AT LEAST 154 PEOPLE have now been killed after Indonesia was devastated by an earthquake, its resulting tsunami, and a series of volcanic eruptions – all within 24 hours.

The Jakarta Globe newspaper reports that hundreds more people are still missing as a result of the tsunami, which hit the Mentawai islands in Wester Sumatra late on Monday night – hours after local authorities had lifted a tsunami warning following an earlier offshore earthquake, which has been downgraded by the US Geographic Survey to a magnitude of 5.8, from 7.5.

The three-metre-high waves created by the quake resulted in a “wall of white water” pummelling many coastal villages, leaving so many dead that the Washington Post reports there were simply not enough people to dig enough graves, and causing the corpes to be left simply abandoned along the shore.

The situation is not helped by the fact that the bulk of any potential humanitarian aid operation is based in Jakarta, which CNN reports is a full ten hours away (in good conditions).

Meanwhile, rescue operations are continuing at the site of Mount Merapi, the country’s most active volcano, which erupted in the aftermath of the same earthquake and killed 18 people – including a two-month-old baby.

Its eruption has covered the area’s foothills in plumes of dust, while the intense clouds obscuring the cone of the volcano seem set to continue for many weeks.
