ACTNews, SEMARANG – The tidal flood hit the coastal area of ​​Semarang City, Central Java. The flooding that had occurred since Monday (5/23/2022) afternoon had the greatest impact in the vicinity of the Tanjung Emas Port.

"The height of the tidal flood, which coincided with today's high waves, was recorded at 210 centimeters," said Retno Widyaningsih, Head of the Tanjung Emas Maritime Meteorology Station in Semarang, according to Antaranews.

Tidal flooding and high waves began around 01.00 p.m. Western Indonesia Time, making the runoff to the mainland feel quite heavy. The collapse of a seawater embankment in the Tanjung Emas Port Area exacerbated the incident.

As a result, tidal flooding with heights ranging from 0.4 to more than 2 meters affected over 1,255 families. Three sub-districts were severely affected: Tanjung Emas Village, Bandarharjo Village, and Kemijen Village.

The Masyarakat Relawan Indonesia (MRI) Team and Aksi Cepat Tanggap (ACT) Semarang City worked tirelessly at the disaster site to evacuate residents and valuables belonging to residents until Monday midnight. Medical volunteers will conduct free health services following the action.

"Residents require ready-to-eat food, hygiene kits, blankets, food supplies, baby clothes, medicines, and emergency tents to survive. We invite Generous Friends to assist our brothers and sisters in Semarang and its surrounding areas that have been affected by the flood. Let us ease their burden with our generosity," Wahyu from the ACT Central Java Program team stated.

According to Ganis Erutjahjo, the Coordinator of Observation and Information at the Tanjung Emas Maritime Meteorological Station in Semarang, the Perigee phenomenon, the closest distance between the earth and the moon, caused the tidal wave.

This perigee can occur because the moon's orbit around the Earth is not a perfect circle but rather slightly elliptical. This phenomenon has the potential to result in a greater increase in maximum tidal height.

According to Emanuel Sungging, Head of the Dissemination Division of the National Institute of Aeronautics and Space (LAPAN), the closest distance to the moon during this Perigee phenomenon will be around 364,390 kilometers from the center of the earth.

Several parties have warned of the possibility of tidal flooding that could last until May 25, including the local government, which is also on standby until now. "We are now requesting that the entire Pantura staff coordinate on standby, particularly in Semarang City, Demak, Pati, and Pekalongan," said Central Java Governor Ganjar Pranowo. []
