Today, on Monday, January 18, 2021, the condition of the Megamas area, Manado, North Sulawesi, looks messy after being hit by the extreme waves.
Lots of rocks, garbage and even dozens of fishing boats crashed onto the land.
Extreme waves overflowed to the main road area in Megamas including entering Manado Town Square (Mantos).
It appears that the road in the area behind Megamas Manado is full of stones from the seafront. There is also trash to the boats that crash into the shop area.
The sea water on Sunday, January 17 afternoon did indeed rise to the mainland. The cause is due to the tidal wave. The Meteorology, Climatology and Geophysics Agency (BMKG) is watching out for waves 2.5 to 4 meters high in Manado, North Sulawesi.
“So the wave height is 2.5 to 4 meters,” said Head of the Center for Maritime Meteorology of BMKG Eko Prasetyo in a written statement reported by Antara, Sunday, January 17.
BMKG said that the high waves were triggered by the push of ocean wave energy which is superposing to the tidal phase of the sea water.
Then, in addition to high waves in Manado, BMKG also issued an early warning of high waves of more than 6 meters in a number of waters in Indonesia which took effect from January 17 at 07.00 am, local time to January 19, 2021 at 07.00 am, local time.
