04/1969 (CSLP 29-69) False activity reports during Didicas eruption

Card 0489 (07 April 1969) Large ash clouds reported

Volcanic activity is now reported from Babuyan Island, 70 km NW of Didicas Volcano (figure 1). Large ash clouds are being emitted at 10-minute intervals. Note: There are two active volcanoes on Babuyan Island -- Babuyan Claro and Smith. It is not yet known which of these is presently erupting.

Card 0490 (08 April 1969) Aerial reconnaissance shows no signs of activity at Babuyan volcanoes

"COMVOL air reconnaissance Babuyan Island indicated neither signs of present or recent activity. Island has two volcanoes, Smith or Mt. Babuyan clearly observed with no signs of activity. Older and taller volcano, Mt. Pangasun or Babuyan Claro covered by cloud bank but no ash deposits on lower slopes or steam emission apparent."

Card 0515 (24 April 1969) Eruption reports were unfounded

The alleged eruption of a volcano in Babuyan Island proved to be unfounded. Air reconnaissance over the Island failed to show any signs of any on-going activity or one of very recent occurrence. There are two volcanoes in the island. Smith or Mount Babuyan, the younger and lower of the two was clearly visible and no break was observed on any part of its grassy crater and slopes. No ash deposits on the trees of the lower half of the volcano were detected, and as no eruption emission was seen rising above the cloud bank, it can be surmised that this volcano too has not manifested any very recent activity.

02/1980 (SEAN 05:02) Hot mudflows force evacuation

Hot mudflows from Babuyan Claro [but see below] damaged rice fields and roads, and forced the evacuation of nearby residents according to a Kyodo radio report dated 8 February. PNA radio reported that a three-man COMVOL was sent to study the volcano. . . .

03/1980 (SEAN 05:03) Last month's "hot mudflows" not volcanic

A COMVOL investigation has determined that press reports of hot mudflows at Babuyan Claro were incorrect. COMVOL found that a landslide, probably triggered by continuous rainfall, had occurred at 600 m above sea level on the NW flank.

Information Contact: O. Peña, COMVOL, Quezon City.

Five Pleistocene-to-Holocene volcanic centers occupy Babuyan de Claro Island north of Luzon. The largest edifice is Mt. Pangasun (Babuyan Claro), an active stratovolcano with two summit craters 300 and 400 m in diameter. The symmetrical basaltic andesite cinder cone of Smith Volcano (Mount Babuyan), located 4 km to the NW of Babuyan Claro, rises to 688 m and is the youngest volcano on the island. Both Babuyan Claro and Smith volcanoes have apparently been active in historical time, although the identity of the erupting volcano is not always certain. Askedna Hot Spring is located at the southern base of Babuyan Claro.

The symmetrical, unvegetated basaltic andesite cinder cone of Smith Volcano (Mount Babuyan) is the youngest of five Pleistocene-to-Holocene volcanic centers on the island of Babuyan Claro. The largest edifice is Mt. Pangasun (Babuyan Claro), an active stratovolcano with two summit craters 300 and 400 m in diameter. Both Babuyan Claro and Smith volcanoes have apparently been active in historical time, although the identity of the erupting volcano is not always certain.

Conical Smith volcano in the foreground is one of five Pleistocene-to-Holocene volcanic centers occupying Babuyan de Claro Island north of Luzon. The symmetrical basaltic andesite cinder cone of Smith Volcano (also known as Mount Babuyan), rises to 688 m and is the youngest volcano on the island. Both the higher Babuyan Claro volcano and Smith volcano have apparently been active in historical time, although the identity of the erupting volcano is not always certain.
