Can history repeat itself?

The epicenter of the last earthquake that caused the massive Tsunami in December 2005, is again showing signs of severe seismic activities. According to geologists signs are building of a more massive underwater earthquake or volcanic explosion at that spot which can cause more severe Tusnami.

A nearby island of India experienced violent volcanic eruption. The dormant volcano erupted with lava flowing to the ocean.

A routine Coast Guard patrol on Saturday witnessed eruptions on Barren Island - a thickly vegetated, three-km-wide strip with a history of volcanic activity dating back to 1787. Inhabited mostly by rats, birds and feral goats, this island lies 135 km north-east of Port Blair on the inner arc extending between Sumatra and Myanmar.

“We spotted thick black smoke even 10 nautical miles away from the island,” S Basra, commander, Coast Guard (Andaman & Nicobar) told this website’s newspaper from Port Blair.
Lava from the 1.6 km-sized crater is reportedly ending up into the sea from the western side of the island. “When we landed, we saw red fireballs every few seconds and fresh lava on the ground,” says Basra. “In the past we have gone up to the crater. But this time it was so hot we could not go beyond 50 metres from the landing site.”

Indian Reconnaissance and Arial Survey planes had to maintain a height of at least 5000 feet flying over the island.

What was a sign of major concern for the Tsunami epicenter was the presence of strange staggering harmonic tremor on the ground all around Andaman and Nicobar islands.

“Barren Island is a northward extension of the Java-Sumatra volcanic belt. So violent eruptions are natural,” says volcanologist Chandrasekharam.

Some geologists are predicating for some times that the northern extension of the Java-Sumatra volcanic belt will be the cause of Tsunami soon in geological time scale.
