Very difficult to enumerate/type here using a fone. But we have techniques to monitor a volcano's activity. Ground deformation (gps, edm, satelite interferometry, gravity, precise leveling), geochemistry, seismic, electeomagnetics, visuals, etc.

Yung reported fissures this morning are these arcuate or convex shape towards Taal or linear? Has anyone measured if there are traces of magmatic gasses coming from this fissures?
