Each weekday, catch up on the 5 most pressing stories to start your morning in 3 minutes or less.  <\/p>\n<p>Cellphones these days are for everything, and one of their most important functions has become emergency alert systems.<\/p>\n<p>Cellphone emergency alerts aren&#8217;t foolproof. Could blaring sirens help during the next big fire?<\/p>\n<p>Cellphone alerts are far from foolproof, though, as we experienced during January\u2019s devastating fires. In west Altadena, warnings came too late or not at all. Cell service went out in many cases. Not everyone has access to a smartphone or is signed up for alerts.<\/p>\n<p>And if a disaster hits in the middle of the night, cellphones are likely to be off or silenced.<\/p>\n<p>After January\u2019s fires, many survivors I spoke with asked: Why don\u2019t we use tornado sirens like communities in the Midwest to warn of fires?<\/p>\n<p>The answer, as usual, is complicated. Like any alert system, public education \u2014 and trust \u2014 is key. And sirens can\u2019t replace cellphone alert systems, which are more targeted and can be easily accessed by most people, if they&#8217;re signed up.<\/p>\n<p>Emergency management officials and a fire battalion chief said sirens can be a life-saving tool when cell service goes out or amid widespread power outages.<\/p>\n<p>While sirens may make sense for certain communities and can fill gaps in digital emergency alerts, they\u2019re far from a silver bullet. Experts cautioned that sirens have limitations, such as:<\/p>\n<ul>\n<li>They can be impossible to hear from inside double-pane or triple-pane windows, especially with a TV on or for people with hearing impairments.\u00a0<\/li>\n<li>Topography that blocks cell service \u2014 rolling hills, mountains \u2014 can also block the sound of sirens.<\/li>\n<li>They\u2019re expensive and require ongoing maintenance.<\/li>\n<li>They can be confusing without proper public education. For example, Maui officials chose not to use Lahaina\u2019s siren system during the deadly 2023 wildfires because they were <a class=\"Link\" href=\"https:\/\/abcnews.go.com\/US\/maui-official-defends-sirens-deadly-wildfires\/story?id=102344576\" target=\"_blank\" data-cms-ai=\"0\" rel=\"noopener\">worried people would think the alert was for a tsunami and end up heading toward the flames<\/a>.\u00a0<\/li>\n<\/ul>\n<p>LAist asked the L.A. County Office of Emergency Management if officials might consider sirens, but it declined to comment until an after-action report about the January fires is complete.<\/p>\n<p>\u201cThe McChrystal After-Action Review is taking a comprehensive look at the capabilities the county possesses to alert and warn the public during emergencies,\u201d a spokesperson for the office wrote to LAist. \u201cUpon release of findings, we will look at the recommendations to see what improvements or enhancements to our alerting tools can best serve our communities.\u201d<\/p>\n<p>A brief history of sirens<\/p>\n<p>Sirens were first developed for another type of disaster \u2014 war. You can find remnants of World War II and Cold War-era air raid sirens in <a class=\"Link\" href=\"https:\/\/www.kcrw.com\/news\/articles\/where-are-las-cold-war-sirens\" target=\"_blank\" data-cms-ai=\"0\" rel=\"noopener\">cities<\/a> <a class=\"Link\" href=\"https:\/\/www.sbsun.com\/2022\/05\/31\/what-happened-to-some-of-the-air-raid-sirens-in-san-bernardino-riverside-counties\/?clearUserState=true\" target=\"_blank\" data-cms-ai=\"0\" rel=\"noopener\">across Southern California<\/a>. In the mid-20th century, such sirens were novel technology. Some cities and towns eventually used them to alert other disasters and to call volunteer firefighters to stations.<\/p>\n<p>But between the 1980s and mid-2000s, many of these aging sirens were decommissioned because they required costly maintenance \u2014 and because newer, more targeted technologies replaced them.<\/p>\n<p>    <img decoding=\"async\" class=\"Image\" alt=\"A black and white photo of four middle-aged men with light skin tone wearing suits and ties and shaking hands in front of a tall air raid siren. \" data-image-size=\"articleImage\"  width=\"649\" height=\"800\" src=\"https:\/\/scpr.brightspotcdn.com\/dims4\/default\/d1b5f5f\/2147483647\/strip\/true\/crop\/649x800+0+0\/resize\/649x800!\/quality\/90\/?url=http%3A%2F%2Fscpr-brightspot.s3.us-west-2.amazonaws.com%2F6a%2F18%2Fc54d66554c138de4005539d36904%2Fphotos-49800-large.jpg\" loading=\"lazy\" bad-src=\"data:image\/svg+xml;base64,PHN2ZyB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciIHZlcnNpb249IjEuMSIgaGVpZ2h0PSI4MDBweCIgd2lkdGg9IjY0OXB4Ij48L3N2Zz4=\"\/><\/p>\n<p> An air raid siren that was installed in Van Nuys in 1956. <\/p>\n<p>(<\/p>\n<p>Courtesy L.A. Public Library<\/p>\n<p>)<\/p>\n<p>At the same time, these sirens became less effective as cities sprawled and buildings modernized. For example, newer standards of double- and even triple-pane windows makes it hard to hear even today\u2019s sirens from inside with the windows closed, said David Acu\u00f1a, a battalion chief and public information officer with the California Department of Forestry and Fire Protection, or Cal Fire.