USGS is reporting a magnitude 4.0 earthquake near Palomar Observatory on Sunday morning.
VALLEY CENTER, Calif. – Did you feel it?
People across San Diego County are reporting that they felt an earthquake on Sunday morning. USGS reports a magnitude 4.0 earthquake near Palomar Observatory at 9:46 am after it was first reported at magnitude 4.1.
The core was located 2.9 miles from Palomar Observatory, 17.7 miles from Escondido and 25.6 miles from Oceanside.
Residents across San Diego County from Escondido, Oceanside, Chula Vista and elsewhere are posting on social media that they felt the quake.
The quake was measured at 13.7 miles deep, the USGS said.
Escondido police and fire officials said there were no immediate reports of any damage.
In Escondido we felt 2 quick jolts, The second felt bigger. It shook my house and set my heart racing 😳

What are the 3 ways of measuring earthquakes?
Seismograph is the main earthquake measurement tool. The seismograph produces a digital graphic record of the ground motion caused by the seismic waves. The digital recording is called a seismogram. A worldwide network of seismographs detects and measures the magnitude and duration of earthquake waves.
- How is the Richter scale measured? Richter scale and how it measures the magnitude of an earthquake. The Richter scale calculates the magnitude (magnitude) of an earthquake from the amplitude of the largest seismic wave in the earthquake recorded by a seismograph. … Each increase of one unit on the scale represents a 10-fold increase in the magnitude of an earthquake.
- How Do We Measure the Size of an Earthquake?
- Wave Amplitude, Lake Size, Slip Size. There are several ways to measure the magnitude of an earthquake. …
- Richter scale. Charles F. developed the first widely used method, the Richter scale.
How many ways do we measure earthquakes?
The Minute Size Scale. …
How are earthquakes are measured?
Mercalli scale.
What unit are earthquakes measured in?
There are two ways in which scientists quantify the magnitude of earthquakes: magnitude and intensity. You have probably heard of the Richter scale which is still used for small earthquakes, but most large earthquakes are often described using the magnitude scale of the moment (see below).
What is an earthquake How is it measured?
Seismographic network records earthquakes. Each seismic station in the network measures the ground motion at that site. … The Richter scale measures the largest wiggle (amplitude) on the recording, but other magnitude scales measure different parts of the earthquake.
What scale is used to measure earthquakes now?
The volume is based on the measurement of the maximum movement recorded by a seismograph. Several scales have been defined, but the most commonly used are (1) local magnitude (ML), commonly referred to as “Richter magnitude”, (2) surface-wave magnitude (Ms), (3) body wave magnitude ( Mb). ), and (4) minute size (Mw).
How big was the earthquake a few minutes ago?
Earthquakes are measured using seismographs, which monitor the seismic waves traveling through the Earth after an earthquake. Scientists have used the Richter Scale for many years but now they largely follow the “minute size scale,” says the US Geological Survey which is a more accurate measure of size.
The Richter Scale is probably the best known scale for measuring earthquakes but is rarely used today as it has been replaced by other more accurate and / or useful measures.
