Where is andrija mohorovicic from

Mohorovicic's father, also named Andrija or Andrew , was a maker of anchors. The young Mohorovicic loved the sea, and married a sea captain's daughter.

He taught for nine years at the Royal Nautical School in Baka. After becoming director of the Meteorological Observatory in Zagreb, in , he studied and wrote primarily about clouds, rainstorms, and high winds. After a severe earthquake in , however, Mohorovicic and his colleagues petitioned their government to establish a seismic station in Zagreb.

In , Mohorovicic published his account of the earthquake of November 9, He was even able to calculate how far down the discontinuity lay—about 30 miles. The first image above is a colored diagram of the layers of the earth, in which layer 1 is the crust, layer 2 the Moho, and layer 3 the upper mantle. His paper was published in the Godiesnj Izvjesce Yearbook of the Meteorological Observatory of Zagreb in see second image above. His career began with a teaching post in the Zagreb gymnasium and then secondary school in Osijek.

On November 1, he began to teach at the Nautical School in Bakar, near Rijeka, where he remained for nine years. This is where he first came into direct contact with meteorology, which he taught at the Nautical School, and which absorbed him to such a degree that he founded a meteorological station in Bakar in He started to make systematic observations and measurements, constructing instruments of his own design to measure the horizontal and vertical velocity of the clouds.

He was meticulous in his daily work. Much later, in , in his "Instructions for the observation of precipitation in Croatia and Slavonia", he wrote: "Anyone not used to performing his work conscientiously, should not be involved in observing precipitations". At his own request in , he was transferred to the secondary school in Zagreb. On January 1, he became the head of the Meteorological Observatory on Gric in Zagreb, where he continued to work in the meteorological observatory, establishing a service to all of Croatia, all the while simultaneously teaching geophysics and astronomy at the university.

Among the extraordinary meteorological phenomena that he observed was the tornado in Novska on March 31, that took ton railway carriage with 50 passengers and threw it at a distance of 30 metres.

He also observed the vijor whirlwind near Bazma in , and studied the climate in Zagreb, and in his last paper in meteorology discussed the decrease in atmospheric temperature with height.

The accumulated date of his obvservations of clouds represented a basis for his doctoral thesis "On the observation of clouds, and the daily and annual cloud period in Bakar" presented to the University of Zagreb and which gained him his degree as doctor of philosophy in The Mohorovicic Discontinuity, named in his honor, is the boundary between the Earth's crust and the mantle.

Mohorovicic, a native of Croatia, was trained in mathematics and physics, but developed an interest in meteorology. He became head of the Meteorological Observatory in Zagreb in , and eventually was the overseer of the meteorological services for all of Croatia and Slavonia. By the turn of the century, Mohorovic's curiosity had expanded from weather to geophysics, and he was able to acquire some advanced seismographs for the Observatory.

These were deployed in time to capture readings from a strong earthquake in the Kulpa Valley. Mohorovicic was surprised to find that some readings reached his instruments faster than he had thought possible. He deduced that some of the seismic waves were traveling through a deeper, denser portion of the Earth, now called the mantle, while slower waves traveled through the crust.

The mantle starts at about 35 km below the surface of the continents, but only about 7 km below the surface in some parts of the ocean.
