Lombok dan Bali terpapar risiko gempa dan tsunami karena pertemuan lempeng Bumi dan aktivitas lempeng yang menyesar ke utara.
Shallow but powerful earthquakes on Lombok have resulted in around 100 deaths and destroyed buildings.
Caught in the middle: Lombok and Bali are exposed to earthquake and tsunamis risk due to a tectonic plate boundary to the south, but also a unique zone of activity that thrusts to the north.

The final design of the National Energy Guarantee promises that the policy will drive down power prices. But there is precious little evidence for this assertion.
Rampasasa people are from Waemulu village, Flores – near Liang Bua where ‘the Hobbit’ fossils were discovered.

Modern day people of short stature became physically small due to the effects of living on a small island or forested environment. But we're not sure why "the Hobbit" of Flores was so small.

Prosecuting whistleblowers has the potential to further shake public confidence in Australia's criminal justice system.
Cutting immigration to Australia will impact the country’s demographic composition, with consequences for the working age population and income tax base.
Politicians across the spectrum have at some point targeted immigration as a contributor to out-of-control population growth. But would reducing, or banning, immigration take pressure off cities?
We need to know gene editing technology is precise before we try to use it to cure diseases.
A new study found the Cas9 gene editing scissors don't stop cutting after we tell them to.
Southern bull kelp can drift huge distances before washing ashore.
A chance discovery of some kelp that floated for 20,000km before washing up on an Antarctic beach has opened up a new chapter in our understanding of the currents that swirl around the Southern Ocean.
One Nation leader Pauline Hanson says Australia has ‘run away rates of immigration’.
One Nation leader Pauline Hanson said Australia is "the highest-growing country in the world", with population growth "double than a lot of other countries". Is that right?
