No idea. Earthquakes usually have aftershocks right?
AI -Singapore can feel earthquakes, but it is very unlikely to have a strong, destructive earthquake on its own.
Here’s why:

Singapore is not on a fault line
Singapore is located in a stable part of the Earth’s crust. It is not on major tectonic plate boundaries like:
Indonesia
Japan
Philippines
These countries sit along the “Ring of Fire,” where earthquakes happen frequently.

Why Singapore sometimes feels shaking
When big earthquakes happen in nearby Indonesia (especially Sumatra), Singapore can feel tremors.
Example:
Large quakes in Sumatra (like those near Sumatra)
Sometimes buildings in Singapore sway slightly, especially high floors.
But this is far-distance shaking, not a local earthquake.

Can Singapore ever get a strong earthquake?
Very rare, but:
Small local tremors are possible.
Very strong local earthquakes are extremely unlikely based on current geology.
Singapore buildings are also designed with some safety margin, especially newer high-rise buildings.
Simple answer:

Feel tremors from Indonesia — Yes

Major destructive earthquake in Singapore — Very unlikely.
Simple Answer for You:
✔ HDB safe
✔ Condo safe
✔ High floor sway is normal

Big destructive earthquake in Singapore — very unlikely
