"People who are on the coast or seaside need to be aware of the occurrence of sea tides that are higher than normal," Acting Head of the BMKG’s Center for Engineering Seismology, Potential Geophysics, and Time Signs Muzli said here on Tuesday.
According to him, tidal waves are normal events during a full moon.
A lunar eclipse happens when the earth blocks the sun’s rays from reaching the moon, he explained.
"The phenomenon is caused by the dynamic movements of the position of the sun, earth, and moon. This only happens at the time of the (moon’s) full phase and can be predicted in advance," he said.
A total lunar eclipse occurs when the sun, earth, and moon align, he added. When the moon enters the earth’s umbra, it turns red and is called a Blood Moon.
The total lunar eclipse can be safely witnessed from most parts of Indonesia without the need for special glasses.
"This total lunar eclipse can be witnessed if the weather conditions are cloudy and is safe to be witnessed by the public with the bare eye, without having to use specific glasses," Muzli said.
The lunar eclipse, from its initial phase to the final phase, will last for 5 hours 57 minutes and five seconds, he added.
"While the total eclipse process, from the beginning, the total peak, to the end of the total phase, will last for one hour 25 minutes 44 seconds," he informed.
