Eruptive activity at Turrialba Volcano resumed Monday with two new explosions, one of which reached nearly 4,000 meters (13,100 feet) in height, according to reports from the National University (UNA).
The first eruption of Turrialba, located in Cartago province, some 50 kilometers east of San José, occurred at 2:53 a.m. and lasted about 15 minutes.
The explosion launched ashes, gases and incandescent rocks into the air to about 1,000 meters (3,280 feet) above the volcano’s crater, UNA’s Volcanological and Seismological Observatory of Costa Rica (OVSICORI) reported.
The second  explosion occurred at 11:32 a.m. and spewed material about 13,000 feet into the air, the agency said.
OVSICORI volcanologist MarÃa MartÃnez said that after the second explosion, reports were received of ash falling in communities north and west of San José, including Coronado, Moravia, Tibás, Guadalupe, Escazú and as far away as Alajuela province.
A report from the University of Costa Rica’s National Seismological Network (RSN) states that the second explosion lasted about 13 minutes. RSN volcanologist Raul Mora said the explosion also launched a large amount of gas, ash and rocks into the air.

Flights delayed
Ashfall over the runways at Juan SantamarÃa International Airport prompted a temporary closure of the airport at 1:15 p.m.
Silvia Chaves, a spokeswoman for Aeris, the company that operates the airport, said the preventive closure caused the delay of eight departures and four arrivals.
Chavez said the airport will evaluate the reopening of the airport, pending the results of an inspection.
The Aviation Administration also confirmed the temporary closure of TobÃas Bolaños Airport, west of San José.
Both terminals resumed their normal operations at around 4 p.m.
Eruptive activity at Turrialba restarted last Sept. 13, following 44 days of minor events.
The Cartago volcano is one of Costa Rica’s five active volcanoes, along with Arenal, Poás, Irazú, and Rincón de la Vieja.
