Provided is an earthquake response system using a seismic motion sensor. The seismic motion sensor of the earthquake response system includes: a sensor unit measuring a sensor value including peak ground acceleration (PGA) of the ground due to shaking; a seismic motion sensing unit sensing seismic motion on the basis of a seismic motion sensing result value calculated from an artificial neural network that uses the peak ground acceleration as input when the peak ground acceleration satisfies a seismic motion sensing condition; a seismic motion determiner determining generation of final seismic motion on the basis of a seismic motion determination parameter calculated from the sensor value on the basis of the seismic motion sensing result; a shaking grade calculator calculating a shaking grade of the determined final seismic motion through the peak ground acceleration; and a communication unit notifying the shaking grade of the final seismic motion.

Disclosed herein is a fluid collecting apparatus. The apparatus comprises a body disposed adjacent to fluid conveying or storing equipment to limit a moving path of fluid leaked from the equipment, a collector connected to the body to collect the leaked fluid, and a controller connected to the body to control an operation of the collector. The fluid collecting apparatus is capable of safely collecting fluid, for example, harmful gas leaked from fluid conveying or storing equipment.
