Throughout Fortnite Chapter 3 Season 1, we are given several seasonal quests from The Scientist, one of the NPCs on the island. One of these quests has two parts: we need to receive the next objective at Logjam Lumberyard, then collect readings from Seismometer locations. Normally, this would be simple. However, we have to collect three readings in one match, which can make this quest more of a challenge.

Objective Guide

Logjam Lumberyard is a highly populated dropzone at the beginning of any match, so it is a good idea to avoid starting this quest right away if you’re hoping to avoid confrontation. However, if the storm circle looks like it’s going to close off the mountain area northwest of Logjam Lumberyard, you’ll want to start this quest as soon as possible.

The first thing you’ll need to do is enter Logjam Lumberyard, which is a named location in the northwest section of the map. You don’t need to reach a specific point, you just need to enter the area to receive the next part of the quest.

After you visit Logjam Lumberyard and listen to the dialogue from The Scientist, you are then required to go to the mountainous area northwest of Logjam Lumberyard and travel to several locations to collect readings from Seismometers. The Seismometer locations are marked in the map above.

Here is the list of all the Seismometer locations.

  • Next to a large bush on a hill directly west of Logjam Lumberyard’s lumberyard.
  • East of the river at the point where it runs into the north side of Pinnacle Peak.
  • Barely southwest of the Reboot Van on the north side of Pinnacle Peak.
  • Directly south of the Reboot Van on the south side of Pinnacle Peak.
  • On the north side of the large hill at the edge of the island, directly west of Logjam Lumberyard.
  • In between two very tall trees on the west side of the mountain with Seven Outpost II.
  • Next to a very tall tree on a small cliff overlooking the ocean, west of the bridge south of Seven Outpost II.
  • On the hill directly northeast of Logjam Lumberyard.
  • Near the top of the hill directly north of Shell or High Water.

There are several Seismometer locations, but the three easiest ones to get are almost directly west of Logjam Lumberyard (marked by the blue arrows). If you want to complete this quest quickly, you’ll want to grab a vehicle from Logjam Lumberyard as you leave. Even a semi-truck is a good option because it can take more damage than other vehicle.

Once you have collected readings from at least three of the Seismometers marked above, the quest is complete!
