Narrative:

After landing; [we] received hydraulic 1 fail alert. Checked synoptic and quantity was zero; ran QRH. While coordinating for tow-in to gate; tower advised smoke was observed from #1 engine so we elected to shut down the engine and have the fire crew investigate. Tower declared an emergency and rolled the trucks for us; and they confirmed fluid still leaking from the #1 engine; but could not determine if it was fuel or hydraulic fluid. We decided to shut down the remaining engines and get a tow into the gate. Maintenance confirmed it was residual hydraulic fluid. With tower's concurrence we terminated the emergency after we reached the ramp.
