been over 80 LFA detections on island.
Bishop added, 'We're thrilled to move forward with this innovative approach — without it, the threat of LFA spreading into surrounding residential and recreational areas would remain. This marks a major step forward in protecting our communities and environment.'

Google Has Quietly Been Detecting Earthquakes by Sensing Rumbling in Android Phones For Years

Google has for years been harnessing the power of its Android smartphones to detect and measure tens of thousands of earthquakes. In a new paper published in the journal Science, researchers from the search giant described how they used motion sensors from its two billion-strong network of phones running Android between the years 2021 and 2024 to detect and alert quakes to users in almost 100 countries around the world. Known as "Android Earthquake Alerts" (AEA), this early warning system has uses the smartphones' accelerometers to detect telltale vibrations as they happen and inform residents of quakes in their areas. With its two-tiered severity levels — the weaker "be aware alert" for lower-magnitude quakes that sends typical push notifications, and the more pressing "take action alert" for moderate or extreme shakes that issues a loud beeping alarm that overrides "Do Not Disturb" settings — Google boasts that it has warned of more than 11,000 quakes. While such a system has invariably saved lives, however, AEA is far from flawless. In the case of Turkey's deadly quakes in 2023 that claimed more than 55,000 lives and injured over 100,000 people, the company now admits that it erroneously sent its lower-level notifications to hundreds of thousands of people — a massive failure during one of the deadliest natural disasters in recent history. Both in the Science paper and in a statement to BBC, Google admitted that it only sent 469 "Take Action" alerts during the first of the two earthquakes that struck Turkey and Syria in February 2023, and instead mass-notified half a million people with the "Be Aware" version, the less severe of the two warnings. Because the first earthquake occurred at around 4:15 in the morning, that quieter warning likely went unseen by people who were asleep and had their phones silenced. That discrepancy appears to be the result of bad seismic readings from the phones' sensors. Initially, the system's algorithms estimated that the first quake was between a 4.5 and 4.9 on the moment magnitude scale (MMS), but it was actually a far more serious 7.8. During the second quake, the AEA also underestimated the magnitude, sending only 8,158 "Take Action" alarms and almost four million "Be Aware" alerts. (That shoddy algorithm, the company says, has since been updated.) Until now, Google deflected blame for the system's failure, even after the BBC investigated the AEA in the aftermath of the quakes and found it to be severely lacking. Though this sort of admission is better late than never, it's still concerning that Google took more than two years to admit the system's failures during the Turkey earthquakes. With so many people relying on the tech monolith for life-saving alerts, taking accountability for the AEA's failures is paramount — and that accountability should have been much swifter.

