The group, which included Briton Eleanor Hawkins, then posted pictures to Facebook.
One man posted online: “Does this blue light mean gods are still angry?”
Another villager told a local newspaper: “The sky was bright as if there was a rainbow, but unlike a rainbow, it was all striking blue. We have not seen anything like this before.”
Although the rainbow only lasts a short while they are a striking blue colour, according to many observers.
Scientists agree the light was linked with the earthquake, but believe there is a valid explanation, other than a sign from above.

The sky was bright as if there was a rainbow, but unlike a rainbow, it was all striking blue. We have not seen anything like this before.
On social networks several people, such as Rina Ripau from the nearby village of Ranau, uploading images of the rainbow to their Facebook profiles when they started from last Thursday, a week after the Mount Kinabalu earthquake.
Local geologists describe it as a “blue brushstroke light”.
According to experts, the generation of this light involves the ionization of oxygen in some types of rocks due to high stress before, during and after earthquake and other seismic activities.
