Costa Rica’s Turrialba has been rumbling for about a week now and at 9pm UTC Monday 4th it gave a moderate eruption which has coated as far as the country’s capital, San Jose, in ash 60km away. An ash column stood at just 2.5 km in from the eruption which lasted little over half an hour. The Juan Santamaría International Airport was closed for under 12 hours as staff worked through to clear the run way of ash, the aviation code has since been lowered and flights have resumed normal operation. When Turrialba started erupting back in March it left the airport closed for days, luckily this seems to be a much smaller eruption.
