We’ve just had an earthquake here. In case you’re wondering, there’s a bracha for just such an event. Now’s your chance to say it! Blessed are you haShem, our God, king of the universe, who enacts the works of creation / ‘oseh ma’asei breishit.
Not a bracha one often gets the opportunity to use. And yes, it is the same as the bracha for lightning. Nothing like having the primeval world poke its nose into our busy day and remind us of deep things.
