Musadat (71) squats with a blank stare facing his son and daughter-in-law who are tearing down and tidying up the ceiling of the terrace of the house in East Suwari Hamlet, Suwari Village, Sangkapura District, Bawean Island, Gresik, East Java, Sunday (24/3/2024). Almost half of the houses collapsed due to a series of tectonic earthquakes in the Java Sea last Friday.

The interior of the house is also destroyed. Musadat temporarily took refuge in his children's slightly damaged house. "In my entire life and the stories from my ancestors, this is the first time there's an earthquake that has caused a house to collapse," said Musadat.

Similar sentiments were expressed by Mat Tosen (71), a resident of Kota Kusuma Village in Sangkapura, who took shelter in a tent in a field across from the Sangkapura Sector Police station. When the earthquake hit and destroyed their house, Mat Tosen happened to be outside with his wife, Zaenab (61).

"Before the third earthquake, there were already two big earthquakes that could be felt. I wasn't brave enough to go inside the house, and then the third big earthquake came and made the house collapse," said Mat Tosen.

Based on data from the Meteorology, Climatology, and Geophysics Agency (BMKG), on Friday, there were three major earthquakes with magnitudes exceeding 5. The three earthquakes originated from a depth of 10-12 kilometers in the Java Sea, between 30 and 40 kilometers west of Bawean Island.

The first major shock occurred at 11:22 with a magnitude of 5.9. After that, there were five aftershocks with magnitudes below 5. The next major earthquake occurred at 12:31 with a magnitude of 5.3. There were then 13 aftershocks. The third major earthquake, with a high destructive power, struck at 15:52 with a magnitude of 6.5.

As of Sunday evening, BMKG recorded that there had been more than 290 aftershocks since Friday afternoon. However, since the third major earthquake, Friday evening, the magnitude of the shaking has decreased although the residents of Bawean Island, with a population of 105,000, still feel it and are traumatized.

Nurlena (45), a resident of Telukjatidawang Village, Tambak District, said that during the third major earthquake, she was frying food in the kitchen. The strong tremor almost made her fall, but she was saved by the wall. The frying pan containing hot oil and uncooked food fell and spilled. Nurlena immediately ran outside the house. "My nephew was in the room, so I grabbed him and brought him outside," said Nurlena.

Some houses, especially their kitchen areas, have collapsed. Nurlena evacuated to a field near her house with her family. Occasionally, she returns to her residence to clean and tidy up materials and to retrieve her family's belongings.

The earthquake was centered in the old fault zone of the Meratus pattern, which indicates that the Java Sea fault line is still active.

Zainal Arifin (45), a resident of Kelompanggubuk Village, Tambak, was also forced to evacuate because his house collapsed. He is still in shock because the house he worked so hard to migrate to collapsed, unable to withstand the repeated attacks of earthquakes from the depths of the Java Sea.

"I have no experience dealing with earthquakes and building houses that are earthquake resistant in the future," said Arifin.

He hopes for guidance from government officials to residents so that during the rehabilitation period, they can rebuild homes that ensure the safety and security of residents even in the event of another earthquake.

Head of the BMKG Earthquake and Tsunami Center, Daryono, said that the earthquake in the Java Sea was shallow and was triggered by an active fault again using a shear mechanism. The earthquake was destructive with a wide spectrum that was felt as far as the west coast of Java Island and the south coast of Kalimantan Island. The shock was centered in a zone of low seismic activity so shallow tectonic earthquakes in the Java Sea are unusual.

"The earthquake was centered in the old fault zone of the Meratus pattern, which indicates that the Java Sea fault line is still active," said Daryono.

This needs to serve as a warning for the people of Bawean Island regarding the nearby active fault. Residents' lives will be marked by jolts with magnitudes that are still impossible to accurately predict.

Emergency

Based on data from the Gresik Regency Regional Disaster Management Agency (BPBD), a series of earthquakes forced 33,745 the lives of Tambak and Sangkapura residents to flee. They consist of 4,975 elderly people, 9,539 children and 19,231 adults. The number of refugees covers 32.1 percent of the population of Bawean Island.

Refugees who have lost their homes due to severe damage need assistance in the form of food, ready-to-consume food and beverages, medicine, blankets, clothing, tents, and/or foldable beds.

An earthquake injured seven people, all with minor injuries. There were three injured victims from Sangkapura and four from Tambak. It is a relief that the earthquake did not result in any fatalities. The injured victims were treated at the Umar Mas'ud Regional Hospital, with some being referred to Gresik on the island of Java.

An earthquake resulted in the damage of 5,333 buildings, 5,078 of which were resident homes in an area of 197 square kilometers. A total of 820 homes were severely damaged, 1,286 were moderately damaged, and 2,972 were lightly damaged. The earthquake also damaged 164 mosques and prayer halls, 76 schools and Islamic boarding schools, and 17 offices, markets, and regional general hospitals.

According to Gresik Regent Fandi Akhmad Yani, the emergency response period for the earthquake disaster on Bawean Island will last for a week, starting from Friday. During this period, residents who are forced to live in shelters will receive aid packages and have their health monitored.

"We are preparing a psychology team to help with trauma recovery for the community," said Fandi.

The government expresses gratitude to all parties who have sent or brought aid for those affected by the earthquake on Bawean Island. Assistance is still needed to ensure the well-being and livelihood of the residents.

During a visit to Bawean Island, the Head of the National Disaster Management Authority (BNPB), Lieutenant General Suharyanto, stated that the government is supporting funding for house renovations. In accordance with President Joko Widodo's instructions, funding for heavily damaged homes is Rp 60 million, moderately damaged homes is Rp 30 million, and lightly damaged homes is Rp 15 million, which will be provided after the emergency response period.

Separately, Amien Widodo, senior researcher at the Disaster Mitigation and Climate Change Research Center of the Sepuluh Nopember Institute of Technology (ITS), reminded that it is very important to increase public knowledge and awareness in disaster mitigation, including earthquake. On Bawean Island, experiences and narratives about the earthquake were weak so that people's safety was more due to good luck or luck.

"How can we make the community aware and resilient to disasters in the future, thus ensuring the safety and security of their lives despite facing disaster threats," said Amien.

The series of earthquakes and the activation of faults near Bawean Island should serve as a warning and lesson for the public to be alert and aware in learning and understanding mitigation.
