While cruising at 16;000 feet; Engine 2 Oil low pressure EICAS warning sounded. FO was PF; remained on course and altitude while I ran the QRH. It led us to the precautionary engine shutdown. Before we shut engine 2 down; I [advised] ATC; notified the FA; and requested ATC to standby. We continued on course; secured the engine; and then started communications with dispatch on a good alternate to go to. I; dispatch; and my FO agreed that ZZZ was directly below us; I think 5 miles away; and that would be the best place to go considering weather and such. I advised ATC of our intent; got vectors for a few minutes to run the precautionary engine shutdown QRH; and briefed with FO on the approach. I'll add he did an excellent job as PF all the way down to approach. I felt that my experience would best suit this situation for the landing so at about 12 miles out I acted as PF for the remainder of the flight. The FA was given a final brief at 3 miles out. We landed and taxied to the gate. I apologized to the passengers for the inconvenience as they deplaned; most were in good spirits as they made their way to the ticket counter for alternate plans.Threats - Engine 2 low oil pressure.Errors - I did notify the FA; spoke with her probably 5 times from encounter to landing; 15 to 20 minutes; but I didn't tell her to brace before landing as I probably should have. It did happen very fast. I felt like we were always in control including the approach and landing. Quite uneventful but nerve racking.Errors - Could have given a PA to passengers. I should have made time for that.Behaviors - Stay calm and react as you were taught; use all available sources to make the correct decision. Keep everyone in the loop; maintain control and keep a level head. The aircraft flies pretty well if you manage the emergency correctly.
EMB145 Captain reported low engine oil pressure led to shutting the engine down and a successful diversion.
