2026 Mindanao Earthquake

2026 Mindanao Earthquake, a 7.8 magnitude tectonic earthquake, occurred at 07:37 local time on 8 June 2026 off the coast of Mindanao Island in southern Philippines. According to the United States Geological Survey (USGS), the quake was recorded 26 kilometers southwest of Kablalan municipality in the Soccsksargen region of Sarangani Province, in the Celebes Sea. The earthquake caused severe building damage, landslides, loss of life, and widespread displacement, and triggered tsunami warnings in Japan, Indonesia, and the Philippines.

Philippine Institute of Volcanology and Seismology (PHIVOLCS) Director Teresito Bacolcol stated that the earthquake originated from movement along the Cotabato Trench and is the strongest earthquake in the Philippines in the past 50 years.

The earthquake’s magnitude was measured at 7.8 (mww) by the USGS. According to Philippine Institute of Volcanology and Seismology (PHIVOLCS), the quake occurred at a depth of 33 kilometers, while the USGS recorded it at 55.2 kilometers. The epicenter was located 32 kilometers southwest of the town of Maasin in Sarangani Province. The earthquake was initially reported as magnitude 8.2 but was later revised to 7.8.

PHIVOLCS recorded a total of 1,055 aftershocks between 1.3 and 6.7 magnitude as of 07:00 on 9 June 2026. Approximately two hours after the main shock, a strong 6.1 magnitude aftershock occurred; another 5.1 magnitude aftershock was recorded on 9 June. Authorities warned that buildings with cracks could collapse due to aftershocks.

PHIVOLCS Director Teresito Bacolcol noted that this earthquake was the strongest to follow the 8.1 magnitude quake triggered by the same trench on 17 August 1976. The 1976 earthquake killed approximately 8,000 people and generated tsunami waves between 8 and 10 meters high that inundated entire towns and provinces. A similar magnitude earthquake in 1990 in northern provinces caused over 1,000 deaths and extensive damage.

Office of Civil Defense (OCD) Assistant Spokesperson Diego Agustin Mariano announced on 9 June 2026 at 06:00 that the death toll had risen to 37. Of these, 33 were recorded in the Soccsksargen region and 4 in the Davao region. Regionally, 18 people died in Sarangani Province, 12 in General Santos City, 3 in South Cotabato, and 4 in the Davao region. Mariano stated that the numbers were still under verification.

OCD Spokesperson Junie Castillo said the majority of fatalities resulted from debris and rubble falling from collapsed buildings and structures. A significant portion of the deaths in Sarangani Province occurred due to landslides that buried homes on mountain slopes in the town of Glan. The number of injured was confirmed at 479, with 456 in Region 12 and 23 in the Davao region. Four people remain listed as missing.

The earthquake affected approximately 88,000 people across southern Mindanao, of whom 22,690 were displaced. The majority of displaced persons sought shelter in emergency evacuation centers. Many residents reportedly abandoned their homes due to fears of a tsunami. OCD plans to establish a tent city to accommodate those unable to return to their homes.

According to OCD, 17,689 households or 77,186 individuals were directly affected, with 5,343 households currently residing in evacuation centers. Authorities noted that many residents continued to remain in open areas due to safety concerns regarding structural damage to buildings and the risk of aftershocks.

Initial government damage assessments indicated that approximately 2,000 homes and 117 public buildings and facilities across several provinces sustained damage. A total of 1,889 homes were damaged, approximately 1,500 of which were completely destroyed. Property losses were estimated at 15 million pesos (approximately $243,607 USD), with assessments ongoing.

Infrastructure damage included 9 bridges and 19 roads. Total infrastructure losses were projected to exceed 900 million pesos (approximately $14.6 million USD). General Santos International Airport was closed, and 63 domestic flights were canceled except for humanitarian aid flights. Search and rescue operations were concentrated in General Santos City and Sarangani.

PHIVOLCS issued tsunami warnings for nine coastal provinces, urging residents to immediately move to higher ground or inland areas. The Pacific Tsunami Warning Center (US) predicted that some coastal areas could experience waves exceeding 3 meters above normal tide levels. The highest recorded wave in the Philippines was 1.4 meters, and the only reported tsunami damage was limited to six informal structures on a wooden pier in a coastal village. Smaller waves reached coastlines in Indonesia, Palau, and southern Japan. PHIVOLCS lifted the tsunami warning after observing that wave heights remained below levels capable of causing damage.

The earthquake occurred on 8 June 2026, the first day of the school year. The Department of Education (DepEd) announced that as of 9 June, more than 4 million students and 156,000 teachers and school personnel were affected. DepEd Assistant Secretary for Operations Malcolm Garma stated: "Our number of affected students has exceeded four million. By affected, we mean not only those in schools but also those whose homes were damaged. Additionally, approximately 156,000 teachers and non-teaching personnel were affected."

Rapid assessments indicated that over 1,000 classrooms in 231 public schools across five regions sustained light to severe damage. It was determined that 6,000 public school buildings must undergo safety evaluations before classrooms can reopen. Garma stated that buildings with compromised structural integrity would be demolished. Schools without electricity, water, or internet access were instructed to adopt alternative teaching methods.

Images showing the collapse of a school building at Matanao National High School circulated on social media. Garma clarified that the building had been decommissioned prior to the earthquake and contained no students. A report of a student killed in a landslide in Sarangani was under verification.

President Ferdinand Marcos Jr. activated all disaster response agencies, including the Office of Civil Defense and the National Disaster Risk Reduction and Management Council (NDRRMC). Marcos dispatched senior defense and response officials from Manila to oversee search and rescue operations, the distribution of tens of thousands of food packs and construction materials, and damage assessments of bridges, roads, and other infrastructure.

OCD announced it would provide generators and fuel to ensure uninterrupted hospital services. The United States, a defense ally of the Philippines, confirmed coordination with Manila and readiness to support relief efforts. France, Japan, and New Zealand also issued messages of support.

The Senate’s new majority bloc announced on 9 June that it would donate one month’s salaries to aid and rescue efforts in the affected regions. Led by Senate President Pro Tempore Sherwin Gatchalian, the group issued a joint statement: "As a personal contribution, the Senate New Majority stands ready to donate one month’s salary to support affected communities." The group extended an invitation to members of the minority bloc to join the initiative.
