On Monday, a strong 7.5 earthquake had frightened people in Papua New Guinea while authorized observers sent out a tsunami alert .
A magnitude of 7.7 was initially felt close to the town of Rabaul in Papua New Guinea where it is belived to be the epicenter of the earthquake , which is 787 kilometers north-east of the capital , Port Moresby, explained by the US Geological Survey. The depth was altered from 65 kilometers to 40 kilometers .
A report from Edward Leask who is a duty seismologist at Geoscience Australia stated that the first earthquake had hit at 10: 48 am Sydney time but there was no risk of a possible tsunami . He added that the earthquake below the sea was a bit stronger than ever and concluded that its strength was the greatest in the world this year.
Yet it has still substantially less strength than the 9.1 shake that had generated a tsunami during the Boxing Day in 2004.
Aftershocks were felt around the area a little after the pricipal earthquake, report said. Yet according to Mr Leask there was no actual indication that a tsunami wave might be triggered . But if there was a tsunami wave it would be difficult to foretell how much destruction it could possibly bring .
“Tsunamis are such tricky beasts,” Mr Leask said.
The cities that are vulnerable to earthquakes are Kokopo which has a population of 26,000 and Rabaul which has 8,00 .
An alert was released by the Pacific Tsunami Warning Centre in Hawaii for Papua New Guiinea and the Solomon Island. The alert stated “hazardous tsunami waves are possible for coasts located within 1000 kilometres of the earthquake epicentre along the coasts of Papua New Guinea and the Solomon Islands”.
There were no indications of destruction from the earthquake at Rabaul Airport and flight schedules resumed normally , a safety officer Joe Tamik stated by telephone.
