Oceanic earthquake and tsunami real-time monitoring system

The invention discloses an oceanic earthquake and tsunami real-time monitoring system. The oceanic earthquake and tsunami real-time monitoring system comprises an earthquake water level monitoring instrument which is arranged on a seabed and a floater which is arranged on the sea surface, wherein the earthquake water level monitoring instrument comprises a pressure-resistant ball and a base whichis fixedly arranged at the bottom of the pressure-resistant ball; a control storage module, a signal processing device and a battery pack are arranged inside the pressure-resistant ball; a first soundcommunication device connected with the storage module, as well as a pressure sensor and a hydrophone connected with the signal processing device are fixedly arranged outside the pressure-resistant ball; the base is provided with a microorganism generation device which is connected with the battery pack inside the pressure-resistant ball; and the floater is used for receiving an acoustic signal of the earthquake water lev
