Suddenly, spotlight on earthquake entrepreneur
Earthquake entrepreneur George Dickson hopes to change the way the world gets its earthquake warnings.

Some early detection systems gather data from sensors placed in various areas around an earthquake zone, compile it and then issue a warning for a region. The process can take as long as 30 seconds or more, Dickson said. QuakeGuard’s sensors (there are two per detection unit) are located on site – in schools, firehouses, commercial buildings – and set off alarms located at the same site.Skip to next paragraph

In other words, the time between detection and warning is minimal — as little as 400 milliseconds.
In a standalone deployment, the warning time is about one second for every 5 miles of distance to the hypocenter of the earthquake, according to SWS. This amount of warning can give automated systems plenty of time to respond and enough time for people to react.
Dickson said detecting the P-waves can give as much as a minute or more of warning time before a quake hits depending on the distance from the event. To prevent alarms from being set off by small quakes, the sensors only react to shock waves that indicate an earthquake of 5.0 or more on the Modified Mercalli Intensity (MMI) scale, which measures shaking severity.
SWS’s detection system is not just about giving people time to prepare prior to an imminent earthquake. Equally important is the system’s ability to communicate with other systems to prevent earthquake damage.
For example, a system installed in a firehouse may be designed to automatically open the firehouse doors at the first sign of an earthquake. This way, a damaged building, a lack of electricity or debris in front of the door will not prevent the firefighters from responding in an emergency. In another example, the system could be used to divert water or shut down sewage operations to prevent an infrastructure disaster.
SWS’s business model is currently undergoing a transformation. Whereas its initial focus was on selling its equipment and technology to customers including fire stations and schools, it is now working with schools, government agencies, NASA and others to create regional early detection coverage that would network its P-wave sensors together and allows them to communicate with each other to give even earlier warning to users.
The company is also working on shifting the way it brings its technology to customers. Until now, customers have purchased the sensor and the technology for their own use — at a cost of as much as $25,000 per system.
Going forward, SWS is working toward a subscription-based model where it will own the equipment and subscribers pay a much lower fee — around $1,200 — to receive the detection information from the QuakeGuard sensors.
“We’re transitioning from selling the system to setting up our own networks,” Dickson said. “We’re launching the next utility.”
The company is also transitioning away from self-financing and will soon begin seeking outside financing.
In the meantime, Dickson is hoping it won’t take another earthquake to keep his company in the public eye.
“We’re a business and we operate as such,” Dickson said. “But, we also care about providing a service that is good for people. Every second you have to prepare for an earthquake is a matter of life and death,” he said.
