Refraction Microtremor (ReMi) Technique

ReMi Data Acquisition

Data acquisition and analysis takes about three hours
No physical restrictions beyond required line deployment space, minimal permitting
Data can be acquired along roads, in buildings & at active construction sites
No specialized recording equipment required
Standard refraction seismograph & refraction P-wave geophones
No artificial seismic source Uses ambient noise: “Quiet” site not required
Can be used offshore as effectively as on-shore