Here's how your phone could save your life if an earthquake hits

A worldwide Android smartphone-based earthquake detection and early warning system can detect seismic activity in real time Could your smartphone save your life? If an earthquake is occurring, it just might. A worldwide Android smartphone-based earthquake detection and early warning system can detect seismic activity in real time – and deliver life-saving alerts that are just as effective as that of traditional seismic networks, according to a new study published July 17 in the journal Science. The Android Earthquake Alerts (AEA) system, which was developed by engineers at Google and the University of California-Berkeley, uses the phones' sensors to detect seismic activity and deliver early-warning alerts to users before dangerous shaking begins. "Earthquakes are a constant threat to communities around the globe," wrote Google engineer Mark Stogaitis on a Google blog post about the new study. "While we've gotten good at knowing where they're likely to strike, we still face devastating consequences when they do." "What if we could give people a few precious seconds of warning before the shaking starts? Those seconds can be enough time to get off a ladder, move away from dangerous objects and take cover," he wrote. Safety: This is what to do before, during and after an earthquake Indeed, the widespread use of smartphones globally has created a powerful platform for sensing and delivering earthquake alerts, according to a statement from Science. "While the sensors in smartphones are not as precise as those in traditional seismic stations, they are still capable of detecting ground shaking during significant earthquakes." How does it work? According to Google, "the accelerometer in an Android phone, the same sensor that flips the screen when it's turned sideways, can also detect the ground shaking from an earthquake. If a stationary phone detects the initial, faster-moving 'P-wave' of an earthquake, it sends a signal to our earthquake detection server, along with a coarse location of where the shaking occurred." The system then quickly analyzes data from many phones to confirm that an earthquake is happening and estimate its location and magnitude. The goal is to warn as many people as possible before the slower, more damaging "S-wave" of an earthquake reaches them. The system sends out two types of alerts: How successful has it been? According to Google, feedback has been overwhelmingly positive. Of the more than 1.5 million people who responded to a survey, 85% found the alerts to be "very helpful." Overall, during its first three years of operation (2021-2024), the AEA system detected an average of 312 earthquakes per month, spanning magnitudes from M 1.9 to a maximum of M 7.8 across 98 countries, according to the study. "The system has now detected over 18,000 earthquakes, from small tremors of M1.9 to major quakes reaching M7.8," Stogaitis wrote. "For the events significant enough to warn people, alerts were issued for over 2000 earthquakes, culminating in 790 million alerts being sent to phones worldwide. This included more than half-a-million people in Turkey and Syria who received an alert on February 6, 2023, just before a magnitude 7.8 earthquake struck. according to a report. The impact has been a greater than tenfold change in the number of people with access to earthquake early warning systems. "In 2019, only about 250 million people had access. Today, thanks in large part to the Android system, that number has increased to 2.5 billion," he said. As an example, in the magnitude 6.2 earthquake in Turkey in April 2025, the first alert was issued 8 seconds after the earthquake began. People who experienced moderate to strong shaking had a warning time of a few to 20 seconds. In this event, over 16 million alerts were delivered. 'Comparable to established national systems' Stogaitis concluded that "what's most exciting is that our system is constantly learning and improving... In the future, this system could not only provide warnings but also deliver rapid post-earthquake information to emergency responders, helping them to quickly assess the areas most in need." According to the study, "AEA demonstrates that globally distributed smartphones can be used to detect earthquakes and issue warnings at scale with an effectiveness comparable to established national systems. (However,) large earthquakes remain the most important and challenging for all earthquake early warning systems."

Smartphones could help detect earthquakes and send early warnings, study finds

Scientists have developed a new system that turns Android smartphones into real-time earthquake detectors, potentially creating a faster way to warn people before a major tremor hits. The system, developed by researchers at Google, the US Geological Survey (USGS) among others, uses data from millions of phones to identify the earliest shaking signals from an earthquake. When a cluster of devices registers the same ground movement, the system flags it and sends alerts to others in nearby areas. The study, published in Science, found the network detected more than 300 earthquakes a month. In areas where alerts were sent, 85 per cent of people who later reported feeling the earthquake said they had received the alert. Of those, 36 per cent received it before the shaking began, 28 per cent during, and 23 per cent after. While the system does not replace traditional seismic sensors, it could offer a scalable, low-cost early warning tool for regions without dense scientific networks, the study says. The authors said it was especially promising for developing countries where smartphones are common but seismometers are rare. In a statement, Google said the system could give people 'a few precious seconds of warning before the shaking starts'. 'Those seconds can be enough time to get off a ladder, move away from dangerous objects and take cover.' The alerts rely on detecting fast-moving P-waves, which precede the more destructive S-waves during an earthquake. If enough phones detect the P-waves, the system sends warnings to users who may be seconds away from feeling shaking. These seconds can be enough to duck for cover, stop surgery or pause critical infrastructure. The Android Earthquake Alerts System, which began rolling out in 2020, now operates in several countries including the United States, Japan, Greece, Turkey and Indonesia. It is built directly into the Android operating system and does not require users to download a separate app. Map shows countries where Android's earthquake alert system is active (light green). Red and yellow mark areas that experienced strong (MMI 5+) and light (MMI 3–4) shaking, respectively. Grey dots show detections without alerts. Alerts in California, Oregon and Washington come from ShakeAlert (dark green). (Google) While the accuracy is not as high as scientific sensors, the researchers found that alerts from smartphones worked best in urban areas with high phone density and reliable data connections. In rural areas, coverage is more sparse and detection slower. The study builds on earlier crowdsourced earthquake initiatives like the MyShake app but benefits from being embedded natively on millions of devices. 'We believe crowdsourced systems will become increasingly important,' the authors wrote. 'By combining traditional sensors with data from personal devices, it is possible to build more resilient, inclusive early warning systems.'
