Volcano Erupts Near Sonsonate, El Salvador

I fear this could be bad. I know this area well, having spent quite a bit of time in El Salvador recently. The volcano is about 15-20 miles from Sonsonate, El Salvador's second largest city and is just north of the country's main east-west highway.
As one drives between the two cities, one sees huge volcanic boulders and lava flows on both sides of the road, so it's entirely within the volcano's power to destroy that road.
