Magma commonly moves up towards the surface by creating cracks in the crust. It flows inside of the cracks, which grow upwards as the magma applies pressure and damages surrounding rocks. These magma-filled cracks are known as dikes and they are an important form which allows magma to travel easily through the crust.

Dear EOS Community,
What a busy and exciting year for the Earth Observatory of Singapore (EOS). In early 2018, we kicked off the celebration of our 10thyear as a Research of Excellence at the Nanyang Techonological University (NTU). Marking a decade of geohazard research in Asia, EOS has built a team of outstanding scientists and staff to move the institution forward for years to come.

Even though sea-level rise (SLR) has been studied by scientists for more than 35 years in over 70 individual studies, global and local SLR projections remain uncertain.

On Sunday (29 July 2018), I learnt about the strong 6.4-magnitude (M) earthquake in Lombok, Indonesia. As we have friends living there, I wanted to visit to see what aid we could organise for the people there. So my husband and I went to Lombok with some friends, and we linked up with other humanitarian aid groups to visit the Sembalun area, which is about 1,000 metres above sea level, at the foothills of Mount Rinjani, one of the most scenic volcanoes in the world.

Let’s face it – the use of plastics has been our way of life. How many of us (at least those in our twenties) can recall going to the wet market with our parents when we were young without using a single plastic bag? Probably none. That’s the way we were brought up.
But just because something has become habitual and is a social norm does not mean that it is right, or that it has to stay that way.

On 28 September 2018, central Sulawesi in Indonesia got struck by a powerful earthquake measuring 7.5 in magnitude (M). A tsunami that followed later devastated the city of Palu and the town of Donggala, leaving more than a thousand dead and even more homeless.
