Potentially world-ending crises everywhere - be scared, very scared. And don't trust well-known sources, pay me, so I can keep you scared.<p>Super-volcanoes, tsunamis, asteroids - they all happen and can be catastrophic. And La Palma is a major concern - a recent bout of activity certainly should be on the agenda for countries that would be directly affected.<p>But I would recommend following other sources to remain informed. Perhaps check what your local government has to offer in the way of tsunami alerts, if you think you would be affected, because checking conspiracy mongers' websites around the clock isn't a viable alternative.
