From the Krakatoa page:
"The third explosion has been reported as the loudest sound heard in historic times. The loudness of the blast heard 160 km (100 mi) from the volcano has been calculated to have been 180 dB. Each explosion was accompanied by tsunamis estimated to have been over 30 metres (98 feet) high in places. ...The energy released from the explosion has been estimated to be equal to about 200 megatonnes of TNT, roughly four times as powerful as the Tsar Bomba"
