Can Phone Call/Text Traffic Help Identify Emergencies?

This article describes an Israeli study which tried to find the existence of emergencies based on spikes in telephone and text traffic.  The idea goes like this:

  • Identify high traffic nodes, essentially people who make lots of calls and text messaging (the data was all anonymized to avoid identifying actual people);
  • Take non-random samples of call and text traffic at these high traffic nodes;
  • Spikes in traffic, amplified by a fancy algorithm, suggest the presence of a big event.

To quote the article:

The researchers applied an algorithm they call the Social Amplifier to this nonrandom sample to tease out where and when emergency events could be found. Those uncovered included eight real emergencies—three storms, a bombing, an earthquake, a blackout, and two airplane-related events—as well as eight other big local happenings, such as concerts and festivals, that were not emergencies.

Can such an approach be done here in the US?  We wonder if the public would believe that the use of cell phone data – especially data based on identifying heavy callers – was really anonymous.  And since the approach appears to identify many events with big social impact – not just emergencies – it’s really only valuable as a supplemental data source.

Still, in a world that is being rapidly shaped by the use of “big data”, it’s an interesting and potentially useful idea.

Why So Few Downloads for Emergency Alert Apps?

Hyper-Reach offers an emergency alert app for smartphones, as do several of our competitors. We think ours is pretty cool and has some neat features you won’t see on other apps.

But we need to be humble.  As does everyone who’s created an emergency alert app for smartphones.  Because the simple truth is that these things are not getting much attention from the public.  As best we can tell, none of the apps provided by any mass emergency notification provider have reached even 1% of their target audience.

When we search for emergency alert apps on the iPhone and Google Play stores, a few potential reasons become obvious:

  1. Fragmentation.  Search for “emergency alerts” and hundreds of apps come up on the Google Play site with no good way to filter through them.  They include apps for specific places (Alaska, Alberta, etc.) and apps that are to sound the alert instead of receiving one.  For many folks, that’s enough to stop a search altogether.
  2. Confusion.  Hand-in-hand with fragmentation is confusion.  Why install an app for emergency weather alerts if I can get weather alerts for free from another, non-emergency app?  Where’s the value?  It’s just not clear.
  3. More confusion.  One of our biggest competitors shares its name with a lot of unrelated apps.  Type “codered” into Google Play and you’ll see apps to “insert code into your brain” and track female menstrual cycles, among other things.
  4. Poor reviews.  Some of the apps we consider most relevant to mass emergency notification have pretty weak ratings.  3+ out of 5 is not strong and will turn off many potential users. (Our rating is 4+, BTW.)
  5. Cost.  Some apps charge money, while others are free.  Why pay for weather alerts if I can get them free from or my local news station?

We’ve got ideas about how to fix this, or at least make the situation better.  But it’s going to take work.  And we’d love to share your thoughts.

What Role for Emergency Alerts with Ebola?

Now that we have the first case of a patient being diagnosed with Ebola in the US, it’s worth asking whether emergency alerts can play a role in helping deal with this disease, either in Dallas, where this particular patient is located, or in some other city, which could have another case.

Dallas is special because one of the two Americans flown back from Liberia with Ebola was from Dallas, so news reports suggest that there’s already a high awareness of the disease in that area.

It seem to us that emergency alerts can potentially help in a few different ways:

  1. Calm fears with education.  An epidemic of Ebola is highly unlikely in the US.   But that doesn’t mean the public understands this.  One poll found that one in four Americans are worried they or a family member will get the disease.  Alerts could help direct folks to information that could allay their concerns.
  2. Direct citizens to health care.  Getting someone with Ebola into the health care system is critical in stopping its spread.  This is one of the reasons the disease has gotten out of hand in African countries, where people have avoided health care workers.  Telling folks to report their symptoms – especially if they’ve been exposed to someone who’s been to Africa – might be helpful in getting them into the health care system sooner.
  3. Mobilize public safety and health care workers.  One of the surprising things about the Dallas case is that the patient went to the hospital and was sent home and was not then diagnosed until going back to the hospital a few days later.  It turns out that the nurse asked the patient, but somehow the information didn’t get to whoever made the discharge decision.  Asking someone with a fever if they’ve been to Africa within the past month or exposed to someone who has seems like a pretty simple question and one that should focus attention well.  Reminding staff to pass the information makes sense. And since the incidence level of the disease is going to be very small, reminders using the alert system could be helpful in making sure that question gets asked and the information shared.  Many hospitals use systems such as Hyper-Reach and many public safety agencies use their alert systems both for staff communication as well as public alerts.

