When the peninsula moved

So, after the earthquake the rumor is that the peninsula was raised out of the water a meter and a half. My biggest fear is what happens when another earthquake hits that puts the peninsula back and where is all that water going to go. We don't have sirens like in Hawaii so how do I know I need to get out of my nice beach house and run for the hills?  Last night we had three earthquakes (a 4.4, 3, and 3.5) and all three woke me up. The first and last I laid in bed slightly concerned that maybe I should get up, especially since we heard the dogs all barking in the neighborhood. Luckily there wasn't a need to run from the house last night but just in case any of you would like to keep up to date with the ground moving activity here in Costa Rica, this here is the best site, it gives us more seismic activity than the USGS site.
