We have farther discussed short term and imminent abnormality for borehole volume strain observation data before earthquake.

Short-impending anomaly of body-strain before two local earthquakes;

Initial observation data from Xichang strain observation station are processed and the strain short-impending anomaly information about the earthquakes are manifested.

<Abstrct> Through ascertaining and tracing the apparent resistivity trend anomaly in Mianning Station,combining with the ocurrence of geomagnetic Z component lower point displacement and diurnal morphological short-impending anomaly, applying geoelectic and geomagnetic precursor anomaly to decide the mark of earthquake s "3 elements", Lijiang M7.