There may be other roles that emergency alert systems like Hyper-Reach can play.  If you have any thoughts, feel free to suggest them.  We’d love to hear from you.


Are Government Mandates the Solution to Alert Registration?

Local officials in Kennett Square, PA have a new idea for how to solve the problem of folks not registered for emergency alerts.  They’re suggesting that registration be mandated by law.

According to this article, the borough council president there  is proposing that “officials mandate all residents of the borough sign up for emergency notifications”.  It’s an interesting idea, but it raises a lot of issues.  For example:

1) Privacy.  Many folks will object to requiring giving up the personal information.  That concern is probably overblown, but it’s a political problem. 

2) Enforcement.  How will officials know if someone is NOT registered?  Homeowners may be easy to find, but most municipalities don’t have a list of non-homeowners they can easily turn to.

3) Garbage data.  If someone wants to stay off the radar, they could register a bogus number.  They’d show up as “registered”, but with no beneficial effect.

4) Language issues.  According to Wikipedia, about 40% of the town is hispanic, but the registration form is only available in English.

This requirement is somewhat similar to that of the requirement for smoke and CO2 detectors, but there are some important differences.  For one, the building inspection process means that homes will be checked when they are sold.  And landlords might be responsible for insuring detectors in apartments.

We think it’s fantastic that a town cares enough that it would want to require folks to sign up for emergency alerts.  But perhaps local officials should start with a registration campaign – in English and in Spanish – and use a government mandate as a last resort.



Barrier Islands – A Growing Threat for Emergency Managers?

This article in the NY Times talks about the growing risks for barrier islands on the Atlantic and Gulf Coasts of the US.

It seems that two trends are coming together to pose unusually high risks:

  1. Global warming and the resulting increase in sea levels are increasing the dangers to folks living on those islands;
  2. Population growth on these islands is very strong: twice the US average.

Those trends got us thinking about the importance of good emergency planning, which has always been important in coastal communities facing hurricanes, tornadoes and other natural disasters.

Barrier islands are a special case because they are difficult to evacuate.  The road system on these islands is often a great example of a “single point of failure”, where the loss of one road cuts off all transportation options.  And storm surges and other forces can often easily take out roads.

This makes emergency alert services especially important, since getting the word out to evacuate is a critical part of any emergency plan.  So if you have doubts about the reliability of your alert system, you should give Hyper-Reach a call.

Shellshock – We’re Patched and Ready to Do More

If you haven’t heard of Shellshock and rely on web-based services, you need to be aware.  And make sure the folks who run your services are on top of this issue.

As reported by the Washington Post:

The National Institute of Standards and Technology’s National Vulnerability Database scored the vulnerability as a “10,” on a scale from one to 1o, on both impacts and exploitability. US-CERT also issued an advisory, saying “exploitation of this vulnerability may allow a remote attacker to execute arbitrary code on an affected system.”

That means that someone could remotely take over a server.

From the perspective of mass emergency alert providers, that could mean serious trouble.  We should all remember the incident last year when the emergency alert system at a Great Falls, MT television station was hacked and sent out bogus warnings that “dead bodies are rising from their graves”.  So a hacker could potentially take over some other emergency alert service to send out similar warnings – or worse.

All the major emergency alert service providers (CodeRed, Everbridge, Hyper-Reach, etc.) use web-based services to enable their clients to send out alerts.  Unless the servers that provide the web interface are protected from hackers, there’s a serious risk.

