Does Honolulu have earthquakes?
GeologyHawaii’s biggest earthquakes, up to magnitude 7.8, are associated with dike intrusions into the active volcanoes and expansion of the volcanoes across the old seafloor. While we can feel such events in Honolulu, they occur too far away to cause any damage here. How often does Honolulu have earthquakes? Additionally, the State experiences, on average,

What are the three types of volcanic landforms?
GeologyThe three types are composite volcanoes, shield volcanoes, or cinder cone volcanoes. How many types of volcanic landforms are there? Volcanic landforms are categorised into two types: extrusive and intrusive landforms. This division is done based on whether magma cools within the crust or above the crust. By the cooling process of magma different types

What is the scale for earthquakes?
GeologyThe Richter scale measures the largest wiggle (amplitude) on the recording, but other magnitude scales measure different parts of the earthquake. The USGS currently reports earthquake magnitudes using the Moment Magnitude scale, though many other magnitudes are calculated for research and comparison purposes. Is a 10.0 earthquake possible? No, earthquakes of magnitude 10 or larger
