We don’t need ‘The Rock’ to save the day, we just need to ‘Get Social’!

Mobile applications and sensors are commonly used to monitor traffic, health & wellness and incidents such as road traffic accidents.  But what about the threat of catastrophic disasters such as earthquakes where the loss of life can be unprecedented?

The sun drenched, Californian city of Pasadena is known for hosting the annual Rose Bowl Football game.  It is also located near the infamous San Andreas Fault (SAF).  If you paid attention in geography class at school or if you’ve seen the latest Hollywood blockbuster, ‘San Andreas’  starring ‘The Rock’, you’ll know that this means the city is at risk from earthquakes.

Can ‘The Rock’ save the day?

It is suspected that one day California will be hit by The ‘Big One’.  This is a hypothetical earthquake of a magnitude ~8 or greater that is expected to happen along the SAF. Such an earthquake will result in devastation to human civilization within about 50-100 miles of the fault in urban areas such as Palm Springs, Los Angeles and San Francisco. No one knows when ‘The Big One’ will happen because scientists cannot predict earthquakes with any precision.  However, technology is providing them with data that in time will give Californian residents a fighting chance of survival.

Seismometers are highly sensitive instruments that detect seismic activity that occur before earthquakes strike. Unfortunately, due to their cost, the number of seismometers in California are limited.  The Southern California Seismic Network operates just 350 seismic stations and the Northern California Seismic Network has a further 412.

With the threat of ‘The Big One’ forever looming, The Caltec Institute in Pasedena embarked on a project to determine how they could provide a blanket of cheap Seismometers across the state.

Their answer? Smartphones! Yes, really!

Research conducted proved that accelerometers found in most smartphones are sensitive enough to detect large earthquakes.

Creating the ‘Community Seismic Network’ – Caltech is encouraging residents to opt-in to turn their smart phones into mobile seismometers by simply downloading an application called ‘Crowdshake’ onto their android device.

Caltec have said: “if only 1 percent of users in the area opted into the scheme, that few hundred seismometers would be augmented by several hundred thousand additional sensors giving sufficient intelligent processing”.

So how does it work?

Upon downloading the mobile application an algorithm executes in the background of the mobile device.  Algorithms are monitored and when seismic motion is detected by the accelerometer, a message is sent to a Cloud Fusion Center which includes the time, location, and estimated amplitude of the data that triggered the message.

The benefit of the Community Seismic Network is huge.  A dense, city-wide seismic network could be used to detect earthquakes rapidly after they start and measure the strength of shaking accurately as it unfolds.

What would this mean to Californian residents? Well, it will enable immediate action to be taken to prevent damage, such as stopping trains and elevators, stabilizing the power grid, and deploying emergency teams.

This is an astounding example of the Internet of Everything! People, data, process and things coming together to save lives in real-time!

Whilst the application is currently a research prototype and not yet fully deployed for public use, Caltech anticipate that the capability of real-time early warning may convince users to download and install the application when it is readily available.

So quite simply, it pays to ‘get social’ especially on those days when ‘The Rock’ isn’t around the save the day!

Open Source at The Large Hadron Collider and Data Gravity

I am delighted to announce a new Open Source cybergrant awarded to the Caltech team developing the ANSE project at the Large Hadron Collider. The project team lead by Caltech Professor Harvey Newman will be further developing the world’s fastest data forwarding network with Open Daylight. The LHC experiment is a collaboration of world’s top Universities and research institutions, the network is designed and developed by the California Institute of Technology High Energy Physics department in partnership with CERN and the scientists in search of the Higgs boson, adding new dimensions to the meaning of “big data analytics”, the same project team that basically set most if not all world records in data forwarding speeds over the last decade, and quickly approaching the remarkable 1 Tbps milestone.

Unique in its nature and remarkable in its discovery, the LHC experiment and its search for the elusive particle, the very thing that imparts mass to observable matter, is not only stretching the bleeding edge of physics, but makes the observation that data behaves as if it has gravity too. With the exponential rise in data (2 billion billion bytes per day and growing!), services and applications are drawn to “it”. Moving data around is neither cheap nor trivial. Though advances in network bandwidth are in fact observed to be exponential (Nielsen’s Law), advances in compute are even faster (Moore’s Law), and storage even more.  Thus, the impedance mismatch between them, forces us to feel and deal with the rising force of data gravity, a natural consequence of the laws of physics. Since not all data can be moved to the applications nor moved to core nor captured in the cloud, the applications will be drawn to it, a great opportunity for Fog computing, the natural evolution from cloud and into the Internet of Things.

Congratulations to the Caltech physicists, mathematicians and computer scientists working on this exciting project. We look forward to learning from them and their remarkable contribution flowing in Open Source made possible with this cybergrant so that everyone can benefit from it, not just the elusive search for gravity and dark matter. After all, there was a method to the madness of picking such elements for Open Daylight as Hydrogen and Helium. I wander what comes next…
