最近的火山喷发不同于普林尼式火山喷发，不属于裂缝喷发，而更像是管道爆裂。

The recent eruptions hadn't been classic, spouting-out-the-top types, so-called Plinian eruptions, but rather fissure eruptions, like bursting pipes.

列入关注的理由： 默拉皮火山属于普林尼式喷发，大约每千年大规模爆发一次（喷涌而出的岩浆总量可达1立方千米，漫天飞扬的火山灰足有20至50千米高）。

Reasons to worry: Merapi is capable of producing a Plinian eruption (spewing at least 1 cubic kilometer of magma and producing 20 to 50 kilometer-high ash columns)every 1,000 years or so.
