GENERAL DESCRIPTION OF VOLCANO ISLAND 
Taal Volcano is a low cone with an oval crater which has an 
area of about 3 square kilometers. The highest part of the rim 
is on the southwestern side (border) and has an elevation of 
approximately 300 meters. Some parts are considerably lower, 
130 to 150 meters. The crater is roughly in the center of Volcano 
Island, which is triangular and has an area of about 25 square 
kilometers {Plate IV). The island in turn is in the center of 
Lake Bombon, which has an area of approximately 320 square 
kilometers {text fig. 1). For a concise account of the geology 
of this region see Adams. ^ 
On Volcano Island are a number of old craters and cones, the 
most prominent of which is Mount Binintiang Malaqui, situated 
at the northwestern corner of the island. The first authentically 
recorded eruption on the island occurred here in 1707. Since 
that time this cone has been inactive. Saderra Maso ^ has given 
an extensive account of the various eruptions of Taal, which are
