Researchers have created a new tsunami detection system that could save a lot of lives.\u00a0<\/p>\n

Scientists at Cardiff University<\/a> in Wales, United Kingdom, have developed a technology<\/a> that utilizes underwater sound waves to provide real-time warnings of a tsunami.<\/p>\n

The new system, Global Real-time Early Assessment of Tsunamis (GREAT), detects sound waves using underwater microphones called hydrophones.\u00a0<\/p>\n

GREAT can also capture the properties of tsunamis from non-seismic sources because they also generate acoustic gravity waves.<\/p>\n

This will be important when a tsunami, or something resembling a tsunami, is caused by extreme weather<\/a>, which is becoming more common<\/a> due to the overheating<\/a> of the planet.<\/p>\n

“The technology<\/a> runs in real-time, without relying on pre-set templates or assumptions, and has been tested successfully using real hydrophone data,” said<\/a> project lead Dr. Usama Kadri.<\/p>\n

Current forms of detection, like DART, are based on sea-level sensors and only detect tsunamis after they’ve already arrived. They’re slow to warn and leave little time to respond, especially if an area is close to the source.\u00a0<\/p>\n

The deadly 2004 tsunami in Thailand, in which the waves arrived just 14 minutes after an earthquake and killed nearly 230,000 people<\/a>, is an example of this.<\/p>\n

Traditional forms of detection can also create false alarms<\/a>, which can lead to mistrust in the warning system and potentially unnecessary deaths. On top of that, they’re incapable of assessing the size of a tsunami or if one is generated from non-seismic sources.<\/p>\n

The GREAT project has been underway for years, beginning in 2013<\/a>, and it’s scheduled to be completed in 2030.<\/p>\n

The biggest issue the GREAT system is facing is a lack of hydroacoustic stations. There are only 11 stations globally<\/a>, and only four of those provide real-time data. Only tsunamis within a certain range of those four stations will be picked up.<\/p>\n

“Provided an event is within a thousand kilometers (about 621 miles) from a hydrophone station, it will take on average, six minutes for an end-to-end assessment,” Dr. Kadri said<\/a>. “The analysis itself takes only a few seconds on a standard PC station.”<\/p>\n
