Theoretical predictions * and field surveys indicate that coastal run-up and inundation will be greater if the trough of the leading wave precedes the crest

Genesis Tsunami Coastal Alert Anchor Tsunami trough threshold level Receding sea trigger Anchor line under constant spring tension at buoy
Genesis Tsunami Coastal Alert Anchor Tsunami trough threshold level Tsunami trough (receding sea) Tension in anchor line pulls buoy into contact with trigger Flares ignited to signal coastal communities Satellite, RF, audible alarms execute responsive to contact with trigger
Genesis Tsunami Coastal Alert Buoy measures tsunami crest – broadcasts satellite data for emergency response in other areas.
Direct warning system in third world and emerging industrial countries
Local RF broadcast on emergency marine VHF channels and terrestrial radio
Can be activated in advance by RF or satellite transmission if deep sea sensors forecast tsunami hit in the area
Low Cost Design
No expensive off-shore installation and maintenance
Multi-use design – can be used for navigation, temperature readings, etc.
Ideal supplement to sophisticated deep sea monitoring
Genesis Tsunami Offshore Alert Responsive to seismic event GTOA releases non-buoyant pressure sensors at multiple depths below normal wave action. Genesis Offshore 02
Genesis Tsunami Offshore Alert Detachable pressure sensors Pressure changes below predetermined depth are indicators of tsunami activity. NOAA’s DART system uses pressure sensors that are permanently mounted to seabed. Prone to failure. Genesis Offshore 02
Genesis Tsunami Offshore Alert Detachable pressure sensors Pressure changes below predetermined depth are indicators of tsunami activity. Seismic event detected – Genesis Offshore buoys drop pressure sensors to multiple depths. Pressure Wave Genesis Offshore 02
Genesis Tsunami Offshore Alert Detachable pressure sensors Pressure changes below predetermined depth are indicators of tsunami activity. Pressure readings are relayed to monitoring station. Multiple readings provide more accurate analysis of deep pressure readings. Satellite Genesis Offshore 02
Genesis Drop Sensor Lead weight is adjusted so that rate of decent is controlled so that multiple sensors reach their operating depth in synchronization. Sensor is maintained above waterline before release. No fouling or damage from deep sea mounting. Pressure transducer supplied by Paroscientific, Inc. – Quartz crystal detection of flex of Bourdon tube. Telemetry and support line.
