RECONNAISSANCE OF SOUTHEASTERN LUZON. 465 



1616. — Simply a notice of an eruption. 176C. — Eruption, July 20, lasting 6 

 days. A current of lava is said to have descended the eastern slope. 1800. — 

 Stones, sand, and ashes were thrown out. Some adjacent settlements, Cagasaua, 

 Budiao, and others, were destroyed and some cultivated fields ruined. The last 

 and most violent activity occurred during the closing days of October. 1814. — 

 On February 1 there was a violent eruption. A torrent of "fire, lava, and large 

 hot stones" descended the southern slope of the cone. According to some descrip- 

 tions, 1,200 dead were collected after the eruption which burned and ruined the 

 towns of Gamalig, Cagsaua, and Budio and half of Albay and Guinobatan. 1827. — 

 In June a period of eruption began which lasted until February, 1828 (?). 

 1835. — ^An eruption in the month of May. 1845. — An eruption on January 21. 

 1846. — An eruption of ashes. 1851. — Two small eruptions of ashes. 1853. — An 

 eruption on the 13th of July lasting only a few hours. Ashes fell and a great 

 number of hot stones rolled down the slopes of the volcano, destroying many 

 houses and causing the death of 33 persons. 1855. — ^An eruption. 1855. — On 

 December 17, ashes fell on the adjacent towns and some lava was poured out. 

 1871. — A not very violent eruption on December 8. Ashes, sand, and lava were 

 thrown out of the crater. The wind carried the ashes toward Camalig and 

 Guinobatan, forming a layer 4 millimeter's thick as these places. Streams of 

 "lava" descended toward Albay and Legaspi. Two persons were suffocated in 

 Bocton and one was burned in Buyuan. 1872. — In September, an eruption 

 occurred which lasted four days. 1873. — An eruption took place lasting from the 

 middle of June until July 22. 



1881-1882. — An eruption noted for its length began on July 6, 1881, and 

 lasted until the middle of the next year. It was described by Abella as character- 

 ized by the tranquil eruption of lavas from various places near the summit of 

 the cone. The lava issued in a nearly solid state, or it was fragmental and 

 incoherent, but always incandescent. On November 21 and December 14 the 

 eruption was more violent and great quantities of steam and ashes came from 

 the crater. Ashes fell on Camalig and Guinobatan. 



1885. — From November 21 to December 2 there was a slight eruption, the 

 materials ejected descending as far as 400 to 600 meters from the summit. 

 1886-1887. — This period of intermittent eruption began July 8, 1886, when 

 volcanic material descended the south slope of the cone. On February 22 ashes 

 fell in the vicinity of Camalig, and on March 9, ashes fell in Guinobatan. 1888. — 

 Eruption of ashes on the summit of the cone on December 15. 1890.— In Sep- 

 tember an eruption of little importance. 1891. — Slight eruption in October. 

 1892.— In the eruption of February of 1892 volcanic materials descended the 

 slopes of the cone. Many inhabitants of Libog and Camalig left those towns in 

 fear, because of the length and violence of the eruption. It is reported that the 

 cone lost 100 meters in height during this period. 1893. — An eruption occurred 

 during October. Volcanic materials descended the slope of the cone to an 

 elevation of about 710 meters, or about the limit of vegetation. 1895. — A slight 

 eruption in July. Some incandescent materials thrown out in November. 1896. — 

 An eruption of little importance began in August, similar to the one of 1895. 

 Incandescent materials were thro-\vn out in September. 



1897. — This, the most destructive eruption of Mayon since the year 1841, began 

 May 23. On Jime 25 and 26 it reached its culmination in a disturbance which 

 lasted 17 hours. The activity then decreased gradually and terminated in July.
