Indonesian authorities lifted off double tsunami warnings Thursday after two more strong aftershocks rocked the Sumatran island, adding fresh fears among thousands of residents that stayed outdoors following the initial powerful tremblor the night before.
Officials at Jakarta's Meteorology and Geophysics Agency (BMG) said another 6.7-magnitude aftershock rattled Sumatra shortly before 9 am (0200 GMT), after an earlier 7.8-magnitude quake struck at 6:49 am (2349 GMT Wednesday).
Both aftershocks triggered government authorities to issue tsunami warnings, but they were lifted after no waves materialized, officials said.
The USGS said the first new quake on Thursday was centered about 200 kilometres from Bengkulu, a city on Sumatra. It occurred at a shallow depth of about 10 kilometres.
The Pacific Tsunami Warning Centre in Hawaii warned Thursday's quake had the potential to generate a destructive regional tsunami along coasts within 600 miles of the epicentre. It advised authorities to take immediate action to evacuate coastal areas.
Thursday's quake caused extensive damage in Padang, a local official said.
"Many buildings collapsed after this morning's quake," Fauzi Bahar, the mayor, told El Shinta radio. "We're still trying to find out about victims.
On Wednesday, a powerful 8.2-magnitude earthquake shook South-East Asia, collapsing buildings, killing at least five people and injuring dozens in Indonesia. That tremor triggered a small non-destructive tsunami off the coastal city of Padang on Sumatra, the Indonesian island ravaged by the 2004 tsunami disaster.
A tsunami warning was issued for wide areas of the region and nations as far away as Sri Lanka.
Officials said at least three people were killed in Bengkulu provincial capital from Wednesday's powerful quake, while more than a dozen were injured. dpa ff sh pw
Localización del terremoto.


De acuerdo al United States Geological Survey (USGS), un terremoto de 7,8 grados en la escala de Richter sacudió Indonesia a las 6:49 a.m. (hora local, 23:49 GMT). El epicentro del terremoto se localizó 185 kilómetro (115 millas) al sud-sudeste de Padang, Sumatra, con una profundidad de 10 km (6,2 millas).

Hace pocas horas, el 12 de septiembre, otro terremoto de 8,4 grados había sacudido la región matando a 6 e hiriendo cientos.

Varios post-temblores ocurrieron luego en el área, siendo el último de 7,1 grados con una profundidad de 10 km. Se reportó que había habido un post-temblor de 7,3.

La National Oceanic and Atmospheric Administration (NOAA) había declarado una alerta de tsunammi diciendo que el sismo tenía el potencial de "generar un tsunami destructivo local y a veces tsunamis destructores regionales en las costas localizadas a no más de mil kilómetros del epicentro del sismo", pero luego fue desechada ya que se reportó que no se habían originado tsunamis. Australia había sido incluida en la advertencia.

Un aviso fue enviado para el post-temblor de 6,5 grados diciendo que no había "una amenazada amplia de tsunami basada en los datos históricos del terremoto".

No se han declarado heridos, muertos o daños, pero la USGS declara que el daño podría ser de "moderado a grave". El sismo se sintió en Singapur donde se reportó los edificios que temblaron.
