A steel ball 13 is magnetically held at an elevated position by a ring magnet 11, which is secured in place by a screw 12, which is held in place by a threaded hole 10A into the top cap 10, within the housing 15; in FIG. 2. In the event of a severe earthquake, the seismic vibrations will cause the steel ball 13 to shake and break away from the ring magnet 11. Gravity will cause the steel ball 13 to fall onto the slide trigger 14, it will be pushed down completely and the bottom portion of the slide trigger 14 shall make contact and engage a momentary switch 16; in FIG. 4. The momentary switch 16 will need to be connected to direct current. A transformer connected to an alternating current source. Or direct to batteries. Having both power sources will give redundancy to the apparatus in the event that there is a power outage during the earthquake. The momentary switch 16, in the engaged position will send voltage to a normally open motorized ball valve and cause it to close; FIG. 6. Preventing fluid to pass through said ball valve. Once the apparatus has been placed in the standby or ready state. In other words reset by manually pulling upward the lift handle 14A towards the top cap 10 in FIG. 3. The steel ball 13 will magnetically attract back to the ring magnet 11. The weight of the steel ball 13 and slide trigger 14 will be lifted off the momentary switch 16, causing the momentary switch 16 to disengage and the voltage will seize to power the normally open motorized ball valve, thus causing it to go back to its normally open state and allow the fluid to flow through. A preferred embodiment of the invention is that the parts 10, 14, 15, 17 be made of a non-magnetic substance so that those objects do not interfere with the ring magnet 11 and steel ball 13 in FIG. 2. The housing 15 must be mounted vertically such as in FIG. 1. Meaning the top cap 10 is above the housing 15. Therefore the bottom cap 17 will sit lower than the housing 15. The housing 15 should be made at an elongated distance to give chance for the steel ball 13 and slide trigger 14 to move freely in an upward and downward motion between the magnet 11 and the momentary switch 16. The slide trigger 14 should be installed loosely, so that it may move freely in an upward or downward motion, into the housing 15, followed by the lift handle 14A inserted into the slot for handle 15A and then the through hole 14B, using an adhesive compound to secure it in place with the slide trigger 14. Preventing it from coming apart and combining the two pieces as one, so that it will move as one piece in an upward or downward motion. The steel ball 13 is to be installed loosely, so that it may move freely in an upward or downward motion. The momentary switch 16 is to be installed into the center of the bottom cap 17 via a through hole 17A and be secured in place by a nut 18.
