Ibu means "mother." Your thumb is your "ibu jari", your mother finger.

Is this spate of eruptions associated with area's recent very-high rainfall ??
Beyond mud-slides destabilising / relieving edifice flanks, underground pressures must rise as the water-table alters, perhaps accessing 'hotter rocks' than the 'usual' circulation manages....

In 'level' ground, you'd get maar formation but a tall cone has more failure modes...

Tangential, I read some-where that the progressive 'great crack' thought to be driving a potential mega-slump / flank-failure on Cumbre_V, that Canary Island volcano, was serendipitously thwarted by locals. Historically, they dug multiple adits into flank to reach water table and supply cultivation. These galleries would also mitigate / relieve hydraulic pressure increases or steam generation per geysers....
