Arrival of 1st p-wave – 1st s wave determines the distance away from the earthquake the station isiii. Travel-time graph1. They plot the info on the map, and find where the three meetThese notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute.XXXVI. Measuring the size of the earth quakea. Intensityi. Degree of earth quake shaking at a given location based on amount ofdamageMagnitudeii. Amount of energy released at the source of the earth quakeiii. Magnitude on a graph: ML= Richter scale. 1. Line goes from distance to amplitude and where the line crosses the magnitude scale, that is the magnitude. XXXVII. Mercalli intensity scalea. Intensityi. Based on specific damageb. Variablesi. Earthquake magnitudeii. Distance from hypocenteriii. Type of rock or sediment1. Soft sediments amplified by earthquake surface waves2. Steep slopes can generate landslides when
