[16] Despite having light to moderate shaking, the earthquake caused significant damage to buildings and triggered landslides in East Java.

Latest reports suggest some 170 schools, 12 healthcare buildings, 64 religious locations and 15 other public infrastructures have been compromised.

[17][18] A survey conducted by the BMKG to uncover the cause of damage revealed that many houses were not constructed with earthquake-resistant features.

Shoddy construction methods that did not meet the latest safety codes resulted in structural failures during the earthquake.

[19] The Volcanological Survey of Indonesia added that many of these houses were constructed on young quaternary volcanic and alluvium deposits which amplified the strength of ground motion during the earthquake.

[24] According to the Indonesian National Board for Disaster Management (BNPB), ten homes suffered heavy damage while 85 were moderately affected.

[25] The earthquake disrupted the supply of electricity and operations at a power station, causing blackouts in parts of the Malang Regency.

[9] In the immediate aftermath of the earthquake, the Malang Regency government declared the event an emergency and established a disaster response post.

[33] The BNPB had also reassured some residents that homes with moderate or light damage would be restored, with assistance from local government agencies.

The Ministry of Public Works and Housing would collaborate with the BNPB in efforts to repair homes that were seriously affected by the earthquake.
