Its summit features a 320 m wide and 120 m deep with a densely forested floor containing a lake, and fumarolic activity reported from the area. The 's forested slopes are classified as a potentially active within the epoch, with confirmed eruptions dated to approximately 1290 ± 40 CE, 170 ± 80 BCE, and 400 ± 60 BCE, and an unconfirmed event possibly occurring on March 7, 1911. Proclaimed as the Mount Matutum Protected Landscape under Presidential Proclamation No. 552 on March 20, 1995, by President , the area encompasses approximately 15,600 hectares across municipalities in and provinces, falling under the National Integrated Protected Areas System (NIPAS) as a protected landscape to conserve its natural resources and ecological integrity. This designation recognizes the site's role as a key area within the Volcanic Province, supporting diverse forest ecosystems from dipterocarp lowlands to montane mossy forests at higher elevations. Ecologically, Mount Matutum hosts significant and , including endemic such as various pteridophytes, anurans, and critically endangered like Rafflesia verrucosa, with recent sightings as of 2025 confirming its presence alongside the , contributing to the region's high rates in a mountainous terrain prone to hazards like pyroclastic flows, lahars, and fallout. The protected landscape also serves as habitat for other wildlife, while providing watershed services to surrounding communities, though it faces threats from human activities and potential volcanic unrest monitored by the Philippine Institute of and (PHIVOLCS).

Geography

Location

Mount Matutum is situated in the province of within the region (Region XII) on the island of in the southern . The volcano's summit lies at coordinates 6°21′40″N 125°04′34″E, placing it in a geologically active area of the archipelago. Administratively, Mount Matutum spans the municipalities of , Tampakan, and Tupi in , extending into the municipality of in adjacent Province. This positioning integrates the mountain into the regional landscape of southern , where it serves as a prominent amid rural communities. The volcano is located approximately 15 kilometers north of and 30 kilometers north-northwest of City, the nearest major urban center. It rises northwest of Sarangani Bay, providing a natural backdrop to the coastal zone. At an elevation of 2,262 meters, Mount Matutum stands as the highest peak in Province. From its heights, the mountain overlooks expansive coastal plains bordering Sarangani Bay to the south and the fertile agricultural lowlands to the north and east, which support extensive plantations and other farming in the Polomolok and Tupi areas.

Topography

Mount Matutum is a symmetrical rising prominently from the farmlands of southern in the . Its broad base spans approximately 17 kilometers in diameter, supporting steep slopes that ascend from surrounding lowlands to form a well-preserved . The volcano's elevation reaches 2,262 meters (7,421 feet) above , with a basal area of 241.8 square kilometers and an estimated volume of 42 cubic kilometers, making it a dominant feature in the regional landscape. At the lies a distinct measuring 320 meters wide and 120 meters deep, characterized by a densely forested interior breached to the east by three radial valleys. The floor supports lush , contributing to the 's overall vegetated appearance. The slopes transition through distinct elevational zones, including montane forests at mid-levels and mossy forests near the higher elevations, reflecting the varied ecological gradients along the ascent. Notable surface features include two thermal areas, known as Akmoan and Linan hot springs, situated on the west-southwest flank of the . These hot springs emerge approximately 5.7 kilometers west-southwest of the summit, indicating ongoing geothermal activity associated with the underlying magmatic system. The combination of these elements underscores Matutum's classic stratovolcanic morphology, with its steep, forested flanks contrasting against the adjacent agricultural plains.

Geology

Formation

Mount Matutum is situated within the , a region characterized by intense volcanic and seismic activity driven by . The volcano's formation is primarily attributed to processes along the Cotabato Trench, where the of the Sunda Plate beneath the is being subducted eastward under the Philippine Mobile Belt. This generates in the mantle wedge, producing that ascends to form volcanic edifices like Matutum in the Cotabato Arc. The is composed mainly of andesitic to dacitic lava flows interlayered with pyroclastic deposits, including surges, falls, and flows, which have accumulated to build its composite cone structure. These materials reflect the intermediate to nature of the magma generated in the subduction zone, with calc-alkaline affinities typical of arc volcanism. The eastern and southeastern flanks exhibit extensive pyroclastic deposits, contributing to the volcano's overall volume of approximately 42 km³. As a , Matutum's development spans the current geological epoch, with indicating multiple eruptive phases that have shaped its edifice over the past several millennia. Key growth episodes are evidenced by dated deposits from eruptions around 400 BCE, 170 BCE, and 1290 CE, demonstrating episodic without evidence of pre-Holocene activity for the main cone. These phases involved both effusive and explosive activity, progressively building the symmetrical form observed today. Structurally, Matutum features a central vent marked by a 320-m-wide crater that reaches 120 m in depth and is breached by three radial gorges, allowing drainage and exposing inner walls. The absence of formation underscores its typical stratovolcanic profile, with no major collapse events recorded in its history. This configuration supports a focused magmatic pathway, consistent with its subduction-related origins.

