Gragraph home seismograph for earthquake safety
Written by: Michael Keferl on September 28, 2007 at 5:16 pm | In Technology & Gadget Trends |For those of you in earthquake prone areas (or in the general vicinity of Asashoryu), you probably feel tremors quite often, but don’t really know how they register. The Gragraph home seismograph is a new way to chart basic seismic data at home, keep records of it, and also increase safety.

When an earthquake is happening, the Gragraph emits an alarm that grabs your attention, states the intensity, and then recommends precautions (duck and cover) based on the strength. Its calendar function stores previous events and times for your reference as well.
While we’re sure these won’t become as common as smoke alarms, many Japanese are certainly worried about The Big One that is “coming soon”, and take other precautions such as safety lights and emergency water. Safety in general is a major industry in Japan in many areas, particularly when it comes to earthquakes.

I would like a sensor that I can place on buildings to detect earth tremors. I also want a sensor to measure widening cracks on buildings and give me a data printout or record. I would like to place these sensors on buildings and leave them there to monitor the movement and the cracks. Can you help me? Thanks

[...] Considering the general threat of impending earthquake that pervades Japan, we’re surprised that we don’t come across more seismic-themed gadgets, despite the presence of more basic devices like the Gragraph. [...]
