The majority of the 138 fatalities from the earthquake took place on Sangihe Island, where a mudflow occurred. Earthquake The w 7.9 mainshock was preceded by foreshocks. The mainshock had a maximum Modified Mercalli intensity (MMI) of IX (Violent) in Davao and Sarangani. MMI VIII (Severe) was observed in Talacogon; MMI VII (Very strong) was observed in Cotabato, Baganga, Butuan, Cabadbaran and Tandag.Series on Seismology 1985 4 755 Southeast Asia Association of Seismology and Earthquake Engineering 974-8202-18-6 Damage and casualties Indonesia On Sangihe Island, where the earthquake produced about four minutes of strong shaking, people were thrown to the ground, and there were 20 deaths. Homes located on the swamp were raised from the ground and tilted on their sides or collapsed. Many buildings including schools, homes and businesses in Enemawira, Peta, Tabukan and Tamako, collapsed. Severe damage was also reported at Manganitu and Kendahe. Rockfalls were widespread along the rocky coastline while fractures appeared in the ground, some ejected water. Subsidence occurred in the Menalu area; the sea inundated parts of the plain, forcing residents to relocate. Coastal subsidence also occurred at Peta Bay, Tamako and Tabukan.National Geophysical Data Center / World Data Service (NGDC/WDS) https://www.ngdc.noaa.gov/hazel/view/hazards/earthquake/event-more-info/2973 Global Significant Earthquake Database 1972 NOAA National Centers for Environmental Information 19 March 2023 10.7289/V5TD9V7K National Geophysical Data Center At Menalu Bay, 1,000 m3 of material fell into the water from 80 m height. West of that, a mudflow traveled 1 km down from Endongo Hill, burying 117 villagers and 29 houses. The mudflow buried the area under 6 m of material; it subsequently dammed a river, causing it to overflow. In Manganitu, bridges were washed away.Soloviev S. L. Go CH. N.

Ground fractures, avalanches and rockfalls occurred but there was no coastal subsidence. During the earthquake, people were unable to stand. Many brick buildings were ruined and some huts sank to one side. Similar environmental effects and damage occurred on the Talaud Islands but there were no casualties. Philippines Shaking lasted half a minute on the Sarangani Islands, where many trees toppled. At Davao, strong oscillations were recorded for two to five minutes; people in the city were thrown to the ground. Huts made from palm leaves sank on their side and some stone walls collapsed, and cracks in the ground ejected sand and water. Along the Agusan River, the water moved in an east–west direction, tossing boats. The earthquake was also felt in Baganga, Talakogon, Kotabato, Butuan, Bohol, Cebu and Leyte. Volcanic eruption The Straits Times and Malay Mail reported a volcanic eruption at Mount Awu. It occurred at the same time as the mudflow at Endongo Hill. A "tidal wave" 15 m high devastated the coastline. The eruption measured 2 on the volcanic explosivity index.National Geophysical Data Center / World Data Service (NGDC/WDS): NCEI/WDS Global Significant Volcanic Eruptions Database.
