    Yes it would be bad.....but at least we only have the one that can be that bad. Australia is in the cross hairs of 3 or 4.

    More than 220 dead as tsunami strikes Indonesia: Giant wave wipes out pop concert killing two band members as hundreds are injured and villages destroyed after Krakatoa volcano erupts
    • Indonesia's Disaster Mitigation Agency said at least 168 people have been confirmed killed in the tsunami
    • 800 more people have been injured after the wave hit beaches around the Sunda Strait and 20 are missing
    • It is believed the wave was caused by seismic activity from the volcanic eruption on nearby Krakatoa
    • Pilots operating in the region have been warned about a volcanic ash cloud spreading from the eruption site
    • Boy band Seventeen were performing when the tsunami struck killing two members and two crew

    Well the Sunda Strait is a tsunami hazard waiting to happen.....and they have little or no warning.

    Sounds like they should take some new preparation measures.

    Krakatoa was destroyed in the 1883 eruption and Anak Krakatoa (child of Krakatau) emerged later. Same location different volcano.

    There is vague evidence of an even larger eruption from Krakatoa in 536AD.....and another major one in the 1300s. I'll have to track down my book on the topic.

    Okay, then it can be a close second. You'd probably say no that's Long Valley caldera. Nice to see you stopping by.

    Most dangerous is usually the intersection of likelihood and location.

    Yellowstone eruption could make most of the US uninhabitable.

    But the "dangerous" ratings usually come from coastal types that have contempt for "fly over country".

    Whoops - thought I would look up official information:
    Supervolcano VEI-8

    Supervolcano - Wikipedia

    La Garita Caldera

    In Colorado is the largest eruption we know of, ever, with 5000 km3 of ejecta.

    Many of the rest are part of the Yellowstone system or in New Zealand.

    Fortunately La Garita last erupted about 28 million years ago.