Eruption history

Mount Matutum, a in southern , , has experienced at least three confirmed eruptions during the epoch, characterized by both explosive and effusive activity. The most recent prehistoric eruption occurred around 1290 CE ± 40 years, involving explosive events that produced fallout and possibly pyroclastic flows, based on of volcanic deposits. Earlier events include an dated to 170 BCE ± 80 years, which generated significant fallout, and another around 400 BCE ± 60 years, also explosive in nature with uncertain details on ejecta volume but indicative of magmatic unrest. These eruptions, estimated at VEI 3-4 based on deposit extent, highlight the volcano's capacity for sudden, violent outbursts. Historically, no confirmed eruptions have been recorded since the , though a suspected event took place on March 7, 1911, based on reports of "smoking" from the summit crater, potentially triggered by steam explosions from groundwater heating and possibly phreatomagmatic in nature. This activity remains unconfirmed due to lack of direct observations or deposits, but it aligns with the 's eruption style involving interactions with its hydrothermal system. Overall, Matutum's eruptions have featured pyroclastic flows, dispersal, effusive lava flows, and occasional activity. As an , Mount Matutum is continuously monitored by the Philippine Institute of Volcanology and (PHIVOLCS) through seismic networks, gas emissions tracking, and ground deformation measurements in collaboration with regional observatories. As of November 2025, the volcano remains at Alert Level 0, indicating normal background activity with low levels of unrest, no significant , and minimal gas emissions detected.

Ecology and conservation

Biodiversity

Mount Matutum's biodiversity is characterized by distinct elevation-based ecological zones, ranging from 500 to 2,262 meters above , which support varied forest types including lowland dipterocarp forests at lower elevations, montane forests between approximately 1,000 and 1,700 meters, and mossy forests above 1,500 meters. These zones transition from dense, broad-leaved dipterocarp-dominated woodlands in the lowlands (500–999 m) to cooler, cloud-shrouded mossy forests at higher altitudes (1,500–1,720 m), fostering specialized communities adapted to increasing and reduced temperatures. The mountain hosts high floral diversity, with 154 understory plant species documented across disturbed and undisturbed areas, including herbs, shrubs, vines, and a notable 2% representation of orchids among understory flora. Montane forests exhibit particularly high species richness, as indicated by a Simpson's diversity index of D=0.96 in undisturbed areas, surpassing mossy forest values (D=0.83). Endemic and diverse pteridophytes, such as ferns, contribute significantly, with 105 new distribution records identified across 19 families and 56 genera, including 11 nationally threatened species. While giant ferns and pitcher plants like are reported in the vicinity, the flora underscores the mountain's role in preserving Philippine endemic vascular plants. Faunal assemblages reflect the mountain's isolation and habitat variety, with 81 bird species recorded across nine orders and 35 families, including 35 endemics (30 Philippine-wide and five Mindanao-specific, yielding 43.21% ); notable among these is the critically endangered (Pithecophaga jefferyi), recently sighted on the slopes. Arthropod diversity includes 23 spider species from nine families, peaking at mid-elevations around 1,200 meters. Reptilian fauna features endemic species such as monitor lizards (Varanus spp.), while mammals include the vulnerable (Carlito syrichta), observed in secondary forests. Additional groups, like 13 anuran species with 76.92% , highlight the understory's role in supporting fungi and herbaceous plants integral to these ecosystems. As part of the —a hotspot—Mount Matutum exhibits elevated rates across taxa, positioning it among the nation's most threatened areas due to its unique montane habitats and isolation in . This high , exemplified by over 70% in amphibians and ferns, underscores the mountain's conservation priority for endemic Philippine and fauna.

Protected status

Mount Matutum Protected Landscape was established on March 20, 1995, through Presidential Proclamation No. 552, pursuant to Republic Act No. 7586, also known as the National Integrated Protected Areas System (NIPAS) Act of 1992. This designation encompasses 15,600 hectares spanning the provinces of and in the region, aiming to conserve the area's biological diversity, watershed functions, and geological features. The management of the protected landscape is primarily overseen by the Department of Environment and Natural Resources (DENR) through its Protected Area Management Office (PAMO-MMPL), in collaboration with units and indigenous communities. This framework incorporates multiple-use zoning, including cultural zones that recognize and protect the rights of such as the Blaan, ensuring sustainable resource use while preserving traditional practices. Community involvement is emphasized through initiatives like the "Protect Mt. Matutum" campaign, which promotes awareness and participatory governance to balance conservation with local livelihoods. Key threats to the include habitat loss driven by agricultural expansion, slash-and-burn farming (kaingin), and , which have significantly reduced forest cover since the . To counter these, conservation efforts focus on programs, such as tree-planting drives in biodiversity corridors and partnerships with private entities for sustaining plantations, alongside patrols to curb extraction and timber theft. Additionally, volcanic risk management is integrated into the protection strategy, with the Philippine Institute of Volcanology and Seismology (PHIVOLCS) issuing warnings of potential Pinatubo-scale eruptions for Mount Matutum, prompting hazard mapping and community preparedness measures within a 10-12 km moderate danger zone around the summit. Recent assessments from 2019 to 2022 have underscored the area's high , with studies documenting new records of pteridophytes and anurans that highlight the need for enhanced amid ongoing pressures. In October 2025, two Philippine tarsiers were sighted during DENR monitoring, indicating persistent for , while youth-led filmmaking programs as of November 2025 aim to boost local conservation awareness. Complementing these, DENR-led monitoring initiatives track climate change impacts, such as shifts in and resilience, to inform policies.

