Mount Hibok-Hibok is a stratovolcano

Physical Features

Volcanologists classify Hibok-Hibok as a stratovolcano and dome complex with an elevation of 1332 metres (4,370.1 ft) and a base diameter of 10 kilometres (6.2 mi).

It has six hot springs

 (Ardent Spring, Tangob, Bugong, Tagdo, Naasag and Kiyab), three craters (Kanangkaan Crater, site of the 1948 eruption; Itum Crater, site of 1949 eruption, and Ilihan Crater, site of 1950 eruption).

Its adjacent volcanic edifices are Mt. Vulcan, 580 metres (1,902.9 ft) high, NW of Hibok-Hibok; Mt. Mambajao, 1552 metres (5,091.9 ft) center of Camiguin; Mt. Guinsiliban 581 metres (1,906.2 ft) high, southernmost Camiguin; Mt. Butay 679 metres (2,227.7 ft); and Mt. Uhay, N of Mount Ginsiliban. There are also domes and cones at Campana Hill, Minokol Hill, Tres Marias Hill, Mt. Carling, Mt. Tibane, and Piyakong Hill.

The first recorded eruption occurred in 1827 and a similar activity followed in 1862..

s and subterranean rumblings began to be felt on the island, which increased in severity until April 30 when a volcanic fissure opened up 400 yards southwest of the village of Catarman, on the northwest flank of Hibok-hibok Volcano. From the opening, lava was continuously ejected and poured into the sea for four years destroying the town. At the same time, the vent started gaining in height and width thus forming Mt. Vulcan.

visited the area, and described the mountain as a dome, about 1950 feet (594.4 m) in height, without any crater, but still smoking and incandescent at the top.

Portion of the old town where the cemetery was, has sank into the sea and is now marked with a huge white cross off the coast. The settlement was relocated to where the present Catarman town center is now located. The remains of old Catarman like the ruins of the ancient Spanish church, convent and a bell tower is now called Gui-ob.

1897

In 1897, Hibok-Hibok emitted white sulfurous vapors which damaged farms on the island. Solfataric activity continued up to 1902.

1948 to 1951

From 1948 to 1951, Mt. Hibok-Hibok constantly rumbled and smoked. There were also landslides and earthquakes followed by dome building and nuee ardente. The Peléan eruption

In the morning of December 4, 1951, the volcano erupted again. This, time, however, it unleashed boiling lava, poisonous gases, and landslides enough to destroy nearly 19 squares kilometers of land particularly in Mambajao

. All in all, over 3,000 people were killed. Before the eruption of Mt. Hibok-Hibok in 1951, the population of Camiguin had reach 69,000. After the eruption, the population was reduced to about 34,000 due to massive emigration.

Volcanologists observed an eruption pattern observed during the 1948-1952 eruptions (a cycle of four phases) beginning with a short period of emission of steam from the crater and avalanches of volcanic materials, followed by explosions or steam blast with emission of heavy clouds of steam, ash and other fragmentary volcanic materials with a strong possibility of the development of pyroclastic flows. The third phase involves eruption of incandescent materials, emission of ash and steam in large amounts, formation of flows and occasional minor crater outbursts, and finally a decrease in steam and other ejecta from the crater.