If you use Hyper-Reach, you’re protected by an IT team that takes security seriously.  Our servers were patched within hours of the news of this vulnerability.  And we’re tracking the issue closely, which is important, since there have been at least three new bash-related vulnerabilities reported.

If you don’t use Hyper-Reach for emergency alerts, check with your vendor.  It’s important.  And if you use other web-based services, you should check with them as well.

Wireless Emergency Alerts and local emergency alerts: what FEMA says.

FEMA’s website has a page on Wireless Emergency Alerts – the text alert part of the IPAWS system, which includes an FAQ section.  Here’s the Q&A on how WEA relates to local emergency alert services, such as Hyper-Reach:

Is this the same service public safety agencies have asked the public to register for?
No, but they are complementary. Local agencies may have asked you to sign up to receive telephone calls, text messages, or emails. Those messages often include specific details about a critical event. WEAs are very short messages designed to get your attention in a critical situation. They may not give all the details you receive from other notification services.

This explanation is fine as far as it goes, but it doesn’t make it clear how different local alerts are from WEA messages.  Boil water alerts, for example, which are a large part of local alert messaging (there are over 800 water main breaks in the US each day), probably wouldn’t qualify or be used for IPAWS.  So in addition to the level of detail, there’s a big difference in the subject matter of WEA and local alerts.

WEA is clearly useful, but also clearly no substitute for local alerts.  We wish FEMA had done more to encourage folks to sign up for their local alert systems.

RecordTime™ – Send a Real Voice Message ASAP!

Of all the features that Hyper-Reach offers, we really like RecordTime, which enables you to record a voice message directly on your PC or laptop.

Before RecordTime, our customers had to go through a tedious procedure of recording their message by either calling it in or recording it using another application.   Then, they’d need to transfer the recording to the system for sending out to the public.

Now, with RecordTime, recording a voice message on your PC is as simple as clicking a button and talking into your PC-connected microphone.  The message is recorded directly within the Hyper-Reach system, so there’s no need to transfer files anywhere.  And because RecordTime uses your PC microphone instead of the telephone, the clarity is as good as it gets.

If you’re a Hyper-Reach client and haven’t tried RecordTime, give it a try.  And if you need help, just let your account executive know.

IPAWS/WEA and Hyper-Reach Aid Wildfire Evacuation

As many people saw, Washington State was ravaged by wildfires in July, destroying hundreds of thousands of acres of forest. Officials estimate the damage at six times the average annual area normally damaged by wildfire.

Stevens County – a Hyper-Reach client – was spared fatalities, in part, thanks to an effective evacuation campaign, aided by the new FEMA Wireless Emergency Alert (WEA) system, which is part FEMA’s IPAWS system.

The fire was the first time Stevens County public safety officials have used the Wireless Emergency Alert system, in addition to phone calls and texts sent by Hyper-Reach.  One advantage of the WEA system is that it reaches “wireless-only” households, where more than 40% of Washington State residents live. 

The Hyper-Reach system enables public safety personnel to send WEA and other emergency alerts through the same standardized interface.  To find out more about how Hyper-Reach can enable emergency officials to access IPAWS, go to

“Wireless-Only” Reaches 43% of Households

Venn bubbleThe Centers for Disease Control publish statistics twice a year showing the percentage of households that have landlines or mobile phones or both. 

It’s an impressive study, with a huge sample.  But because it comes out six months after the data, we’ve developed a model to project where the US really is in terms of “wireless substitution” as they like to call it.

Based on the most recent data, we’re estimating that about 43% of all US households are “wireless-only”, meaning that they do not have a home landline.  So the only way you can reach them with a phone call or a text message is on their mobile phone.  And that’s for the US as a whole.  If you look at specific segments, such as the southern US, urban residents, younger people, etc., the wireless-only statistics are much higher.

By the end of the decade – maybe sooner – more than half the US will not be reachable via a landline telephone call.
