Magnitude 4.8 earthquake — Pulau Pulau Tanimbar, Indonesia

A magnitude 4.8 earthquake has struck the Tanimbar Islands in eastern Indonesia, according to the United States Geological Survey.

The tremor hit at around half past twelve GMT on 11 August, centred roughly 30 kilometres beneath the surface. That's a moderate depth — shallow enough to be felt quite noticeably by anyone nearby, but deep enough to spread the shaking over a wider area rather than concentrating it in one spot.

What a 4.8 actually feels like

For those of us who've never experienced one, a magnitude 4.8 quake is the sort that makes the windows rattle, sets hanging lamps swinging, and might knock a few things off shelves if they're not secured. Indoors, you'd definitely notice it and probably feel a bit unsettled. Outdoors, it's less obvious unless you're standing still. It's not usually strong enough to damage well-built structures, though older or poorly constructed buildings might suffer cracks.

The Tanimbar Islands — also called Pulau Pulau Tanimbar locally — are a remote and sparsely populated chain in the Maluku province, sitting between Timor and the Aru Islands. They're part of the Pacific Ring of Fire, that vast horseshoe of seismic and volcanic activity that encircles the Pacific Ocean, so earthquakes are a fairly regular part of life out there.

What we know so far

At this stage, there are no reports of casualties or significant damage, though information from such a remote area can take time to filter through. The quake is still being monitored, and the data remains provisional as seismologists continue to analyse the readings.

Indonesia sits atop several tectonic plates that are constantly jostling for position, which is why the country experiences thousands of earthquakes every year. Most are too small to notice, but moderate ones like this serve as a reminder that the ground beneath our feet is never quite as solid as it seems.
