The location of creepmeter MEJ3 is situated 1.6 km south of Creepmeter MEJ2. The instrument was installed across the same active branch of the Mejillones Fault. It was installed directly in a paleoseismological trench where the location of the active branch could be well determined. Similar to the MEJ2 site multiple normal fault reactivation is documented in the trench. The active fault plane strikes 199° and dips 78° E.
