Here's an analysis piece from a pretty reliable analyst:

Early days yet and offered with the usual caveats:
High-order detonation of ~2,700 tons of ammonium nitrate stored in bags in a dockside ware house probably equalled ~240 tonnes of TNT
Numerous, smaller pre-detonation explosions caught on film.
3.5-3.7 shock on the Richter Scale
Shock wave rattled windows in Cyprus
Large crater in the harbour now visible at scene of detonation.
Beirut customs officials had been trying to make the seized chemicals go away for several years. Pre-detonation photos of the warehouse show pretty sloppy storage and handling.
