A radar-based early tsunami warning system is currently being installed in three central locations along Israel's Coastal Plain—in Haifa, Ashdod and Hadera—dispersed so as to cover the entirety of Israel's Mediterranean coastal strip.
By connecting into the system, Israel joins a number of southern European and Mediterranean Basin countries, including Lebanon and Turkey, to place the tsunami warning system on their territory.
The system is interlinked with its "sister stations," ranging from Portugal in the west to Ashdod, the system's farthest southeastern point—as North African countries have yet to install it.
The warning system is capable of locating suspicious seawater activity such as exceedingly high waves or irregular tides and issue a preemptive warning in time periods of up to an hour.
Within several months' time, the system will also be connected to Home Front Command's siren system, which will then be able to blare an alarm of an impending tsunami hitting Israel.
In such an eventuality, residents will be required to immediately move away from coasts and beaches, whereas people residing on the shoreline will be asked to seek higher ground or flee eastwards.
"Earthquakes similar to ones that have already hit Greece and its islands may trigger tsunami waves in our direction," a senior defense establishment official explained to Ynet.
"Tsunami protection is also important considering the power stations situated near the waterline, such as Tel Aviv's Reading Station and Rutenberg near Ashkelon, as well as water desalinization plants that may be damaged if no early warning is received," he said.
The project is being spearheaded by the European Union, and a representative on its behalf will be dispatched to Israel to supervise and assist in the system's installation.
The official further added that the "Truah" project is simultaneously going forward full steam ahead, concerning deployment of sensors on Israel's eastern frontier, running north to south, in a region adjacent to the Great Rift Valley.
The system's 120 sensors will be able to produce an earthquake warning at extremely short notice, of several seconds up to several minutes, depending on the location of the earthquake's epicenter. The system's installation will conclude and it will be declared operational by 2019.
Signs posted along beaches
While the system is being set up in Haifa, the city's municipality put up signs on beaches directing visitors to safe places in case of tsunami. Explanation leaflets outlining the phenomenon's attendant risks will also be disseminated.
The National Emergency Management Authority (NEMA)—the agency parallel to the American Federal Emergency Management Agency—said the Mediterranean was one of the world's most vulnerable regions when it came to tsunamis.
Some 25 percent of all documented instances of tsunamis hitting took place in the Mediterranean, the Authority added. "Every 100 years on average a significant tsunami hits the eastern Mediterranean," an official added. "Every 250 years on average a tsunami hits Israel's coast and every 700 years on average a devastating tsunami hits."
The director of the interministerial steering committee on earthquake preparedness, Amir Yahav, said that Israel received tsunami warnings from international warning hubs spread out across the Mediterranean Basin. "The last tsunami warning was received in Israel in July 2017, after an earthquake near the Greek island of Kos," he elucidated.
Dr. Beverly Goodman-Tchernov, a tsunami specialist from Haifa University's Department of Marine Geosciences, explained, "Israel, as well as some portions of the Mediterranean and especially the Middle East, has a history of tsunamis. The region has all the requisite ingredients: tectonics, earthquakes and a sea."
Dr. Goodman-Tchernov added that a minor tsunami hit Israel in 1956, but caused no damage. "If you're looking for something that did damage, you have to go back something like 800 years," she said.
