Volcanic eruptions, floods, landslides
Lunar Tides: the moon's gravitational pull on the Earth is strongest at this time, because it is closest, causing especially high and low tides.
Solar Tides: the sun's gravitational pull on the Earth is strongest at this time, causing especially high and low tides (although it's not as powerful as lunar tides).
Spring Tides: named for when the tides "spring" forward during New and Full Moon's, because of how strong/weak the moon's gravitational pull is.
Neap Tides: the tides are especially mediocre at this time, because the sun and moon are at a right angle and pulling in opposite directions.
Spring and Neap Tides occur twice every moon cycle, which lasts 28 days, so every two weeks.
