JAKARTA, Aug 19, 2020 (BSS/AFP) – Two large and shallow earthquakes struck
off Indonesia’s Sumatra island early Wednesday, the US Geological Survey
reported, but no tsunami warning was issued and there were no immediate
reports of casualties or major damage.
Frightened residents fled their homes when the twin offshore quakes rocked
Bengkulu city on Sumatra’s western coast, an AFP reporter said.
“The first earthquake was quick…but another one hit shortly after and it
was just as strong,” Bengkulu resident Jumentrio, who goes by one name, told
AFP.
“My children screamed hysterically.”
The area was hit by a string of aftershocks, according to Indonesia’s
Meteorology, Climatology and Geophysics Agency.
“But until now we haven’t received any report of damages due to the
earthquakes,” said Rahmat Triyono, head of the agency’s tsunami and
earthquake centre.
The quakes, of magnitude 6.8 and 6.9, struck within six minutes of one
another from 5:23 am (22:23 GMT Tuesday) at a depth of between 22 and 26
kilometres, respectively.
Shallower quakes tend to cause more damage than deeper ones.
But The Indian Ocean Tsunami Warning and Mitigation System said there was
“no threat to countries in the Indian Ocean”.
There was a “low likelihood of casualties and damage”, the USGS added.
The Southeast Asian archipelago experiences frequent seismic and volcanic
activity due to its position on the Pacific “Ring of Fire”, where tectonic
plates collide.
In 2018, a 7.5-magnitude quake and subsequent tsunami on Sulawesi island
left more than 4,300 people dead or missing.
A devastating 9.1-magnitude quake struck off the coast of Sumatra in 2004,
triggering a tsunami that killed 220,000 throughout the region, including
around 170,000 in Indonesia.
