Flooding: He is located in the drainage area of a fairly large mountain range, and the primary drainage seems to be just north of his location, so he would likely be prone to seasonal flooding, particularly since he's on a fairly flat section.
Cold Climate: Considering how far that glacier is reaching in this day-and-age with global warming and all, his location must expect pretty cold temperatures.
Volcanic Eruption: He's located fairly close to a volcano, and seemingly an active one too. (It has a red caldera, that probably signifies something.) Since it's a Stratovolcano, with steep sides, it is likely prone to explosive Plinian eruptions, which can be widely devastating over a long range. He might be far enough away to avoid pyroclastic flows, but eruption-triggered lahars (huge floods with ash and mud and everything else they pick up along the way) could reach him. Furthermore, if a collapse were to fall into the lake, it could trigger a tsunami wave. (Mt. St. Helens did this in Spirit Lake.) Not to mention he's well within range of an ash cloud, though that could depend on the wind.
Earthquakes: Granted, earthquakes can happen anywhere, but his location would likely have strong ones. The volcano so close to the coast is probably caused by a seduction zone in the tectonic plates, similar to Japan or the Pacific Northwest. These areas are prone to strong earthquakes, like the big ones that hit Japan, Indonesia, New Zealand, and Chile. (California's earthquakes are caused by a slip-zone tectonic plate boundary, which is different.) Besides the shaking, such earthquakes triggered off coast could cause tsunamis. Which brings us to...
Tsunami: His location is right next to the lagoon, which means that he would be right in the path of a tsunami. Also, since the water area is constricted by the bay, this might cause a tsunami wave to grow in size. So technically he could get wiped out from a landslide-triggered tsunami from the lake in the west OR an earthquake-trigger tsunami from the sea in the east.
Hurricanes: This depends more on the exact latitude / longitude of his location, as well as the directions of the Gulf Stream-equivalent air and ocean currents. But if a hurricane blew from the southeast, as in the Eastern US, then he would still be in trouble. Unless the hills on the peninsula are significantly large to block the winds, the storm would push through it, and the storm surge in the water would push through the bay and into the lagoon, adding more potential flooding. But there are plenty of other factors here that could make-or-break the hurricane threat. Additionally, I don’t think he’s at a great threat for tornados, which seem to rely on as collision between warm and cold air systems. Potentially, cold air could flow from the mountains while warm tropical air could blow up from the forest, creating a thunderstorm mix that could spawn tornadoes, but there’s nothing absolutely indicating that.
Meteor Impact: Okay, I guess anywhere that's above ground is prone to meteor impacts. I forget if longitude has anything to do with where they'd strike, but I don't think it does.
Dinosaur Invasion: C'mon, there's a giant mesa in the forest. Odds are, there are bound to be dinosaurs there who survived the extinction.
Granted, any location has it’s own set of risks for natural disasters, but he’s just asking for it with this location. So he just needs to be aware of the warning signs, prepare for emergencies, and have good home-owners insurance.
