But the risk assessors’ pendulum seems to have swung the other way. Data and alarms about tremors are being issued regularly, triggering school closures and building evacuations. But how useful is this information? Ruth Alexander speaks to Ian Main, professor of seismology and rock physics at Edinburgh University in the UK, who puts the risks into context.
