27
Q

Define Seismic Gap Theory

A

A segment of an active fault which has not ruptured recently (a seismic gap) has the greatest chance of rupturing in the future relative to other segments which have experienced large earthquakes

28
Q

When was Japan’s Earthquake Early Warning (EEW) system launched?

A

2007

29
Q

What early warning system does Japan use?

A

A P-wave system which includes >1,000 seismometers and a network of intensity metres

30
Q

What does Japan’s early warning P-wave system calculate?

A

The earthquakes epicentre location and magnitude, as well as predicting the damage radius and maximum expected seismic intensities at each affected region

31
Q

What does the Deep-ocean Assessment and Reporting of Tsunami (DART) do?

A

Bottom pressure sensors on buoys constantly measure the pressure of the overlying water column

32
Q

What will the JMA (Japanese Meteorological Agency) do if two or more P-waves are detected on two or more seismographs?

A

Immediately analyse the readings and (before the arrival of the S-waves) distribute warning information to advanced users e.g. broadcasting and phone companies, enabling people to follow evacuation routes

33
Q

What else happens in Japan as part of their EEW system?

A

The Shinkansen Urgent Earthquake Detection and Alarm System (UrEDAS) to prevent the destruction of the bullet train, Smart meters to turn off gas and electricity
