First-Hand Narrative of the Violent 1911 Taal Volcano Eruption which Killed More than a Thousand People

“Tiny” Taal Volcano, at just 311 meters or 1,020 feet above sea level considered the world’s smallest active volcano, is also among the deadliest1. It has had a total of 33 historical or documented eruptions2. One of these, the 1754 eruption, lasted for almost seven months and redefined the terrain in the Taal-Lemery area, closed off Taal Lake’s access to Balayan Bay and changed its waters from marine to

Next to this terrain-redefining eruption, the most notable and especially so because it occurred in the modern era, was the violent 1911 phreatic eruption3 that hurled rock fragments called tephra into the atmosphere, caused 25 to 80 centimeters of ash-fall and acid rain, formed seiches4, generated shock waves and caused the fissuring or breaking of terrain.

The base surge5 from the explosion obliterated the barrios on the volcano island and ash-fall affected the towns of Talisay, Laurel, Tagaytay and Agoncillo. In all, 1,335 people were killed by the eruption1. A total of 2,000 square kilometers was affected. Ash and other volcanic debris fell as far away as Manila6.

Wary of the consequences, Phivolcs has in place a contingency plan to evacuate the entire volcano island as well as the lakeside villages of Talisay, Tanauan City, Agoncillo, Balete, San Nicolas and Laurel should the volcano exhibit symptoms of the same magnitude and nature as the 1911 eruption6.

According to the author Jay Robert Nash, writing in his book “The Darkest Hours,” the 1911 Taal Volcano eruption occurred on the 30th of January. It was preceded by earthquakes that shook the countryside surrounding the volcano as far as 100 miles (160 kilometers) away8. This meant that the tremors would have been felt as far north as Baliuag in Bulacan and as far south as the island of Mindoro. These went on unceasingly for a day then, just before the explosion, the volcano started to emit columns of black smoke.

According to Nash, a group of American engineers were encamped at the municipality of Laurel, at the time still called Bayuyungan, on 28 January just a quarter of a mile away from Taal Lake. An engineer whose name was Couch described what happened early in the morning:

“About 3:00 a.m., severe detonations and an electrical display occurred. Crater smoke was carried off southward, and this condition lasted about three minutes. Earthquakes were felt at daylight, January 28, and ashes fell at camp all day. This continued, and at 4:00 p.m. January 29, a violent quake occurred, another at 11:00 p.m., and one about 1:00 a.m. On January 30, I was awakened by a loud rumbling noise. The explosions resembled heavy artillery.8
These explosions turned out to be no more than the precursor to the main event. The most violent explosion occurred about 2:20 in the morning, and Couch continued on with his narrative:
“…before I could get out of bed, an explosion of indescribable severity took place. Smoke came out of the crater in dense clouds. The rumbling noise grew louder and louder, and then became a heavy report (in this context, like the sound of a big gun firing). I then saw the mud issuing from the crater as a cloud. In a few seconds, I saw this cloud drifting across the lake toward our camp. Our camp was then swept by a heavy wind which broke the tent ropes and threw the tent into the air. This atmospheric disturbance threw me a distance of about fifteen feet. A rain of ashes fell about eight inches deep, the air was oppressive, and we gasped for breath for twenty seconds.8
Filipinos who lived on the volcano island and other villages close to the volcano were not as fortunate as the American engineers. According to Nash, thirteen villages and towns were completely destroyed by “the blast of hot mud mixed with sulfuric acid, flaming stones and rocks and searing ash.”

Nash also described how one villager who was awakened by the explosion watched how his son, who had run to the door, was instantly killed by a thin layer of boiling mud. Meanwhile, in another village, a man awakened to find the same boiling mud beginning to fall from his roof. He barely managed to escape, running from his house to dive into the lake and swim to safety.

The violence of the explosion was perfectly captured by Nash in his graphic description:

“Mud, ashes and gases moved in a whirlwind sheet outward from Taal as it vomited. Everything in the path of this volcanic hurricane was flattened. Trees were cut down to stubby, splintered stumps. Plants were carbonized for a distance of six miles. Every blade of grass within ten miles was destroyed. Nothing lived three miles east and nine miles to the west of the crater.8

Taal Volcano went quiet for 54 years after this cataclysmic 1911 eruption, and the next time it went up again, in 1965, it was not as violent and casualties were limited to just 200 persons. There were seven more mild eruptions since, the last being in 1977. This means that Taal Volcano has been relatively quiet for all of 40 years; and it has been 52 years since the last violent eruption of 1965.

Not that this really means anything because there does not appear any numerical patterns to the intervals between its violent eruptions. For instance, the violent 1754 eruption was preceded by another violent one in 1749 just five years earlier. However, after the 1754 eruption, the next violent one was in 1911 which was 157 years later.

What we do know is that Taal Volcano is more than just a postcard picture. It is a deadly killer which will likely rise up again. Just when is what we do not know; but we can all keep praying it will not happen soon, especially if it will be anything like the 1911 eruption.
