Tsunami alert systems – nothing can happen without sirens
When a tsunami reaches the coast, it generally causes a major loss of life, devastates the infrastructure and tourists tend to stay away from the region for many years to come. As well as grief and tragedy, the population has to face the immense task of rebuilding an inhabitable environment. This is associated with enormous private and government investment. It is often many years before regions affected by tsunamis are able to resume a relatively normal way of living.
Tsunamis cannot be prevented. Affected regions are under constant threat. Tsunamis are fast – they often hit the coast unexpectedly very soon after an earthquake has been registered in the ocean. Time is of the essence when a tsunami is about to hit. They are at their most destructive when there is not enough time for evacuation and escape.
Tsunami alert systems help to keep the loss of human life as low as possible. They detect impending earthquakes and send out warnings before a tsunami is triggered. No time is wasted. The civilian warning prior to a tsunami is sent out across various media. Sirens are an important aspect of the so-called “last mile”. They do not need to be actively enabled by civilians, work independently of the power supply, the internet or GSM network, and send out high-volume warnings within seconds. A siren can be heard everywhere, even on the beach, in the water, in the most provincial hut or on a boat close to the shore. An expertly designed siren warning system allows individual sirens to be selected and alarms to be triggered in a matter of seconds.
