Minor tremor jolts Ctg
Staff Correspondent
A minor tremor jolted Chittagong yesterday, according to the Bangladesh Meteorological Department, a week after an earthquake-triggered Tsunami devastated several south and southeast Asian countries.But there have been no reports of causalities or damage resulting from the tremor. The country's lone seismic observatory in Chittagong recorded the magnitude of the quake at 3.56 on the Richter scale at 44 seconds past 12:32 p.m. yesterday, with its epicentre some 101 kilometres away, said an on-duty meteorologist at the met office seeking anonymity. The shock lasted for 12 seconds, he said. "With the lone observatory station, we can at best determine the distance of the quake's epicentre but we need at least three observatories to determine the direction or the location of the epicentre," he said. Asked whether the tremor has any correlation with the Sumatra quake of December 26, the meteorologist said it is very difficult to determine. Samarendra Karmaker, another quake expert and deputy director of the met office, said the two quakes are unrelated. "The tremor is unlikely to have a correlation with the devastating Tsunami, as the latter occurred several days ago," he said. A number of tremors may occur before and after a severe earthquake, but it is difficult to ascertain whether the present one has any correlation with the recent Tsunami, said another deputy director of the met office seeking anonymity. He added the yesterday's earthquake might have been caused by any of number of geological factors.
