Oman cannot ignore tsunami threat - expert

Muscat: Rumours about an impending tsunami may have died down, but the potential of the disaster
striking Oman's eastern coast from the Makran subduction zone cannot be ruled out, according to a
Canadian palaeontologist.

Eduard G. Reinhardt from School of Geography and Earth Sciences, McMaster University in Canada has
worked for several years in Oman's eastern coast near Qalhat and Sur on coastal evolution and ancient
harbours.

"He has found significant scientific evidence of the 1945 tsunami in Sur lagoon from shell deposits to raise
possibility of tsunami striking Oman in future," Dr Barry Jupp, senior marine scientist with the Ministry of
Regional Municipality, Environment and Water Resources, told Gulf News yesterday.

He added that there was hard evidence within living memory of a tsunami striking Oman's eastern side.
"It is not based on any hypothetical theory but hard evidence," he said, adding that the preliminary
studies were carried out from shell deposits in Khawr Al Batah.

According to Professor Reinhardt, fractured shells deposits found in the area indicate the impact of
tsunami or earthquake in the sea.

The history of 1945 tsunami, which seems difficult to find on official recorded data, also points at the risk
of tsunami from Makran subduction zone, where if more pressure on trenches builds up then it can release
pressure earthquake in water causing tsunami.

Dr Jupp reckons that the direct scientific evidence of tsunami makes Tsunami Early Warning system on the
Oman coast more relevant to assess the potential risk from the Makran subduction zone.

Prototype

In fact Texas-based Lighthouse Research and Development Enterprise has been trying out their Tsunami
Early Warning prototype system off Oman's coast and have found out that their new Dart system which
employs fibre optic cables is viable.

"We have set up our prototype system near Abu Bakara near Shinaz in the north of Oman after a two-year
agreement with Oman's Ministry of Agriculture and Fisheries' Marine and Science Centre," Ken Du Vall,
President and COO of Lighthouse, told Gulf News yesterday.

The system is called Lighthouse Environment Tsunami-Ocean Bottom Seismic (Let-OBS).

"Our system utilises latest advancement in telecommunication industry to bring seismic and wave height
information to monitoring facilities anywhere in the world and offers unprecedented reliability," he
claimed.

He said that they collect data from their system exclusive for Oman at the moment but they do have
permission from the Oman government to inform the world community about any imminent danger from
the data collect from this Tsunami Early Warning system here.

After initial experiments here, Du Vall, feels that the system has the potential to go Real Time and can
warn early about the impending tsunami.

Makran coast was hit by a magnitude 8 quake

- The tsunami of November 28, 1945 was a major incident in the region when an earthquake of magnitude
8 caused great devastation in the Makran area of Pakistan.

- More than 4,000 people were killed on the Makran Coast by both the earthquake and the tsunami. The
waves reached a height of over 10 metres in some Makran ports and caused great damage to the entire
coastal region, including the Omani coast.