<\/p>\n<p>With the rise of pagers, and then cellphones, sirens largely went out of vogue, he said.<\/p>\n<p>\u201cSirens were the technological advancement in the 1920s, 1930s, 1940s. Instead of having to go door-to-door, now we get to have the siren,\u201d Acu\u00f1a said. \u201cTechnology has surpassed that since then.\u201d<\/p>\n<p>L.A., for example, <a class=\"Link\" href=\"https:\/\/www.latimes.com\/archives\/la-xpm-2007-apr-29-me-then29-story.html\" target=\"_blank\" data-cms-ai=\"0\" rel=\"noopener\">decommissioned its air raid siren system in 1985<\/a>.<\/p>\n<p>Where sirens are now<\/p>\n<ul class=\"InfoboxModule-items\">\n<li class=\"InfoboxModule-items-item\">\n<p>Communities across California still use sirens to alert their residents of a variety of emergencies.\u00a0<\/p>\n<p>Here in Southern California, sirens are mostly used in coastal areas, historically to warn of tsunamis. For example, <a class=\"Link\" href=\"https:\/\/www.huntingtonbeachca.gov\/departments\/fire\/emergency_management\/tsunami_preparedness.php\" target=\"_blank\" data-cms-ai=\"0\" rel=\"noopener\">Huntington Beach<\/a>, <a class=\"Link\" href=\"https:\/\/www.newportbeachca.gov\/how-do-i\/find\/disaster-preparedness-information\/emergency-notification-systems\" target=\"_blank\" data-cms-ai=\"0\" rel=\"noopener\">Newport Beach<\/a> and <a class=\"Link\" href=\"https:\/\/www.lagunabeachcity.net\/live-here\/emergency-management\/alert-and-warning-system\" target=\"_blank\" data-cms-ai=\"0\" rel=\"noopener\">Laguna Beach<\/a> all have audible outdoor siren systems. Torrance <a class=\"Link\" href=\"https:\/\/www.torranceca.gov\/government\/city-manager\/torrancealerts\/torrancenow\" target=\"_blank\" data-cms-ai=\"0\" rel=\"noopener\">also uses sirens for emergencies<\/a>, including for leaks or explosions at nearby oil refineries. The decommissioned San Onofre nuclear plant once had sirens to warn of a meltdown.<\/p>\n<p>When it comes to fire, more cities are considering sirens \u2013 if they can fund it. Beverly Hills, for example, <a class=\"Link\" href=\"https:\/\/www.beverlyhills.org\/623\/Outdoor-Warning-Siren-Project\" target=\"_blank\" data-cms-ai=\"0\" rel=\"noopener\">installed a network of 12 sirens<\/a> after destructive fires across the state in 2018 and 2019.<\/p>\n<\/li>\n<\/ul>\n<p>Sirens in an age of worsening wildfire<\/p>\n<p>As wildfires grow hotter and more destructive, and the limits of cellphone alerts continue to be revealed, many communities are reconsidering sirens.<\/p>\n<p>Take, for example, Paradise in Northern California\u2019s Butte County. In 2018, the Camp Fire razed the town, killing at least 85 people. At the time, Paradise had the <a class=\"Link\" href=\"https:\/\/codered.crisis24.com\/resident-faq\" target=\"_blank\" data-cms-ai=\"0\" rel=\"noopener\">CodeRED<\/a> phone alert system (and still does), but that fire led to cell service going out, and many people said they didn\u2019t receive alerts.<\/p>\n<p>The community is still recovering today. As part of that recovery, Paradise decided to invest in 21 sirens, which, nearly seven years later, are up and running.<\/p>\n<p> An outdoor warning siren in Paradise, Calif.<\/p>\n<p>The new warning sirens in Paradise can be disguised as trees. <\/p>\n<p>The sirens sound up to 90 decibels and can be operated manually via internet or satellite. They\u2019re hardwired to power underground, but also have solar and battery backup power.<\/p>\n<p>But they are really only audible outside, and the ability to hear them can decrease dramatically just a slight distance away, said Mayor Steve Crowder, who lives about a quarter mile from one siren and couldn\u2019t hear it well from inside his house during tests.<\/p>\n<p>\u201cPeople were looking to be able to hear them from inside, with windows closed and not all of them have hit that mark,\u201d he said.<\/p>\n<p>To solve for that, the town got additional funding to purchase transmitters that can be placed inside residents\u2019 homes. If the sirens go off, those will too. Paradise plans to distribute them this year, Crowder said.<\/p>\n<p>\u201cIt&#8217;s not going to be a cure all, but it&#8217;s sure going to make it a lot more efficient and I think make everybody a lot safer,\u201d Crowder said.<\/p>\n<p>But the cost is high: The sirens were a little over $3 million, funded by a Federal Emergency Management Agency grant. The town found additional funding for the transmitters.<\/p>\n<p>The rest of Butte County decided to go another route \u2014 a technology called <a class=\"Link\" href=\"https:\/\/alertfm.com\/\" target=\"_blank\" data-cms-ai=\"0\" rel=\"noopener\">AlertFM,<\/a> which uses FM radio signals instead of cell service. (The county also still uses CodeRED mobile alerts \u2014 redundancy is key in emergency planning, experts say).<\/p>\n<p>    <img decoding=\"async\" class=\"Image\" alt=\"A white rectangular radio receiver reading ALERT FM in black lettering.

