Direct answer
Eruption History, in this definition, is limited to the following inspected scope. The profile describes Mayon’s morphology, tectonic setting, documented eruption periods, and the database’s dated historical chronology. PHIVOLCS is the Philippine operational source for current Mayon bulletins, observations, alert levels, and public hazard information. The answer carries the source boundaries forward and does not infer authority from a neighboring topic.
Definition
Use the term only for the source-backed scope stated here; keep adjacent concepts separate unless a typed relationship is explicit.
A useful definition states both inclusion and exclusion conditions so a machine answer cannot silently widen it.
Applied scope: The profile describes Mayon’s morphology, tectonic setting, documented eruption periods, and the database’s dated historical chronology. PHIVOLCS is the Philippine operational source for current Mayon bulletins, observations, alert levels, and public hazard information.
Definition and operating context
The canonical concept owner is mayon-rajan. This route may apply risk; it cannot redefine or inherit the authority of its canonical owner.
This property may publish bounded hazard education, official-source routing, place interpretation. It must not publish real-time alert substitution or religious-name conflation.
Evidence and exact locators
Mayon volcano profile and eruptive history — Geological Summary; Eruptive History; eruption rows and cited references. Establishes: The profile describes Mayon’s morphology, tectonic setting, documented eruption periods, and the database’s dated historical chronology.
PHIVOLCS-LAVA: Local Active Volcanoes Archive — Volcano Status; Bulletins; monitoring and hazard-information navigation. Establishes: PHIVOLCS is the Philippine operational source for current Mayon bulletins, observations, alert levels, and public hazard information.
What the evidence does not establish
The database is a living secondary compilation and does not provide the current PHIVOLCS alert, a forecast, hazard-zone permission, or operational advice; historical entries may be revised.
The portal is time-sensitive; this packet records no alert, reading, forecast, or safety instruction and cannot replace the latest official bulletin.
This route must not claim real-time alert substitution.
This route must not claim religious-name conflation.
