The effects of the Kanlaon Volcano eruption on July 9, 2026 continue to persist in Cebu the day after.

This is according to the Environmental Management Bureau (EMB) of the Department of Environment and Natural Resources (DENR)-7 in an update on July 10, Friday.

“Mt. Kanlaon eruption still continue to persist, as evidenced by reported ashfall incidents across areas along the trajectory of the wind path,” said EMB said in a Facebook post.

EMB said data from its monitoring instruments show that air quality concentrations for PM2.5 and PM10 as of 6 a.m. on July 10 are within safe guidelines values.

PM2.5 refers to fine particles in the air with a diameter of 2.5 micrometers or smaller.

PM10 includes particles with a diameter of 10 micrometers or smaller.

EMB has confirmed that the ash that reached Cebu on July 9 is the volcanic ash spewed by Kanlaon Volcano when it erupted morning that day.

The ash reached Cebu, particularly the central part of the island, because the wind wind trajectory from Negros Island, particularly from the area where the volcano stands, was going generally east.

“Atmospheric simulations (using the NOAA HYSPLIT model) indicate that the trajectory of air parcels and volcanic emissions from Mt. Kanlaon is BLOWING EASTWARD, directly affecting several portions of Central Cebu,” EMB said.

EMB continues to advise the public the following steps to protect oneself from ashfall: 

  • Wear masks (N95 is highly recommended) if you need to go outside.
  • Close windows and doors to keep the ash from entering your homes.
  • Protect your eyes and stay hydrated.
  • Monitor vulnerable family members, especially those with asthma or respiratory conditions.

ERUPTION

The Kanlaon Volcano erupted for three minutes early morning on July 9 AND spewed ash that blanketed areas near the volcano, most prominently in Canlaon City.

The Philippine Institute of Volcanology and Seismology (PHIVOLCS) said the eruption generated a dark gray eruption plume that rose two to three kilometers above the crater.

PHIVOLCS said what occurred was a moderately explosive eruption.