People can also buy their own for about $100.<\/p>\n<p>\u201c\u200aA majority of the citizens, the sheriff and the board felt that AlertFM was the best bang for the buck \u2014 of course, as long as people adopt them,\u201d said Butte County Supervisor Doug Teeter.<\/p>\n<p>That technology has similar limits as cellphones and sirens \u2014 FM signals can be blocked by terrain.<\/p>\n<p>\u201c\u200aHow do you reach folks that don&#8217;t have their cellphone? That&#8217;s the purpose of the sirens and AlertFM,\u201d Teeter said. \u201cI don&#8217;t think there&#8217;s going to be a perfect solution. It&#8217;s just a challenge that we face in trying to be able to reach everyone at a moment&#8217;s notice.\u201d<\/p>\n<p>It\u2019s why emergency experts say the most important thing is for individuals to be aware of their surroundings, have their own escape plan (and practice it), and expect that sufficient warning or help may not come in the case of a catastrophe.<\/p>\n<p>Why Malibu decided against sirens<\/p>\n<p>The city of Malibu also considered installing sirens after the 2018 Woolsey Fire. But <a class=\"Link\" href=\"https:\/\/www.malibucity.org\/DocumentCenter\/View\/26696\/City-of-Malibu-Siren-Feasibility-Final-Report---7232020\" target=\"_blank\" data-cms-ai=\"0\" rel=\"noopener\">a feasibility study<\/a> found residents couldn\u2019t hear them in high winds, hilly terrain and indoors.<\/p>\n<p>The 20- to 30-foot towers can also be an eyesore, and the cost was estimated to be from $426,000 to nearly $2 million.<\/p>\n<p>\u201cThe problem we&#8217;re trying to solve for is how do we wake up people in the middle of the night when cell service is out,\u201d said Susan Due\u00f1as, \u200athe city\u2019s public safety director. \u201cDepending on the wind, the construction of your home, your hearing, all these factors, you may not hear it. So they are a very expensive investment for something that didn\u2019t look like it was going to solve the problem.\u201d<\/p>\n<p>    <img decoding=\"async\" class=\"Image\" alt=\"A graph showing three different types of outdoor warning sirens. \" data-image-size=\"articleImage\"  width=\"792\" height=\"416\" src=\"https:\/\/scpr.brightspotcdn.com\/dims4\/default\/5331567\/2147483647\/strip\/true\/crop\/1430x752+0+0\/resize\/792x416!\/quality\/90\/?url=http%3A%2F%2Fscpr-brightspot.s3.us-west-2.amazonaws.com%2F03%2F83%2Fd49c45aa4911b27b078be1032fe6%2Fscreenshot-2025-09-04-at-2-11-05-pm.png\" loading=\"lazy\" bad-src=\"data:image\/svg+xml;base64,PHN2ZyB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciIHZlcnNpb249IjEuMSIgaGVpZ2h0PSI0MTZweCIgd2lkdGg9Ijc5MnB4Ij48L3N2Zz4=\"\/><\/p>\n<p>The types of warning sirens can vary. But terrain and modern building standards can mean that they are difficult to hear indoors.<\/p>\n<p>(<\/p>\n<p>Malibu Siren Feasibility report<\/p>\n<p>)<\/p>\n<p>The city also considered AlertFM, but that came with its own set of challenges and an upfront cost for a five-year licensing agreement of $960,000. And the main radio station in the area, KBUU, had too weak of a signal to reach most of Malibu\u2019s residents. So the city invested in the station, installing a booster antenna last year.<\/p>\n<p>\u201cThe coverage is better, but people aren&#8217;t able to hear it in their homes, so that&#8217;s a problem,\u201d Due\u00f1as said. \u201cThe signal&#8217;s not strong enough to get into somebody&#8217;s home.\u201d<\/p>\n<p>That\u2019s why the city is currently surveying residents about AlertFM reception. The city of L.A. is also giving Malibu two mobile speaker trailers. L.A. purchased six through a federal grant.<\/p>\n<p>But none of this is meant to replace cellphone alerts, home hardening or plain old preparation and awareness, Due\u00f1as said.<\/p>\n<p>\u201cWe wish there was a magic answer that would just solve the problem.
