  • Quake retrofit program could create more housing in ...

    Jul 23, 2019 · One way to soften the financial hit is to allow property owners to build more housing: Rather than just retrofit the ground floor for earthquake safety, landlords could convert what's often tuck-under parking and storage space into new housing units, bringing the building into compliance while adding to their rental revenue.

  • Pre-earthquake ionospheric anomalies registered by ...

    Abstract. In this paper we examine pre-earthquake iono-spheric anomalies by the total electron content (TEC) de-rived from a ground-based receiver of the Global Posi-tioning System (GPS). A 15-day running median of the TEC and the associated inter-quartile range (IQR) are uti-lized as a reference for identifying abnormal signals dur-

    Ground shaking is the primary cause of earthquake damage to man-made structures. When the ground shakes strongly, buildings can be damaged or destroyed and their occupants may be injured or killed. Seismologists have observed that some districts tend to repeatedly experience stronger .

  • STEC Equipment: Ground Quake Sand Injector : Golfdom

    Aug 05, 2014 · The Ground Quake Sand Injector is capable of performing both decompaction and sand-slitting in a single pass. With three 10-inch-long blades per flange, working on 10-inch centers, this machine quakes the ground from side to side as the blades rotate, which results in optimal decompaction by laterally fracturing the soil profile while also backfilling the trench.