Human aspects

Cultural significance

Mount Matutum holds deep spiritual significance for the Blaan people, an indigenous group in southern Mindanao, who consider it a sacred site and the "navel of the earth," created by the deity Almabet as a central element in their cosmology. The mountain is revered as the ancestral origin place of the Blaan, serving as a mythic stronghold and spiritual landmark where ancestral spirits reside, prominently featured in their oral traditions and folklore. Its foothills are predominantly inhabited by Blaan families, who have maintained a profound connection to the landscape for centuries, viewing it as a guardian of their cultural identity. As a key element of , Mount Matutum has been designated a provincial cultural heritage site in , underscoring its role in shaping traditions, rituals, and community identity preservation. Blaan rituals, such as offerings placed in receptacles (sabak) with items like food, coins, or chickens on the mountainsides, seek permission from guardian spirits for activities like or farming, reflecting the mountain's integration into daily spiritual practices. These , part of the broader lagafradongamdono (sacred places) system, emphasize respect for supernatural presences and have helped sustain Blaan ethnobotanical knowledge and weaving traditions tied to the area's resources. Historically, Blaan families have inhabited the slopes and surrounding areas of Mount Matutum, using it as a refuge during periods of external pressures, such as Spanish colonization, and as a source of fertile volcanic soils for . In Blaan , the mountain is depicted as a "gift from ," nourishing the land and symbolizing abundance and resilience for the community. In contemporary contexts, Mount Matutum's cultural importance is recognized through its inclusion in the Mount Matutum Protected Landscape, where designated cultural zones accommodate Blaan traditional activities, including rituals and sustainable resource use, managed in collaboration with the (NCIP). These zones highlight areas of religious, spiritual, and anthropological value, ensuring the continuation of Blaan practices amid conservation efforts. In July 2024, the creation of Juan Loreto Tamayo within the protected landscape raised concerns among environmental groups and indigenous communities regarding potential encroachment on cultural zones and biodiversity. In November 2025, the CineMatutum Video Production Workshop trained youth filmmakers from local schools to document and promote the mountain's cultural and natural stories, supporting conservation and heritage preservation.

Tourism and access

Mount Matutum serves as a popular destination for adventure seekers in , , primarily accessed via organized treks starting from nearby municipalities. The main trailhead is located at Glandang in Kablon, Tupi, approximately 40 kilometers north of City, where hikers begin the ascent after securing necessary permissions. An alternative route, the Keumang , originates from and has been officially designated as the local government's preferred access point for trekkers from that area. Tour operators such as Soxlander Adventures facilitate 2- to 3-day expeditions, providing transportation from or to these jump-off points, often including overnight options for multi-day itineraries. Visitor activities center on the mountain's steep, forested trails to reach the at 2,286 meters above , typically a 4- to 6-hour ascent classified as a major climb with a difficulty rating of 8/9. draws enthusiasts to the slopes, where the area's rich avian supports sightings of endemic along designated trails. The fertile volcanic soils surrounding the mountain also enable agri-tourism experiences, such as guided visits to farms like the Mt. Matutum Agri-Tourism Park or Matutum Blooms Agri Tourism Park, where visitors learn about cultivation amid pineapple, corn, and plantations. Infrastructure remains minimal to preserve the natural environment, with no extensive facilities like lodges or cable cars; basic amenities such as rest areas or water sources are limited to checkpoints managed by communities. Guided tours are mandatory for safety, with porters and DENR-registered guides available for hire at the trailheads to navigate the rugged terrain and ensure compliance with environmental protocols. Accessing the mountain involves challenges including mandatory permits from the Tupi Municipal Tourism Office (₱150 for locals, ₱250 for foreigners) or Polomolok's LGU, which include mandatory orientations on and conservation rules; climbing without these is strictly prohibited to protect the protected landscape. The remote location exacerbates risks from steep inclines, dense vegetation, and latent volcanic hazards like potential pyroclastic flows, necessitating physical preparation and adherence to weather advisories from PHIVOLCS.
